Hi i found this,

'Wiseweather' July 2007 forecast

Summary: CET temperature 17.7C or 1.3C above average; rainfall 125% and sunshine 100%*

The average July CET 1971-2000 was 16.5C, last July 19.7C, 2005 16.9C

Issued: 29th June 1600BST

July summary

After a very wet & rather dull May and June (probably the wettest May-June period ever with around 200% of average rainfall in June, clearly far more than we envisaged) July looks likely to start on a simlar note with more unsettled weather likely for many. However the month will likely see high pressure dominant for at least part of the time we think from the 10th or so onwards and again towards the end, with positive pressure anomolies and 500mb values rather above average, especially in the north & east. However we think the west & south west (incl Wales) will see likely see lower pressure than average in the second half still with periods of rather more unsettled though quite humid weather at times. The last part of the month seems more likely to end generally warmer, though not especially settled with a SE or S'ly flow becoming established and areas of fairly weak low pressure moving up from the SW at times, some thundery.

Overall temperatures will be slightly above average on the whole for most parts, especially in the south and east, though the west may be nearer average and at least initially in most parts somewhat below average. Rainfall is likely to be rather above average again for most parts though the east may be slightly drier and the SE and NE nearer average. Sunshine will be near the long term average for most parts though perhaps a little above average in the east and SE. Winds will generally be near or slightly above average speed with thunder again slightly above average for most parts, especially in the south west. Sea temperatures will continue to be near average around the UK, having fallen from seeing earlier positive anomalies during early/mid Spring, but are generally still 2C above average in the Eastern Channel and Southern North Sea. Soil temperatures will tend to be near or slightly above average for most parts with soil moisture well above average in central and northern parts now, after the notably wet May and June.

'Wiseweather' August 2007 forecast

Summary: CET temperature 17.0C or 0.8C above average; rainfall 90% and sunshine 110%*

The average August CET 1971-2000 was 16.2C, last August 16.1C, 2005 16.2C

Issued: 31st July 1100BST

August summary

After the wettest May-July period on record, August looks likely to start drier for most in the south, whilst the north stays wetter with more unsettled weather likely for many. However the month will likely see high pressure dominant for at least part of the time in the south but we think with an often rather cool polar maritime flow across the top of the high pressure and 500mb values remaining slightly below average in the north. However we think the SE and parts of the south will see likely see periods of rather more settled, drier weather, with one or two warm plumes at times. The last part of the month seems more likely to end generally warmer, though not especially settled with a more SW'ly flow becoming established and areas of fairly weak low pressure moving up from the SW at times, some of a rather thundery nature.

Overall temperatures will be slightly above average on the whole for most parts, more especially in the south and east, though the north west may be near or below average and at least initially in most northern parts, somewhat below average. Rainfall is likely to be near or somewhat above average again for parts of the northwest though the south and east may be drier than average, though there will be some locally heavy falls. Sunshine will be near or below the long term average for parts of the north, hampered by a lot of moisture though perhaps a little above average in the east and SE. Winds will generally be near or slightly below average speed with thunder near or slightly below average for most parts.

Week 1 1st-7th August

The month looks likely to start with low pressure to the north west of Scotland and high pressure across the south with slow moving showery fronts or troughs moving down across the UK. Plenty of showery rain in the first few days then especially by day and it will be heavy locally inland across England & Wales and possibly thundery in places. The south & east driest and warmest. More rain, some heavy across north western upslopes by the 3rd into the north, as a very warm air mass moves up across the UK, this partly formed from an ex-tropical depression. A lot of cloud everywhere, clearing on Saturday in the south and east though to give some quite high temperatures. A fresher airmass soon moving across from the west though giving a period of quite heavy thundery showers in places as it does so with at least the potential or some heavy downpours in central parts. The week ending on a fresher cooler note everywhere, as pressure rises again with a few showers in the north and east and some misty quite chilly nights here too.

Temperatures generally warm to start especially in the south, perhaps 2-5C above in southern & eastern parts, so feeling very warm here. The north and west staying nearer average and cooler though, and later a few degrees below the average, especially in Scotland, though nights will not be especially chilly in the south throughout. Rainfall below average in the south and east at 5-15mm but above average in the north and parts of the west where perhaps 25-40mm may fall and locally up to 50mm in the NW with sunshine near or rather above average especially in the south and east due to the influence of the high pressure and then the NW'ly flow.

'Wiseweather' September 2007 forecast

Summary: CET temperature 14.9C or 1.2C above average; rainfall 80% and sunshine 120%*

The average September CET 1971-2000 was 13.7C, last September 16.8C, 2005 15.2C

Issued: 31st August 1300BST

September summary

The wet summer weather is a thing of the past now as drier weather took over from mid August for many and September looks set to see a lot of rather warm, dry weather about generally for most areas. With areas of high pressure initially dominating across the UK in the first half it will stay notably dry and warm though with some misty or foggy nights, though not especially cool ones. Later in the period we expect it to become more unsettled though in the north and NW especially as low pressure systems move across or to the north west of these areas whilst the south stays mainly dry and somewhat warmer. As short lived southerly flows develop a few plumes of warm air aloft and at the surface may give some high late maxima with the risk of showers development here at times in the SW and south.

Overall temperatures will be rather above average on the whole for most parts, more especially in the south and east, though the north west may be nearer average. Rainfall is likely to be somewhat or well below average again for parts of the east and south though the northwest may be nearer average. Sunshine will be rather above the long term average for many parts especially in the east. Winds will generally be rather below average speed with thunder near or slightly below average for most parts. Sea temperatures are about one-two degrees above average for much of the UK, except down in the SW and the far Scottish northern Islands, where they are slightly below average, this negative anomaly likely to persist. Soil temperatures will tend to be slightly above average for most parts with soil moisture now decreasing to near or only slightly above average for many areas, despite the rainfall earlier this summer.

Week 1 1st-7th September

The first few days of September look likely to see high pressure to the south-west or south and low pressure crossing to the north allowing fronts to bring cloud and rain at times across N Ireland, Scotland and the north of England. It should stay generally fine and sunny in south and south east though in the main but Wales and the south-west will see more in the way of cloud. By the 3rd a rather muggy airstream up across the north-west will allow further fronts to affect western and northwestern parts with one fizzling out across the south though initially giving some mainly light rain and plenty of patchy low cloud quite widespread whilst the north and north west stays generally cloudy and wet at times again; some sea fog around the south-west and Welsh coasts too. By the 4th onwards though through to the following weekend it should become more settled across most parts, with high pressure over the south-west in control but early fog patches are likely in central areas and some weak fronts may affect the north-west still and generally there will be a lot of cloud about, best of the sunshine initially in the west and south-west but by Friday with the high pressure dominating across the UK there should be long sunny periods nearly everywhere though prone valleys may take a while to see the sun shine though, as the mist and fog patches may become quite dense overnight in these inland valleys.

Temperatures generally near average to start, especially in the south, perhaps a few degrees below the average for a time in the north by day, though nights will be fairly mild. Later on in the week it may become warm or very warm inland at times, more especially in sheltered inland parts of England and Wales. Rainfall well below average in the south and east where it'll be basically dry but still below average in the north and west too where perhaps 5-15mm may fall and with sunshine rather above average, especially in the Midlands, south and west due to the influence of the high pressure.

'Wiseweather' October 2007 forecast

Summary: CET temperature 11.7C or 1.3C above average; rainfall 85% and sunshine 115%*

*The average October CET 1971-2000 was 10.4C, last October 13.0C, 2005 13.1C.

Issued: 30th September 1245BST

October summary

A rather blocked set up looks set to continue into the first half of October, as we intimated in our Autumn forecast. A generally S-SE'ly flow predominating initially with high pressure to the east so as fronts affect the west and south they will be slow moving, allowing generally unsettled weather with quite a lot of rain in places for a few days. However they will tend to peter out and as high pressure ridges in from the south west again, it will become fairly settled with mainly dry, though not especially warm weather predominating. Some fog by night , especially in central areas with the risk of frost in places too in the north. By the middle of the second week a more S-SE'ly flow may well develop again repeating the pattern, as high pressure moves to the east and this could allow some slightly warmer air up across the south for a time, though there may be showers in the SW, as well as further fronts moving in from the west, allowing a breakdown giving cloud and rain here, this affecting other central and southern parts around mid month. With high presure dominating the third week of October it seems that fronts will struggle to make much leeway into western and central areas of the UK and the east may be affected by showers especially across the SE, some heavy. Low pressure may develop to the SW or south allowing temporary easterly flows, with the risk of more frost and fog than normal though especially in central and northern parts in this period. Eventually deeper autumnal low pressure systems will develop to the NW of Scotland and the last week looks likely to be more unsettled with a mix of mild SW'ly winds but increasingly spells of cooler NW'ly polar air being drawn SE across the UK towards the month's end with brief ridges of high pressure at times giving a few nights of frost and mist patches in places.

Week 1 1st-7th October

The week looks set to start with high pressure to the north east with a light SE'ly flow across the UK. Nights will be misty with a few fog patches inland especially in the north of England and Scotland. It will be mainly dry with decent sunny periods across most of the UK, north of the Midlands but initially the south will see more cloud and outbreaks of showery rain, heavy in places possibly with localised thunder. Showers will also develop further west across Wales and the SW but they should be mainly light and well scattered . From midweek high pressure will still dominate to the north east as a mainly light S'ly flow covers the UK with some mist and low cloud patches almost anywhere overnight, these a little slow to clear in the mornings. Good sunny periods for most parts of the NE and eastern UK but as a weak front pushes into the north west and a weak area of low pressure lies across the south cloudier here and to the west with showers or showery rain developing, especially across the SE , N Ireland and NW Scotland, possibly heavy and thundery with some heavy falls in the far SE with a risk of local flooding. By the end of the week lower pressure will develop to the NW allowing a SW'ly flow to establish and the weekend will see some cloud and rain in the NW but it should remain drier though humid elsewhere with sunny periods though a lot of mist and low cloud will affect western and SW'ern parts as the high moves away towards Scandinavia but a new high pressure area forms across the southern UK and moves NE into the southern North Sea by the weekend.

Temperatures generally near average, perhaps a few degrees below the average for a time in the north by day, though nights will be fairly mild. Later on in the week it may become fairly warm at times, more especially in sheltered inland parts of southern England and Wales with mild nights. Rainfall near average in the south and west but possibly some heavy falls in the SE on Wednesday; still slightly below average in the north and west where perhaps 10-15mm may fall with sunshine near average, possibly slightly above in the Midlands and NE due to the influence of the high pressure.

'Wiseweather' November 2007 forecast

Summary: CET temperature 7.1C or 0.2C above average; rainfall 75% and sunshine 110%*

*The average November CET 1971-2000 was 6.9C, last November 8.1C, 2005 6.2C.

Issued: 31st October 1230Z

November summary

Continuing with a rather blocked set up well into the first half of November as we suggested in our Autumn forecast. In fact the forecast below is almost exactly the same as the one we issued at the end of August. A generally anticyclonic or S'ly flow predominating initially with high pressure generally close to the UK or to the east so as fronts affect the west they will be slow moving, allowing generally unsettled weather especially for the NW; however they will tend to peter out and as further areas of high pressure ridge in from the south west , it will be fairly settled with mainly dry weather predominating in the south and east with some fog by night and the risk of frost in a few prone places too. Short lived cooler outbreaks of N-NWly winds will occur as low pressure slips away SE into Scandinavia and high pressure develops from the west. This pattern may be repeated for a few times until well into November. Eventually deeper autumnal low pressure systems will develop to the west and the last ten days looks likely to be more unsettled with a mix of W'ly winds but spells of cooler polar air being drawn SE across the UK towards the month's end with brief ridges of high pressure at times giving a few nights of frost and mist patches in places.

After a notably mild start, temperatures will be near or slightly above average on the whole for most parts, more especially in the north and far south, central parts may see generally near average days but some rather chilly nights. Rainfall is likely to be somewhat below average again for most parts, especially across the east and SE though the far northwest may be at least nearer average. Sunshine may well be a little above the long term average for some parts, especially in the south but below average in central areas prone to mist and fog. Winds will generally be rather below average speed with thunder below average for most parts.

Sea temperatures staying about a degree or two above average for much of the UK but cooler in the SW where the SW approaches will be slightly below average and also in the far north where they will be nearer average though the large negative anomalies of early October have dissipated.Soil temperatures will tend to be slightly above average for most parts with soil moisture rather below average for central and eastern parts but nearer average elsewhere.

Week 1 1st-7th November

The month will start dry and settled for most across England and Wales though fronts will affect the north west especially givig a lot of cloud and some outbreaks ogf rain here with breezy Sw'ly winds. it will be notably warm in parts of the south also. By the weekend it looks likely high pressure will pull back west of Ireland with a somewhat cooler NW'ly flow across the UK though soon sinking south again to lie over the southern half of England as further fronts affect the north and NW by Sunday. The south generally staying dry and fairly bright though there will tend to be a lot of overnight mist and low cloud around only partially clearing by day. The north and NW and parts of N Wales too will be cloudier with some light rain extending SE from the northwest, giving a lot of cloud, it'll be breezy for a time in the north too but winds generally very light or calm elsewhere. Through all the following week a repeat of this event seems likely to take place with another area of high pressure trying to build eastwards across the UK but lying predominently to the west allowing a weak NWly flow at least initially across the north and east and so it will be dry generally everywhere by day though probably rather cloudy at times though certainly breaks will occur by night and day. Where they do some chilly nights likely especially in prone valleys such as the Thames, with local ground frost and mist or fog patches in places then bright periods probably developing by day especially down in south eastern and southern parts but low cloud persisting in many central areas. To the north west some light showery rain around at times, the week ending as it begun, high pressure over the south and a more W-SW'ly flow across the north with some showery rain at times and quite breezy in the far north. Some of the showers or showery rain could be rather wintry in nature over mainly Scottish hills during the week.

Temperatures generally near average after a mild start, perhaps a few degrees below the average for a time in the north by day, and locally in other parts where fog and low cloud persists by day. Later on in the week it may become fairly mild again at times, more especially in coastal parts of southern England . Rainfall well below near average in the south and west but possibly some heavy falls in the SE on Wednesday; still slightly below average in the north and west where perhaps 10-15mm may fall with sunshine near average, possibly slightly above in the Midlands and NE due to the influence of the high pressure.

'Wiseweather' December 2007 forecast

Summary: CET temperature 6.4C or 1.3C above average; rainfall 115% and sunshine 100%*

*The average December CET 1971-2000 was 5.1C, last December 6.5C, 2005 4.4C.

Issued: 29th November 1200Z

Monthly summary

A rather unsettled start well into the first half of December seems likely. A generally cyclonic flow predominating initially with high pressure generally well to the south or SW as a series of depressions and associated fronts affect the UK, sometimes slow moving, allowing generally unsettled weather especially for the west with a short lived colder period perhaps occuring for a while though, in the north especially. By mid month it will probably become more settled generally across much of the UK although the far NW may stay more unsettled but it should be reasonably dry in most parts with some fog and frost at night. Pressure will probably fall again by the third week to give more unsettled weather with rain at times everywhere. It could become very unsettled again for a time but just after Xmas a colder more N'ly flow seems possible again but milder weather seems likely to be pushing into the west by New Year, as some quite deep depressions run rapidly east north east on a strong Atlantic jet. After a notably mild start, temperatures will be near or slightly above average on the whole for most parts, more especially in the north and far south, central parts may see generally near average days but some rather chilly nights. Rainfall is likely to be somewhat below average again for most parts, especially across the east and SE though the far northwest may be at least nearer average. Sunshine may well be a little above the long term average for some parts, especially in the south but below average in central areas prone to mist and fog. Winds will generally be rather below average speed with thunder below average for most parts.

Sea temperatures staying about a degree or two above average for much of the UK though nearer average in the SE and the far northern Isles; soil temperatures will tend to be slightly above average for most parts with soil moisture a little below average for many parts but nearer average in the west.

Week 1 1st-7th December

The month seems set to start with low pressure across the UK and a rather breezy cloudy period as showery bands of rain swing east across the country, showers will be on the heavy side with the risk of hail and thunder and possibly wintry over northern uplands at times. A deep area of low pressure seems likely to develop on the 2nd and run across England with a lot of rain and gales to the south and west. Mild nights generally here with a lot of cloud around but by the 3rd it looks likely to there will be a brief ridge of high pressure across the UK with some local frost in prone places especially in the north, mist patches persisting by day in the valleys but more rain soon reaching the west bringing cloudy weather to most parts with drizzle and fog near coasts and hills- just a chance of some wintryness over highest hills in the NW and this front straddles the UK for a day or so with a mainly SE'ly flow to the NE, more SW'ly in the SW and a strong temperature contrast NE/SW giving some patchy rain at times, possibly wintry over hills in the NE. More low pressure likely to end the week up to the NW with further rain or showery rain moving in from the west probably.

Temperatures generally near average or above average and very mild midweek in the south and west especially, chilly in the NE at times though. Rainfall near average for most parts and possibly some heavy falls in the west at times. Sunshine probably rather below average especially in the west but only slightly below for most parts and quite close to average in the east.
