  1. Day 2 Convective Outlook VALID 06:00 UTC Thu 31 Mar 2016 - 05:59 UTC Fri 01 Apr 2016 ISSUED 16:25 UTC Wed 30 Mar 2016 ISSUED BY: Dan Sharp upper trough will migrate eastwards across the British Isles on Thursday, accompanied by cold mid-levels. This, combined with diurnal heating, will generate a couple hundred Jkg-1 CAPE, with orographic forcing / low-level convergence playing a key role in developing a few scattered showers and/or isolated thunderstorms, primarily through the afternoon and into the early evening. Isolated heavy showers could develop almost anywhere, but the main focus being highlighted by the ISOL areas, but even here the chance of lightning is still considered quite low. Slow storm-motion and/or back-building will result in some locally prolonged heavy downpours, perhaps causing some localised surface water flooding - especially across parts of NE England and S/SE Scotland. A highly-sheared environment across these areas as a northerly jet encroaches from the Atlantic suggests that environmental conditions will be more favourable for lightning across N + E England and S Scotland. Small hail may accompany any stronger cells. http://www.convectiveweather.co.uk/forecast.php?date=2016-03-31
  2. Day 2 Convective Outlook VALID 06:00 UTC Wed 30 Mar 2016 - 05:59 UTC Thu 31 Mar 2016 ISSUED 16:55 UTC Tue 29 Mar 2016 ISSUED BY: Dan Broad upper trough across British Isles will lift northwards as the main jet stream core bulges northwards across southern Britain. At the same time, upper trough axis west of Ireland will continue to approach from the Atlantic, while sharpening. Therefore, yet another day of widespread but low (non-zero) chance of lightning, particularly so from the Bristol Channel - The Wash northwards, with cold mid-levels combining with diurnal heating to generate 200-300Jkg-1 CAPE. Expect scattered showers, particularly in northern and western areas, with a low spot-location chance of lightning - in general, areas most likely to see this are C / E Ireland. Have extended the ISOL towards S/SE England and Home Counties, despite the lack of any significant instability, to cater for the (low) risk of lightning given the highly sheared environment as the jet stream continues to migrate slowly northwards, perhaps inhibiting the depth of convection somewhat. There will likely be a lot of medium/high cloud spilling northwards, but nonetheless a few scattered showers may develop and drift slowly eastwards, aided by low-level wind convergence. Shower training may occur here. Once more, small hail is likely in any stronger cells that develop. http://www.convectiveweather.co.uk/forecast.php?date=2016-03-28
  3. I was at Inverness Retail Park and the hail was bad
  4. VALID 06:00 UTC Tue 29 Mar 2016 - 05:59 UTC Wed 30 Mar 2016 ISSUED 21:15 UTC Mon 28 Mar 2016 ISSUED BY: Dan Very broad upper trough will be in place across the British Isles on Tuesday, with shortwaves running eastwards along the trough base serving as a focus for more organised areas of showery precipitation. One such pronounced feature is expected to arrive in far SW Britain around midday, and then run eastwards across southern Britain through the afternoon / evening. However, most NWP suggests this will be largely dynamic in nature, and hence the lightning risk along this feature is considered fairly low. Otherwise, it is generally another day of widespread, but low chance, lightning potential, perhaps the best environmental conditions to be found across C / E Ireland during the afternoon, but potential here is still too low to consider a SLGT. Once more, small hail is likely in any stronger cells that develop. http://www.convectiveweather.co.uk/forecast.php?date=2016-03-28
  5. Day 2 Convective Outlook VALID 06:00 UTC Mon 28 Mar 2016 - 05:59 UTC Tue 29 Mar 2016 ISSUED 18:53 UTC Sun 27 Mar 2016 ISSUED BY: Dan Broad upper trough will migrate slowly eastwards across the British Isles on Monday, while sharpening. At the surface, a deep area of low pressure will clear eastern England during the morning, with cold mid-levels following in its wake, steepening lapse rates due to a combination of relatively warm SSTs and diurnal heating inland. Showers will affect western and northern coastal areas throughout the day, with particular attention given to Shetland at first in the morning, and more especially SW then S Britain during the afternoon and evening. Here, 200-300 Jkg-1 CAPE and ELTs down to -40C suggest that some sporadic lightning activity is likely, but not widespread/frequent enough to warrant a SLGT based on latest guidance. Once again small hail is likely in any stronger cores that develop. http://www.convectiveweather.co.uk/forecast.php?date=2016-03-28
  6. UK Outlook for Monday 11 Apr 2016 to Monday 25 Apr 2016: Early indications suggest that the progression of frontal systems from the Atlantic may well remain somewhat limited as high pressure to the east or northeast of the UK looks to dominate. This brings the increasing chance of longer drier spells of weather, particularly across the north, with southern and south-western areas on balance seeing the greatest chance of rain or showers. Overall temperatures look to average around around normal, but with some warmer spells at times. Updated at: 1216 on Sun 27 Mar 2016 http://www.metoffice.gov.uk/public/weather/forecast
  7. Outlook for the UK over the next 6-30 days UK Outlook for Friday 1 Apr 2016 to Sunday 10 Apr 2016: Fine and settled for many to start April, but thicker cloud and outbreaks of rain in the northwest will make erratic progress southeastwards, with clearer but showery conditions following behind. Thicker cloud and showery rain may also push in from the south at times too. Through the weekend and into the following week we will likely see a build of pressure towards the east or northeast of the UK and low pressure staying to the west. This means we may see rain affecting western areas at times, but with many eastern, and perhaps northern parts staying mostly dry. After a fairly cool start, with overnight frosts, some warmer spells are likely, especially in the south and southeast, but this may ease off towards average with time.

  8. Ok not posted for a long time here go Day 2 Convective Outlook VALID 06:00 UTC Sun 27 Mar 2016 - 05:59 UTC Mon 28 Mar 2016 ISSUED 08:56 UTC Sat 26 Mar 2016 ISSUED BY: Dan Upper trough swings NEwards across British Isles through Sunday, with cold air aloft steepening lapse rates in response to diurnal heating. Scattered showers and a few weakly-electrified thunderstorms will develop, sometimes becoming organised into bands, with the greatest chance/coverage of lightning expected in the two SLGT areas - moreso in the eastern zone from S Yorks down to Lincs. Even so, only a low-end SLGT has been issued, but for many it will be the first proper convective day of the year. Small hail is likely to accompany some of the showers, and given some LLS, particularly in the eastern SLGT, there is scope for perhaps a funnel or weak tornado. http://www.convectiveweather.co.uk/forecast.php?date=2016-03-27
  9. yes had some snow here this morning but it turn milder few hours later
  10. yes not got above freezing here to but starting to come up now
  11. let see what 12z run bring if ECM downgrade it then worry
  12. UK Outlook for Saturday 2 Jan 2016 to Monday 11 Jan 2016: The first week of New Year is likely to be unsettled, with spells of wet weather, and some snow possible over the higher ground of the north. This may be accompanied by strong or gale force winds, with a low risk of severe gales. The wet conditions are likely to be mixed with some brighter, showery interludes and also some brief drier spells. As we move into the second week of January there are signs of an east to west split developing, with mild, wet weather in the west and colder drier weather in the east. Temperatures are generally expected to remain around or just above normal for most, but slightly below at times with some night frosts possible in the settled, drier spells http://www.metoffice.gov.uk/public/weather/forecast
  13. but some time met office come on board After a few days
  14. Today's daily update slightly increases the chance of a White Christmas in the north and the south. The next couple of weeks are expected to bring mostly mild or very mild weather but there are indications that Christmas itself could coincide with a colder interlude. The greatest risk of snow remains over higher ground in the north. At this stage a green Christmas remains the favoured outcome for most of the UK. Snow remains possible in the north, particularly over high ground. Daily updates will continue until becomes possible to call the Christmas Day weather. Probabilities of snow falling on Christmas Day North of Yorkshire / Lancashire: 19% South of Yorkshire / Lancashire: 8% Forecast issued Update 12, 12/12/2015 The computer says [Issued 12/12/2015 09:17:53] The regional Christmas weather predictions are updated daily using medium and long range forecast data. They may indicate very different prospects to the TWO forecast above. Who will be right? It's expected to be too mild for snow in the south. It's expected to be too mild for snow in Wales. It's expected to be too mild for snow in the Midlands. It's expected to be too mild for snow in the north. Cold but dry conditions are expected in Scotland It's expected to be too mild for snow in Northern Ireland. Cold conditions in the Republic of Ireland are expected. Marginal for rain or snow. It's expected to be too mild for snow in the Netherlands http://www.theweatheroutlook.com/forecast/Christmas-weather-forecast
  15. UK Outlook for Monday 21 Dec 2015 to Monday 4 Jan 2016: The latest indications are that unsettled conditions will dominate across the UK at first with Atlantic weather systems bringing outbreaks of rain and strong winds to many areas. Later in the month there is a possibility of some drier and colder weather developing, however there is significant uncertainty in the forecast and some rain is still possible at times. Temperatures are likely to vary from day to day, with mild conditions at times associated with frontal systems, then some colder interludes between. Mild conditions become less likely towards the end of December. Updated at: 1318 on Sun 06 Dec 2015 http://www.metoffice.gov.uk/public/weather/forecast
  16. UK Outlook for Friday 11 Dec 2015 to Sunday 20 Dec 2015: Colder and brighter on Friday with a mixture of sunshine and showers, these heaviest and most frequent in the northwest where they will be blustery and wintry on high ground. It may then become dry for a time away from the northwest before milder, wetter and windier weather returns to the southwest through Saturday, this spreading northeastwards across all areas by the end of the weekend. Thereafter it is likely to remain unsettled for all areas with showers or longer spells of rain, particularly in western areas, while eastern areas should enjoy occasional drier periods. It is likely to be windy at times with showers falling as snow over northern hills. Temperatures will generally be around average, although with some frosty nights possible under clear skies, particularly at first. http://www.metoffice.gov.uk/public/weather/forecast
  17. UK Outlook for Sunday 20 Dec 2015 to Sunday 3 Jan 2016: The latest indications are that changeable conditions are expected at first. There may be some drier spells initially, however showers or longer spells of rain are likely to affect most places at times as Atlantic weather systems move across from the west accompanied by strong winds. Later in the month there is an indication of some more in the way of drier and perhaps colder spells, although there still remains some uncertainty with spells of rain still likely. A large variation in temperatures, mild conditions at times associated with frontal systems with colder interludes between. Updated at: 1226 on Sat 05 Dec 2015 http://www.metoffice.gov.uk/public/weather/forecast
  18. UK Outlook for Thursday 10 Dec 2015 to Saturday 19 Dec 2015: A band of cloud and rain is expected to move southeast across the country on Thursday with strong winds in places. This will be followed by brighter weather and blustery showers, spreading to all parts during Friday and heralding a change to colder conditions. Showers will continue into the weekend, most frequent and heavy in the northwest with snow over high ground. It will be cold overnight in sheltered spots with a frost possible. Strong winds at first will tend to ease through the weekend, with a drier although still rather cold interlude possible at the start of next week. Thereafter, it is likely to turn changeable with rain bands spreading across the UK bringing milder conditions and strong winds at times, but still interspersed will colder, showery spells http://www.metoffice.gov.uk/public/weather/forecast
  19. UK Outlook for Wednesday 9 Dec 2015 to Friday 18 Dec 2015: After a largely settled day on Wednesday, with local frost overnight, changeable conditions are expected to develop, as areas of low pressure move in from the Atlantic. These will bring showers or longer spells of rain, locally heavy across most areas. Across northern parts there will also be some sleet or snow at times mainly across high ground. Strong winds are also likely, with a risk of severe gales in particularly exposed northern areas. Between these weather systems some drier, brighter periods with lighter winds will develop as well, the best of these in the south. After a chilly start, temperatures will vary from day to day with milder conditions generally accompanying the wet and windy weather. Overnight frosts are likely in the settled and clear weather. http://www.metoffice.gov.uk/public/weather/forecast
  20. UK Outlook for Saturday 19 Dec 2015 to Saturday 2 Jan 2016: The latest indications are that changeable conditions are expected at first. Wet and windy weather will be interspersed with settled interludes bringing drier conditions. Showers or longer spells of rain will affect most parts at times as Atlantic weather systems move across from the west, giving perhaps wetter than average conditions in the west. Later in the month there may be more in the way of drier and perhaps colder weather, although there still remains some uncertainty. A large variation in temperatures, mild conditions at times associated with frontal systems with colder interludes between.
