Can we stick to discussing the models and not the MetOffice forecast. There is another thread elsewhere for that purpose: Thanks

Are you sure John? I was always under the impression it was 0900-0900 UTC, which in British summer time is an hour later? If it transferred when the clocks do then you'd essentially lose an hour in spring and gain one in Autumn?

The official method is 09:00 to 09:00 GMT (or 10:00 to 10:00 BST), with the maximum temperature in that time period being for the previous day (so a max temp in that 24 hours on Monday at 7am would go down as Sunday's maximum) and then the minimum as the following day (a min temp in that 24 hours at 11am on Monday would be Tuesday's value). For rainfall, all that falls between 09:00 and 09:00 GMT is for the previous day (so if 5mm of rain falls on Monday at 6am that will be included in Sunday's figure). Personally I prefer 00:00 to 00:00 (especially with an AWS like a Davis VP2) but keep up two records using both methods these days.

Slightly milder and wetter than average: 4.9C and 120mm

Rubbish as expected here again, just heavy rain throughout. A couple of weeks to go and it'll be 5 years since we had any measurable snow in the winter months (Dec, Jan and Feb). Surely our luck has to change at some point.

It has been a rather poor spell here with mins of -0.9C, -0.9C, -1.0C and finally -1.3C this morning. We were too far north on Sunday for the snow, too far south for the clear skies and too close to the coast meaning it was always windy. Pretty frustrating!

Hedon, East Yorkshire. November 2017 Warmest Max: 15.1°C (22nd) Coldest Max: 2.2°C (30th) Warmest Min: 12.6°C (22nd) Coldest Min: -0.2°C (6th) Average Max: 9.6°C (-0.2°C) Average Min: 4.3°C (-0.2°C) Overall Average: 7.0°C (-0.2°C) Rain: 62.6mm (101%) Wettest Day: 17.6mm (4th) Sunshine: 104 hours (153%) Air Frosts: 1 Sleet/Snow Falling: 2 days Snow lying at 0900: 1 days Dry Days: 5 Wet Days: 25 Days With Rain >1.0mm: 11 Days With Rain >10mm: 2 Thunder Days: 0 Days With Fog: 0 High Gust: 40mph (23rd) Close to average temperatures and rainfall, but exceptionally sunny. It was the sunniest November since 2006, finishing on 12 hours more than October and only 21 hours less than September. The air frost on the 6th was the earliest of the season since 2008. The 1cm of snow on the 30th was actually the first measurable snow since January 2013. The wind gust of 40mph on the 23rd was the highest of 2017 so far. Autumn as a whole was close to average on all three measures, with mean temperatures 0.4°C above normal, rainfall 91% of normal and sunshine 100% of normal.

Indeed. We managed a cover of around 1cm in the end. It doesn't sound much, but its the most since January 2013 here. It has mostly remained intact aswell, due to a max temp of just 1.7C. That's actually the lowest November maximum since 1993. A short sharp cold snap, but actually rather impressive for this neck of the woods so early!

Not too far from average for both: 4.4C and 101.6mm

This morning: Currently just 0.4C with a decent cover. First measurable lying snow since January 2013, its been a long wait!

Partly cloudy with sunny spells and snow showers. Theres also the first snow cover at 0900 of the season, albeit just! Currently 0.4C which is the min so far.

The heavy showers we've had for most of the night have now turned to sleet. The 850hPa temps are only around -4C right now, so that bodes well for tonight and tomorrow when they should dip to -7C or -8C. There should at least be some falling snow to low levels. Its pretty marginal though so wouldnt be too surprised if its not quite cold enough. Fingers crossed.

Its certainly mild out there tonight though! It's currently 14.3C here at nearly 10pm in the second half of November. Shades of 2015 there. Fortunately this should be the last time it gets anywhere near that for quite some time.

Overcast but dry with occasional bright spells. It was exceptionally mild with a max temp of 15.1C, a date record for the 22nd. The min last night of 12.6C was actually the third highest in November since 1980. Currently very mild at 14.3C and 77% humidity with a strengthening southerly wind gusting to 35mph so far.

Yes, I've noticed a slow deterioration aswell recently. The latest annoyance is the inability to switch from fahrenheit to celcius on their main PWS page. The option to change it is there, but it doesn't work most of the time. Highly irritating.

Hedon, East Yorkshire. October 2017 Warmest Max: 21.5°C (14th) Coldest Max: 9.9°C (30th) Warmest Min: 15.2°C (14th) Coldest Min: 4.1°C (30th) Average Max: 15.8°C (+1.8°C) Average Min: 9.9°C (+2.2°C) Overall Average: 12.8°C (+2.0°C) Rain: 28.0mm (47%) Wettest Day: 6.2mm (24th) Sunshine: 92 hours (85%) Air Frosts: 0 Sleet/Snow Falling: 0 days Snow lying at 0900: 0 days Dry Days: 13 Wet Days: 18 Days With Rain >1.0mm: 9 Days With Rain >10mm: 0 Thunder Days: 0 Days With Fog: 0 High Gust: 35mph (17th) Warmest since 2006 and driest since 2007. Max and min on 14th were the highest since 2011. 20.8°C on the 16th was the latest date to reach 20°C on record.

We had our first air frost of the season this morning with a min temp of -0.2C. Ill have to check later, but its probably the earliest first frost since 2008.

Living somewhere that always benefited from northerlies it has definitely been a major issue in recent years. The polar air is slightly warmer, travelling over a longer sea track due to a retreated ice edge and being modified by SSTs much warmer than normal on its way here. Its a triple whammy, assuming the jet relents long enough to allow a northerly in the first place!

Slightly milder than average: 7.6C

We've had 59 hours so far this month. Its marginally below average, but 2005 managed just 69hrs all month. 2001, 2005 and 2006 were also duller than average, so it seems dull weather goes with a warm October in a lot of cases here at least.

Mostly cloudy with a light rain shower this morning before it turned very dark with the sun becoming red due to the Saharan dust in the atmosphere. The cold front then passed over late-afternoon leaving sunny spells and an increasing wind. Despite the lack of sunshine it was exceptionally warm with a max of 20.8C, a date record and the latest date ever to reach 20C at this site since 1980. Max Temp: 20.8C Min Temp: 11.2C Mean Wind: 15mph S Max Gust: 28mph Rainfall: Trace Sunshine: 1.1hrs Currently mostly cloudy with a moderate SSE wind. Temp is 14.8C and 64% humidity - lower than for quite some time.

Exceptionally mild overnight with a min temp of 15.9C, the warmest since 1st October 1985 at this site. Today is also a date record, with a max so far of 20.6C and the 2nd latest date in the year to reach 20C (15th October 1995 reached 20.2C). Currently 20.5C and 73% humidity with long spells of sunshine.

Mostly cloudy with sunny spells and the occasional very light shower. Exceptionally warm for so late in the month, with a max temp of 21.1C, making it the 10th warmest October max here since 1980. The 15th is the latest date in the year I've seen 20C so Monday certainly looks like it could break that.

Its not only that, but that cold air that has to take a longer track over warmer seas is also warmer to start with. Take a look at 2016 above 80N, temps are some 10C above normal in winter on average: Compare to 1963: Its some 20C cooler during he first three months of the year. If the source of the air is 20C warmer, going across SSTs some 5C warmer and travelling across 500-1000 miles more of that sea, then its no surprise how things have changed. More energy in the system means a stronger jet stream (high pressure topples quicker) and more shortwaves. Its like the perfect storm of factors going against us. Time will tell if this is permanent though, as even 2010 was much more favourable:

Slightly milder than average: 11.4C
