I think Feb 2008 was one of the sunniest on record thanks to the exceptional anticylonic warm period mid month. Feb can be a sunny and very dry month, it is not a month renowned for stormy atlantic conditions indeed I've known many a drier settled Feb than July.

February 1998 had a dry sunny and warm spell. Do you know why that happened and what caused it? I'm interested to know.

04 Dec, Brief wet snow shower in the evening.

I will update the table for entries on the first and second after midnight. What's the verdict on Robbie Garrett's dual prediction?

You'd better be right about this mild month, PIT, or I will find a new best friend.

We had a barbeque and sat in our garden on in shorts and t shirts at the weekend following that forecast - I think London got to 20C

Back to the CET

-0.4C to the 2nd. Likely to hover close to the zero mark for a few days unless forecasts are dramatically wrong.

GFS 12z follows the theme of yesterdays CFS with what would likely be a month long cold spell. Long way to go yet but if you have guessed 4C or over, you can probably tear up your betting slip now.

-0.9C to the 3rd of February.

Another falling day today, but the next few days after that may see the figure rise, but only slightly as it stays on the cold side. Another cold blast forecast for next weekend, but very much FI at present.

Minimum today is -7.2C while maxima look like being around 0C, so a drop back to around -1.6C tomorrow is a good bet.
After that, the 12z GFS has the CET at
-1.3C to the 5th (0.0)
-0.8C to the 6th (1.3)
-0.5C to the 7th (1.3)
-0.9C to the 8th (-3.3)

Mmm I don't think maxima will be around 0c. More like 2.0c or slightly higher. Most places have got a few degrees above freezing today.

Ok, I'm was just going by the xcweather map that showed maxima at around 0C or below, could have missed the peak by a bit I suppose. A maximum of 2C would make it -1.3C tomorrow.

Going by the current models we are certainly going to have a shot at a sub-zero month, though very long way to go till then...

Something around the 1.6-1.8C mark will give us a technical below average winter by the 71-00 scale...amazing really!!

-0.9C to the 10th (-0.4)
-1.0C to the 11th (-2.0)

Certainly there is strong potential for at least the first half of the month coming in below 0 degrees.

I would have thought the start to Feb 86 was equally as cold as to the start of this month? Could winter 11/12 be a role reversal of winter 10/11 with a very cold last 4 weeks as opposed to a very cold first 4 weeks. There is a chance the winter as a whole comes out slightly below the average, despite the mild Dec and January something many people a couple of weeks ago would have said is impossible.

I do feel this month could easily beat Feb 91 for coldness but certainly not 1986 - I might be wrong..

I thought I was being way over optimistic with my punt of 0.4C but it looks a bit more attainable now given the current output, still a long way to go though.

Including this winter now, the last 4 winters have had at least one winter month starting off with a large -ve anomaly

January 2009, January 2010, December 2010 and now February 2012.

I think values this week are going to depend a lot on cloud cover.

To be fair i think the chances of getting back to average are now gone, it would take something unprecedented if the CET is near -1C to the 11th.
