UKMO 12Z now favouring a more sustained 'wedgey' pattern with low number 2 and 3 going in to next week, keeping Scotland and maybe N England more locked in the cold.

I had to check and well they didn’t for 99% not during the real arrival of the beast.
28th Feb 2018 max temps and 1st March 2018 comfortably subzero… Midlands for example -3C maxes parts of Wales had -5C maxes. Maybe some forget how cold it was. Unprecedented event for time of year. The GFS is pants with cold temps in my experience particularly in deep FI although we shouldn’t ignore the increased solar input, it does take more to become noticeable cold spell, but an exceptionally cold air mass will do justice in that case probably to mid March. There still is time albeit not a lot of it, of course ideally it would be a month earlier. Adjust expectations a week of snow cover what some of us experienced in December is a very long shot.
Yep, I was in central London on 28th Feb and where I was I don't believe the temperature got above -1.5C. Pretty exceptional for C. London although I believe this was the day with the -15 uppers.

Incredible set for London, mean down to -6.7. The Op only slightly below the mean up to this point.

Right so currently -5.5C in Walthamstow, and at 3am there's many more hours of the night to go. I have only really kept track of the temperature here in recent years but surely tonight could be the coldest for over a decade?

Surely the temp drop in that short a time on that super low perturbation (P30?) would be a record? It drops like a stone

Snowly lightly in Walthamstow again. -0.5C

In Epping Forest this morning the level was widely 14-15cm in open spots. More like 12cm in Walthamstow on the roads and in front gardens etc.
February 2009 is the obvious last event I can think of which beat this snow depth for this area, although I have a question mark in head about overnight 4-5th February 2012. I remember a similar depth (before quickly thawing in the afternoon). Any locals remember any details about this one?
Temperature here currently at 12:30 is -0.6C. This lying snow is going nowhere fast.

Feel like i’ve been watching the pivot for about 5 hours and now starting to realise it’s actually pivoting around me

GFS with a slider snowstorm and the -6 and -7 uppers never go away. All routes seemingly leading to cold right now

Seems like GFS basically had it spot on in the end. (Since revising down its temps to 37/38 in the last 24 hours). Means we could be in store for a 40/ 41 tomorrow if GFS doesn't revise that down too (which it hasn't done yet).

Had all my windows and doors open until about 7am. House is now sitting pleasantly at 21.3C (and I'm in an old Georgian House with single glazing!). Keep thinking it's not as hot as I was expecting today, then I go outside and realise just how cool my house is compared to out there!
I'm jealous of 21.3C! Windows closed and it's 24C inside for me but i can't complain too much about that

Really confirms to me that most of us in this country just don't know how to deal with this kind of heat at all when I see most of the houses on my road with fully open windows with no curtains shut.

I'm looking on this website and looking at some of the readings they are quite extreme. Would anyone be able to tell me if this is a reliable source of temperature information?:
Met Office WOW - Home Page
WOW.METOFFICE.GOV.UKThe UK Met Office Weather Observation Website (WOW). WOW allows anyone to submit their own weather data, anywhere in the world.For example, 42.7c just to the south of London.
Best to filter down what is shown to 'official observations' only.-

Lost count of the number of lows now, but noticeable correction south for next Monday's low on the GFS 18z. Similar to the latest UKMO
