This might be a little bit of a ramp but so what.
We now have reliable cold other the UK with many areas already seeing wintry showers or full on snow events (2 inches imby and even more in some other areas although starting to thaw a bit earlier). It's the third day of falling or lying snow here, with a potential 4th tomorrow and 5th on Thursday.
We have reliable time frame cold available on all models going into this weekend, and a potential snow event for the far south tomorrow. We have by far the best synoptic for a prolonged cold and snowy spell since January 2010, with the right lining of the stars I'm now confident that by the 3rd week of January we could have over a foot of snow even to low levels, and long lasting cold to keep it in place with temperatures widely below - 10 in city centres with big UHI's such as Manchester and London.
This winter will be severe, I can say this with confidence because one of the things that links every severe cold spell in British history is below average flights, naturally with Covid the number of flights has been far below average - indicating that January and February will be severely cold and snowy. Let's enjoy this historic period of weather.
