Very encouraging charts up to the far reaches of FI at 144 with cross model agreement for an increasingly cold NW'ly flow with wintry showers in Scotland edging southwards to other northern areas by Friday. The Sub 528 line reaches the South coast on Friday in 850's lowering down to -3 to -4c. Possibly even as low as -6c if some output is to be believed.
The synoptic set up continues to be fascinating with a robust Greenland High far enough east to prevent a pesky trough pulling up mild SW'lies at that stage. This area of high pressure serves to push the jet on a more southerly path, indeed all it will take is for one of those spin off secondary lows to slide across southern England to provide some decent snow opportunities on the 'calmer evaporative' northern edge.
The bigger picture remains poised nicely with an arctic high ushering sub -25c 850Hpa's into the north of Scandinavia at 144.
Before then its looking like three days of rain and gales before we enter the next colder phase.
It dawned on me this morning that all three of the snow events I've witnessed here in SE Kent this winter have all cropped up within the 48-60 hour range. I believe as a forum we are wasting a lot of effort and energy over analysing post 144 charts that clearly have little credence given the pattern we find ourselves in this winter.
Exciting times for all.
