Maybe the clusters are a day behind and haven't factored in the SSW reversal yet.... -

I'm not sure anyone can answer the question as to which way it will go.. I'd be more Inclined to think the SSW will win but who knows. I have a theory that lanina produces a warmer second period to winter but it could be the case that this only occurs when we have a strong SPV and TPV.. This year we have neither.- 1,801 replies

Winter 2020/21 chat, ramps, moans and banter
ALL ABOARD replied to Paul's topic in Spring Weather Discussion
What's perplexing this year is we've had ripe conditions for major Greenland blocking.. Yet we still can't get a decent one to stick... There's something in the background the last few years working against us.. Wether we know what it is is another matter, but at the moment there is no way of telling. -

Its quite confusing.. Because if the GFS is showing no downwelling.. What's causing the sudden change to more of a westerly influence? -

Was looking promising for a long reversal and another warming for a split.. Wonder what's driving the rapid recovery.- 1,801 replies

The cold building out east is remarkable... Hopefully the blocking falls favourable from us as you can see the decline in the ural blocking and the mega cold feeding down. The UK would be in the freezer for a substantial amount of time. ECM overall is bit mehhh if your looking for wintry nirvana.. But if your looking at it from a chart in January then it's amazing as we should be seeing a rampant jet and temps into the low teens. -

Huh? Low dropping through scandi... Jet recurving.. Definition of a 'blizzard' 'a severe snowstorm with high winds' ???

Wow what a run.... Anyone got a shovel??

So next week we have 850s at or around - 8 - 9... 60 miles of ocean at 7 degrees or so? Need roughly a 13 degree difference for Lake effect snow?
