Model output discussion - The run up to Christmas
ALL ABOARD replied to Met4Cast's topic in Forecast Model Discussion
Yes further west on the icon. Not so good for the initial plunge. What it does do though as is evident on the icon, is allow the Atlantic ridge to remain in situ and leave small heights further north that would likely allow further sliding scenarios. All in all a great chart for December. -

Model output discussion - The run up to Christmas
ALL ABOARD replied to Met4Cast's topic in Forecast Model Discussion
Well personally for me it's nice to be looking for chances of snow and a downward temperature than checking where is going to flood next or wondering what temperature record were going break. Yes the Greenland ridge is now toppling but the stubbornness of it to topple over us is completely different from previous years. -

No I understand what your saying. But the computer programming is run backwards in a complex manor. There was nobody I can assure you sitting around in the 1600s knowing what a minus 5 isotherm was. -

I'd dispute this. I'm pretty sure the archive charts are run from a modern computer backwards. Otherwise how would we have charts dating back to the 1600's. -

Kudos to the GFS btw. It picked this pattern up and has run with it with only slight variants over the last few days. Considering we see it run 4 times a day and usually a custom to large swings it's been pretty remarkable. -

Model output discussion - Closing in on Christmas
ALL ABOARD replied to Paul's topic in Forecast Model Discussion
Yes great start to the afternoon. As others have alluded too an Atlantic ridge that nudges into Greenland is very rare. Expecially so at this time of year as the jet is usually at its strongest and any riding is quickly flatterned. Usually to get a decent Greenland high, we see low pressure moving north in the Atlantic which produces WAA(warm air advection), this one however is slightly different. So fingers crossed, as 100 miles in this scenario is the difference between a winter wonderland or hiring a boat. -

All theoretical of course but this run may end with a major snow storm. Low skirting around the fading Atlantic ridge into the cold air situated over the UK. All in all a good run for those of a wintery disposition. -

ALL ABOARD replied to Paul's topic in Forecast Model Discussion
Much better run than the 12z obviously it has a different setup but baby steps. All hypothetical past 240 but could we see a renewed Greenland push on this run? -

If you mean topple into a scandi high then yeah.. -
Model output discussion - Closing in on Christmas
ALL ABOARD replied to Paul's topic in Forecast Model Discussion
Scandi high incoming.. If the vortex sets up there as others have alluded too I can't see it returning to Greenland any time soon. Another positive day in the hunt for cold gains traction. -

You know as well as I do the strat dosent tend to flip flop like operational runs. The slight warming that will get underway from 144 has been counted down all the way from 384 on the new GFS.- 1,801 replies
