Tom Posted November 19, 2014 Author Report Share Posted November 19, 2014 00z Euro coming in real interesting for the Thanksgiving storm that comes off the Pacific into the Rockies out ahead of a very tight thermal boundary. This has the ingredients to become something big down the road and potentially lay down quite a bit of snow from the Plains to the Lakes and whiten the scene on Thanksgiving Day. Euro tries developing a major cutter in the extended headed towards the lower lakes. Quote Link to comment Share on other sites More sharing options...
Tom Posted November 19, 2014 Author Report Share Posted November 19, 2014 Looks like November wants to finish off with a bang. Still lots of time to figure this one out but I like the trends over the last 36 hours for this Thanksgiving storm. Cold air will be in place and the gulf wide open. Following this storm another major arctic shot heads down the eastern Rockies out of Canada to close out the month. 2 Quote Link to comment Share on other sites More sharing options...

james1976 Posted November 19, 2014 Report Share Posted November 19, 2014 So, Euro is showing 3 storms? The one late this weekend, one Thanksgiving, and one just after Thanksgiving? 1 Quote Link to comment Share on other sites More sharing options...
WildWisconsinWeather Posted November 19, 2014 Report Share Posted November 19, 2014 That's it, I'm moving to Buffalo. Don't blame you, funny thing is they don't average much more than you or I (I think in the 40s or 50 inch range) but lately with the chilly seasons, LE has been killer.

Tom Posted November 19, 2014 Author Report Share Posted November 19, 2014 Coldest average morning low of 19.4F in the lower 48 is the coldest since Nov 1976...the Historic pattern continues and the last week of this month is going to finish off with a bang and more brutal cold. GGEM/EURO are both seeing the pattern...GFS will play catch up. Quote Link to comment Share on other sites More sharing options...

Tom Posted November 19, 2014 Author Report Share Posted November 19, 2014 12z Euro run for the Thanksgiving storm potential doesn't make sense to me when you just had a powerful storm system create trough over the central CONUS and an arctic HP pushing south out of Canada.

Tom Posted November 19, 2014 Author Report Share Posted November 19, 2014 A majority of the recent runs of the GFS continue to show the Polar Vortex dislodged even farther off the Pole.

Tom Posted November 20, 2014 Author Report Share Posted November 20, 2014 The amount of warm waters hugging the Alaskan coastline and NW NAMER has been expanding in recent days. Watch for the GFS/EURO model bias in the Day 10-15 range try to bring systems closer to the coast which then creates havoc trying to develop a trough in the Central/Eastern CONUS. What does make sense is for systems to track farther off the west coast or a split flow pattern. 2 Quote Link to comment Share on other sites More sharing options...
Tom Posted November 20, 2014 Author Report Share Posted November 20, 2014 The CFSv2 has the right idea with the AO...it briefly goes positive (reloading period), then tumbles and stays negative through mid/late Dec and what appears to be for quite some time. The NAO also seems to stay relatively negative. Quote Link to comment Share on other sites More sharing options...
