Compared to previous runs ridge is stronger and more amplified. Thus far energy between date line and 150 W is weaker.

Day 4

It looks like the Pivotal site might be running slow again just like last night. Well, that's gay.

LOL fantastic. Yeah it will be nice to see snow levels lowering.

Chunky like.... Oprah/Rain mixed, or Rosie O'Donnell splats on windshield? 00z GFS in 2 minutes!

Certainly some nice improvements on 18z GEFS.

Busy day. I will likely be here for 00z runs this evening though. 00z GFS in 3 hours 00z CMC in 3 hours 45 minutes 00z ECMWF in 5 hours 21 minutes

12/1/17 6z GFS 500mb Composite Analogs Day 6-10, 8-14 Very nice improvement Day 8-14 - The positive anomaly is forecast to retrograde to roughly 150 W with an incredibly amplified block anchored over south central Alaska. This would give southern Alaska very high 500mb heights. If the block were to tilt any we would see a major blast. In this configuration we'd likely see modified arctic air into eastern Washington/Columbia Basin. I would be more confident if we had a ridge over the southeast/midwest. Some cold years showing up! 12z GFS in 3 hours 31 minutes! http://www.cpc.ncep.noaa.gov/products/predictions/short_range/tools/gifs/500hgt_comp_06gfs610.gif http://www.cpc.ncep.noaa.gov/products/predictions/short_range/tools/gifs/500hgt_comp_06gfs814.gif

I only saw Mark say ridging through week 2. East winds for at least a week! 6z GFS in 45 minutes

Must have real nice tilt to it also.

Oh? Does the block retrograde, or flatten with new Aleutian block setting up 160-150 W?

6z GFS in 2 hours 24 minutes!

Day 10 http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/240/500h_anom.na.png

Yeah no lol....

Day 9 (double checks) Yep http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/216/500h_anom.na.png

Day 8 block not holding as sturdy as GFS/CMC Op http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/192/500h_anom.na.png

Lol Well ridge did get shoved inland a tad.

Wow. Yeah it is. What the heck happened there. Day 6 http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/144/500h_anom.na.png

Day 7 http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/168/500h_anom.na.png

00z CMCE Ensembles still not quite on board with GFS keeping the ridge axis 130 W to just along the Coast.

Day 6 http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/024/500h_anom.na.png

Columbia Basin cold pool looks pretty D**n cold on 00z GEFS

Day 5 http://maps1.pivotalweather.com/maps/models/ecmwf/2017120100/120/500h_anom.na.png

00z ECMWF a bit colder through day 4. Would really like to see this run feature the strong block by day 6-7 as the GFS is now consistently doing.

Nice improvements on 00z GEFS
