Winter 2014-15 Med/Long Range Discussion


Chicago Storm

Recommended Posts

Looks like a tongue of upper 50/low 60 dews make it up into Indiana ahead of the bombing low.  Doesn't sound all that impressive verbatim, but that's a huge surge of moisture over what is now an arctic wasteland.  Big change on the way for folks who end up in the warm sector of this beast.

 

 

That would probably be good enough with that setup.

This first system late this weekend into early next week def has my attention from a severe weather perspective. Incredible dynamics and wind fields. Wouldn't take much instability for a substantial severe weather event. I love seeing a nice broad warm sector and a pretty large LLJ core. Like you guys have stated, most of us in this forum wouldn't see snow from this system but it could set up something interesting for the period around Thanksgiving or after as more energy reloads and a colder air mass will be further south for it to take advantage of.

snowpack, frozen ground, and 1/2 inch+ QPF for the 23/24th system for the whole subforum....should be a fun one to track and follow

 

Man if only that were a snowstorm for us. lol. that would be fun. oh wishcasting. there could be some major flooding problems with frozen ground. There could be some wrap around snows with models showing a large occlusion happening and cold air wrapping around

Thing I'd wonder about is how extensively frozen the ground is at this point.  It's been cold and will be cold for a while yet but not like we're in the middle of winter.

 

I will spare the forum the image....but 4 inch depth temps are pretty far down...surface soil temps have to be a few degrees colder even....

 

EDIT:  but a few sunny days could prolly warm things up faster since it is indeed still November, and not the heart of winter as you alluded to

Nothing frozen around here.  The snow is wet on the bottom and slowly melting from the bottom up.  My driveway starts to melt out any time the snow lets up.

11/17 weeklies

 

after current cold shot, we warm up briefly before that big storm, cool back down.   After that, from week 2 taking us up to Xmas week it's a couple of small transient hits of cold in a generally above average temp regime for most of the country,

 

disclaimer:  I am neither a warminista nor take the weeklies as gospel.

12z UKMET maintains the bomb.  We have a couple clear model camps now...the bomb/cleaner phase scenario by the UKMET/earlier ECMWF runs and the more sloppy scenario depicted by the others.

 

 

and now the 12z GGEM went back to the bomb.

 

And we're shocked? These are the two bomb-iest models in the land.
