Moving Through December - Changing Patterns and Changing Diapers

OT but an interesting stat (courtesy of Joe Lundberg's blog)

There are many cities in the middle of the country that are in the midst of their longest snow drought in recorded history. For example, Des Moines, Iowa has now reached 277 consecutive days without measurable snow. In other words, not since March 4 has there been any snow fall of at least a tenth of an inch! Chicago is on the cusp of their longest such streak of 280 days that dates back to 1994, and if they get through Sunday with none, a new record will have been set there.

Those areas are about to get a snowstorm, especially west and north of Chicago.

I'm surprised Chicago's record is 1994. I guess they got shafted late in '93-'94 winter. I would have expected it to be coming off a torch winter like this year is.

Two month winter in 1993-94 at ORD, for all intents and purposes.

December: 1.2"

January: 14.2"

February: 26.2"

March: T

April: T

Last measurable was the last day of met winter that season, 0.8". Next one was December 6, 1994 (4.0").

Wouldn't that be sick with some nice snow prior to Christmas.

Yes it would be..I know its the 11-15 day gfs op and people may think were being weenies for discussing it on this particular occasion where it shows several storms, however, this depiction is entirely plausible when you compare it to the ensemble predictions in the 11-15 day... The key will continue to be how will the nao block manifest itself in the long range, along with the intricacies of these waves propagating across the country?

The 15-16th and 18th-19th potentials both show up very clearly on the 12z ensembles coming in right now by the way.

I'm keeping an eye on that 15th time too. Not that it will be big, but as some othets have said...sneaky appeal.

Pretty much have to agree with this from NCEP...

THE MEDIUM RANGE PERIOD CONTINUES TO FEATURE A STABLE AND WELL

AND POSITIVELY TILTED NOAM MEAN TROF WELL INTO NEXT WEEK. THERE

IS LOWER CONFIDENCE WITH INDIVIDUAL SHORTWAVES PROGRESSING AROUND

THE TOP OF AN AMPLIFIED ERN PACIFIC RIDGE AND CONTINUING INTO THE

PLAUSIBLE REASONS TO BUTT BANG COMMON CIVILITY OUT OF THE TYPE

OF HOLIDAY WEATHER INSTILLED IN THEIR COLLECTIVE BODY OF

EXPERIENCES AND SENTIMENTS. WITH THIS SYNOPTIC PARADIGM ONE WAY

OR THE OTHER HOWEVER PHYSICALLY NOT IDENTIFIABLE ONLY BAD UNWANTED

RESULT WILL RELENTLESSLY COME TO REALIZATION.

Yeah that one has highest appeal for northern new england and certainly bares watching down to you as well..But not so much further south. Now IF we can get the follow up close enough behind on the 18th-19th, then that potential not only has high appeal to you, but also for the northern mid-atl crew.

This would be an amazing pattern if it pans out....weak SE ridge...low heights near New foundland and good supply of arctic cold to the north.

I posted something in your thread about that. Pretty nice looking overal if it happened. That weenie lobe near Sable island would help us out with high pressure to the north.

That 97 storm would have driven me to smoke tailpipe. Thankfully the boards weren't around for that

Looks like it was warm south of the Pike. CAD signature with hp in ME but a pretty weak system in general, open in the mid-levels. That's one of the only ways the valley can avoid severe underperformance.

I agree, that could be areas south into the game too.

I think I need to get the ol SWFE t-shirt out for sunday night here...looks like a classic nailbiter. lol.

front end dumpage that only changes over after the bulk of the precip is through leaving a coating of glaze on top of the snow pack ensuring that it stays around until the permapack builds the following week and then we don't see the ground till April kinda thing?
