Feb. 2-4 Potential Winter Storm


snowlover2

Recommended Posts

I only started 1 thread for a storm last winter and it ended up being the best snowfall (6") that i saw so i figured i'd start this one and hope for similar results. GFS/GGEM/Euro all show a storm with the GGEM/Euro being the strongest to this point. 0z GGEM had a strong Apps runner with a great hit for Ohio. 12z GGEM still had an Apps runner but not as strong so precip on the backside was not as strong either. 12z Euro going by the Wundermap snowfall loop was a good hit for most of Ohio except the far northwest part. Looked like a solid 3-6". Potential seems to be there just have to see if it will finally work out for us.

There are hints of some decent possible during this time. As HM mentioned, in the another thread, the models are struggling with this pattern (due to the mtn torque change I believe). Let’s hope this can turn into something more significant for the GL/MW group.

This! And the models will continue to struggle mightily per HM.

With all the media attention vis a vis Peyton and Irsay, not to mention how mild the winter has been....it would be as they say "only the colts" to have a whopper of a snowstorm. All good stuff in this guy's eyes. This morning's AFDs from IND and IWX were in opposing camps, eventhough IND mentioned phasing yesterday, they left it out today, whilst IWX mentioned models will have difficulty on this storm for the time being and they wouldn't place bets either way.....

Bring it on :snowing:

Probably a cutoff of some sort

Cutoff as in snowfall amounts. Not really as in low pressure. It might end up being a cut-off low though.

There's like a trace of snow in downtown St. Louis and 10" just west of St. Charles.

Really? No one's going to comment on the 0z Euro?

Nice system on Thursday-Friday. Looks like a blanket snow event from central IL to Chicagoland to northern IN and lower MI. Generally DTW-FWA-LAF and north gets at least *some* snow, with max amounts in the snow region topping 0.75" or so. You can all look at the Wunderground maps for yourselves.

The problem is the bl, which is torchy. No one gets below 0 C, but at least we're all below 4 C. Still though, verbatim would be mixing and crappy ratios. Hopefully Chi Storm can throw out some numbers tomorrow morning.

Yeah it would be close with the temps but decent track for LAF-FWA-DTW-YYZ. Btw the Euro brings down the Arctic afterwards.

It is nice BUT..

From GRR..

.LONG TERM...(415 AM EST SUN JAN 29 2012)

(TUESDAY NIGHT THROUGH SATURDAY)

HAVE OPTED TO FOLLOW THE GFS THROUGH THE LONG TERM. THE ECMWF SPINS

UP A SYSTEM AND PUSHES SIGNIFICANT PRECIPITATION INTO THE SOUTHERN

GREAT LAKES ON THURSDAY. THE PMDHMD DISCUSSION FROM HPC FAVORS THE

GFS AT 84 HOURS EXPLAINING THAT THE ECMWF AS AN OUTLIER. WITH THIS

IN MIND...THE GFS HAS A FAIRLY BENIGN LONG TERM PERIOD.

Not saying it wont happen but yeah it would be nice to see better model support.

Coup time for the Euro? Northern IN thinks so.

IWX:

THE ECMWF REMAINS THE MODEL OF CHOICE. HOWEVER...IT/S SOLUTIONS CONTINUE TO EXHIBIT TRACK/STRENGTH

DIFFERENCES PER THE THUR PERIOD AS THE 00Z RUN HAS RE-INTRODUCED A

POTENT SW EJECTING UPPER TROUGH. THE PRIMARY IMPETUS FOR SUCH A

RADICAL SHIFT IN RUN-RUN SOLUTIONS IS THE JUXTAPOSITION OF A LONG

LATITUDINAL JET CORE...WITH THE NOSE OF THIS JET INTERACTING WITH

THE ROCKIES. EXPECT CONTINUED FLOW ADJUSTMENT WITH POP ADJUSTMENT....

THUR STILL REMAINS QUESTIONABLE GIVEN A POTENTIAL EJECTING SW CONUS UPPER

TROUGH. WILL NOT THROW OUT THE 00Z ECMWF...WHICH REMAINS A STRONG

OUTLIER.

IND:

THE CULPRIT FOR THE HIGH QPF PROG

FROM THE 00Z EURO IS AN OUTLIER STRONG SOUTHERN UPPER TROUGH THAT

SPINS UP A DECENT SURFACE WAVE THAT LIFTS NORTHEAST ALONG THE OHIO

RIVER THURSDAY. NON OF THE OTHER MODELS INCLUDING ENSEMBLES SHOWS

THAT. SO...WITH THE EURO WAFFLING SO MUCH...ESPECIALLY DONT TRUST

ITS SOLUTION.

GRR:

ILX:

ECMWF HAS BEEN PARTICULARLY INCONSISTENT FROM

RUN-TO-RUN...SO ITS 00Z 29 JAN SOLUTION FEATURING A RATHER DEEP AREA

OF LOW PRESSURE TRACKING ACROSS ILLINOIS ALONG THE TRAILING COLD

FRONT ON THURSDAY HAS BEEN REJECTED.
