MKE morning AFD..

WEDNESDAY AND THURSDAY - CONFIDENCE...LOW TO MEDIUM

MAIN CONCERN WILL BE PRECIP TYPE AND SNOW AMOUNTS ASSOCIATED WITH

APPROACHING SOUTHERN STREAM SHORTWAVE. MODELS NOT IN TOTAL AGREEMENT

YET ON PRECIP AMOUNTS AND THERMAL PROFILE. GFS BRINGS A WEAKENED

AREA OF QPF ACROSS ON WEDNESDAY NIGHT WITH THE MAIN PRECIP CORRIDOR

MUCH FURTHER SOUTH CLOSER TO THE 850 BAROCLINIC RIBBON AND UPPER

JET CORE. NAM MUCH THE SAME. MEANWHILE THE GEMNH AND ECMWF ARE

SHOWING A MORE IMPRESSIVE NORTHWARD DEVELOPMENT OF A SURFACE LOW

INTO CENTRAL AND EASTERN ILLINOIS. THE ECMWF SURFACE TRACK IS PRETTY

PRIME LOOKING WITH A QUICKER CHANGEOVER IN THE FAR SOUTHEAST. THE

GEMNH TRACK IS INTO EXTREME NE IL WHICH FAVORS THE NW CWA FOR THE

STEADIER SNOW BAND WITH A SLOWER CHANGEOVER IN THE SOUTHEAST. THE

00Z ECMWF HAS MAINTAINED THE FAVORABLE LOW TRACK WITH SRN WI MORE IN

LINE FOR A DECENT SNOWFALL. THE ECMWF HAS BEEN CONSISTENT WITH THIS

FAVORABLE TRACK AND MAINTAINING A COLDER PROFILE. GIVEN THIS SCENARIO

THERE WOULD NOT BE AS MUCH WARM AIR TO OVERCOME. THERMAL PROFILE IS

QUITE WORRISOME. IF ECMWF IS DEAD ON WITH TRACK AND

PROFILE...THERE/S POTENTIALLY ENOUGH LIQUID TO WARRANT AN EVENTUAL

WATCH/WARNING SCENARIO IN SRN WI...ANY OTHER SOLUTION AND HEADLINE

CONFIDENCE BECOMES MUDDIED.

MKE morning AFD..

Watching the shorter range hi-res models like the NMM and ARW are going to be pivotal. If they pick up a stronger baroclinic zone with a decent colder profile, then there might be something to that Euro solution. When the Euro's on its own within 60 hours, I'm just not sure I feel very confident in it.

which is why I lol'd @ MKE, taking the entire model spread under 38 hours out, and you get less than an inch for MKE. Non-Event.

Not a good sign when a model is by itself but I'd probably rather have the Euro by itself than anything else. I've seen it win in some of those situations...conversely I've also seen it fail.

The model spread you posted was just ensemble WRF style models, no ECMWF or GFS. 12z GFS improved, whatever the 12z ECMWF does is key. If it continues to be persistent and the GFS is trending towards it, that's a strong signal that this could be an event.

the GFS didn't trend towards crap, this is a non-event that might drop 2 sloppy inches in a think stripe at best. The subtitle of first legit widespread snow of the season is ridiculous.

Hey, I'll take anything I can get. If I get 2" of heavy wet snow, I'll take it and run this winter. Gets us close if not right to the 20" mark if that happens.

lol...I got a little excited earlier in the week when local meteorologists said "we could get up to 4 inches" for the Thursday event...I thought that sounded like a lot of snow....for this winter, it is! Besides 1 surprise lake effect event, I have yet to get more than 3 inches (if that) from any "storm" this winter.
