Chicago WX Posted December 20, 2010 Share Posted December 20, 2010 huh? Looks like pretty good returns over that area.

baroclinic_instability Posted December 20, 2010 Author Share Posted December 20, 2010 This frontogenesis band is becoming dominant. 18Z NAM progresses that ridiculously divergent jet over top that frontal band pretty far E for a bit too. SOme nice totals should come out of this for folks in northern ILL and S. WI. Link to comment Share on other sites More sharing options...
LizardMafia Posted December 20, 2010 Share Posted December 20, 2010 FZDZ or -ZR for the morning rush FTL. Although I think we'll manage to poke above freezing here overnight/tomorrow, although even with that, surfaces could remain icy due to the constant cold of this month. Saw that happen a couple of winters ago. Radar returns inching their way closer... Yeah, I'd like to take a pass on tomorrow mornings rush hour..

REPORTS OF 3 INCHES OF SNOW IN LASALLE COUNTY AS OF 330 PM. THIS FRONT HAS A LOT MORE LIFT THAN PREVIOUSLY THOUGHT. THIS BAND WILL MOVE INTO CHICAGO AND NORTHWEST INDIANA LATER THIS EVENING AND TONIGHT. THE LOCAL WRF MODEL SHOWS THIS INCREASE IN LIFT AND PRECIPITATION BY 06 UTC. THERE WILL AN ADJUSTMENT OF THE HIGH TEMPERATURE FOR TUESDAY. WE STILL EXPECT FREEZING DRIZZLE BUT LITTLE ICE ACCUMULATION BY 9 AM CST TUESDAY. THE TEMPERATURE ADJUSTMENT WILL BRING A LITTLE HIGHER TEMPERATURES TUESDAY MORNING. THE LOCAL WRF AND NAM MODELS WERE USED FOR THE OMEGA FIELDS MATCHING THE CURRENT SNOW. WE EXPECT PRECIPITATION ENDING TUESDAY AFTERNOON AS DRIZZLE. Link to comment Share on other sites More sharing options...

msp Posted December 20, 2010 Share Posted December 20, 2010 MPX short term forecast for MSP metro: A HEAVY SNOW BAND WILL MOVE GRADUALLY ACROSS THE TWIN CITIES METROPOLITAN AREAS...AND SURROUNDING COUNTIES...WITH SNOWFALL RATES IN EXCESS ON ONE INCH PER HOUR...POSSIBLY NEAR TWO INCHES PER HOUR. THE RATES WILL HAVE DEFINITE IMPACTS ON THE EVENING COMMUTE. LEAVE EXTRA TIME TO REACH YOUR DESTINATION. EAST WINDS WILL REMAIN AT 10 TO 15 MPH...WHICH MAY CAUSE MINOR BLOWING...BUT THE MAIN IMPACT WILL SIMPLY BE THE RATE AT WHICH THE SNOW IS FALLING. TOTAL AMOUNTS BY 800 PM OF FOUR TO SEVEN INCHES ARE EXPECTED. awful timing Link to comment Share on other sites More sharing options...

baroclinic_instability Posted December 20, 2010 Author Share Posted December 20, 2010 For the good folks over in Illinois and parts of Wisconsin, this event is a great example of NW flow with an east coast trough not negatively influencing a system as it heads east. In this case, that east coast low is acting to enhance horizontal deformation and frontogenesis, and what looked to intially be a WAA event has now turned dominant frontogenetic along the warm front. Good weather example showing confluence doesn't equal crap weather all the time. Link to comment Share on other sites More sharing options...
