Flipped through the CIPS analogs earlier and it doesn't seem like any had a pressure gradient quite like what we should have with this storm.  This is gonna be good. 

 

Even in areas that don't get snow/ice, heavy rain/high winds could make some weaker trees susceptible.

MKX write up and thoughts.

http://www.weather.gov/mkx/dec28_winterevent

 

The potential is increasing for winter weather to finally return to southern Wisconsin on Monday and Monday night. The medium range computer models are coming into better agreement on Low Pressure located in the southern Plains on Monday morning taking a northeast track toward and through the western Great Lakes Monday and Monday night.  

Warmer air flowing northward ahead of this system will result in a wintery, messy mix of precipitation types across southern Wisconsin, including freezing rain and icing, as well as sleet and snow.  The mixture may change to all snow before ending later Monday night.

Guess they're thinking an eastward track...?

The February 24, 2007 storm that Natester mentioned earlier...that had a nice pressure gradient but the high pressure was centered a bit farther north so the gradient looks even better this time.

 

Got dry slotted early in that storm. About 4" with some IP mixed in. On the 25th it rained before another 1" of snow fell.

 

I think Milwaukee did really good though.

Actually thundersnow was reported at MKX early that morning.

The February 24, 2007 storm was also very strong and dynamic. Certainly do not want to go through another storm like that again. :axe:

DVN AFD:

 

WITH MODELS IN LINE WITH EACH OTHER TODAY...I AM CONCERNED THEY ARE  
NOT DONE SHIFTING NORTHWEST IN THIS NEGATIVELY TILTED LOW SCENARIO.  
IN FACT...LACKING SNOW COVER I AM CONCERNED IT MAY CONTINUE TO LIFT  
NORTHWEST IN FUTURE RUNS. THUS I SEE SOME POTENTIAL FOR SHORT LIVED  
BUT POSSIBLY HIGH IMPACT SNOW/SLEET/FREEZING RAIN AS THE BAND LIFTS  
THROUGH OUR CWA...EVENTUALLY MERGING WITH AN ALL SNOW DEFORMATION  
ZONE OVER IOWA AND POSSIBLY NORTHEAST IOWA. WINDS WILL BE VERY  
STRONG IN THE GRADIENT BETWEEN COLD 1040MB HIGH PRESSURE TO OUR  
NORTH AND WHAT COULD BE A SUB 995MB LOW COMING UP THROUGH MISSOURI.  
THAT NORTHEAST TO EAST NORTHEAST WIND IS POSSIBLY GOING TO BLOW AT  
30 MPH SUSTAINED...GUSTING TO AROUND 40 TO 45 MPH. THUS...THE WINTRY  
PCPN SUNDAY NIGHT AND MONDAY ARE LIKELY TO HAVE A MAXIMIZED IMPACT  
TO TREES AND POWER LINES AS WINDS PUT ON ADDED PRESSURE.

 

Reminds me of December 1, 2007 to an extent...

Further Northwest would maximize ice for the entire subforum.

No it wouldn't. Too far northwest and any ice would be confined to IA/WI/parts of MI

 

Right. With the western solutions, more warm air gets pumped up into SE MI, NE IN and OH minimizing icing other than maybe a little with precip onset. Also, depending on temps, could be a little sleet mixing in.
