Iastfan112 Posted December 20, 2012 Share Posted December 20, 2012 I'm going with ~7 inches here(Fort Dodge,IA), lots of drifting so it's hard to be completely certain. Accumulating snowfall looks to be over. Link to comment Share on other sites More sharing options...

Actually glad to see a nice soaker at least, should squelch any thoughts of drought. As we were running several inches under in the rainfall dept.

cyclone77 Posted December 20, 2012 Share Posted December 20, 2012 0.77" of rain so far. Still pouring. Could end up with over an inch of rain before we switch to blizzard around noon. RAP still stalls the heavy defo over us for almost 6hrs. Link to comment Share on other sites More sharing options...
Chicago WX Posted December 20, 2012 Share Posted December 20, 2012 similar deal here Yeah, but you changeover two hours earlier than here. There's one panel where LAF is almost surrounded on all sides by snow...it's quite comical. But just short range model fodder. Just in case, good thing though I stuck to my guns on a T for MBY.

OceanStWx Posted December 20, 2012 Share Posted December 20, 2012 Here's your support for the SPC MCD. +3 PWAT anomalies, carried up and over the front by a +4 LLJ. And you have a -3 cold conveyor in the def band. There is some sting in that. Link to comment Share on other sites More sharing options...
hawkeye_wx Posted December 20, 2012 Share Posted December 20, 2012 Newest RAP is pulling the new deformation zone away from eastern Iowa faster this morning. Radar is also showing the developing precip shield shifting eastward. This is looking like a pretty big bust for CR. Link to comment Share on other sites More sharing options...
cyclone77 Posted December 20, 2012 Share Posted December 20, 2012 The morning AFD from DVN is pretty intense. THE GRADIENT OF AROUND 30 MB OVER IOWA TODAY SHOULD BE MORE THAN ENOUGH FOR VERY HIGH WINDS SUSTAINED AROUND 40 MPH...GUSTING TO 50 - 60 MPH THROUGH THIS EVENING. TREE DAMAGE AND POWER-LINE DAMAGE CERTAINLY APPEARS LIKELY DUE TO WET SNOW ACCUMULATION ON THEM STRESSED FARTHER BY HIGH WINDS. VISIBILITIES SHOULD BE SUB 1/4 IN OPEN AREAS OVER MOST THE CWA IN HEAVY SNOW TODAY. ...ONCE IT BEGINS... IT APPEARS THE BURLINGTON THROUGH QUAD CITIES TO FREEPORT COUNTIES WILL NOT CHANGE TIL 9 AM TO 11 AM...BUT ONCE IT DOES... A HIGH IMPACT EVENT WILL UNFOLD. RATES OF 1 TO 2 INCHES PER HOUR SHOULD ALLOW FOR A QUICK 4 TO 8 INCHES OF SNOW ALONG THE MISSISSIPPI RIVER IN SOUTHEAST IOWA NORTHEAST TO AROUND FREEPORT. HEAVY QPF IN MODELS IS CONCERNING FOR MORE SNOW...AND WILL BE WATCHED CLOSELY AS THINGS EVOLVE...THOUGH THE WIND IS AS MUCH AS A THREAT AS ANY WITH THIS EVENT. Well, off to work. Not sure if I'll be able to make it back home later today or not. Even if I can there might not be power. Enjoy the storm everyone. Link to comment Share on other sites More sharing options...

Radar is also showing the developing precip shield shifting eastward. This is looking like a pretty big bust for CR. I think this is a thing with the RAP...it tends to stall out defo bands in the long range and then trends towards quicker NE ejections as time moves forward.

WisTodd Posted December 20, 2012 Share Posted December 20, 2012 Snow started here at 10:15 and quickly became moderate. Measured 7.8" in 3 different locations a half hour ago. Water equivalent was .86". This is a very high confidence measurement -- the snow's very wet and the wind isn't making an impact at 10-15mph out of the NE. We've now switched over to a light mix of rain and sleet. Temp has gone up from 30.6 at 11pm to 32.8F currently. Location is 40 miles north and a few miles west of Downtown Milwaukee. 12 miles inland from the Lake MI shoreline in far south-central Sheboygan county.

Luftfeuchtigkeit Posted December 20, 2012 Share Posted December 20, 2012 I measured 7.1" just a few minutes ago on my deck.

A-L-E-K Posted December 20, 2012 Share Posted December 20, 2012 lots of convective elements feeding into the developing deformation band that will rock cycloneville...hopefully we see some crazy reports later of +SN and 70 mph gusts. dryslot now fully through chicago...hopefully some low topped convection will blow up ahead of the approaching low.
