Chicago Storm Posted December 12, 2010 Author Share Posted December 12, 2010 LOT sticks with WSW, but drops totals to 3-5" north of I-80...which is likely still too high. FOR SNOWFALL AMOUNTS TODAY...HAVE BACKED OFF SLIGHTLY FROM THE PREVIOUS FORECAST AS THE SYNOPTIC SNOW BAND WILL BE QUICK MOVING. ACTUALLY AMOUNTS MAY BE A MOOT POINT ANYWAY AS STRONG WINDS WILL MAKE ACCURATE SNOWFALL MEASUREMENT DIFFICULT OR IMPOSSIBLE. FOR THE SYNOPTIC SNOW...WILL NOW GO WITH A SWATH OF 3 TO 5 INCHES GENERALLY NORTH OF INTERSTATE 80 IN ILLINOIS. SOUTH OF I-80...SNOWFALL SHOULD BE AROUND 1 TO 3 INCHES. THE BULK OF THIS SNOWFALL SHOULD BE BETWEEN 06Z THIS MORNING AND 00Z THIS EVENING. THE PERIOD OF HIGHEST SNOWFALL RATES...COMBINED WITH THE STRONGEST WINDS SHOULD BE BETWEEN 15Z AND 21Z. THIS WOULD BE THE MOST FAVORABLE TIME FOR CONDITIONS TO APPROACH BLIZZARD LEVELS. WHILE WINDS SHOULD SUBSIDE A LITTLE AFTER 21Z AND THE SYNOPTIC SNOW WILL BEGIN TO WIND DOWN...TRAVEL CONDITIONS WILL REMAIN POOR AS SUSTAINED 25-30KT WINDS WILL KEEP THE THREAT OF BLOWING AND DRIFTING SNOW. AS TEMPERATURES DROP THROUGH THE DAY...EXPECT SUB-ZERO WIND CHILLS BY LATE MORNING. Link to comment Share on other sites More sharing options...
Justin Posted December 12, 2010 Share Posted December 12, 2010 Only a dusting here so far, with a few flurries currently. North winds are just starting to pick up, and the temp shot back up to 28. The deform over eastern Iowa looks pretty meager, with just a few decent narrow bands mixed in there. We might not even get an inch here now. How much longer will the QC go without a 12" storm? It's already been over a decade. Yeah cyclone its been pretty disappointing considering the last few Winters. A lot of huge snow storms all around us but never thru the heart of the DVN area. The last big one has to be that New Years storm 1999- that was nice, nice, nice... but that looked like a downer at first but we ended up doing very well. I don't see us getting a huge one this Winter either but it's to early to say since we are only into the second week of met. Winter. But the hot spot has been MN and adjacent areas so far. That trend can't keep up the entire season. And to the other posters... no way Northern IL gets 3-5" of snow... just look to the West the band of snowing is weakening and falling apart quickly. Its going to be interesting to see parts of MO and Central/Southern IL get more snow than a lot of places further North. Wind is really, really cranking up here now...yikes.

michsnowfreak Posted December 12, 2010 Share Posted December 12, 2010 Thin coating of snow so far. DTX keeping north of Detroit in a warning still and south of Detroit in advisory, but they do mention the advisory area will have to be watched because of the snow from the secondary low (ie possibly upgrade). They also talk about possible power outages with wet snow. Link to comment Share on other sites More sharing options...

michsnowfreak Posted December 12, 2010 Share Posted December 12, 2010 Instant winter wonderland. Air is choked with big snowflakes, low visibility, everything snowcovered. Probably going to be a spectacular scene judging how the trees are getting coated already. Looked like a little more here than by the airport when I was out. DTW had 0.4" thru 7am, here looks to be closing in on 3/4 inch already and snowing moderately. Roads covered with slushy snow. Getting VERY excited as it looks like that L progged to develop over Lk Erie and enhance qpf over eastern MI is coming to fruition! Link to comment Share on other sites More sharing options...

ams30721us Posted December 12, 2010 Share Posted December 12, 2010 Good morning all. Waking up here to about a 1/2 inch to 1 inch of snowfall so far already here at the University of Cincinnati Campus. Wind is blowing snow around to so it was kind of blinding outside. Main roads are just wet but side roads do have a dusting on them. I expect these to get waaaay more slick later today and esp. tonight. 2-4 inches is the current thinking around these parts.

What I have briefly looked at hasn't made me change my mind too much from my forecast yesterday (For Warsaw, IN). I'll go 1-3" synoptic and an additional 1-3" lake effect Monday into Monday night. So...2-6" by Monday night. Looking good northeast of here though. Link to comment Share on other sites More sharing options...
michsnowfreak Posted December 12, 2010 Share Posted December 12, 2010 Thru 8am, storm total precip imby 0.48", snowfall 0.7". VERY heavy wet slushy snow. The trees are gorgeous. This will probably be the most scenic snowfall (in terms of tree flocking) since Feb 26, 2008. Link to comment Share on other sites More sharing options...

csnavywx Posted December 12, 2010 Share Posted December 12, 2010 Amazing. A grand total of perhaps 1/2" of frozen mashed slush and powder from this storm. Am just now starting to get a bit of light snow after spending 9 hours in the dry slot. Some nice deform bands near STL, how much have they picked up so far? Edit: Wow, even Beau is getting in on the action. Talk about spreading it around. Link to comment Share on other sites More sharing options...
Indystorm Posted December 12, 2010 Share Posted December 12, 2010 Quick inch here overnight to whiten up the ground after the rain washed residual snow away yesterday. Looks like the deformation band on back side of 850 and 700 mb low is re intensifying to the west in Illinois. Looking good as that, the winds, and eventually LES move east.

After taking the elevator down and actually stepping outside we are seeing decent flakes mixed with RAIN, bank thermo 35. It's trying hard to SN or SN+ you can tell, but we're smack dab middle of the warm tounge. Link to comment Share on other sites More sharing options...
