THE DRY AIR IN THE LOW LEVELS WAS EVIDENT ON THIS EVENINGS DVN SOUNDING...WITH STILL NOTEWORTHY T/TD SPREAD BELOW 710 MB. IN THE PAST HOUR THOUGH...MULTIPLE SOUTHEAST IA SITES HAVE BEGUN REPORTING SNOW AS MORE FORCING LIKELY AIDS IN DEEPER MOISTENING OF THE COLUMN. EVEN CEDAR RAPIDS HAS SEEN SNOW...WHICH IS BASICALLY DUE WEST OF CHICAGO /IN OTHER WORDS...SUPPORT FOR LIGHT SNOW HAS REACHED THIS FAR NORTH/.

THIS IS IN PLACE WITH SYNOPTIC FORCING...AND MESOSCALE MOISTURE CONVERGENCE AT 280-285K AND MID-LEVEL FRONTOGENESIS ON THE 09.00 NAM. THESE FEATURES ARE SOMEWHAT TRANSIENT THOUGH...AND THE SHORT-LIVED NATURE LIKELY IS ONLY TO RESULT IN A HALF AN INCH AT THE MOST. THIS IN LINE WITH THE NAM AND GFS COBB DATA FOR NEARBY LAFAYETTE. ONE TRICKY ASPECT IS FURTHER NORTH...WHERE THE HRRR HAS CONTINUOUSLY TRIED TO SHOW SNOW BETWEEN MIDNIGHT AND 3 AM ACROSS THE CENTRAL AND SOUTHERN PORTIONS OF THE CHICAGO METRO AREA. THIS IS IN TANDEM WITH WHEN THE UPPER TROUGH/POTENTIAL VORTICITY ANOMALY COMES ACROSS. HAVING ALREADY SEEN SNOW THIS FAR NORTH OUT TO OUR WEST...CANNOT RULE OUT SNOW YET IN CHICAGO.

wisconsinwx Posted December 9, 2011 Share Posted December 9, 2011 The narrow strip of the heaviest snow noted here. This is reminding me of this summer already. Screwed on all sides at one time or another, yet very rarely included. Link to comment Share on other sites More sharing options...
Thunder Road Posted December 9, 2011 Share Posted December 9, 2011 I see others showing the RR. The latest HRRR has a small area of 2-3" totals on the IN/IL border a few counties south of the lake. Interesting picture from KILX though. Look at how there's a "hole" around the radar, signifying that the snow is having trouble making it all the way down. You can trace the edge of the snow area and look at the beam elevation agl and get a rough estimate of how far down the snow is penetrating.

Chicago WX Posted December 9, 2011 Share Posted December 9, 2011 This is reminding me of this summer already. Screwed on all sides at one time or another, yet very rarely included.

cyclone77 Posted December 9, 2011 Share Posted December 9, 2011 Some very light snow falling the last hour or so. Just starting to see it whiten up out there a bit. Looks like the measureless beginning of the season is over. Time to pop some champagne lol. Link to comment Share on other sites More sharing options...

cyclone77 Posted December 9, 2011 Share Posted December 9, 2011 Looks like a tenth or two out there now. First time I've seen the landscape have that white look to it since last Feb. Even though the next 8-12 days look uneventful, this is actually pretty uplifting. Link to comment Share on other sites More sharing options...

Already a dusting here, first sticking snow of the winter. it will be a shame if ORD misses the record because of a tenth or two. if the late week system is indeed all rain, we could smash the record and make it into christmas week without any measurable snowfall officially.
