brettman320 Posted February 24, 2011 Share Posted February 24, 2011 Golfball to near baseball size snowflakes...not kidding I saw that for awhile too......never seen flakes that big before.

Stevo6899 Posted February 24, 2011 Share Posted February 24, 2011 00Z HIRESW Usually when northern missouri cashes in we do well but the low stops moving north and just shoots east. Wondering why it doesn't go a bit more NW. The confluence to the north seems far enough away. Link to comment Share on other sites More sharing options...

Ajdos Posted February 24, 2011 Share Posted February 24, 2011 Picked up about 2" of snow in about an hour.. Link to comment Share on other sites More sharing options...
ksstormhunter Posted February 24, 2011 Share Posted February 24, 2011 Just pushed out 06Z SmartModel run, snowfall accumulations still looking pretty decent. Quincy with another 7.4" of snow for the next 48 hours. ORD is around 3", Danville is looking at about 8" and Lafayette around 8" or more snow. Looking at 1.0 to 1.2" snowfall rates right now.

SchaumburgStormer Posted February 24, 2011 Share Posted February 24, 2011 LOT AFD... WILL BE BOOSTING THE WINTER STORM WATCH TO A WARNING IN OUR SOUTHERN TWO ROWS OF COUNTIES FOR TONIGHT...AND STARTING A WINTER WEATHER ADVISORY FOR THE REST OF THE AREA. THE CHALLENGE WITH THIS SYSTEM HAS BEEN DETERMINING SNOWFALL AMOUNTS. MODELS HAVE BEEN JUMPING AROUND A BIT ON QPF...AND COBB SNOW RATIOS HAVE BEEN SIMILARLY UNSTEADY. LATEST ECMWF AND GFS QPF FIELDS ACTUALLY LINE UP PRETTY WELL...AND THE NAM MATCHES THE GENERAL IDEA. OUR SOUTHERN COUNTIES WHERE MODELS ARE SHOWING GREATER QPF TOTALS LIKELY WILL SEE SMALLER SNOW TO LIQUID RATIOS. FARTHER NORTH TOWARD THE WISCONSIN LINE THE MIDLEVEL FORCING IS MUCH GREATER AND THE ZONE FOR FAVORABLE SNOW GROWTH APPEARS TO BE QUITE A BIT DEEPER...BUT LIQUID TOTALS ARE MUCH LOWER. WE MAY END UP WITH TWO SEPARATE SWATHS OF HIGHER SNOWFALL AMOUNTS...ONE TO OUR SOUTH WHERE LIQUID QPF IS HIGHEST AND ONE FROM THE LASALLE AREA INTO LAKE AND COOK COUNTIES WHERE THE HIGHER QPF AMOUNTS TAP INTO THE BETTER MIDLEVEL FORCING. IN COORDINATION WITH THE DVN AND MKX OFFICES THE ADVISORY FOR KLOT WILL COVER OUR ENTIRE CWA. THERE IS THE POSSIBILITY THAT PART OF THIS AREA MAY YET NEED TO BE UPGRADED TO A WARNING...PERHAPS NOT CONTIGUOUS TO THE FIRST WARNING...WHILE PART MAY SEE SNOW TOTALS CLOSER TO 2-3 INCHES. DESPITE THE UNCERTAINTY...A REASON FOR EXTENDING IT TO THE CWA BORDERS THIS SOON...APART FROM THE WIDESPREAD 3-4 INCH AMOUNTS WE ARE ANTICIPATING...WAS TO ALLOW FLEXIBILITY AND AVOID GAPS LATER IF DVN AND MKX WISH TO ADD HEADLINES TO ADDITIONAL COUNTIES. OVERALL THIS WILL BE A QUICK SHOT OF POTENTIALLY HEAVY SNOW...WITH RATES AT TIMES GREATER THAN AN INCH PER HOUR. BY 12Z FRIDAY THINGS SHOULD START WINDING DOWN...BUT THE COMMUTE FRIDAY MORNING LIKELY WILL NOT BE EASY IN SOME AREAS...AND BLOWING SNOW MAY CAUSE ADDITIONAL PROBLEMS.

snowstormcanuck Posted February 24, 2011 Share Posted February 24, 2011 The SE nudge should have been pretty apparent because there's a meteorological rule that mby can never be anywhere near an axis of heavy snow. Link to comment Share on other sites More sharing options...
Torontonian Posted February 24, 2011 Share Posted February 24, 2011 The SE nudge should have been pretty apparent because there's a meteorological rule that mby can never be anywhere near an axis of heavy snow. EC and TWN are calling for over 6 inches total by tomorrow night. Will we get half of what they call for like last couple of supposed storms? Another wait and see. The SE movement might screw us again. Link to comment Share on other sites More sharing options...

michsnowfreak Posted February 24, 2011 Share Posted February 24, 2011 SEMI is getting hammered right now 0.8" snow here with some sleet/freezing rain (0.10" liquid). Was asleep, dont know how it fell. Snow depth a very compacted/settled 8". Amazing that widespread thundersnow was reported for the 3rd time this month!

Powerball Posted February 24, 2011 Share Posted February 24, 2011 Current 12z observations out of Texas/OK/Mexico would suggest the models were a litttle too far NW during yesterday's 18z and 21z runs. 06z GFS seems to have a good handle on things so far. Of course I could be wrong. Things should be darn near (but still just shy of) fully sampled for the 12z run. Link to comment Share on other sites More sharing options...

Of course I could be wrong. Things should be darn near (but still just shy of) fully sampled this run. Nah, you're not wrong. Even the 6z NAM was decent with the sfc low placement. I don't think initialization errors are the problem though. It's more what happens during the time the low traverses the OV. My hope is that the fairly rapid deepening (~1006 to low 990s or possibly high 980s in 30 hours) pulls the track a little further north than the 6z consensus. Past experience tells me that's probably a good bet, especially when you don't have massive arctic sfc ridging to the north. But aside from yesterday's 18z runs, there hasn't been much indication of this yet. Link to comment Share on other sites More sharing options...

Meanwhile the RUC is slowly starting to come back to earth after the 09z run. Link to comment Share on other sites More sharing options...

LizardMafia Posted February 24, 2011 Share Posted February 24, 2011 Definitely looks like LAF is in the zone for this one ... FINALLY!
