Iastfan112 Posted December 3, 2011 Share Posted December 3, 2011 Moderate to occasionally heavy snow here north of Fort Dodge. Roads have really deteriorated in the past hour in Fort Dodge itself(was working at Kum and Go, pita how often I had to shovel and sand at the end of my shift). Nice flake size as well. About 2.5 fallen thus far. Link to comment Share on other sites More sharing options...

About 2.5 fallen thus far. I have family who live up near Spencer, nw of you and 4" has fallen so far and still coming down hard. Not a flake here as it's a miss to my se about 60 miles.

Iastfan112 Posted December 4, 2011 Share Posted December 4, 2011 Been getting "dry slotted" for awhile now but still have roughly 5 inches on the ground so I'm not complaining. Looking at the radar I'm guessing someplace around Storm Lake and Pocahontas will get some very nice totals. Link to comment Share on other sites More sharing options...
baroclinic_instability Posted December 4, 2011 Share Posted December 4, 2011 Been getting "dry slotted" for awhile now but still have roughly 5 inches on the ground so I'm not complaining. Looking at the radar I'm guessing someplace around Storm Lake and Pocahontas will get some very nice totals. Not bad. Twin Cities did ok too, seems like most areas saw anywhere from 2-4". This storm was a headache to track, I am kind of glad it is over with. We had crazy gradients as expected with 1" here at LBF and up to 12" 30 miles southeast.

Srain Posted December 4, 2011 Author Share Posted December 4, 2011 Look for some changes ahead as the guidance is not handling this situation too well in the Texas Panhandle: AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LUBBOCK TX 942 PM CST SAT DEC 3 2011 .UPDATE... HAVE MADE FAIRLY SIGNIFICANT CHANGES TO THE CURRENT FORECAST REGARDING THE OVERNIGHT AND DAYTIME HOURS SUNDAY. IF CURRENT NWP TRENDS CONTINUE...ADDITIONAL CHANGES WILL BE REQUIRED WITH THE OVERNIGHT/EARLY MORNING FORECAST PACKAGE. SOLUTIONS APPEAR TO BE UNDER ESTIMATING THE DEPTH OF THE CURRENT UA LOW OVER ARIZONA. ADDITIONALLY...MODELS ARE STRUGGLING TO RESOLVE WEAK FORCING/ASCENT NOW SUPPORTING CONVECTIVE SHOWERS OVER THE TRANS PECOS/PERMIAN BASIN. THIS ACTIVITY APPEARS TO BE ASSOCIATED WITH THE REAR/ENTRANCE REGION OF AN UPPER AIR JET... AND MAY BE AIDED BY WEAK ISENTROPIC UPGLIDE. EVEN SO...ALL MODELS NOW GENERATE LIGHT QPF OVER THE SOUTH PLAINS BY SUNDAY MORNING. THIS SEEMS REASONABLE GIVEN THAT ANY WEAK FORCING ASSOCIATED WITH THE REAR OF THE UA JET SHOULD TRANSLATE NORTH AS IT PROPAGATES SLOWLY NORTHEASTWARD OVER OKLAHOMA/KANSAS THROUGH MIDDAY SUNDAY. THUS AT LEAST A SLIGHT AND/OR LOW CHANCE /20-30 PERCENT/ OF PRECIPITATION IS WARRANTED LATE TONIGHT AND TOMORROW. FURTHER... DRAMATIC CHANGES IN 00Z MOS GUIDANCE SUGGEST AN INCREASED LIKELIHOOD THAT THE DAYTIME PRECIPITATION MAY BE WINTRY...WITH MET MOS TEMPERATURE MAXIMA NOW IN THE 30S AND POPS UPWARDS OF 70 PERCENT...AND SREF MEASURABLE SNOWFALL PROBABILITIES UPWARDS OF 30-40 PERCENT OVER PART OF THE AREA BEFORE 00Z. FOR NOW...HAVE LOWERED AFTERNOON HIGHS AND INTRODUCED POPS...AND WILL LET THE NEXT SHIFT FURTHER EVALUATE AS THESE NWP TRENDS CONTINUE TO EMERGE.
