dissident Posted April 9, 2013 Share Posted April 9, 2013 no ice in brookings, air temperature too low, we have what looks to be about 2 inches of sleet/snow here. NOAA's math adds up to 17 inches for Brookings. It's still sleeting with the snow here though, keeping down the totals.. but it shouldn't be hard to hit 3 inches by nightfall. This Afternoon Snow. High near 25. Windy, with a north northeast wind 25 to 30 mph, with gusts as high as 40 mph. Chance of precipitation is 90%. Total daytime snow accumulation of around 3 inches. Tonight Snow before 2am, then snow and sleet between 2am and 4am, then snow after 4am. Low around 25. Blustery, with a north northeast wind 20 to 25 mph, with gusts as high as 35 mph. Chance of precipitation is 100%. New snow and sleet accumulation of around 5 inches. Wednesday Snow. High near 30. Blustery, with a north northeast wind around 20 mph, with gusts as high as 30 mph. Chance of precipitation is 90%. New snow accumulation of around 3 inches. Wednesday Night Snow. Low around 24. Blustery, with a north northeast wind 15 to 20 mph, with gusts as high as 30 mph. Chance of precipitation is 90%. New snow accumulation of around 5 inches. Thursday Snow likely. Cloudy, with a high near 30. North northeast wind around 15 mph. Chance of precipitation is 70%. New snow accumulation of around an inch possible. Sioux Falls got the ice. http://www.keloland.com/newsdetail.cfm/sioux-falls-officials-activate-emergency-operations-center/?id=146343V Not that many outages reported but a lot are probably at work. SIOUX FALLS, SD - Xcel Energy says it's working as fast as possible to restore power to Sioux Falls residents in the wake of the spring ice storm. Trees and power lines have been coated with a heavy layer of ice, creating power problems. Xcel says it's restored service to about 5,000 people. But, an estimated 4,000 remain without power as of 10 a.m. Crews have been brought in from Minnesota to help get the power back on. But, they say, the damage to the system is extensive and some customers may not have power until Wednesday afternoon. Xcel says power outages have been reported in other areas as well. They're working in several South Dakota communities to get power back on. Here's some south dakota webcams http://www.safetravelusa.com/sd/ Surprisingly it looks like we have more snow/sleet accumulation than watertown, the storm's first segment has followed the GFS and GEM route and not the NAM route. More webcams that update more sporadically... Web Cams Link to comment Share on other sites More sharing options...

jcwxguy Posted April 10, 2013 Share Posted April 10, 2013 Decided to post in this thread since its technically winter weather. Just witnessed a 4.5" diameter branch snap from a tree due to weight of the ice on it! winter storm warning here for up to .50" of ice.. Link to comment Share on other sites More sharing options...
Jim Marusak Posted April 10, 2013 Share Posted April 10, 2013 it is now snowing in the north end of st paul. and looking at least the NAM from the 00z runs, and what has gone on in the last 24 hours, how can I say it, it's a highly convective mess in the cooler conveyor-belt areas.

wxman1952 Posted April 12, 2013 Share Posted April 12, 2013 Dang, what a late season storm. Just rain here in lower MI. 3.16" so far since it all started. Only a high of 37 today, but not as cold as elsewhere. I'll be anxious to ses some of the webcams on my site in the morning of upper Michigan and how much snow they get. Boy, I hope this isn't a sign of the summer ahead. lol Link to comment Share on other sites More sharing options...
mnweather Posted April 12, 2013 Share Posted April 12, 2013 ATTN WFOS...APX...MQT...GRB...DLH...ARX...MPX...ATTN RFCS...NCRFC... . EVENT...INCREASING SNOW COVERAGE AND RATES ACROSS N WI/N LOWER MI AND THE UP OF MI/FAR NE MN. . SATELLITE ANALYSIS AND TRENDS...IR ANIMATION IS BEGINNING TO SHOW WHAT APPEARS TO BE A REFORMATION OF THE COMMA HEAD NEAR THE WELL DEFINED DEFORMATION ZONE OVER N WI/THE UP OF MI/FAR NE MN. THIS IS LIKELY IN RESPONSE TO THE APPROACH OF THE PRIMARY MID/UPPER LEVEL CIRCULATION CENTER NEARLY COLLOCATED WITH THE SFC LOW, ROTATING TO THE NNE OVER N IA AS SEEN IN WATER VAPOR IMAGERY AND THE GOES RGB AIRMASS PRODUCT. WATER VAPOR IMAGERY IS ALSO PICKING UP ON ANOTHER DISTURBANCE MOVING TO THE EAST OVER S IA AND YET ANOTHER RIDING THE JET NORTHWARD FROM E MO INTO IL WHICH IS ALSO AIDING IN THE OVERALL LIFT FOR THE REGION. ANALYSIS IS INDICATING MOISTURE BEING PULLED FROM THE MAIN BAROCLINIC REGION BACK TO THE NW WHICH IS NOW EVEN VERIFIED BY THE COMPOSITE RADAR ANIMATION SHOWING THE PRECIP SHIELD MOVING/EXPANDING TO THE N AND NW ACROSS N LOWER MI/N WI AND THE UP OF MI. AT THIS TIME, REGIONAL METAR OBSERVATIONS ARE INDICATING ONLY LIGHT SNOW/MIXED PRECIP IN THIS REGION BUT WOULD EXPECT THAT TO CHANGE OVER THE NEXT COUPLE OF HOURS AND BEYOND. . SHORT TERM OUTLOOK VALID 0100-0700Z...MEDIUM CONFIDENCE FACTOR IN SHORT TERM OUTLOOK...BASED ON THE SATELLITE/RADAR TRENDS, EXPECT SNOW TO INCREASE IN COVERAGE AND INTENSITY OVER THE NEXT 6 HOURS WITH AT LEAST SOME GREATER COVERAGE OF MODERATE SNOW TO LOCALLY HEAVY SNOW OVER FAR N LOWER MI/THE UP OF MI/N WI AND POSSIBLY FAR NE MN, ROUGHLY ALIGNED WITH THE HIGH PROBABILITY OF GREATER THAN 4" IN THE DAY 1 WPC SNOW ACCUMULATION GRAPHIC. SNOW RATES SHOULD INCREASE TO AT LEAST .5"/HR TO POSSIBLY APPROACHING 1.0"/HR WITH THE POTENTIAL OF EVEN HIGHER LOCALIZED RATES DEVELOPING TOWARD THE MIDDLE TO END OF THE OUTLOOK PERIOD ONCE THE BETTER DYNAMICS/FRONTOGENETIC FORCING KICKS IN.
