SouthernNJ Posted June 18, 2012 Share Posted June 18, 2012 Hopefully this powerful area of winds will weaken some before reaching the Twin Cities. Would not be good to have the amount of power outages that would come with it. Link to comment Share on other sites More sharing options...

SmokeEater Posted June 18, 2012 Share Posted June 18, 2012 Part of Wisconsin being considered for upgrade to Tornado Watch. Being there is multiple areas of rotation out there, it may be coming. MESOSCALE DISCUSSION 1208 NWS STORM PREDICTION CENTER NORMAN OK 0249 PM CDT MON JUN 18 2012 AREAS AFFECTED...NERN/CNTRL WI CONCERNING...SEVERE THUNDERSTORM WATCH 406... VALID 181949Z - 182115Z THE SEVERE WEATHER THREAT FOR SEVERE THUNDERSTORM WATCH 406 CONTINUES. SUMMARY...PORTIONS OF WW 406 CENTERED OVER NERN WI ARE BEING CONSIDERED FOR REPLACEMENT WITH A TORNADO WATCH. THIS MAY BE REQUIRED IF MORE INTENSE/SUSTAINED SUPERCELLS BECOME NOTED. DISCUSSION...SEVERAL SEMI-DISCRETE CELLS WERE PREVALENT WITHIN A WSW/ENE-ORIENTED PRE-FRONTAL CONFLUENT BAND FROM 40 W CWA TO NEAR ESC. REMNANT OUTFLOW BOUNDARY/COMPOSITE WARM FRONT INTERSECTS THIS ACTIVITY FROM MARATHON TO SHEBOYGAN COUNTIES. ALTHOUGH THE HODOGRAPH IS FAIRLY STRAIGHT-LINE...STRONG LOW-LEVEL SPEED SHEAR REMAINS NEAR THIS JUXTAPOSITION /AROUND 35 KT FROM 0-1 KM IN THE GRB VWP DATA/. ADDITIONAL SHOWERS FORMING S OF THE ONGOING ACTIVITY WOULD LIKELY POSE THE GREATEST RISK FOR DEVELOPING SUSTAINED LOW-LEVEL MESOCYCLONES...WHICH MAY BE SUFFICIENT FOR A TORNADO THREAT DURING THE NEXT FEW HOURS. ..GRAMS.. 06/18/2012 Link to comment Share on other sites More sharing options...
