WINTER 2010/11 FORECAST TEXT POSTED AT BOTTOM OF PAGE.


A cold front will sweep across the upper Midwest today. Gusty northwest winds will follow the front as cooler air spills into the area. Temperatures will remain mild today, but cooler weather is expected overnite tonite and Thursday and Friday. Expect Isolated snowshowers far east along with the front. A return to mild fall weather is expected for the weekend.

NEXT WEEK? EXPECT A PATTERN CHANGE AS EVIDENT BY THE RECORD HIGH TEMPS IN THE SW U.S. LATE THIS WEEK. THE PATTERN WILL GO MORE LOW ZONAL AS A TRAIN OF SYSTEMS SLAM INTO THE PACIFIC NW AND TRACK SE INTO NEW MWXICO AND THE TEXAS PANHANDLE, BEFORE EJECTING NE INTO THE LOWER PLAINS. LOW PRESSURE WILL TRACK AROUND OR NEAR SRN IOWA EARLY NEXT WEEK DRAGGING SHOWERS AND STORMS ALONG WITH IT. ONCE THE LOW MOVES INTO ILL ON THE 9TH OR 10TH, COLD AIR WILL WRAP AROUND ON THE WEST SIDE AND ALLOW COLD CANADIAN AIR TO SPILL INTO THE UPPER PLAINS AND SQUEEZE OUT SNOWSHOWERS IN IT'S WAKE. MAJOR SNOW? NOT LIKELY - BUT AFTER THE 12TH, THINGS REALLY BECOME DICEY. WITH COLD AIR IN PLACE, THE GULF OF MEXICO OPENS UP FOR BUSINESS. LOW LEVEL MOISTURE WILL STREAM NORTH TO SOUTH THRU A 4 DAY PERIOD FROM THE 12TH TO THE 16TH. DEFINATELY WORTH WATCHING.
