THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE

INTENSIFYING SURFACE LOW PRESSURE WILL TRACK NORTHEASTWARD ALONG A

TODAY THROUGH TONIGHT. THE COLD FRONT TRAILING SOUTH OF THE LOW WILL
SURGE EASTWARD ACROSS PARTS OF EASTERN IOWA AND SOUTHEASTERN
MINNESOTA AND INTO WISCONSIN THIS AFTERNOON INTO TONIGHT...AS A
STRONG UPPER-LEVEL STORM SYSTEM MOVES NORTHEASTWARD. THUNDERSTORMS
WILL DEVELOP WITHIN THE WARM AND MODERATELY HUMID AIR MASS NEAR AND
