THE NWS STORM PREDICTION CENTER IN NORMAN OK IS FORECASTING THE

KANSAS AND MISSOURI.

AN INTENSIFYING SURFACE LOW PRESSURE WILL TRACK NORTHEASTWARD ALONG
A FRONT ACROSS THE UPPER MISSISSIPPI VALLEY AND INTO ONTARIO CANADA
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 JUST AHEAD OF THE
