THE AREA OF LOW PRESSURE ACROSS CENTRAL KANSAS WILL CONTINUE TO
STRENGTHEN AND BEGIN TO MOVE TOWARD THE NORTH-NORTHEAST. ITS
ASSOCIATED FRONTAL BOUNDARIES BRING IN AN ABUNDANCE OF MOISTURE
FROM THE GULF OF MEXICO HELPING SET THE STAGE FOR CONTINUAL HEAVY
RAINFALL ACROSS THE CENTRAL U.S.. OVER 2 INCHES OF RAIN ARE
FORECAST FOR THE SOUTHERN PORTIONS OF THE UPPER GREAT LAKES. ON
THE BACKSIDE OF THIS SYSTEM...SNOW IS EXPECTED TO FALL FROM THE
CENTRAL HIGH PLAINS NORTHEASTWARD ACROSS MINNESOTA AND INTO
NORTHERN MICHIGAN WHERE 4 TO 8 INCHES ARE EXPECTED. HEAVIER
AMOUNTS ARE POSSIBLE WITHIN LARGER SNOW BANDS.    

THE NEXT STORM SUMMARY WILL BE ISSUED BY THE HYDROMETEOROLOGICAL
PREDICTION CENTER AT 1000 PM CDT THURSDAY APRIL 10. PLEASE REFER
TO YOUR LOCAL NATIONAL WEATHER SERVICE OFFICE FOR ADDITIONAL
