VALLEY AND THE GREAT LAKES OVER THE NEXT FEW DAYS. MUCH OF THE

ADDITION, WEATHER PREDICTION CENTER HAS ISSUED A MARGINAL RISK FOR
EXCESSIVE RAINFALL OVER PARTS OF MID-MISSISSIPPI VALLEY AND
CENTRAL PLAINS. CHANCES FOR THUNDERSTORMS AND SHOWERS BUILD OVER
THE SOUTHWEST AND SOUTHERN PLAINS/ROCKIES AS THE FRONTAL SYSTEM
SLOWLY MOVES SOUTHWARD BY FRIDAY. WITH THE WARM MOISTURE AND
INSTABILITY, CHANCES FOR DOWNPOUR INCREASE WHICH CAN LEAD TO
LOCALIZED FLOODING OVER PARTS OF SOUTHERN PLAINS ON SATURDAY. IN
ADDITION, A OCCLUDED FRONTAL SYSTEM MOVES CLOSER INLAND FROM THE
PACIFIC, REINFORCING SHOWERS AND THUNDERSTORM ACTIVITY OVER MUCH
OF WESTERN U.S. WITH CHANCES FOR SNOW OVER HIGHER ELEVATIONS AND
MOUNTAINTOPS, ESPECIALLY OVER THE SIERRA NEVADA, BY LATE FRIDAY
INTO SATURDAY.
CHANCES FOR SHOWERS AND THUNDERSTORMS CONTINUE ACROSS FLORIDA,
ESPECIALLY OVER THE SPACE COAST SOUTHWARD INTO MIAMI, WITH THE
OVERALL PATTERN SLOWLY ERODING BY FRIDAY MORNING. THEREFORE, WPC
CONTINUES TO MAINTAIN A MARGINAL RISK FOR EXCESSIVE RAINFALL AND
FLASH FLOODING AS THE PATTERN CONTINUES TO SUPPORT 1-3 INCHES OF
RAINFALL FOR THURSDAY.
TEMPERATURES WILL CONTINUE TO TREND 5-12 DEGREES ABOVE NORMAL FOR
MUCH OF CONUS THROUGH FRIDAY, WITH THE EXCEPTION OF THE NORTHERN
PLAINS AND EAST COAST, WHERE 10-15 DEGREES BELOW NORMAL
TEMPERATURES PERSIST THROUGH THURSDAY. THE NORTHERN PLAINS AND THE
