...SEVERE THUNDERSTORMS AND HEAVY RAIN POSSIBLE FOR THE CENTRAL
PLAINS, MIDWEST, AND OHIO VALLEY...

...GRADUALLY RISING TEMPERATURES FORECAST ACROSS THE WEST COAST
STATES...

A FRONTAL SYSTEM MAKING ITS WAY THROUGH THE MIDWEST AND PLAINS IS
EXPECTED TO CAUSE HEAVY RAINFALL AND SEVERE WEATHER OVER THE NEXT
COUPLE OF DAYS. THROUGH THURSDAY MORNING, SEVERE WEATHER IS
FORECAST ALONG A COLD FRONT FROM THE CENTRAL PLAINS NORTHEASTWARD
INTO THE MIDDLE AND UPPER MISSISSIPPI VALLEY. IN THE MISSISSIPPI
VALLEY, THE THREAT OF HEAVY RAIN AND FLASH FLOODING IS ALSO
PRESENT. SEVERE WEATHER AND HEAVY RAIN ARE POSSIBLE ONCE AGAIN ON
THURSDAY IN THE CENTRAL PLAINS, AND AS PART OF THE COLD FRONT
SINKS SLOWLY SOUTHWARD, THE OHIO VALLEY WILL BECOME ACTIVE WITH
STRONG TO SEVERE THUNDERSTORMS AS WELL. PLEASE REFER TO PRODUCTS
ISSUED BY THE STORM PREDICTION CENTER FOR FURTHER DETAILS ON THE
SEVERE WEATHER THREAT. THE GREAT LAKES AND THE NORTHEAST WILL ALSO
HAVE A CHANCE OF THUNDERSTORMS BY THURSDAY AFTERNOON AS THE
FRONTAL SYSTEM MOVES EASTWARD. ANOTHER LOW PRESSURE SYSTEM
PROGRESSING SOUTHWARD FROM CANADA WILL HELP CAUSE SHOWERS AND
THUNDERSTORMS IN THE HIGH PLAINS AND NORTHERN PLAINS.

ELSEWHERE, SCATTERED THUNDERSTORMS ARE LIKELY IN THE GULF COAST
REGION, AND WILL SPREAD INTO THE SOUTHEAST BY THURSDAY MORNING DUE
TO PLENTY OF MOISTURE AND INSTABILITY. MEANWHILE, THE WESTERN U.S.
IS EXPECTED TO BE MOSTLY DRY OVER THE NEXT FEW DAYS. IN THE WEST
COAST STATES, TEMPERATURES ARE EXPECTED TO INCREASE OVER THE NEXT
COUPLE OF DAYS. BY FRIDAY, TEMPERATURES WILL BE 10 TO 15 DEGREES
ABOVE AVERAGE IN THAT AREA. THE SOUTHWEST WILL BE A FEW DEGREES
ABOVE AVERAGE, BUT SHOULD NOT REACH THE EXTREME TEMPERATURES THAT
IT HAS RECENTLY.
