A COLD FRONT WILL BE THE FOCUS FOR WIDESPREAD SHOWERS AND
THUNDERSTORMS FROM THE OHIO VALLEY INTO THE CENTRAL PLAINS ON
THURSDAY. LOCALLY HEAVY RAINFALL AND STRONG TO LOCALLY SEVERE
WEATHER IS POSSIBLE. WPC HIGHLIGHTS AREAS FROM WESTERN WEST
VIRGINIA INTO EASTERN KENTUCKY WITHIN A SLIGHT RISK OF EXCESSIVE
RAINFALL, WHERE HEAVY RAINFALL FELL OVERNIGHT AND AREAS ARE
PARTICULARLY MORE SUSCEPTIBLE. THE FRONT SINKS INTO THE SOUTHEAST
AND STALLS ON FRIDAY, WITH WIDESPREAD SHOWERS AND STORMS EXPECTED
ACROSS THE SOUTHEAST TO TENNESSEE VALLEY AND PARTS OF THE SOUTHERN
MID-ATLANTIC WITH LOCALLY HEAVY RAINFALL POSSIBLE.
A COLD FRONT DROPPING INTO THE NORTHERN TIER OF THE U.S. WILL
DRIVE SHOWERS AND THUNDERSTORMS ACROSS THE NORTHERN-CENTRAL PLAINS
AND THE UPPER MIDWEST ON FRIDAY. THE GREATEST THREAT WITH THIS
SYSTEM WILL BE SEVERE WEATHER AND THE STORM PREDICTION CENTER HAS
A SLIGHT RISK FOR SEVERE THUNDERSTORMS ALL ALONG THIS BOUNDARY AS
IT MOVES THROUGH. LOCALLY HEAVY RAINFALL IS ALSO POSSIBLE,
ESPECIALLY ACROSS PORTIONS OF NORTHERN MINNESOTA AND THE U.P. OF
MICHIGAN.
UPPER LEVEL RIDGING PARKED OVER THE SOUTH WILL CONTINUE TO BRING
WIDESPREAD HEAT THREATS TO ESPECIALLY THE SOUTHERN PLAINS TO PARTS
OF THE LOWER MISSISSIPPI VALLEY THROUGH THE PERIOD. WIDESPREAD
MAJOR TO EXTREME HEATRISK IS FORECAST ESPECIALLY ACROSS PARTS OF
TEXAS WHERE A DANGEROUS HEAT WAVE HAS BEEN RELENTLESS. THE ABOVE
COLD FRONT INTO THE SOUTHEAST ON FRIDAY MAY BRING SOME RELIEF TO
NORTHERN AREAS, BUT TEXAS HEAT WILL CONTINUE INTO THIS WEEKEND.
MONSOONAL MOISTURE AROUND THE WEST SIDE OF THIS HEAT DOME WILL
BRING A SHOWER AND STORM THREAT TO THE SOUTHWEST THROUGH THE
PERIOD AS WELL.
