...SEVERE WEATHER AND ISOLATED FLASH FLOODING FOR THE GREAT
LAKES/OHIO VALLEY THIS EVENING; THREAT SHIFTS TO THE OHIO AND
MIDDLE MISSISSIPPI VALLEYS AND SOUTHERN PLAINS THURSDAY...
...WARM TO HOT TEMPERATURES ACROSS THE SOUTHERN U.S.; CHILLIER
WEATHER SPREADING SOUTHEAST FROM THE NORTHERN ROCKIES/PLAINS...
SHOWERS AND THUNDERSTORMS WILL CONTINUE TO DEVELOP INTO THE
EVENING ALONG AND AHEAD OF A COLD FRONT NOW ADVANCING EASTWARD
ACROSS LOWER MICHIGAN AND THE OHIO VALLEY. SOME OF THESE STORMS
MAY BECOME STRONG TO SEVERE, PRODUCING DAMAGING WINDS, LARGE HAIL,
AND A FEW TORNADOES. IN ADDITION TO SEVERE WEATHER, LOCALLY HEAVY
RAINFALL AND ISOLATED FLASH FLOODING ARE CONCERNS AS WELL.
LATER THIS EVENING, STORMS ARE FORECAST TO DEVELOP FROM THE
CENTRAL PLAINS INTO THE LOWER MISSOURI VALLEY. THESE STORMS TOO
MAY BECOME STRONG TO SEVERE, WITH DAMAGING HAIL EXPECTED TO BE THE
PRIMARY THREAT.
AS THE SYSTEM IN PLAINS MOVES FURTHER EAST, STORMS ARE LIKELY TO
REDEVELOP FROM THE OHIO VALLEY INTO THE SOUTHERN PLAINS ON
THURSDAY. SEVERE WEATHER WILL ONCE AGAIN BECOME A CONCERN,
ESPECIALLY ACROSS PORTIONS OF THE MID MISSISSIPPI INTO THE LOWER
OHIO VALLEYS. THE STORM PREDICTION CENTER HAS ISSUED AN ENHANCED
RISK (LEVEL 3/5) FOR PORTIONS OF THE REGION, NOTING THAT STRONG TO
SEVERE STORMS CAPABLE OF DAMAGING WINDS, AND POSSIBLY A FEW
TORNADOES, ARE LIKELY TOMORROW. WHILE WIDESPREAD HEAVY RAINS ARE
NOT EXPECTED, LOCALLY HEAVY ACCUMULATIONS RESULTING IN ISOLATED
FLASH FLOODING ARE POSSIBLE.
TEMPERATURES ACROSS THE SOUTHERN U.S. WILL REMAIN WARM THROUGH THE
PERIOD, WITH HIGHS IN THE UPPER 80S AND 90S COMMON FROM THE
SOUTHWEST TO THE SOUTHEAST OVER THE NEXT COUPLE OF DAYS. MUCH
COOLER TEMPERATURES NOW CENTERED OVER THE NORTHERN ROCKIES AND
PLAINS WILL SPREAD SOUTHEASTWARD, LOWERING TEMPERATURES ACROSS
MUCH OF THE MIDWEST AND OHIO VALLEY BY FRIDAY.
