NWS WEATHER PREDICTION CENTER COLLEGE PARK MD
324 AM EDT WED MAY 21 2025
VALID 12Z WED MAY 21 2025 - 12Z FRI MAY 23 2025
...SEVERE WEATHER AND FLASH FLOODING EXPECTED OVER THE OHIO
VALLEY/MID-ATLANTIC TODAY...
...ABOVE AVERAGE TEMPERATURES ACROSS SOUTHERN TIER STATES AND
WEST; BELOW AVERAGE TEMPERATURES FROM NORTHERN PLAINS TO
NORTHEAST/MID-ATLANTIC...
SEVERE STORMS AND EXCESSIVE RAINFALL CONCERNS SHOULD DIMINISH
CONSIDERABLY ACROSS THE LOWER 48 THROUGH MID-WEEK. A PAIR OF LOW
PRESSURE SYSTEMS MOVING THROUGH THE MIDWEST AND EAST COAST WILL
CONTINUE TO FOCUS SCATTERED TO ISOLATED SHOWERS AND THUNDERSTORMS
ALONG ITS PATH. SOME OF TODAY'S STORMS COULD TURN SEVERE,
PRODUCING LARGE HAIL, STRONG WIND GUSTS AND A TORNADO OR TWO,
ACCORDING TO THE STORM PREDICTION CENTER. SPC ISSUED A SLIGHT RISK
(LEVEL 2/5) OF SEVERE THUNDERSTORMS FROM THE OZARKS TO THE
MID-SOUTH AND FAR EASTERN NORTH CAROLINA TO ACCOUNT FOR THIS
THREAT. MULTIPLE ROUNDS OF SHOWERS AND THUNDERSTORMS COULD POSE A
FLASH FLOODING THREAT TO PARTS OF THE CENTRAL APPALACHIANS,
INCLUDING THE PITTSBURGH METRO AREA TODAY. FLOOD WATCHES ARE IN
EFFECT FOR PORTIONS OF SOUTHWESTERN PENNSYLVANIA AND THE MARYLAND
PANHANDLE.
AN UPPER LOW, PARKED AND SPINNING OVER THE GREAT LAKES AND
NORTHEAST, WILL GENERATE COOLER TEMPERATURES ACROSS THE NORTHERN
PLAINS, MIDWEST, NORTHEAST AND MID-ATLANTIC FOR THE NEXT SEVERAL
DAYS. HIGH TEMPERATURES IN THE 40S, 50S AND LOW 60S WILL REPRESENT
TEMPERATURE ANOMALIES BETWEEN 20-35 DEGREES BELOW AVERAGE.
MEANWHILE, AN UPPER RIDGE IN THE WEST AND CENTRAL U.S. WILL
PRODUCE ABOVE AVERAGE TEMPERATURES ACROSS THE SOUTHERN AND WESTERN
U.S.. SOME HIGH MINIMUM TEMPERATURE RECORDS MAY BE TIED OR BROKEN
IN FLORIDA AND SOUTHERN CALIFORNIA. MODERATE TO MAJOR HEAT RISK
WILL LIKELY INCREASE OVER SOUTH TEXAS BENEATH A BUILDING UPPER
RIDGE THROUGH THE REST OF THE WEEK.
