234 AM EDT THU MAY 22 2025
VALID 12Z THU MAY 22 2025 - 12Z SAT MAY 24 2025
...SEVERE WEATHER POTENTIAL IN SOUTHERN PLAINS TODAY; COLD AND
RAINY IN THE NORTHEAST...
...ABOVE AVERAGE TEMPERATURES ACROSS SOUTHERN TIER STATES AND
WEST; BELOW AVERAGE TEMPERATURES FROM NORTHERN PLAINS TO
NORTHEAST/MID-ATLANTIC...
A RELATIVELY STAGNANT UPPER PATTERN WITH TROUGHING ALONG THE
COASTS AND RIDGING OVER THE CENTRAL U.S. WILL PERSIST THROUGH THE
END OF THE WEEK. LOW PRESSURE IN THE EAST WILL PRODUCE COOL AND
RAINY WEATHER FROM THE OHIO VALLEY TO THE NORTHEAST/MID-ATLANTIC.
SOME ISOLATED THUNDERSTORMS COULD PRODUCE EXCESSIVE RAINFALL OVER
PORTIONS OF SOUTHERN NEW ENGLAND TODAY BUT THAT THREAT IS
MARGINAL. A SURFACE LOW PRESSURE SYSTEM AN ATTENDANT
QUASI-STATIONARY FRONT DRAPED ACROSS NORTHERN TEXAS/OKLAHOMA WILL
BE THE FOCUS FOR POTENTIAL SEVERE STORMS THIS AFTERNOON AND
EVENING. THE STORM PREDICTION CENTER ISSUED A SLIGHT RISK (LEVEL
2/5) FOR SEVERE THUNDERSTORMS ACROSS MUCH OF THE RED RIVER VALLEY
WHERE LARGE HAIL WILL BE THE MAIN THREAT, ALONG WITH DAMAGING
WINDS. 2+ INCH DIAMETER HAIL ARE POSSIBLE ACCORDING TO SPC.
THERE'S ANOTHER SLIGHT RISK OF SEVERE THUNDERSTORMS IN NORTHEAST
COLORADO, SOUTHEAST NEBRASKA AND NORTHWEST KANSAS WHERE THE
NORTHERN EXTENSION OF THE SOUTHERN PLAINS STATIONARY FRONT AND A
DRY LINE WILL FOCUS STORMS ON FRIDAY. LARGE HAIL AND SEVERE WIND
GUSTS WILL BE THE PRIMARY THREATS ASSOCIATED WITH STORMS THAT
MATERIALIZE.
RAINFALL ASIDE, AN UPPER LOW PARKED OVER THE GREAT LAKES AND
NORTHEAST WILL FACILITATE 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.
WIDESPREAD LOW MAXIMUM TEMPERATURE RECORDS MAY BE TIED OR BROKEN
FROM THE OHIO VALLEY TO THE NORTHEAST/MID-ATLANTIC TODAY AND
FRIDAY. 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. MEANWHILE, MODERATE TO LOCALLY MAJOR HEATRISK
WILL INCREASE OVER SOUTH TEXAS BENEATH A BUILDING UPPER RIDGE
THROUGH THE REST OF THE WEEK.
