NWS STORM PREDICTION CENTER NORMAN OK
1117 AM CST THU DEC 25 2025
VALID 261200Z - 271200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE NOT EXPECTED ACROSS THE CONTINENTAL U.S. FRIDAY OR
FRIDAY NIGHT.
..SYNOPSIS
A PERSISTENT MID-LEVEL RIDGE WILL BEGIN TO WEAKEN AS IT MOVES ACROSS
THE CENTRAL U.S. FRIDAY. AT THE SAME TIME, A BROAD TROUGH OVER THE
WEST COAST WILL FINALLY MOVE ONSHORE AND INTO THE WESTERN STATES.
ISOLATED THUNDERSTORMS WILL BE POSSIBLE DURING THE DAY ACROSS
COASTAL CALIFORNIA EASTWARD INTO THE GREAT BASIN/INTERMOUNTAIN WEST,
AS MOISTURE ASSOCIATED WITH THE TROUGH STREAMS INLAND. WEAK BUOYANCY
AND ONLY MINIMAL SURFACE HEATING FROM REMNANT CLOUD COVER AND
MULTIPLE DAYS OF PRECIPITATION SHOULD GREATLY LIMIT SEVERE
POTENTIAL.
..EASTERN GREAT LAKES TO THE MID ATLANTIC
A SECONDARY TROUGH ON THE EASTERN PERIPHERY OF THE RIDGE WILL
INTENSIFY AS IT MOVES OUT OF THE GREAT LAKES AND INTO THE
NORTHEASTERN US LATE FRIDAY INTO EARLY SATURDAY. A MODEST SURFACE
LOW AND LOW-LEVEL WARM ADVECTION WILL ALLOW FOR WEAK ELEVATED
DESTABILIZATION AND ISOLATED STORMS OVER PARTS OF EASTERN MI AND OH,
INTO THE CENTRAL APPALACHIANS FRIDAY EVENING. BUOYANCY WILL BECOME
INCREASINGLY SCANT FARTHER EAST INTO THE MID ATLANTIC. WHILE A FEW
STORMS REMAIN POSSIBLE INTO EARLY SATURDAY, PEAK MUCAPE BELOW 500
J/KG SUGGESTS SEVERE POTENTIAL IS VERY LOW.
