VALID 271200Z - 281200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
ISOLATED THUNDERSTORMS ARE EXPECTED TODAY FROM THE OHIO VALLEY INTO
NORTH CAROLINA AND VIRGINIA BUT NO SEVERE THREAT IS FORECAST.
...DISCUSSION...
AN UPPER-LEVEL TROUGH WILL DIG SOUTHEASTWARD ACROSS THE EASTERN U.S.
TODAY. AT THE SURFACE, A COLD FRONT WILL ADVANCE SOUTHWARD INTO THE
SOUTHERN APPALACHIANS AND CAROLINAS. BEHIND THE FRONT, ISOLATED
THUNDERSTORM DEVELOPMENT WITH A POTENTIAL FOR A FEW STRONG GUSTS,
WILL BE POSSIBLE IN WEAK INSTABILITY THIS AFTERNOON. ELSEWHERE
ACROSS THE CONTINENTAL U.S., THUNDERSTORMS ARE NOT EXPECTED TODAY OR
TONIGHT.

NWS STORM PREDICTION CENTER NORMAN OK
1249 AM CDT FRI MAR 27 2026
VALID 281200Z - 291200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
ISOLATED THUNDERSTORMS WILL BE POSSIBLE SATURDAY AFTERNOON ACROSS
PORTIONS OF THE FLORIDA PENINSULA, BUT THE POTENTIAL FOR SEVERE
THUNDERSTORMS IS LOW.
...SYNOPSIS...
A STRONG COLD FRONT CURRENTLY PUSHING SOUTHWARD ACROSS THE PLAINS
AND OH VALLEY IS FORECAST TO REACH CENTRAL TO SOUTHERN FLORIDA BY
SATURDAY AFTERNOON. CONTINUED DISPLACEMENT FROM THE PRIMARY SYNOPTIC
LOW AND UPPER WAVE TO THE NORTHEAST WILL LEAD TO A GRADUAL ABATEMENT
OF FRONTAL ADVANCEMENT AND THE ONSET OF FRONTOLYSIS THROUGH THE DAY.
DESPITE DIMINISHING LOW-LEVEL FORCING FOR ASCENT, EVENT MODEST LIFT
WITHIN AN UNSTABLE AND WEAKLY CAPPED ENVIRONMENT WILL LIKELY SUPPORT
ISOLATED TO WIDELY SCATTERED THUNDERSTORMS BY PEAK HEATING INTO
EARLY EVENING. VERY WEAK WINDS (LESS THAN 20 KNOTS) THROUGH MUCH OF
THE COLUMN WILL LIMIT STORM ORGANIZATION AND THE POTENTIAL FOR
SEVERE CONVECTION. ELSEWHERE ACROSS THE COUNTRY, DRY AND STABLE
CONDITIONS IN THE WAKE OF THE FRONTAL PASSAGE WILL LIMIT
THUNDERSTORM POTENTIAL.

NWS STORM PREDICTION CENTER NORMAN OK
0226 AM CDT FRI MAR 27 2026
VALID 291200Z - 301200Z
...NO SEVERE THUNDERSTORM AREAS FORECAST...
...SUMMARY...
ISOLATED THUNDERSTORMS ARE POSSIBLE ACROSS THE SOUTHERN FLORIDA
PENINSULA AND PORTIONS OF SOUTHERN ARIZONA SUNDAY AFTERNOON AND
EVENING. SEVERE THUNDERSTORMS ARE NOT EXPECTED.
...SYNOPSIS...
AN UPPER-LEVEL RIDGE (CURRENTLY IN PLACE OVER THE SOUTHWEST) IS
FORECAST TO SHIFT EAST OVER THE PLAINS THROUGH THE DAY SUNDAY.
BROAD-SCALE SUBSIDENCE/HEIGHT RISES AHEAD OF THE RIDGE WILL PROMOTE
MOSTLY DRY AND STABLE CONDITIONS FOR THE CENTRAL AND EASTERN CONUS.
THUNDERSTORM POTENTIAL WILL MOST LIKELY BE RELEGATED TO THE SOUTHERN
FL PENINSULA WHERE WEAK ASCENT WITHIN A RESIDUAL FRONTAL ZONE (AIDED
BY DIURNALLY-DRIVE SEA BREEZE BOUNDARIES) MAY SUPPORT A FEW
THUNDERSTORMS WITHIN A MOIST AND WEAKLY CAPPED ENVIRONMENT. WHILE
CONFIDENCE IS LOWER, ISOLATED CONVECTION APPEARS POSSIBLE ACROSS
PARTS OF SOUTHERN ARIZONA LATE SUNDAY AFTERNOON WHERE MODEST
LOW-LEVEL MOISTURE ADVECTION, COUPLED WITH AMPLE DAYTIME HEATING,
STEEP MID-LEVEL LAPSE RATES, AND WEAK ASCENT FROM A MID-LEVEL
IMPULSE MAY SUPPORT HIGH-BASED CONVECTION. BASED ON FORECAST
THERMODYNAMIC PROFILES, CONDITIONS MAY BE SUPPORTIVE OF STRONG
DOWNBURST WINDS. HOWEVER, CONFIDENCE IN STORM COVERAGE AND THE
SEVERE WIND POTENTIAL IS TOO LOW FOR HIGHLIGHTS.

VALID 271200Z - 281200Z
...CRITICAL FIRE WEATHER AREA FOR PARTS OF WESTERN OKLAHOMA...THE
EASTERN TEXAS/OKLAHOMA PANHANDLES...AND FAR SOUTH-CENTRAL KANSAS...
...SYNOPSIS...
UPPER-LEVEL RIDGING CENTERED OVER NORTHERN MEXICO AND WEST TEXAS
WILL REMAIN IN PLACE TODAY AS A MID-LEVEL SHORTWAVE TROUGH MOVES
SOUTHEASTWARD ACROSS THE GREAT LAKES AND NORTHEAST. AT THE SURFACE,
STRONG HIGH PRESSURE WILL SHIFT SOUTHEASTWARD FROM THE NORTHERN
GREAT PLAINS INTO THE MIDWEST WHILE A COLD FRONT PROGRESSES
SOUTHWARD ACROSS THE SOUTHERN GREAT PLAINS AND SOUTHEAST.
...EASTERN TX/OK PANHANDLES INTO WESTERN OK AND FAR SOUTH-CENTRAL
KS...
BROAD NORTH-NORTHEASTERLY POST-FRONTAL FLOW AMID A DRY AIR MASS WILL
ENCOMPASS PORTIONS OF THE CENTRAL/SOUTHERN GREAT PLAINS TODAY. WHILE
THE LATEST GUIDANCE INDICATES RH VALUES WILL REMAIN MORE MARGINAL
(20-25%), RECEPTIVE FUELS, SUSTAINED NORTHEASTERLY SURFACE WINDS OF
20-25 MPH, AND THE POTENTIAL FOR OCCASIONAL WIND GUSTS OF 30-40 MPH
(LOCALLY HIGHER) SHOULD SUPPORT A PERIOD OF CRITICAL FIRE WEATHER
CONCERNS FROM THE EASTERN TX/OK PANHANDLES INTO FAR SOUTH-CENTRAL
KANSAS.
FARTHER NORTHEAST, MINIMUM RH VALUES ARE FORECAST TO RANGE FROM
20-30% ACROSS MUCH OF CENTRAL/EASTERN KANSAS NORTHWARD INTO EASTERN
NEBRASKA, SOUTHWESTERN IOWA, AND NORTHWESTERN MISSOURI. COUPLED WITH
RECEPTIVE FUELS AND SUSTAINED SURFACE WINDS OF 15-20 MPH, ELEVATED
TO LOCALLY CRITICAL FIRE WEATHER CONDITIONS ARE EXPECTED THIS
AFTERNOON, WITH THE EXCEPTION BEING ACROSS AREAS THAT SAW
APPRECIABLE RAINFALL THURSDAY EVENING.
...EASTERN ARIZONA INTO SOUTHWESTERN NEW MEXICO...
A BACKDOOR COLD FRONT WILL PROGRESS SOUTH-SOUTHWESTWARD THROUGH
PORTIONS OF THE SOUTHWEST TODAY. DRY AND BREEZY CONDITIONS ARE
FORECAST IN THE WAKE OF THIS FRONT, WITH THE LATEST GUIDANCE
DEPICTING A CORRIDOR OF 15-25 MPH SUSTAINED SOUTHEASTERLY SURFACE
WINDS OVERLAPPING LOW RH AROUND 20%. THESE CONDITIONS ATOP RECEPTIVE
FUELS ARE EXPECTED TO PROMOTE A FEW HOURS OF ELEVATED FIRE WEATHER
CONDITIONS THIS AFTERNOON, PARTICULARLY IN THE VICINITY OF THE WHITE
MOUNTAINS AND GILA REGION.

VALID 281200Z - 291200Z
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE CENTRAL/NORTHERN
GREAT PLAINS......
...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF SOUTHERN GEORGIA INTO
SOUTHERN SOUTH CAROLINA...
...SYNOPSIS...
SURFACE HIGH PRESSURE WILL SHIFT EASTWARD FROM THE MIDWEST TO THE
EAST COAST IN THE WAKE OF A ROBUST MID-LEVEL TROUGH MOVING ACROSS
THE NORTHEAST ON D2/SATURDAY. SIMULTANEOUSLY, ENHANCED ZONAL,
MID-LEVEL FLOW ACROSS THE NORTHERN/CENTRAL ROCKIES WILL PROMOTE LEE
TROUGHING OVER THE HIGH PLAINS, WITH A TIGHTENED PRESSURE GRADIENT
AND STRONG LOW-LEVEL JET DEVELOPING BETWEEN THE SURFACE HIGH AND LEE
TROUGHING.
...CENTRAL GREAT PLAINS...
THE AFOREMENTIONED SURFACE PRESSURE GRADIENT AND LOW-LEVEL JET WILL
YIELD STRONG, SUSTAINED SOUTHERLY FLOW OF 20-30 MPH ACROSS MUCH OF
THE CENTRAL GREAT PLAINS. WITH RECEPTIVE FUELS IN PLACE AND RH
VALUES FORECAST TO FALL TO 15-20%, CRITICAL FIRE WEATHER CONDITIONS
ARE FORECAST SATURDAY AFTERNOON FROM PORTIONS OF THE OKLAHOMA
PANHANDLE NORTHEASTWARD TO SOUTHWESTERN MINNESOTA, WESTERN IOWA, AND
SOUTHEASTERN SOUTH DAKOTA. BOUNDARY LAYER MIXING AND STRONG 850 MB
FLOW OF 30-40+ KTS WILL ALSO SUPPORT THE POTENTIAL FOR PERIODIC WIND
GUSTS OF 35-45 MPH. ELEVATED FIRE WEATHER CONDITIONS ARE EXPECTED
ACROSS ADJACENT AREAS OF THE CENTRAL GREAT PLAINS WHERE SUSTAINED
SOUTHERLY SURFACE WINDS OF 15-25 MPH ARE FORECAST TO OVERLAP REDUCED
RH VALUES OF 20-25%, EXCEPT FOR PORTIONS OF CENTRAL/EASTERN KANSAS
THAT SAW MORE APPRECIABLE RAINFALL THURSDAY EVENING.
...PORTIONS OF THE CENTRAL HIGH PLAINS...
MODEST ZONAL, MID-LEVEL FLOW ACROSS THE CENTRAL/NORTHERN ROCKIES
WILL FAVOR DRY, DOWNSLOPE WINDS IN THE LEE OF THE SOUTHERN AND
CENTRAL ROCKIES DURING THE AFTERNOON ON SATURDAY. SUSTAINED WESTERLY
SURFACE WINDS OF 15-20 MPH ARE FORECAST TO OVERLAP VERY LOW RH OF
10-15% ACROSS PORTIONS OF SOUTHERN WYOMING AND SOUTHEASTERN
COLORADO. WITH RECEPTIVE FUELS IN PLACE ACROSS THESE REGIONS, A
PERIOD OF ELEVATED FIRE WEATHER CONDITIONS IS EXPECTED SATURDAY
AFTERNOON. LOCALIZED CRITICAL CONDITIONS WILL ALSO BE POSSIBLE
ACROSS PORTIONS OF SOUTHEASTERN WYOMING, PARTICULARLY IN THE LEE OF
THE LARAMIE RANGE, WHERE MODEST MID-LEVEL FLOW (30-40 KTS AROUND
600-700 MB) MAY SUPPORT OCCASIONAL GUSTS OF 35-45 MPH.
...PORTIONS OF THE SOUTHEAST...
DRY AND BREEZY CONDITIONS ARE FORECAST ACROSS MUCH OF THE
SOUTHEASTERN US ALONG THE SOUTHERN PERIPHERY OF THE SURFACE HIGH.
SUSTAINED NORTHEASTERLY SURFACE WINDS OF 10-15 MPH OVERLAPPING
REDUCED RH OF 25-35% AMID DRY, ANTECEDENT CONDITIONS WILL SUPPORT A
WIDESPREAD AREA OF ELEVATED FIRE WEATHER CONCERNS. SOME GUIDANCE
INDICATES RH VALUES MAY FALL TO AS LOW AS ~20% ACROSS PORTIONS OF
THIS REGION. CRITICAL HIGHLIGHTS HAVE BEEN ADDED TO PORTIONS OF
SOUTHEASTERN GEORGIA AND SOUTHERN SOUTH CAROLINA WHERE CONFIDENCE IS
HIGHEST IN A PERIOD OF OVERLAP BETWEEN SUSTAINED WINDS OF 15-20 MPH
AND MINIMUM RH VALUES OF 20-25% (LOCALLY LOWER). THE POTENTIAL FOR
EXPANSION OF THIS CRITICAL AREA WILL BE MONITORED IN FUTURE
OUTLOOKS.
