DAY 1 FIRE WEATHER OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1108 AM CDT SUN AUG 30 2026
VALID 301700Z - 311200Z
NO CHANGES WERE MADE TO THE ELEVATED WIND/RH AREA OVER THE SOUTHERN
PLAINS AS THE FORECAST REMAINS ON TRACK AS WAS PREVIOUSLY DESCRIBED.
AN AREA OF ISOLATED DRY THUNDERSTORMS WAS INTRODUCED OVER PORTIONS
OF THE NORTHERN HIGH PLAINS. LIFT FROM BOTH TERRAIN AND DYNAMIC
FORCING FROM A MID-LEVEL JET STREAK WILL IMPACT THE AREA THIS
AFTERNOON AMID LIMITED, BUT SUFFICIENT, MOISTURE (PRECIPITABLE WATER
VALUES NEAR 0.5-0.7") AND INSTABILITY (100-300 J/KG CAPE).
HIGH-BASED AND FAST MOVING (30+ KTS STORM MOTION) STORMS AMID A DRY
AND WINDY SUB-CLOUD LAYER WILL SUPPORT A LIGHTNING IGNITION RISK
THIS AFTERNOON. WHILE THE HIGHEST COVERAGE OF STORMS IS ANTICIPATED
TO REMAIN NORTH AND SOUTH OF THE DRAWN AREA, THE RISK OF DRY
THUNDERSTORM ACTIVITY FROM CENTRAL WY INTO FAR SOUTHWEST SD WILL
EXCEED 10% OVER VERY DRY FUELS. SEE OUR DAY 1 CONVECTIVE OUTLOOK FOR
MORE DETAILS ON COINCIDENT/NEARBY SEVERE WIND CONCERNS.

..SYNOPSIS
MODERATE TO STRONG MID-LEVEL FLOW ACROSS PARTS OF THE
CENTRAL/NORTHERN HIGH PLAINS WILL PROMOTE A SURFACE TROUGH FROM THE
NORTHERN PLAINS SOUTHWARD INTO THE SOUTHERN HIGH PLAINS. NEAR THIS
TROUGH, STRONG HEATING AND MIXING WILL ALLOW RH TO DROP TO AROUND
20-25% FROM THE TEXAS PANHANDLE INTO WESTERN OKLAHOMA AND
SOUTH-CENTRAL KANSAS. MODESTLY ENHANCED WINDS JUST ABOVE THE SURFACE
WILL HELP DRIVE 15-20 MPH WINDS (WITH STRONGER GUSTS) ACROSS THESE
AREAS. AREAS OF DROUGHT-STRESSED FUELS WILL CONTINUE TO SUPPORT THE
DEVELOPMENT OF ELEVATED FIRE WEATHER CONCERNS DURING THE AFTERNOON.
