DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0214 AM CDT WED AUG 27 2025
VALID 291200Z - 301200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
A COUPLE OF STRONG STORMS CANNOT BE RULED OUT FROM THE SABINE RIVER
VALLEY TO THE SOUTHERN HIGH PLAINS.
..SYNOPSIS
AN UPPER-LEVEL CUTOFF LOW WILL MEANDER OVER NEW ENGLAND WHILE UPPER
RIDGING PREVAILS OVER THE WESTERN AND CENTRAL U.S. ON FRIDAY. AS
SURFACE HIGH PRESSURE REMAINS IN PLACE ACROSS THE GREAT LAKES AND
INTERIOR WEST, WEAK SURFACE TROUGHING WILL ENCOURAGE LOW-LEVEL
MOISTURE RETURN ACROSS THE PLAINS STATES. WITH DAYTIME HEATING,
THUNDERSTORMS MAY DEVELOP OFF OF A REMNANT OUTFLOW BOUNDARY ACROSS
CENTRAL TX INTO THE SABINE RIVER VALLEY THAT WAS LEFT BEHIND BY
STORMS FROM DAY 2. STORMS ARE ALSO EXPECTED TO DEVELOP OFF OF THE
HIGHER TERRAIN ACROSS THE HIGH PLAINS GIVEN MODEST UPSLOPE LOW-LEVEL
FLOW. ADEQUATE LOW-LEVEL MOISTURE, OVERSPREAD BY MODEST MID-LEVEL
LAPSE RATES/VERTICAL WIND SHEAR, WILL SUPPORT ISOLATED STRONG
THUNDERSTORMS ACROSS THE SOUTHERN HIGH PLAINS TOWARD THE SABINE
RIVER VALLEY (ALONG THE OUTFLOW BOUNDARY). SUB-SEVERE WIND/HAIL
SHOULD ACCOMPANY THE STRONGER STORMS. HOWEVER, MEDIOCRE
THERMODYNAMIC VERTICAL PROFILES (EVIDENT VIA FORECAST SOUNDINGS),
SUGGEST THAT SEVERE STORMS SHOULD BE QUITE SPARSE, WITH NO SEVERE
PROBABILITIES INTRODUCED THIS OUTLOOK.
