NWS STORM PREDICTION CENTER NORMAN OK
0139 AM CDT SUN OCT 25 2026
VALID 271200Z - 281200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED ON TUESDAY.
..SYNOPSIS
A SERIES OF UPPER TROUGHS WILL MIGRATE ACROSS THE NORTH-CENTRAL U.S.
ON TUESDAY WHILE UPPER RIDGING AMPLIFIES OVER THE EAST. SOUTHERLY
LOW-LEVEL FLOW WILL MAINTAIN MODEST BOUNDARY LAYER MOISTURE (MAINLY
50S F DEWPOINTS) FROM OK/KS INTO THE UPPER MIDWEST/GREAT LAKES, WITH
60S F DEWPOINTS POSSIBLE FURTHER SOUTH ACROSS TX. A SURFACE FRONT
INITIALLY OVER KS TO CENTRAL IA WILL LIFT NORTHWARD THROUGH THE
PERIOD IN RESPONSE TO INCREASING LOW-LEVEL WARM ADVECTION AHEAD OF A
SHORTWAVE TROUGH TRAVERSING THE NORTHERN PLAINS. ISOLATED
THUNDERSTORMS ARE POSSIBLE WITHIN THE BROADER WARM ADVECTION REGIME
ACROSS PARTS OF THE PLAINS FROM SOUTH TX INTO THE MID-MO VALLEY.
MODEST INSTABILITY AND GENERALLY WEAK VERTICAL SHEAR WILL PRECLUDE
SEVERE POTENTIAL.
