DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1212 AM CDT MON OCT 26 2026
VALID 271200Z - 281200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE UNLIKELY TUESDAY.
..SYNOPSIS
A SERIES OF UPPER SHORTWAVE TROUGHS WILL MOVE ACROSS THE NORTHERN
PLAINS AND UPPER MIDWEST, AS WELL AS THE SOUTHERN PLAINS TO THE
MID-MS VALLEY ON TUESDAY. BOUNDARY LAYER MOISTURE WILL REMAIN
MODEST, WITH DEWPOINTS GENERALLY IN THE 50S ACROSS THE PLAINS AND
MIDWEST, WHILE 60S DEWPOINTS REMAIN CONFINED TO CENTRAL/SOUTH TX.
WARMER MIDLEVEL TEMPERATURES WILL PRECLUDE MUCH DESTABILIZATION FROM
THE MID/LOWER MO VALLEY INTO THE UPPER MIDWEST. THIS WILL LARGELY
LIMIT THUNDERSTORM ACTIVITY AND NEGATE SEVERE THUNDERSTORM POTENTIAL
DESPITE STRONGER SOUTHWESTERLY FLOW ALOFT. FURTHER SOUTH ACROSS TX,
ISOLATED THUNDERSTORMS ARE MORE LIKELY WHERE WEAK DESTABILIZATION
WILL OCCUR AMID MARGINALLY BETTER MOISTURE AND STRONGER HEATING.
HOWEVER, VERTICAL SHEAR WILL REMAIN MODEST AS THE REGION IS
DISPLACED TO THE SOUTH OF STRONGER FLOW ACROSS THE NORTH-CENTRAL
U.S. FURTHERMORE, LARGE-SCALE ASCENT WILL BE NEBULOUS WITHIN A BROAD
LOW-LEVEL WARM ADVECTION REGIME. OVERALL, SEVERE THUNDERSTORM
POTENTIAL APPEARS LOW FOR TUESDAY.
