DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1125 AM CST WED DEC 17 2025
VALID 181200Z - 191200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE POTENTIAL WILL BE LIMITED ON THURSDAY, BUT ISOLATED STRONG
WIND GUSTS ARE POSSIBLE ACROSS PORTIONS OF THE LOWER OHIO AND
TENNESSEE VALLEYS.
..SYNOPSIS
A STRONG UPPER TROUGH WILL MOVE ACROSS MIDWEST ON THURSDAY WITH LOW
PRESSURE MOVING ACROSS THE GREAT LAKES. A COLD FRONT WILL EXTEND
SOUTH FROM THIS LOW WITH WIND SHIFT MOVING ACROSS THE OH AND TN
VALLEYS DURING THE DAY AND INTO THE EVENING. MINIMAL DESTABILIZATION
IS FORECAST AHEAD OF THE FRONT AS CLOUDS AND EARLY DAY PRECIPITATION
HAMPER HEATING. MOSTLY ELEVATED INSTABILITY IS FORECAST, THOUGH
SHEAR PROFILES WILL BE STRONG. DESPITE A MARGINAL/COOL BOUNDARY
LAYER ACROSS THE WARM SECTOR, DEEPER ASCENT ALONG THE COLD FRONT
COULD SUPPORT SHALLOW MOIST CONVECTION CAPABLE OF AUGMENTING GUSTS
WITH THE FRONTAL PASSAGE.
ELSEWHERE, MOISTURE AND INSTABILITY WILL INCREASE OVERNIGHT WELL OFF
THE NC COAST, BUT SUPERCELLS DEVELOPING OVER THE WATER MAY
EVENTUALLY SKIRT THE OUTER BANKS OF NC TOWARD THE END OF THE PERIOD.
AT THIS TIME IT APPEARS THE INSTABILITY GRADIENT WILL REMAIN
OFFSHORE.
