DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0225 PM CDT FRI APR 17 2026
VALID 191200Z - 201200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED ON SUNDAY.
..DISCUSSION
AN AMPLIFIED LARGE-SCALE TROUGH WILL MOVE EASTWARD FROM THE GREAT
LAKES TO THE NORTHEAST ON SUNDAY, WHILE A RELATED COLD FRONT MOVES
OFF THE EASTERN SEABOARD. DESPITE POOR DEEP-LAYER LAPSE RATES, A
NARROW CORRIDOR OF DIURNAL HEATING AMID LOWER/MIDDLE 60S DEWPOINTS
(HIGHER OVER THE FL PENINSULA) AHEAD OF THE FRONT SHOULD SUPPORT
ISOLATED THUNDERSTORMS FROM THE COASTAL CAROLINAS SOUTHWARD ACROSS
PARTS OF THE FL PENINSULA. WEAK/NARROW BUOYANCY PROFILES WILL LIMIT
THUNDERSTORM INTENSITY AND THE SEVERE RISK.
