DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1118 PM CST SUN FEB 22 2026
VALID 231200Z - 241200Z
..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS ARE NOT EXPECTED.
..DISCUSSION
LARGE-SCALE PATTERN DOES NOT APPEAR PARTICULARLY FAVORABLE FOR DEEP
CONVECTION CAPABLE OF GENERATING LIGHTNING DURING THE DAY1 PERIOD.
WHILE VERY WEAK BUOYANCY MAY EXIST NEAR THE SOUTHERN NEW ENGLAND
COAST, AS A DEEP CYCLONE EJECTS NORTHEAST TOWARD NOVA SCOTIA, THE
PROSPECT FOR LIGHTNING APPEARS TOO LOW TO WARRANT 10 PERCENT THUNDER
TODAY.
ANOTHER REGION WHERE VERY WEAK ELEVATED INSTABILITY IS EXPECTED TO
SUPPORT SHALLOW CONVECTION IS ACROSS NORTHWEST WA EARLY IN THE
PERIOD. SHORT-WAVE RIDGING WILL QUICKLY SPREAD ACROSS THIS REGION
AND THUNDERSTORMS ARE NOT ANTICIPATED.
