DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1155 AM CDT TUE OCT 21 2025
VALID 221200Z - 231200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE STORMS ARE NOT FORECAST ON WEDNESDAY OR WEDNESDAY NIGHT.
..NEW ENGLAND
AN OCCLUDED CYCLONE WILL STEADILY MOVE NORTHEAST FROM THE LAKE HURON
VICINITY INTO QC DURING THE PERIOD. THE LOW-LEVEL WARM CONVEYOR
AHEAD OF THE BENT-BACK OCCLUDED FRONT WILL PIVOT NORTHEAST ACROSS
AND EVENTUALLY OUT OF NEW ENGLAND THROUGH THE DAY. MEAGER BUOYANCY
IS ANTICIPATED WHERE STRONG DEEP-LAYER SHEAR CAN PERSIST OVER
EASTERN/COASTAL NEW ENGLAND MIDDAY INTO THE AFTERNOON. SCATTERED
LOW-TOPPED SHOWERS SHOULD DOMINATE, WITH ISOLATED EMBEDDED
THUNDERSTORMS POSSIBLE. DESPITE WEAK CONVECTIVE INTENSITY, FAST
LOW-LEVEL SOUTH-SOUTHEASTERLIES, MAINLY ACROSS ME, MIGHT FOSTER A
FEW LOCALLY STRONG GUSTS.
..SOUTHWEST
A COMPACT SHORTWAVE TROUGH MOVING ACROSS SOUTHERN CA INTO THE LOWER
CO VALLEY WILL AID IN SCATTERED THUNDERSTORMS FROM THE SIERRA NV
MOUNTAINS TO THE FOUR CORNERS VICINITY ON WEDNESDAY AFTERNOON AND
EVENING. MUCH OF THIS ACTIVITY SHOULD BE HIGH-BASED AND LOW-TOPPED
OVER LOWER ELEVATIONS. MEAGER BUOYANCY AND WEAK LOWER-LEVEL FLOW
WILL MINIMIZE SEVERE POTENTIAL. BUT A FEW LOCALLY STRONG GUSTS ARE
POSSIBLE AMID LARGE SURFACE TEMPERATURE-DEW POINT SPREADS.
