DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1100 AM CDT FRI OCT 31 2025
VALID 311630Z - 011200Z
..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORM POTENTIAL WILL REMAIN LOW THROUGH TONIGHT.
..SYNOPSIS AND DISCUSSION
WITH LONGWAVE UPPER TROUGHING DOMINATING EAST OF THE ROCKIES AND THE
PREVALENCE OF CONTINENTAL SURFACE TRAJECTORIES, THE LARGE-SCALE
PATTERN WILL REMAIN GENERALLY UNFAVORABLE FOR THUNDERSTORMS OVER THE
CONUS TODAY. OCCASIONAL LIGHTNING FLASHES COULD OCCUR ACROSS
NORTHERN NEW ENGLAND WITH FOCUSED ASCENT NEAR A SURFACE LOW AND
NORTHWARD-SHIFTING FRONT, BUT THIS POTENTIAL WILL REMAIN LIMITED AND
FURTHER DIMINISH THIS AFTERNOON. WEAK ELEVATED CONVECTION MAY
DEVELOP LATE TONIGHT ACROSS WEST-CENTRAL TEXAS AS LOW-LEVEL WARM
ADVECTION INCREASES, BUT FORECAST THERMODYNAMIC PROFILES SUGGEST
THAT CHARGE SEPARATION IS UNLIKELY PRIOR TO 12Z SATURDAY.
