DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0207 AM CDT WED OCT 08 2025
VALID 101200Z - 111200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORM POTENTIAL APPEARS LOW ON FRIDAY.
..SYNOPSIS
AN UPPER RIDGE WILL PERSIST OVER THE PLAINS ON FRIDAY. MEANWHILE, A
SHORTWAVE UPPER TROUGH WILL MIGRATE EAST ACROSS THE GREAT LAKES
WHILE A SECOND UPPER TROUGH MOVES INLAND ACROSS THE PACIFIC
NORTHWEST.
A WEAK SURFACE FRONT WILL DEVELOP SOUTHEAST ACROSS THE UPPER MIDWEST
AS THE UPPER TROUGH EJECTS EASTWARD. SOME GUIDANCE SUGGESTS SHALLOW,
LOW-TOPPED CONVECTION MAY DEVELOP NEAR/JUST BEHIND THE FRONT ACROSS
THE GREAT LAKES, THOUGH LITTLE LIGHTNING MAY ACCOMPANY THIS
ACTIVITY.
MOISTURE WILL INCREASE NORTHWARD ACROSS MUCH OF THE WESTERN U.S.
AHEAD OF THE UPPER TROUGH AND IN RELATION TO HURRICANE PRISCILLA,
WHICH IS FORECAST BY NHC TO APPROACH THE NORTHERN BAJA PENINSULA ON
FRIDAY. ISOLATED THUNDERSTORMS ARE EXPECTED, BUT WEAK INSTABILITY
WILL LIMIT SEVERE POTENTIAL. ADDITIONAL STORMS ARE POSSIBLE ACROSS
PARTS OF FL AS A SURFACE COLD FRONT DEVELOPS SOUTH ACROSS THE
PENINSULA AND INTO THE GULF. POOR LAPSE RATES AND WEAK
INSTABILITY/SHEAR WILL PRECLUDE SEVERE POTENTIAL.
