DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1154 PM CST TUE DEC 09 2025
VALID 101200Z - 111200Z
..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THE RISK FOR THUNDERSTORMS APPEARS LOW TODAY.
..SYNOPSIS
THE LARGE-SCALE PATTERN WILL FEATURE A RIDGE ACROSS THE WESTERN
CONUS WITH A TROUGH ACROSS THE EAST. A SURFACE LOW WILL DEEPEN BELOW
990MB AS IT MOVES FROM THE SOUTHERN GREAT LAKES TO THE NORTHEAST
DURING THE PERIOD. A COLD FRONT WILL EXTEND SOUTHWEST FROM THIS
SURFACE LOW AND BRING A REINFORCING COLD/DRY AIRMASS TO MUCH OF THE
CENTRAL AND EASTERN CONUS.
SIGNIFICANT MOISTURE (60F DEWPOINTS) WILL BE RELEGATED TO FAR SOUTH
FLORIDA. HOWEVER, EVEN HERE, NORTHERLY FLOW SHOULD PERSIST WITHIN
THE POST FRONTAL AIRMASS. THIS SHOULD KEEP ANY THUNDERSTORM
POTENTIAL WELL OFFSHORE. A BRIEF PERIOD OF SOUTHERLY RETURN FLOW
ACROSS THE WESTERN GULF MAY BRING SOME NEAR 60F DEWPOINTS TO THE
TEXAS COAST, BUT THIS SHOULD BE SHORT-LIVED AS A REINFORCING COLD
FRONT MOVES OFFSHORE THIS EVENING.
THUNDERSTORMS ARE NOT EXPECTED ACROSS THE CONUS TODAY.
