DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0648 AM CDT WED MAR 18 2026
VALID 181300Z - 191200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
ISOLATED THUNDERSTORMS WILL BE POSSIBLE TODAY ACROSS FAR SOUTH
FLORIDA.
..SYNOPSIS
MORNING WATER VAPOR IMAGERY SHOWS A PROMINENT MID-LEVEL RIDGE OVER
THE SOUTHWESTERN STATES, WITH FAST NORTHWEST FLOW ALOFT OVER MUCH OF
THE REST OF THE CONUS. THIS PATTERN WILL PREVENT THE RETURN OF GULF
MOISTURE, AND PRECLUDE ORGANIZED THUNDERSTORMS OVER MOST AREAS.
THE ONE EXCEPTION WILL BE OVER SOUTH FL, IN VICINITY OF A STALLED
BOUNDARY. WHILE AN ISOLATED LIGHTNING STRIKE OR TWO WILL BE
POSSIBLE OVER LAND, MUCH OF THE THUNDERSTORM RISK WILL AFFECT
OFFSHORE WATERS. NO SEVERE STORMS ARE ANTICIPATED.
