DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0149 AM CDT FRI OCT 16 2026
VALID 181200Z - 191200Z
..NO SEVERE THUNDERSTORM AREAS FORECAST
..SUMMARY
SEVERE THUNDERSTORMS ARE NOT EXPECTED ANYWHERE ACROSS THE CONTIGUOUS
UNITED STATES ON SUNDAY.
..SYNOPSIS
UPPER RIDGING WILL PREVAIL ACROSS THE CENTRAL CONUS AS A WEAK 500 MB
CUTOFF LOW MEANDERS OFF OF THE EAST COAST AND BROAD, LOW-AMPLITUDE
UPPER TROUGHING DOMINATES THE INTERIOR WEST ON SUNDAY. A SURFACE
ANTICYCLONE WILL OVERSPREAD THE CONUS EAST OF THE MS RIVER WHILE
SURFACE TROUGHING OCCURS ACROSS THE GREAT PLAINS. DESPITE THIS
SURFACE TROUGHING, MEDIUM-RANGE GUIDANCE SHOWS MOIST TRAJECTORIES
ACROSS THE GULF ORIENTED AWAY FROM THE U.S. SHORELINE, SUGGESTING
THAT A STABLE AIRMASS WILL REMAIN OVER THE CONUS. THEREFORE,
THUNDERSTORM POTENTIAL SHOULD BE HINDERED OVER MOST LOCALES. THE ONE
EXCEPTION MAY BE SOUTHERN FL INTO THE KEYS, WHERE LINGERING
LOW-LEVEL MOISTURE IN A POST-COLD-FRONTAL AIRMASS MAY SUPPORT
ISOLATED THUNDERSTORM DEVELOPMENT DURING THE AFTERNOON.
