DAY 3 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0228 AM CDT MON OCT 27 2025
VALID 291200Z - 301200Z
..NO THUNDERSTORM AREAS FORECAST
..SUMMARY
THUNDERSTORMS ARE UNLIKELY WEDNESDAY.
..SYNOPSIS
A DEEP UPPER LOW OVER THE CENTRAL US WILL CONTINUE TO INTENSIFY
BEFORE MERGING WITH A BROADER TROUGH OVER THE EASTERN US WEDNESDAY
AND WEDNESDAY NIGHT. A SURFACE LOW OVER THE MID SOUTH WILL DEEPEN
AND MOVE TOWARD THE ATLANTIC COAST AS A STRONG COLD FRONT CONTINUES
TO PUSH OFFSHORE THROUGH THE GULF AND SOUTHEAST. HIGH PRESSURE WILL
DEVELOP WITHIN THE POST-FRONTAL AIR MASS SUPPORTING WIDESPREAD
OFFSHORE FLOW AND DRIER CONDITIONS ACROSS MUCH OF THE CONUS.
THE ONLY EXCEPTION WILL BE ACROSS FAR SOUTH FL AND THE IMMEDIATE MID
ATLANTIC COAST WHERE REMAINING SOUTHERLY WINDS WILL SUPPORT MODEST
SURFACE MOISTURE FOR PART OF THE DAY. HOWEVER, THE RELATIVELY
SHALLOW NATURE OF THE MOISTURE AND MID-LEVEL DRYING/SUBSIDENCE
SOUTHEAST OF THE JET MAX WILL OVERSPREAD THE AREA AHEAD OF THE
ADVANCING FRONT. THIS SHOULD LIMIT THUNDERSTORM POTENTIAL BEFORE THE
COLD FRONT SCOURS THE REMAINING MOISTURE OFFSHORE. THUS,
THUNDERSTORM CHANCES CURRENTLY APPEAR TO BE BELOW 10% OVER THE
CONUS.
