GULF OF MEXICO...
SURFACE RIDGE OF HIGH PRESSURE IS OVER THE W GULF OF MEXICO W OF 85W. OVERCAST LOW CLOUDS ARE OVER BUILDING THE E SLOPES OF THE SIERRA MADRES S OF 21N. LOW PRESSURE CONTINUES TO SLIDE ACROSS FLORIDA AND E OF THE CAROLINA COAST . THIS SYSTEM IS LINKED TO A CUT-OFF UPPER LOW CENTERED NEAR CHARLESTON SC AND BROAD TROUGHING REACHING DOWN TO S FLORIDA. MID-LEVEL INSTABILITY ASSOCIATED WITH THE CUT-OFF LOW IS ALSO PRODUCING A BAND OF LOW CLOUDS ACROSS SRN GA/AL/MS/ THE FL PANHANDLE/ AND THE NE GULF WATERS. IN ADDITION...A WEAK 1009 MB SFC LOW JUST E OF COCOA BEACH FL EXTENDS A TROUGH ACROSS CENTRAL FLORIDA AND THE E GULF WATERS BUT IS MERELY PROVIDING A WIND SHIFT AND PATCHY CUMULUS CLOUDS. EXPECT NE FLOW TO DOMINATE THE GULF WITHIN 24 HOURS AS HIGH PRESSURE MOVES E OVER THE UNITED STATES EAST COAST.

ATLANTIC...
...IN THE UPPER LEVELS...DEEP-LAYERED TROUGH IS SPREADING OVER THE W ATLANTIC WATERS N OF 22N BETWEEN 70W-80W....
