A GRADUALLY LESSENING OF THE UPPER HIGH PRESSURE AREA CENTERED

WESTWARD OVER THE CENTRAL CONUS THROUGH THE REMAINDER OF THE WEEK
AS AN UPPER TROUGH DIGS SOUTHWARD ALONG THE EASTERN SEABOARD. THE
MID-LOWER HIGH PRESSURE AREA OVER THE TENNESSEE VALLEY WILL ALSO
GRADUALLY WEAKEN WHILE A MID-LOWER EASTERLY WAVE MOVES WEST-
NORTHWESTWARD OVER THE EASTERN AND NORTHERN GULF TODAY THROUGH
FRIDAY.
AN ENHANCED DEEP EASTERLY FLOW BETWEEN THESE TWO SYSTEMS WILL
ALLOW DEEP MOISTURE TO ENTER INTO THE REGION WITH PWATS INCREASING
UP TO AROUND 2.4" BY NOON FRIDAY. MODELS ARE NOW SHOWING A

WE REMAIN IN THIS WETTER PATTERN THROUGH AT LEAST MONDAY AS THE
BASE OF THE EASTERN SEABOARD UPPER TROUGH REMAINS OVER THE
SOUTHEAST STATES ALONG WITH A POSSIBLY BACKDOOR COLD FRONT
ENTERING INTO THE FORECAST AREA ON SUNDAY AND THEN MEANDERS
