THE AREA REMAINS IN A NORTHEASTERLY UPPER FLOW PATTERN BETWEEN AN
UPPER RIDGE TO THE WEST AND AN UPPER LOW OFF THE WEST COAST OF
FLORIDA. THE UPPER RIDGE WILL CONTINUE TO MOVE WESTWARD AND
WEAKEN WHILE THE UPPER LOW MEANDERS OFF THE COAST OF FLORIDA AN
EVENTUALLY GETS ABSORBED INTO THE UPPER LEVEL FLOW AND MOVES
NORTHEAST BY TUESDAY. PRECIPITABLE WATER VALUES CONTINUE TO
INCREASE AS ATLANTIC MOISTURE MOVES INTO THE AREA AROUND THE UPPER
LOW. THE WEAKENING RIDGE ALONG WITH INCREASING MOISTURE WILL
ALLOW SCATTERED MAINLY AFTERNOON SHOWERS AND STORMS TO DEVELOP THE
REST OF TODAY AND MONDAY. THE RIDGE REBUILDS TUESDAY INTO
WEDNESDAY WITH RAIN CHANCES DECREASING. A WEAK FRONT MOVES THROUGH
THE AREA LATE WEDNESDAY INTO THURSDAY WITH A DRIER AIRMASS MOVING
INTO THE AREA. THE LACK OF SIGNIFICANT MOISTURE AHEAD OF THE
FRONT ALONG WITH THE UPPER RIDGE WILL KEEP CONDITIONS DRY AS THE
FRONT MOVES THROUGH.
ABOVE NORMAL TEMPS IN THE LOW TO MID 90S CONTINUE THROUGH MIDWEEK
BEFORE SOME SLIGHTLY COOLER AND DRIER AIR MOVES INTO THE AREA
BEHIND THE FRONT LATE IN THE WEEK. /13
