REGION, AND UPPER LEVEL "EASTERLY" WAVE/DISTURBANCE WILL CROSS
FLORIDA AND MOVE OVER THE GULF FRIDAY AND SATURDAY. MOISTURE WILL
INCREASE RATHER DRAMATICALLY ACROSS THE AREA DURING THIS TIME WHICH
WILL HELP SUPPORT MAINLY AFTERNOON AND EVENING SHOWERS/STORMS. AT
THIS TIME, NOT SEEING MUCH TO SUPPORT ANY "SEVERE" STORMS FRIDAY BUT
WILL HAVE TO MONITOR INITIAL CONVECTION POTENTIALLY TAPPING INTO
HIGHER DCAPE VALUES - WHICH COULD RESULT IN ISOLATED MICROBURSTS AS
STORMS GENERALLY MOVE SOUTH ACROSS THE AREA (GIVEN FLOW AROUND UPR

OVER THE WEEKEND THROUGH EARLY NEXT WEEK, A CLOSED MID-LEVEL LOW
WILL SLIDE FROM THE FLORIDA PENINSULA INTO THE EASTERN GULF. WARM
AND MOIST AIR WRAPPING AROUND THE LOW FROM THE ATLANTIC WILL POOL
ACROSS THE AREA, SUPPORTING SCATTERED SHOWERS AND STORMS EACH DAY.
HIGH TEMPERATURES WILL REMAIN IN THE 90S, COMBINING WITH DEWPOINTS
IN THE 70S TO DRIVE HEAT INDEX VALUES INTO THE UPPER 90S TO LOW 100S.
CONFIDENCE IN THE FORECAST STARTS TO DROP OFF BY THE TUESDAY-
WEDNESDAY TIMEFRAME, AS MODEL GUIDANCE HAS A LARGE SPREAD IN THE
POTENTIAL SYNOPTIC SETUP. SOME OF THE GUIDANCE KEEPS THE CUT OFF LOW
OVER THE EASTERN GULF, WHILE OTHER GUIDANCE HAS THE LOW GET ABSORBED
BY TROUGHING TO THE NORTH AND SHIFTING OUT OF THE AREA WITH DRIER
AND COOLER AIR MOVING IN WITH A WEDGE. THERE HAS BEEN A SLIGHT TREND
TOWARDS THE LATTER SOLUTION, BUT CONFIDENCE REMAINS LOW IN THE
FORECAST FOR MID TO LATE NEXT WEEK.
