NORTHEASTWARD ALONG THE EAST SIDE OF THE TROUGH. THE LOCAL AREA
WILL BE UNDER THE FAVORABLE RIGHT REAR QUADRANT OF THE UPPER JET
AS THE TROUGH SLOWLY MOVES EAST AND PUSHES THE FRONTAL BOUNDARY
INTO OUR AREA. PWATS WILL REMAIN NEAR 2 INCHES. SHOWERS/STORMS
PREVALENT OVER THE GULF WATERS WILL PUSH INLAND EARLY EACH
MORNING AND INCREASE IN COVERAGE FROM W TO E AS EMBEDDED SHORTWAVE
TROUGHS INTERACT WITH AN UNSTABLE LOW LEVEL AIRMASS AND LINGERING

ENCROACHING TROPICAL SYSTEM WILL BE THE FINAL DETERMINING FACTOR
LATE IN THIS PERIOD. AT THE SURFACE...A BACK-DOOR COLD FRONT
DRIFTS INTO NE FL WITH COASTAL TROUGH FORMING SUNDAY. GIVEN THE
VARIATIONS IN MODEL RUNS AND THE UNCERTAINTY WHERE THE TROPICAL
SYSTEM WILL TRACK...WILL KEEP STATUS QUO FOR NOW AND KEEP LOW END
CHANCE POPS EACH AFTERNOON. TEMPS WILL BE NEAR TO SLIGHTLY BELOW
