AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE TAMPA BAY-RUSKIN, FL 246 PM EST SUN MAR 31 1996 APPARENTLY THE STRONG 800MB CAP IS HOLDING THINGS THUS FAR ACROSS SOUTH FLORIDA...BUT WITH TEMPS AT FMY IN MID/UPPER 80S AND EVIDENCE OF SEA BREEZE ON SATELLITE...IT WONT BE LONG BEFORE ISOL SVR TSTMS ERUPT. MOST OF THOSE TSTMS WILL LIKELY STAY JUST SOUTH AND EAST OF THE CWA. MAIN PRECIP WILL...ONCE AGAIN...BE FROM LARGE AREA OF CONVECTION AHEAD OF VORT MAX THAT WILL MOVE ACROSS THE PENINSULA THIS EVG. MAIN THREAT FROM THIS AREA WILL BE LCLLY HVY RAIN AND SOME WIND GUSTS. ONCE THIS PRECIP ENDS...THINGS SHOULD BE MUCH QUIETER. EXPECT COLD FRONT TO SWING THROUGH MON MORNING AND DRY MOST OF THE ATMOS OUT. THERE IS ANOTHER STRONG VORT THAT WILL SWING THRU THE STATE MONDAY EVENING...BUT WITH MOST OF THE MOISTURE GONE I DONT EXPECT MUCH MORE THAN AN INCREASE IN CLOUDS/GUSTY WINDS ACROSS THE FA. ANY TSTMS THAT FIRE WILL BE CONFINED TO OVER THE GULF STREAM. TEMP/POP THOUGHTS... BKV 59/72/47/72 8100 TPA 63/73/55/73 8200 FMY 65/78/59/77 8300 NASH
