The episode as NWS MLB wrote it up.

Large hail, up to golf ball sized was reported across DeBary, Sanford, Lake Mary, Altamonte Springs and Oakland. Strong winds also felled numerous trees and large tree branches leading to damage to homes and cars in DeBary, Astatula, and Lake Mary.

CURRENT-TONIGHT...DEEP LAYERING MOISTENING OF THE ATMOSPHERE ONGOING WITH PRECIPITABLE WATER VALUES IN EXCESS OF 1.80 INCHES FORECAST ACROSS THE INTERIOR. COOL 500MB TEMPERATURES AROUND -10C WITH DECENT DIFFLUENCE ALOFT AT 250 MB. SHORTWAVE RIDGING PASSING OVER THE FL PENINSULA TODAY WILL EMERGE OFF OF THE EAST COAST THIS EVENING. SCATTERED SHOWERS AND STORMS DEVELOPING ALONG THE INLAND MOVING EAST COAST SEA BREEZE ALREADY EARLY THIS AFTERNOON.

CONVECTION WILL CONTINUING INCREASING IN COVERAGE/INTENSITY THROUGH EARLY EVENING INLAND FROM THE EAST COAST. THERE DOES APPEAR TO BE A SLIGHT WESTWARD DRIFT PRESENTLY BUT WITH THE OVERALL WEAK WIND PROFILE EXPECT SLOW/ERRATIC MOVEMENT FOR THE REMAINDER OF THE PERIOD. A LARGER BOUNDARY COLLISION WILL OCCUR OVER THE WEST CENTRAL PENINSULA BETWEEN BOTH EAST/WEST COAST SEA BREEZES EARLY THIS EVENING. A FEW LOCAL STRONG STORMS LIKELY WITH FREQUENT LIGHTNING...GUSTY WINDS UP TO AROUND 50 MPH...SMALL HAIL AND LOCALLY HEAVY DOWNPOURS ALL IN PLAY. SLOW MOVEMENT OF CELLS MAY CAUSE LOCALIZED FLOODING IN SOME AREAS. ACTIVITY WILL FINALLY DISSIPATE LATE THIS EVENING WITH CLOUD DEBRIS SLOWLY ERODING THROUGH THE NIGHT.

A 250MB JET STREAK (60-70 KNOTS) IS FORECAST TO ROUND THE BASE OF THE TROUGH AND NOSE INTO THE FLORIDA PENINSULA BRINGING INCREASED MOISTURE AND DIVERGENCE ALOFT. COMBINED WITH COLD TEMPERATURES ALOFT (-10C AT 500 MB)...SHOWER/STORM CHANCES WILL BE HIGH WITH 60 TO 70 PERCENT CHANCES AREAWIDE. EXPANSIVE CLOUDINESS WILL LIMIT SURFACE HEATING/INSTABILITY...THOUGH UNUSUALLY STRONG MID/UPPER LEVEL DYNAMICS WILL STILL PROVIDE A THREAT OF AT LEAST A FEW STRONG/MARGINALLY SEVERE STORMS IN THE AFTERNOON. STEERING FLOW REMAINS RELATIVELY POOR SO THE THREAT FOR HEAVY RAIN WILL STILL REMAIN. M80S FOR HIGHS ALONG THE COAST WITH U80S STILL POSSIBLE ACROSS THE INTERIOR. ...PREVIOUS EXTENDED FORECAST DISCUSSION... WED-SUN...LOW CONFIDENCE IN THE FCST FROM MIDWEEK ONWARD AS A GENUINE SHIFT IN THE LCL WX PATTERN IS ANTICIPATED...BUT CONSIDERABLE UNCERTAINTY REMAINS WRT HOW THAT PATTERN SHIFT WILL MANIFEST ITSELF.
