The episode as NWS MFL wrote it up.
A weak frontal boundary remained across South Florida for a second day as another short wave moved across the region during the afternoon hours allowing severe thunderstorms to develop over Palm Beach County. The storms produced wind damage and hail.
The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Miami, FL wrote its last area forecast discussion before the first event at Mar 6, 9:30 AM EST, 5 hours earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE MIAMI FL 930 AM EST THU MAR 6 2008 OVER THE LONG TERM...NO CHANGE TO THE CURRENT FORECAST PACKAGE. FOR THE SHORT TERM...FORECAST FOR NUMEROUS SHOWERS AND ISOLATED THUNDERSTORMS MAINLY FOR THE AFTERNOON ACROSS THE EASTERN HALF OF SOUTH FLORIDA STILL LOOKS REASONABLE. AND INSPECTION OF THE 12Z SOUNDING INDICATES THAT THE WEAK WINDS IN THE LOWER 10KFT AND THE PRESENCE OF LOW LEVEL CLOUDS ASSOCIATED WITH THE LINGERING BOUNDARY COULD RESULT IN AN ISOLATED CHANCE OF WATER SPOUTS TODAY. IN ADDITION THE SOUNDING AND RECENT WATER VAPOR IMAGERY INDICATE THAT SOME DRIER MID TO UPPER LEVEL AIR HAS PENETRATED THE REGION AND THIS COULD LEAD TO THE POSSIBILITY OF SMALL HAIL AND WIND GUSTS TO 40 TO 50 MPH WITH ANY THUNDERSTORMS...BUT MAINLY LATER THIS AFTERNOON AND EARLY EVENING. 60 .AVIATION... SOME LEFTOVER MID-LEVEL CLOUDS BETWEEN 6000-8000 FEET ACROSS SOUTH FLORIDA THIS MORNING FROM SHORTWAVE PASSING EAST OF AREA. SATELLITE IMAGERY SHOWS ADDITIONAL MID-LEVEL CLOUDS BACK OVER EASTERN GULF OF MEXICO POISED TO AFFECT AREA THIS AFTERNOON. DESPITE CLOUDINESS... WARM TEMPERATURES WILL LEAD TO SEA BREEZE DEVELOPMENT OVER ALL TERMINALS BY 16Z...WHICH WILL EVENTUALLY CAUSE SHOWERS AND THUNDERSTORMS TO BE QUITE ACTIVE OVER INTERIOR AND EASTERN SECTIONS THIS AFTERNOON. BRIEF IFR CONDITIONS ALONG WITH WIND GUSTS IN EXCESS OF 35 KT AND SMALL HAIL POSSIBLE WITH THIS ACTIVITY WHICH COULD LINGER INTO THE EARLY EVENING HOURS. /MOLLEDA .PREVIOUS DISCUSSION... .DISCUSSION... WATER VAPOR IMAGERY INDICATES THAT THE WEAK MID-LEVEL SHORTWAVE TROUGH RESPONSIBLE FOR EVENING CONVECTION ACROSS THE NORTHEAST PORTION OF THE FORECAST AREA CONTINUES TO MOVE AWAY FROM THE REGION...WITH GENERALLY QUIET WEATHER AT THIS TIME. DESPITE LIGHT WINDS AND NEARLY SATURATED LOW-LEVEL CONDITIONS...THICK MID/HIGH LEVEL DEBRIS CLOUD COVER HAS INHIBITED THE FORMATION OF DENSE FOG...BUT WILL CONTINUE TO MONITOR VISIBILITY TRENDS THROUGH THE MORNING HOURS. SHORT TERM MODELS CONTINUE TO POINT TOWARD ANOTHER VERY ACTIVE DAY OF CONVECTION SHAPING UP TODAY...AS REMNANTS OF WEAK COLD FRONT WILL MAINTAIN LIGHT GRADIENT FLOW ACROSS THE AREA...AND GLOBAL MODELS SUGGEST THAT ANOTHER MID-LEVEL VORT MAX EMBEDDED IN SOUTHWEST FLOW ALOFT WILL BE APPROACHING THE AREA THIS AFTERNOON. GUIDANCE FROM THE WRF-NMM AND SREF...AS WELL AS THE LOCAL WRF...SUGGEST THAT CONVECTION WILL DEVELOP BY EARLY AFTERNOON ALONG THE ATLANTIC COAST SEA BREEZE...WITH SOUTH- SOUTHWEST ORIENTED STEERING FLOW WARRANTING HIGH POPS FOR EASTERN HALF OF THE FORECAST AREA...INCLUDING THE NEAR SHORE COASTAL WATERS. WILL INCREASE POPS INTO THE LIKELY CATEGORY FOR THIS REGION...AND FORECAST HIGH CHANCE POPS ELSEWHERE...AS POTENTIAL WILL ALSO EXIST FOR A SEA BREEZE ALONG THE GULF COAST. IT STILL APPEARS THAT CYCLOGENESIS WILL BE UNDERWAY ALONG COASTAL FRONT ACROSS SOUTHEAST TEXAS THIS EVENING...IN RESPONSE TO SHARPENING UPPER TROUGH MOVING ACROSS TEXAS. AS THIS OCCURS... REMNANTS OF LINGERING FRONTAL BOUNDARY WILL SURGE RAPIDLY NORTHWESTWARD...AND FOR THIS REASON WILL MAINTAIN HIGHEST EVENING POPS ACROSS THE NORTH. VERY WARM AND MUGGY BUT DRY CONDITIONS ARE STILL EXPECTED FROM THURSDAY NIGHT THROUGH FRIDAY NIGHT...AS SOUTHEAST FLOW INCREASES DOWNSTREAM FROM INTENSIFYING GULF COAST CYCLONE. RAIN CHANCES WILL INCREASE ONCE AGAIN ON SATURDAY MORNING...AS A MUCH STRONGER COLD FRONT ASSOCIATED WITH UPPER TROUGH DIGGING ACROSS THE SOUTHEASTERN U.S. SURGES INTO THE REGION. GUIDANCE IS IN FAIRLY GOOD AGREEMENT ON THE COLD FRONT REACHING THE NORTHWEST COUNTIES BY EARLY/MID-MORNING SATURDAY... AND SWEEPING ACROSS THE REMAINDER OF THE AREA THROUGH THE AFTERNOON. EXPECT SCATTERED SHOWERS/STORMS TO ACCOMPANY THE FRONTAL PASSAGE...WITH ACTIVITY SHIFTING OFFSHORE BY LATE AFTERNOON. FORECASTED VALUES OF DEEP-LAYER SHEAR AND INSTABILITY STILL APPEAR TO SUPPORT A HIGHER THREAT FOR ORGANIZED/SEVERE CONVECTION WITH THIS SYSTEM...IF LOW-LEVEL FLOW CAN REMAIN SUFFICIENTLY BACKED PRIOR TO FRONTAL PASSAGE...AND THIS THREAT WILL HAVE TO BE REFINED AS THE EVENT APPROACHES. A MIXTURE OF PACIFIC AND MODIFIED ARCTIC AIR WILL BE SPREADING RAPIDLY OVER THE AREA AT THE BEGINNING OF THE EXTENDED FORECAST PERIOD...WITH TEMPERATURES ON SUNDAY MORNING POSSIBLY FALLING INTO THE UPPER 30S ACROSS THE NORTHWEST INTERIOR COUNTIES. EXPECT VERY PLEASANT WEATHER FOR THE SECOND HALF OF THE WEEKEND...WITH MORE SEASONAL TEMPERATURE/DEW POINTS EXPECTED. SURFACE HIGH PRESSURE WILL SLOWLY SLIDE OFF THE EAST COAST OF THE U.S. DURING THE REMAINDER OF THE EXTENDED FORECAST...WITH BROAD WEST/SOUTHWEST FLOW ALOFT. ASIDE FROM INCREASING CLOUD COVER AND ISOLATED EAST- FLOW REGIME SHOWERS...QUIET WEATHER WILL CONTINUE THROUGH THE END OF NEXT WEEK. && .AVIATION... WIDESPREAD MID LEVEL CLOUDS CONTINUE TO OVERSPREAD ALL TERMINALS EARLY THIS MORNING WITH CIGS RUNNING 8-12K FEET. DESPITE MID CLOUDS, PATCHY FOG OR HAZE IS POSSIBLE THROUGH JUST AFTER SUNRISE. MID CLOUDS SHOULD BREAK SOME THIS MORNING, ALLOWING HEATING AND INITIAL LIGHT/VARIABLE WINDS TO TREND TOWARDS SEA BREEZES ON BOTH COASTS...POSSIBLY BY LATE MORNING EASTERN TERMINALS AND EARLY AFTERNOON AT KAPF. CONVERGENCE WITH THE SEA BREEZES SHOULD ALLOW FOR TSRA TO DEVELOP MUCH OF THE AFTERNOON HOURS...WITH ANY STORM CAPABLE OF BRIEF IFR CONDITIONS OR SLIGHTLY ABOVE. && .MARINE... THERE ARE NO IMMEDIATE MARINE HAZARDS ASIDE FROM THOSE ASSOCIATED WITH THUNDERSTORMS THIS AFTERNOON. VERY STRONG SOUTH TO SOUTHEAST FLOW WILL DEVELOP ACROSS ALL COASTAL WATERS BY FRIDAY MORNING...AS SURFACE LOW PRESSURE DEVELOPS ACROSS THE SOUTHEASTERN U.S. WINDS WILL APPROACH SCA CRITERIA OVER ALL COASTAL WATERS... WITH SEAS EXPECTED TO RISE INTO THE 4-6 FOOT RANGE. WINDS WILL REMAIN IN THE 15-20 KNOT RANGE AS THEY VEER TO SOUTHWEST AND EVENTUALLY NORTHWEST WITH THE PASSAGE OF A STRONG COLD FRONT ON SATURDAY. EXPECT LIGHTER NORTHEAST FLOW AND GRADUALLY SUBSIDING SEAS THROUGH THE REMAINDER OF THE EXTENDED FORECAST PERIOD. && .FIRE WEATHER... MINIMUM AFTERNOON RELATIVE HUMIDITY VALUES WILL REMAIN SUFFICIENTLY HIGH TO PREVENT A SIGNIFICANT FIRE WEATHER THREAT THROUGH THIS WEEKEND. HOWEVER...AN ENHANCED FIRE WEATHER THREAT WILL LIKELY DEVELOP OVER MUCH OF SOUTH FLORIDA ON SUNDAY...AND ACROSS THE NORTHWEST INTERIOR COUNTIES ONCE AGAIN ON MONDAY AND TUESDAY...FOLLOWING THE PASSAGE OF A STRONG COLD FRONT ON SATURDAY. && .PRELIMINARY POINT TEMPS/POPS...
