The episode as NWS BTV wrote it up.

AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 227 PM EDT TUE JUN 17 2008 .SYNOPSIS... UNSETTLED WEATHER WILL CONTINUE THE NEXT COUPLE OF DAYS ACROSS THE REGION AS WE WILL BE UNDER THE INFLUENCE OF A SLOW MOVING UPPER LEVEL LOW PRESSURE SYSTEM. EACH DAY WILL FEATURE PRIMARILY SHOWERS DURING THE LATE MORNING AND AFTERNOON...WHICH WILL TEND TO DIMINISH DURING THE EARLY EVENING HOURS. THERE IS A THREAT FOR SOME THUNDERSTORMS THIS AFTERNOON TO PRODUCE HAIL...ESPECIALLY ACROSS VERMONT. && .NEAR TERM /THROUGH TONIGHT/... AS OF 1000 AM EDT TUESDAY...PREVIOUS FORECAST PRETTY MUCH ON TRACK. ALREADY SEEING DEVELOPMENT OF SHWRS AND ISOL TSTMS ACROSS ERN NEW YORK. EXPECT THIS TREND TO CONTINUE WITH THE RADAR RAPIDLY FILLING IN EVEN BY NOON. MESOANALYSIS SHOWS CAPES OF 500-1000J/KG FROM THE CHAMPLAIN VALLEY EASTWARD AND THIS IS WHERE THE PRIMARY ACTION WILL BE. QUITE CHILLY ALOFT...AND WET BULB ZERO DOWN AROUND 8000-8500FT. THIS INDICATES THAT CONVECTION WILL RATHER EASILY PRODUCE HAIL. NOT A LOT OF WINDS ALOFT...SO NOT EXPECTING MUCH MORE THAN 25 OR 30KTS OF WIND GUSTS WITH ANY STRONGER STORMS. LOOKS LIKE THE NORTHEAST KINGDOM WILL HAVE THE HIGHEST RISK OF ANY OF THESE STRONG STORMS AS THEY WILL HAVE THE WARMEST TEMPS AND MOST DAYTIME HEATING. CURRENTLY MOVING ACROSS THE ST LAWRENCE VALLEY IS THE LEADING EDGE OF STRONGER LOW/MID LEVEL CAA. THERE ARE SOME LIGHT SHOWERS ALONG WITH A BAND OF CLOUDS WITH THIS FEATURE. BEHIND THIS SFC TEMPS ARE IN THE 50S WITH DEWPOINTS DROPPING INTO THE 40S...THUS THREAT FOR CONVECTION QUITE LOW WEST OF THIS FRONT. SHOULD BE CROSSING INTO THE CHAMPLAIN VALLEY ABOUT 17Z AND THEN INTO THE NORTHEAST KINGDOM BY LATE AFTERNOON. MAY NEED TO DO AN UPDATE IN A FEW HOURS TO REMOVE TSTM RISK FROM PARTS OF THE AREA...BUT WILL PLAY THAT BY EAR. FOR THE TIME BEING NOT PLANNING ANY CHANGES. && .SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/... AS OF 230 AM EDT TUESDAY...RATHER REMARKABLE UPR LOW EXPECTED TO PROGRESS SLOWLY EWD ACROSS NRN CWA BETWEEN 18Z WED AND 00Z FRI BEFORE LIFTING NEWD INTO SRN QUEBEC THURSDAY NIGHT INTO FRIDAY. CORE OF COLDEST 500MB TEMPERATURES CENTERED OVER NRN SECTIONS OF THE NORTH COUNTRY AT 12Z THURSDAY AT -22C TO -23C THIS WILL CONTINUE TO LEAD TO DAYTIME SHOWER DEVELOPMENT WEDNESDAY/THURSDAY...PEAKING IN THE LATE AFTN/EARLY EVENING AND LESSENING DURING THE OVERNIGHT HRS. WILL NEED TO CARRY MENTION OF SHOWERS EACH PERIOD...WITH HIGHEST POPS NEAR DIURNAL HEATING MAX. WITH HIGH MID-JUNE SUN ANGLE CAN/T RULE OUT JUST ENOUGH CAPE TO YIELD A FEW AFTN/EVE T-STORMS...THOUGH THREAT LOOKS LESS THAN TUESDAY. WILL KEEP TSTM MENTION TO SLIGHT CHC ON WEDNESDAY AND LEAVE OUT FOR NOW ON THURSDAY. HIGH TEMPERATURES WEDNESDAY AND THURSDAY WILL ONLY BE IN THE MID-UPR 60S IN THE VALLEYS AND UPR 50S TO LOW 60S AT ELEVATIONS OF 1-2KFT. SFC WINDS WILL CONTINUE TO BE LIGHT THRU THE SHORT-TERM PERIOD WITH WEAK SEA-LVL PRES FIELD OVER THE REGION. && .LONG TERM /FRIDAY THROUGH MONDAY/... AS OF 230 AM EDT TUESDAY...LITTLE OVERALL CHANGE IN LATEST 00Z GFS SOLN WITH MID-UPR TROPOSPHERIC TROUGH PREVAILING ACROSS THE ERN CONUS EVEN AS UPR LOW LIFTS OUT OF OUR AREA THURSDAY NIGHT INTO FRIDAY. THE 16/12Z ECMWF SHOWED A DIFFERENT SOLN...WITH A MORE PROGRESSIVE WLY 500MB FLOW DEVELOPING IN THE WAKE OF THE UPR LOW FRIDAY AND SATURDAY...WITH A SHORTWAVE TROUGH AFFECTING THE AREA ON SUNDAY/SUNDAY NIGHT. THIS MIGHT MEAN A DRIER SOLN FRIDAY/SATURDAY...BUT HAS LITTLE SUPPORT AMONG THE GFS OR GFS ENSEMBLE SOLNS. IT/S FAIR TO SAY THAT CONFIDENCE IS LOWER THAN AVERAGE IN THE EXTENDED FCST FOLLOWING THE UPR LOW IN THE SHORT TERM. WITH MODEL SOLN SPREAD WILL STAY CLOSER TO OP 00Z GFS SOLN FOR NOW...WHICH ALLOWS FOR AFTN CHANCES OF SHOWERS AND THUNDERSTORMS AND TEMPERATURES GRADUALLY RECOVERING CLOSER TO SEASONAL NORMS. THIS IS ALSO CLOSER TO PREVIOUS FCST AND PREFER CONTINUITY ATTM. && .AVIATION /18Z TUESDAY THROUGH SUNDAY/... THROUGH 18Z WEDNESDAY...MAINLY VFR CONDITIONS THROUGH THIS EVENING. SCT TSRA AND SHRA COULD BRIEFLY BRING MVFR CIGS. ISLD IFR VSBYS UNDER THE HEAVIER SHOWERS BUT HELD OUT OF TAFS DUE TO LOW POINT PROBABILITY. WEST TO SOUTHWEST WINDS BRINGING IN SLIGHTLY LOWER DEWPOINTS AND DRIER AIR SO WEST OF KBTV ONLY -SHRA EXPECTED. EXPECT CONVECTION TO DIE OUT FROM WEST TO EAST AFTER SUNSET. CLOUD DEBRIS MAINLY 3500 FT TO 10 THOUSAND FEET EXPECTED OVERNIGHT. STATISTICAL GUIDANCE SHOWING SOME MVFR CIGS POSSIBLE LATE AT NIGHT ESP NRN NY. 18Z WEDNESDAY THROUGH SUNDAY...VFR...LOCAL MVFR CIGS EXPECTED THROUGH THE PERIOD...THOUGH VERY BRIEF AND LOCAL IFR VSBY CONDITIONS WILL BE POSSIBLE IN ANY HEAVY SHOWERS. AN UPPER LEVEL LOW SETTLES OVER THE NORTH COUNTRY THURSDAY THEN LIFTS NE BY THE WEEKEND. AS A RESULT...EXPECT ABUNDANT CLOUD COVER AND MAINLY AFTERNOON AND EVENING SHOWERS THROUGH SATURDAY. CONDITIONS SHOULD SLOWLY IMPROVE FRIDAY INTO SATURDAY AS THE LOW FINALLY MOVES AWAY FROM THE REGION. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...NONE.
