AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 340 PM EDT MON JUN 23 2008 .SYNOPSIS... A SERIES OF FAST MOVING UPPER LEVEL DISTURBANCES WILL BRING SMALL CHANCES FOR PRIMARILY AFTERNOON AND EVENING THUNDERSTORMS FOR MUCH OF THE WEEK. TEMPERATURES WILL BE NEAR NORMAL WITH HIGHS IN THE 70S TO LOWER 80S AND OVERNIGHT LOWS GENERALLY IN THE 50S. && .NEAR TERM /UNTIL 6 AM TUESDAY MORNING/... AS OF 325 PM EDT MONDAY...MAIN FORECAST ISSUE FOR OVERNIGHT WILL BE CONVECTION EARLY THIS EVENING. SO FAR WEVE SEEN TSTMS FLARE UP MAINLY IN VERMONT WERE INSTABILITY HAS BEEN A LITTLE HIGHER. NO REPORTS OF HAIL OR STRONG WINDS YET...BUT THE STORMS ARE EFFICIENT RAIN PRODUCERS WITH RADAR ESTIMATES SHOWING A FEW LOCATIONS WITH OVER 1 OF RAIN FALLEN IN LESS THAN AN HOUR. BEEN QUIET OVER MOST OF NRN NY AS INSTABILITY A BIT LESS (CAPE VALUES ROUGHLY 700 VS 1500) THAN ACROSS CHAMP VALLEY/NRN VT. PERHAPS A BIT OF DOWNWIND OF LAKE ONTARIO STABILIZATION GOING ON. HOWEVER LOOKS LIKE CONVECTION OVER ONTARIO ABOUT TO SLIDE INTO THE ST LAWRENCE VALLEY. WILL MAINTAIN LIKELY POPS FOR TSHWRS EARLY THIS EVENING AREA WIDE AND KEEP WORDING FOR HVY RAINS AND GUSTY WINDS. TOOK OUT MENTION OF HAIL AS THAT SEEMS TO BE LOWER THREAT. EXPECT ACTIVITY TO PRETTY MUCH WIND DOWN BY 01Z...IF NOT A LITTLE BIT EARLIER. AFTER THAT WILL KEEP SMALL POPS IN FORECAST BUT FOR THE MOST PART IT WILL BE DRY. SKIES SHOULD BE CLEARING OUT AFTER MIDNIGHT AND MAKING FOR PATCHY FOG DEVELOPMENT...ESPECIALLY WHERE IT RAINS THIS AFTERNOON. && .SHORT TERM /6 AM TUESDAY MORNING THROUGH WEDNESDAY NIGHT/... AS OF 325 PM EDT MONDAY...UPPER TROF THAT HAS HELPED TO INITIATE TODAYS CONVECTION WILL BE SLIDING ACROSS THE FCST AREA TOMORROW AND SHOULD BE A FOCUS FOR MORE SHWRS/TSTMS (JUST LOOK WEST ACROSS ERN GREAT LAKES AND ONTARIO FOR PROOF). TIMING OF THE TROF PASSAGE LOOKS TO BE DURING THE MORNING ACROSS THE ST LAWRENCE VALLEY...TO EARLY AFTERNOON IN CHAMPLAIN VALLEY AND LATE AFTN ACROSS ERN VT. THUS OVERALL THE HIGHEST COVERAGE SHOULD BE ACROSS VT. HAVE TRIED TO TREND POP GRIDS TO SHOW THIS...NOT SURE HOW GOOD I DID THOUGH. WHATEVER PRECIP WE SEE TOMORROW SHOULD END BEFORE SUNSET...LEADING TO A QUIET TUES NITE. IN THE WAKE OF THE UPPER TROF...WELL HAVE A FEW DAYS OF LEAST OF A NORTHWEST FLOW PATTERN ALOFT. THIS CAN BE A PROBLEMATIC UH-OH PATTERN FOR US AS WEAK DISTURBANCES CAN RACE ALONG IN THE FLOW AND SPARK THUNDERSTORMS...AND IF THEY ARE TIMED FOR THE PEAK HEATING OF THE DAY THEN WE REALLY START TO WORRY. FOR BETTER OR WORSE...MODELS ARE HINTING THAT A SHORTWAVE WILL BE PASSING ACROSS THE CWA WEDNESDAY AFTERNOON. HAVE PAINTED LOW CHANCE POPS FOR MAINLY THE NRN HALF OF THE AREA. BEYOND THIS POINT...FCST CONFIDENCE STARTS TO DECREASE AS THAT FAST FLOW MAKES IT HARD TO TIME THINGS AND MODELS MAY BE PRONE TO DEVELOPING LITTLE SYSTEMS VIA CONVECTIVE FEEDBACK. THAT SAID...KEPT IN SMALL POPS FOR NRN HALF OF AREA WEDNESDAY NIGHT AS ALL MODELS ARE HINTING THAT ANOTHER DISTURBANCE CAPABLE OF SPARKING SHWR/TSTMS MAY ARRIVE HERE LATE WEDNESDAY NIGHT. DESPITE THE PESSIMISTIC SOUNDING FORECAST...IT REALLY WONT BE ALL THAT STORMY. MUCH OF THE DAYS WILL REMAIN RAIN FREE AND ANY TSTMS WILL BE SCATTERED IN NATURE...MEANING SOME FOLKS GET WET BUT MOST OTHERS DONT. STILL IF YOU ARE PLANNING OUTDOOR ACTIVITIES YOU WILL NEED TO PAY CLOSE ATTENTION TO FCSTS. TEMPERATURES WILL BE NEAR NORMAL AS WELL. && .LONG TERM /THURSDAY THROUGH MONDAY/... AS OF 303 PM EDT MONDAY...CONFIDENCE CONTINUES TO SINK AS YOU GO FARTHER INTO THE EXTENDED. STILL NORTHWEST FLOW THRU FRIDAY SO GOTTA KEEP IN SOME CHANCE OF PRECIP. AFTER THAT THE GFS AND ECMWF ARE HINTING THAT YET ANOTHER UPPER LOW WILL DEVELOP OVER THE GREAT LAKES PUTTING US INTO MOISTURE SOUTHWEST FLOW AND INCREASED PRECIP CHANCES AND COVERAGE. FOLLOWED GMOS WHICH THAT FAR OUT TRENDS STRONGLY TOWARD CLIMATOLOGY...MEANING P/M CLDY SKIES AND 30-40% POPS EACH DAY. ALTHOUGH DETAILS ARE FAR FROM CLEAR...IT DOES LOOK LIKE A GENERALLY STORMY AND UNSETTLED PATTERN WILL CONTINUE THRU THE WEEKEND IF NOT BEYOND THAT. && .AVIATION /19Z MONDAY THROUGH SATURDAY/... THROUGH 18Z TUESDAY...AN APPROACHING UPPER LEVEL TROUGH OF LOW PRESSURE AND ITS ASSOCIATED COLD FRONT WILL HELP TO DEVELOP SHOWERS AND THUNDERSTORMS THIS AFTERNOON...SOME MAYBE SEVERE. ANY OF THE THUNDERSTORMS THIS AFTERNOON WILL HAVE THE POTENTIAL TO PRODUCE GUSTY WINDS...HAIL...AND HEAVY DOWNPOURS. THIS THUNDERSTORM THREAT WILL LAST THROUGH ABOUT 02Z AND THEN STORMS SHOULD COME TO AN END AND A RETURN TO VFR CONDITIONS IS EXPECTED THROUGH THE REMAINDER OF THE NIGHT. THE COLD FRONT WILL MOVE THROUGH THE AREA FROM 12Z TUESDAY IN THE NORTHERN NEW YORK AND 18Z EASTWARD...WITH A WIND SHIFT FROM SOUTH AND SOUTHWEST TO WEST AND NORTHWEST EXPECTED. 18Z TUESDAY THROUGH THURSDAY...WEATHER WILL REMAIN UNSETTLED THROUGH THE EXTENDED PERIOD AS THE UPPER TROUGH PUSHES THROUGH THE NORTH COUNTRY ON TUESDAY MORNING. UPPER FLOW THEN TURNS ZONAL ON WEDNESDAY WITH A SHORT WAVE RIDGE BUILDING OVER THE AREA. THEN ANOTHER SHORTWAVE WILL APPROACH THE AREA BY THURSDAY. CONDITIONS SHOULD REMAIN VFR...THOUGH LOCALLY DOWN TO MVFR IN ANY ISOLATED SHOWER. && .BTV WATCHES/WARNINGS/ADVISORIES... VT...NONE. NY...NONE. && SYNOPSIS...NASH NEAR TERM...NASH SHORT TERM...NASH LONG TERM...NASH AVIATION...EVENSON/LAHIFF
