AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE BURLINGTON VT 736 PM EDT SUN JUN 22 2008 .SYNOPSIS... A WEAK AREA OF LOW PRESSURE AND A SOUTHWEST FLOW OF MILD AND RELATIVELY HUMID AIR WILL CONTINUE TO BRING A THREAT OF SHOWERS AND THUNDERSTORMS TO THE REGION THROUGH TUESDAY. HIGH PRESSURE WILL REDUCE THE THREAT OF PRECIPITATION MID WEEK BEFORE MORE UNSETTLE WEATHER APPROACHES NEXT WEEKEND. TEMPERATURES WILL BE NEAR SEASON AVERAGES. && .NEAR TERM /UNTIL 6 AM MONDAY MORNING/... AS OF 418 PM EDT SUNDAY...INITIAL UPPER SUPPORT FROM A SHORT WAVE TROF LIFTED NORTH INTO CANADA TODAY AND LEFT LOTS OF CLOUDS AND RAIN COOLED AIR. THE AIRMASS WILL RECOVER SOMEWHAT THIS AFTERNOON EVENING WITH SOME BREAKS THAT HAVE DEVELOPED IN THE CLOUD COVER. ALBANY 18Z SOUNDING SHOWS CONVECTIVE TEMPERATURE IN THE LOWER 70S AND CAPE VALUES IN THE 1500-2000 J/KG RANGE. WITH AN UPPER LEVEL JET AND ASSOCIATED DIFFLUENCE MOVING OVER THE AREA THIS EVENING...SFC DEW POINTS IN THE UPPER 50S TO LOWER 60S AND CAPE VALUES OF 1000 J/KG...0-6 KM BULK SHEAR INCREASING FROM NEAR 30 KTS TO 45 KTS EARLY TONIGHT...SOME BOWING OF STORMS IS STILL POSSIBLE. OTHER THREAT IS SOME HEAVY RAINFALL...WITH PRECIPITABLE WATER VALUES OF 1.40 AND LOW LEVEL AND UPPER LEVEL FLOW PARALLEL COULD BE SOME TRAINING OF ECHOES ESPECIALLY SOUTH AND EAST. WILL CONTINUE MENTION GUSTY WINDS...SMALL HAIL...AND HEAVY DOWNPOURS WITH THE THUNDERSTORMS THIS EVENING BUT THINK THIS THREAT WILL BE ISOLATED. THE SHOWERS AND STORMS WILL DECREASE IN AREAL COVERAGE TONIGHT. HOWEVER AS HAPPENED LAST NIGHT...ANOTHER SHORT WAVE TROF MOVING THROUGH THE OHIO VALLEY AND ITS ASSOCIATED LEFTOVER CONVECTION MAY APPROACH THE REGION LATE AT NIGHT/EARLY TOMORROW MORNING. HAVE INTRODUCED PATCHY FOG IN THE FORECAST WITH MANY AREAS EXPERIENCING SOME RAIN TODAY. && .SHORT TERM /6 AM MONDAY MORNING THROUGH TUESDAY/... AS OF 418 PM EDT SUNDAY...UPPER LEVEL TROF WEAKENS WITH RISING HEIGHTS BUT THE AXIS REMAINS WEST OF THE REGION THROUGH MIDDAY TUESDAY BEFORE PROGRESSING EAST. A SIMILAR WEATHER SCENARIO TO TODAY IS EXPECTED FOR MONDAY. SOUTHWEST FLOW AND 0-6KM BULK SHEAR OF AROUND 30 KTS WILL EXIST OVER THE AREA ONCE AGAIN. WITH TEMPERATURES AGAIN IN THE 70S AND DEW POINTS IN THE UPPER 50S TO LOWER 60S...ONCE AGAIN SHOULD SEE CAPE VALUES OF 1000-1500 J/KG DEVELOPING DURING THE AFTERNOON BRINGING ANOTHER ROUND OF THUNDERSTORMS MONDAY AFTERNOON.

THE AREA THEN REMAINS IN A FAIRLY FAST NW FLOW WITH EMBEDDED SHORT WAVES THROUGH THURSDAY LEADING TO GREATER UNCERTAINTY IN THE TIMING OF WEATHER FEATURES BY MIDWEEK. MODELS SUGGEST A MAJOR TROF WILL DEEPEN AND DIG THROUGH THE UPPER GREAT LAKES INTO THE NORTHEAST NEXT WEEKEND BUT AGAIN EXACT TIMING IS UNCERTAIN. RELIED ON GFS ENSEMBLES AND TEMPERATURES AND POPS SIMILAR TO CLIMATOLOGICAL AVERAGES. AT THE SURFACE...DRIER AIR MOVES INTO THE AREA FROM THE NW BY TUESDAY NIGHT. LOOKS LIKE WEDNESDAY MAY BE THE ONLY DAY TO KEEP PRECIPITATION OUT OF THE FORECAST AS HIGH PRESSURE RIDGES MOVES FROM THE OHIO VALLEY TO THE MID ATLANTIC COAST. EVEN SO MODELS SHOW SOME SHOWERS JUST TO THE NORTH BY 00Z THU AND A TROF OR FRONTAL PASSAGE BY THURSDAY. ON FRIDAY A WARM FRONT STARTS TO SPREAD CLOUDS INTO THE REGION WITH A CHANCE OF PRECIP.
