AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
339 AM EDT TUE MAY 27 2014
.SYNOPSIS...
ADDITIONAL SHOWERS ARE EXPECTED DURING THE DAY TUESDAY AS A BACKDOOR 
COLD FRONT PUSHES SOUTHWESTWARD FROM NORTHERN MAINE AND THE ST. 
LAWRENCE SEAWAY. THE WARMEST TEMPERATURES TODAY WILL BE FOUND ACROSS 
WESTERN VERMONT AND PORTIONS OF NORTHERN NEW YORK AWAY FROM THE 
IMMEDIATE ST. LAWRENCE VALLEY AND AWAY FROM THE APPROACHING COLD
FRONT. A FEW STRONG THUNDERSTORMS WILL BE POSSIBLE THIS AFTERNOON
AND EARLY THIS EVENING ACROSS NORTHERN NEW YORK AND WESTERN
VERMONT. SMALL HAIL AND GUSTY WINDS CAN BE EXPECTED WITH THE
STRONGER STORMS. THE BACKDOOR COLD FRONT RESULTS IN A COOLER MARITIME
AIR MASS ACROSS THE ENTIRE NORTH COUNTRY ON WEDNESDAY...BUT WILL
ALSO PROVIDE A BREAK FROM THE SHOWERY CONDITIONS OF THE PAST FEW
DAYS. HIGH PRESSURE PREVAILS THROUGH THURSDAY WITH DRY CONDITIONS.
A SURFACE AND UPPER LEVEL TROUGH APPROACHING FROM SOUTHWESTERN
QUEBEC AND SOUTHEASTERN ONTARIO THURSDAY NIGHT INTO FRIDAY WILL
BRING ADDITIONAL SCATTERED SHOWERS ACROSS THE NORTH COUNTRY...WITH
A CHANCE OF THUNDERSTORMS FRIDAY AFTERNOON. CONDITIONS WILL TREND
DRIER AND WARMER FOR THE UPCOMING WEEKEND.
&&
.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 321 AM EDT TUESDAY...TEMPERATURE FORECAST IS COMPLICATED BY 
WESTWARD AND SOUTHWESTWARD ADVECTION OF MARITIME POLAR AIR MASS
BACKING IN AT US FROM MAINE AND THE ST. LAWRENCE SEAWAY THIS
AFTERNOON IN THE FORM OF A BACKDOOR COLD FRONT. IT APPEARS BASED
ON 00Z NAM SFC-925MB FORECAST THAT THE BACKDOOR COLD FRONT WILL
REACH THE CT RIVER VALLEY AROUND 18Z...AND THEN CONTINUE TO PUSH
WWD TO ALONG THE SPINE OF THE GREEN MTNS BY 21Z. A CONTINUED
WESTWARD PUSH OF THE MARITIME AIR IN VT WILL BE SLOWED BY
OROGRAPHIC BLOCKING...LIKELY HOLDING OFF UNTIL THE EVENING HRS
ACROSS WRN VT AND THE SRN CHAMPLAIN VALLEY. THUS...WILL LIKELY
SEE A STRONG TEMPERATURE GRADIENT LATER THIS AFTERNOON ACROSS
VT...RANGING FROM THE LOW 60S EAST OF THE GREENS...TO THE UPR
60S/LOW 70S ACROSS THE SRN CHAMPLAIN VLY AND RUTLAND COUNTY.
SIMILAR TEMPERATURE CONTRAST LIKELY TO OCCUR ACROSS NRN NY AND THE
NORTHERN CHAMPLAIN VALLEY AS MARITIME AIR SPILLS SWWD DOWN THE ST.
LAWRENCE VALLEY AND INTO THE NRN CHAMPLAIN VALLEY AND CHAMPLAIN
ISLANDS THIS AFTERNOON ON INCREASING NORTH TO NELY WINDS. WILL SEE
LOWER 70S ACROSS THE ADIRONDACKS AND SWRN ST. LAWRENCE
COUNTY...WHILE TEMPS LIKELY FALL INTO THE MID 60S WITH LOW-LEVEL
COLD ADVECTION ACROSS NRN CLINTON/NRN FRANKLIN/GRAND ISLE AND NRN
ST. LAWRENCE COUNTIES TOWARD MID-LATE AFTERNOON. BTV WILL BE RIGHT
ON THE EDGE OF THIS COLDER AIR MASS...LIKELY REACHING THE LOW 70S
IN THE EARLY AFTN BEFORE DROPPING BACK INTO THE 60S WITH NLY WIND
SHIFT. 
IN AREAS UNAFFECTED BY THE MARITIME AIR MASS...DAYTIME HEATING WILL 
YIELD SURFACE BASED INSTABILITY WITH SBCAPE OF 500-1000 J/KG ACROSS 
WRN VT AND 1000-1500 J/KG ACROSS NRN NY SOUTH OF THE ST. LAWRENCE 
RIVER VALLEY. AT THE SAME TIME...PREVAILING DEEP-LAYER NWLY FLOW 
WILL MAINTAIN MODERATELY STRONG SFC-6KM BULK SHEAR VALUES OF 40-50 
KTS. THUS...IT APPEARS THAT SCATTERED SHOWERS THIS MORNING WILL 
BECOME MORE NUMEROUS DURING THE AFTERNOON WITH EMBEDDED TSTMS 
POSSIBLE ACROSS WRN VT INTO OUR NY ZONES. WILL CARRY CHANCE TSTMS IN 
THESE AREAS...WHILE LEAVING OUT ANY TSTMS FOR NERN/ERN VT WITH 
STABILIZING MARINE AIR MASS ADVECTING IN. BEST COMBINATION OF 
DEEP-LAYER SHEAR AND INSTABILITY IS ACROSS THE SRN ST. LAWRENCE 
COUNTY...PORTIONS OF THE ADIRONDACKS...INTO ADDISON/RUTLAND
COUNTIES IN VERMONT. IN THESE AREAS ORGANIZED AND LONG-LIVED
UPDRAFTS COULD SUPPORT SMALL HAIL AND LOCALLY GUSTY WINDS WITH
STRONGER CORES. WILL INCLUDE THESE STORM ATTRIBUTES IN THE FORECAST
GRIDS FROM KBTV SOUTH AND WESTWARD AS WELL AS A MENTION IN THIS
MORNING/S HWO.
WILL CARRY CHANCE POPS THIS MORNING...AND RAMP TO 50-80% POPS DURING
THE MID-LATE AFTN HRS ACROSS NRN NY INTO RUTLAND COUNTY VT. WINDS
WILL BE RATHER VARIABLE...TURNING ELY THIS AFTN EAST OF THE GREEN
MTNS AND NELY IN THE ST. LAWRENCE RIVER VALLEY. WINDS WILL TURN
NORTHERLY IN THE IMMEDIATE CHAMPLAIN VALLEY AS COOLER AIR MASS
ADVECTS SOUTH IN THE VALLEY. ELSEWHERE...ANTICIPATE VARIABLE WIND
CONDITIONS BASED ON EXACT POSITION OF BACKDOOR COLD FRONT AND
OWING TO CONVECTIVE OUTFLOWS IN AFFECTED LOCATIONS THIS AFTERNOON. 
&&
.SHORT TERM /8 PM THIS EVENING THROUGH THURSDAY/...
AS OF 321 AM EDT TUESDAY...LINGERING CONVECTIVE STORMS ACROSS NRN
NY INTO SWRN VT WILL DIMINISH IN COVERAGE AND INTENSITY EARLY THIS
EVENING WITH LOSS OF DAYTIME HEATING...AND AS COOLER MARITIME AIR
MASS EVENTUALLY PUSHES SOUTH AND WESTWARD ACROSS THE REMAINDER OF
OUR FORECAST AREA. A FEW SHOWERS COULD CONTINUED THROUGH THE
OVERNIGHT PERIOD...ESPECIALLY ACROSS CENTRAL/S-CENTRAL VT.
ABUNDANT LOW CLOUDS ARE ALSO EXPECTED ASSOCIATED WITH MARINE
AIR...WITH PATCHY DRIZZLE POSSIBLE EAST OF THE GREEN MTNS.
OVERNIGHT LOWS WILL RANGE FROM THE MID 40S EAST OF THE GREENS TO
THE UPR 40S/LOWER 50S ELSEWHERE. SFC WINDS WILL BE CHANNELED DOWN
THE ST. LAWRENCE VALLEY FROM THE NE AROUND 10 KTS MUCH OF TONIGHT.
LIKEWISE...COOLER AIR MASS WILL PUSH THROUGH THE GREEN MTN
GAPS/PASSES WITH LOCALLY GUSTY E/SE WINDS ALONG THE WRN SLOPES AT
TIMES OVERNIGHT (UP TO 25 MPH). 
ON WEDNESDAY...SFC RIDGE NOSES SWWD FROM ME/NH INTO VERMONT WITH
GRADUALLY LESSENING OF LOW STRATUS/STRATOCU WITH DAYTIME HEATING
AND MIXING. SHOULD BE PARTLY SUNNY MOST LOCATIONS FOR THE AFTN
HOURS. IT WILL BE A RELATIVELY COOL DAY WITH PREVAILING MARITIME
AIR MASS IN PLACE...WITH HIGHS MAINLY IN THE MID 60S (5-8F BELOW
NORMAL). WINDS WILL BE LIGHT AND VARIABLE.
CONTINUED DRY WEDNESDAY NIGHT AND THURSDAY WITH SFC RIDGE IN
PLACE. HIGH CENTER SHIFTS EWD INTO THE GULF OF MAINE ALLOWING FOR
DEVELOPMENT OF LIGHT SOUTHERLY WINDS FOR THE DAYLIGHT HRS
THURSDAY. THIS WILL ALLOW AIR MASS TO MODERATE A BIT WITH HIGHS
BACK INTO THE UPR 60S TO LOWER 70S. 
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
AS OF 321 AM EDT TUESDAY...THURSDAY NGT AND FRIDAY WILL BRING AN 
INCREASING THREAT OF SHOWERS AS UPPER LVL TROUGH MOVES OVER THE 
NORTH COUNTRY. GFS INDICATING SOME INSTABILITY DURING THE DAY 
FRIDAY...SO HAVE INCLUDED CHC TS. UPPER LVL TROUGH AND ASSOCIATED 
VORTICITY WILL SHIFT SOUTH AND EAST OUT OF THE AREA ON SATURDAY...SO 
HAVE LOW CHC FOR RESIDUAL SHOWERS OVER VT. SATURDAY NGT THROUGH 
SUNDAY NGT...HIGH PRESSURE AT THE SFC WILL RESIDE OVER THE REGION 
WHILE UPPER LVL RIDGING WILL BUILD IN...RESULTING IN DRY AND MOSTLY 
CLEAR CONDITIONS. SFC RIDGE SLIDES TO THE SE SUNDAY NGT...PUTTING 
THE NORTH COUNTRY IN SW FLOW...AHEAD OF A COLD FRONT APPROACHES FROM 
THE NW. CLOUDS WILL SPREAD OVER THE REGION MONDAY...WITH INCREASING 
THREAT OF SHOWERS ASSOCIATED WITH THE COLD FRONT. MODELS DIVERGE ON 
EVOLUTION OF THIS SYSTEM...AS GFS KEEPS THE UPPER RIDGE IN PLACE 
LONGER AND AFOREMENTIONED COLD FRONT WASHING OUT OVER THE AREA. 
ECMWF KEEPS THE FRONT STRONGER WITH UPPER VORT LINING UP WELL WITH 
SAID FRONT. BOTH MODELS HAVE AFFECTS OF FRONT ENDING MONDAY NGT WITH 
BRIEF PERIOD OF DRY WEATHER ON TUESDAY BEFORE ANOTHER SYSTEM 
ATTEMPTS TO MOVE IN FROM THE GREAT LAKES REGION.
TEMPERATURES THROUGHOUT THE PERIOD WILL BE NEAR TO SLIGHTLY ABOVE 
NORMAL WITH MAX TEMPS IN THE 60S MTNS AND L/M70S VALLEYS. MIN TEMPS 
WILL BE IN THE 40S MTNS AND L/M50S VALLEYS.
&&
.AVIATION /08Z TUESDAY THROUGH SATURDAY/...
THROUGH 06Z WEDNESDAY...GENERALLY VFR CONDITIONS WILL SEE PSBL
MVFR VSBYS THIS MORNING AS MOST SITES HAVE 3 DEGREE OR LESS T/TD
SPREAD. VRB LGT WINDS ACROSS MOST OF THE AREA WITH MID LVL CLOUDS
DIMINISHING IN AREAL COVERAGE WILL AID IN CHC FOR MVFR CONDITIONS
TO DEVELOP MAINLY BTWN 08Z AND 11Z. HAVE INCLUDED TEMPO WITH
EXCEPTION OF KRUT DUE TO CONSISTENT DRAINAGE FLOW AROUND 7 KTS.
AFTER SUNRISE...BACKDOOR COLD FRONT WILL TRAVERSE OVER THE REGION
FROM NE TO SW...TRIGGERING SOME SHOWERS AND PSBL TS AFTER 15Z.
BEST INSTABILITY LOOKS TO BE SOUTH IN WARM SECTOR...MEANING KRUT
WILL HAVE BEST CHANCE OF SEEING TS WEDNESDAY AFTN. PSBL MVFR/IFR
VSBYS IN STEADIER...HEAVIER RAIN. OTHERWISE MOSTLY VFR CONDITIONS
WITH WINDS MORE VARIABLE AT KRUT/KMSS/KSLK AND KMPV WITH NORTH
WINDS 4-8 KTS EXPECTED IN THE CPV.
SHOWERS AND ANY TS WILL DIMINISH AFTER SUNSET...WITH WINDS BCMG 5
KTS OR LESS...PSBLY LEADING TO BR/FG DEVELOPMENT IN AREAS THAT
RECEIVE RAINFALL DURING THE DAY.
OUTLOOK 06Z WEDNESDAY THROUGH SATURDAY...
06Z WEDNESDAY THRU 12Z WEDNESDAY...VRB CONDITIONS WITH REMNANT
MVFR/IFR SHOWERS DISSIPATING. SOME MVFR/IFR FG/BR DEVELOPMENT
PSBL ESP AT KSLK AND KMPV.
12Z WEDNESDAY ONWARD...MAINLY VFR CONDITIONS UNDER HIGH PRESSURE
WED-THU. AN UPPER LEVEL TROUGH MOVING IN FROM SERN CANADA WILL
BRING SCATTERED SHOWERS THURSDAY NIGHT AND FRIDAY...WITH
INTERVALS OF MVFR CONDITIONS POSSIBLE.
