AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
419 AM EDT MON MAY 20 2013
.SYNOPSIS...
AN ACTIVE WEATHER PATTERN IS EXPECTED ACROSS THE NORTH COUNTRY
THIS WEEK...WITH SEVERAL ROUNDS OF RAIN ANTICIPATED WITH A FEW
THUNDERSTORMS POSSIBLE. SHOWERS EXIT THE REGION THIS
MORNING...WITH MAINLY DRY CONDITIONS EXPECTED THIS AFTERNOON AND
TONIGHT...BUT PERIODS OF RAIN RETURN BY TUESDAY AND CONTINUE RIGHT
THROUGH THURSDAY. HIGH PRESSURE AND DRIER CONDITIONS RETURN
THURSDAY NIGHT AND CONTINUE INTO THE WEEKEND.
&&
.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AS OF 418 AM EDT MONDAY...STILL DEALING WITH SOME ISOLATED TO
SCATTERED SHOWERS ACROSS PORTIONS OF THE NORTH COUNTRY THIS
MORNING AS A FRONTAL BOUNDARY MOVING THROUGH THE CWA HAS STALLED
ACROSS OUR NORTHERN TIER COUNTIES. WHILE THIS BOUNDARY WILL
REMAIN STALLED ACROSS THE AREA THROUGH TODAY...OVERALL LOW/MID
LEVEL MOISTURE THINS SO EXPECT SHOWERS TO GENERALLY DISSIPATE AS
SKIES CLEAR TO PARTLY/MOSTLY CLOUDY. STILL A CHANCE FOR A COUPLE
ISOLATED SHOWERS ACROSS CENTRAL AND SOUTHERN VERMONT THIS
AFTERNOON WITH FORECAST SOUNDINGS SHOWING A FEW HUNDRED JOULES OF
CAPE...BUT OVERALL CONDITIONS SHOULD REMAIN FAIRLY DRY. ABOVE
NORMAL TEMPS CONTINUE TODAY WITH MEAN 925MB TEMPS OF +14-18C
SUPPORTING HIGHS IN THE MID TO UPPER 70S.
&&
.SHORT TERM /6 PM THIS EVENING THROUGH WEDNESDAY/...
AS OF 418 AM EDT MONDAY...STALLED FRONTAL BOUNDARY REMAINS OVER
THE NORTH COUNTRY DURING THE SHORT TERM PERIOD AND WILL BE THE
FOCUS FOR PERIODS OF RAIN AND POSSIBLE THUNDERSTORMS THROUGH
WEDNESDAY. LOOKING AT A DRY NIGHT TONIGHT AS AN UPPER LEVEL RIDGE
BUILDS INTO THE REGION...BUT OVERALL CONDITIONS WILL REMAIN FAIRLY
CLOUDY AS LOW/MID LEVEL MOISTURE INCREASES AS SHORTWAVE ENERGY
EJECTING OUT OF A BROAD UPPER TROUGH ACROSS THE CENTRAL CONUS
APPROACHES. IT WILL BE QUITE A MILD NIGHT WITH INCREASING
SOUTHERLY FLOW AND CLOUD COVER CONTRIBUTING TO LOWS ONLY IN THE
50S TO LOCALLY 60S IN THE CHAMPLAIN VALLEY.
A PROLONGED PERIOD OF RAIN BEGINS TUESDAY AND CONTINUES INTO THE
LONG TERM AS SEVERAL WAVES OF LOW PRESSURE MOVE ALONG THE
AFOREMENTIONED FRONTAL ZONE DRAPED FROM THE GREAT LAKES THROUGH
THE BTV CWA AND INTO NH AND MAINE. EXPECTED TO SEE NUMEROUS
SHOWERS THROUGH THE PERIOD WITH CHANCES FOR THUNDERSTORMS DURING
THE AFTERNOON HOURS WITH SURFACE INSTABILITY INCREASING TO OVER
1000 J/KG ACROSS PORTIONS OF THE AREA. A GRADUAL WARMING TREND IS
EXPECTED THROUGH THE PERIOD AS WELL WITH TUESDAY HIGHS IN THE
LOWER TO MID 70S WARMING INTO THE UPPER 70S TO LOWER 80S FOR
WEDNESDAY. MILD OVERNIGHT LOWS ALSO CONTINUE TUESDAY
NIGHT...GENERALLY IN THE 50S TO NEAR 60.
&&
.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
AS OF 344 AM EDT MONDAY...THE LONG-TERM FORECAST PERIOD BEGINS
ACTIVE AS POSITIVE TILT 500MB TROUGH IS EXPECTED ACROSS THE GREAT
LAKES REGION WEDNESDAY NIGHT WITH AN AREA OF LOW PRESSURE ACROSS
SERN ONTARIO ALONG MODERATELY STRONG FRONTAL ZONE STRETCHING WSW-
ENE JUST NORTH OF OUR INTL BORDER. THE OVERALL EVOLUTION THRU THE
EXTENDED IS SIMILAR BETWEEN THE 00Z GFS AND 00Z ECMWF...WITH THE
00Z ECMWF JUST A BIT FASTER.
NORTH COUNTRY BEGINS IN THE WARM SECTOR WEDNESDAY NIGHT WITH SFC LOW 
TRACKING ALONG FRONTAL BNDRY NEAR/JUST NORTH OF THE INTL BORDER. 
SHOULD MAKE FOR A MILD NIGHT WITH LOWS IN THE UPR 50S TO LOWER 60S. 
SHOWERS ARE LIKELY...ESPECIALLY ACROSS NRN VT AND NRN NY WHERE POPS 
ARE NEAR 70 PERCENT. LOWER POPS ACROSS S-CENTRAL VT FURTHER REMOVED 
FROM PROJECTED FRONTAL ZONE. 
DURING THE DAY THURSDAY...FRONTAL ZONE SETTLES SEWD ACROSS THE NORTH 
COUNTRY AS A COLD FRONT...AND SFC LOW TRACKS EWD INTO NH/MAINE. 00Z 
GFS MODEL INDICATES AND THE SYNOPTIC PATTERN SUPPORTS AT LEAST WEAK 
INSTABILITY ALONG THE FRONTAL BNDRY ... SO CARRIED A PERIOD OF 
LIKELY POPS WITH A CHANCE OF TSTMS WITH FRONTAL PASSAGE. HIGHS 
THURSDAY SHOULD GENERALLY BE IN THE MID 70S...WARMEST ACROSS THE CT 
RIVER VALLEY WITH LATER ARRIVAL OF FRONTAL BNDRY BASED ON PRESENT 
INDICATIONS. GRADUALLY CLEARING EXPECTED FOR THURSDAY NIGHT. MAY SEE 
SOME PATCHY FOG GIVEN WET CONDITIONS TUE-THU AND RADIATIONAL COOLING 
THURSDAY NIGHT. LOWS THURSDAY NIGHT MAINLY IN THE 40S...WITH A FEW 
LOWER 50S IN THE CHAMPLAIN VALLEY.  
COOLER AND DRIER CONDITIONS RETURN FRIDAY AS LARGE AREA OF HIGH 
PRESSURE BUILDS SEWD ACROSS ONTARIO AND THE GREAT LAKES REGION 
BRINGING N-NW LOW-LEVEL FLOW TO THE NORTH COUNTRY. ANTICIPATE 
CLEARING SKIES AND GENERALLY PLEASANT CONDITIONS FRIDAY WITH VALLEY 
HIGHS 65-70F. HIGH PRESSURE SHOULD GENERALLY REMAIN IN CONTROL AS IT 
DRIFTS EWD ACROSS THE REGION BRINGING MAINLY DRY WX CONDITIONS THRU 
NEXT WEEKEND. WEAK SHORTWAVE TROUGH IN NW FLOW BRINGS A SLIGHT 
CHANCE OF A SHOWER SATURDAY AFTN OR SATURDAY NIGHT...MAINLY ACROSS 
NRN/NERN VT. DON/T FORESEE ANYTHING SIGNIFICANT IN TERMS OF PRECIP 
AMTS WITH THIS FEATURE GIVEN EXPECTED DRYNESS OF LOW-LEVEL AIR MASS. 
TEMPERATURES WILL REMAIN NEAR TO SLIGHTLY BELOW CLIMATOLOGICAL 
AVERAGES WITH HIGHS IN THE MID-UPR 60S. PROSPECT FOR GOOD 
RADIATIONAL COOLING AT NIGHT SHOULD BRING LOWS LOW-MID 40S FOR MOST 
AREAS...BUT LOCALLY DOWN TO 35F IN THE NRN ADIRONDACKS AND THE MORE 
SHELTERED VALLEY LOCATIONS EAST OF THE GREEN MTNS.
&&
