NATIONAL WEATHER SERVICE BURLINGTON VT
400 AM EDT TUE SEP 1 2015

.SYNOPSIS...
THE UNSEASONABLY WARM AND DRY STRETCH OF WEATHER WILL PERSIST ACROSS
THE NORTH COUNTRY THROUGH THE NEXT 7 DAYS...ASSOCIATED WITH THE
CONTINUED PRESENCE OF A MEAN UPPER LEVEL RIDGE ACROSS THE CENTRAL
AND EASTERN UNITED STATES. HIGH TEMPERATURES THROUGH THE PERIOD WILL
AVERAGE 10 TO 15 DEGREES ABOVE NORMAL. NO SIGNIFICANT RAINFALL IS
EXPECTED...BUT AN UPPER LEVEL DISTURBANCE AND ASSOCIATED SURFACE
TROUGH MAY BRING A FEW SHOWERS AND AN ISOLATED THUNDERSTORM TO THE
REGION WEDNESDAY NIGHT INTO THURSDAY MORNING.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 356 AM EDT TUESDAY...RISING 700-500MB HEIGHTS CONTINUE TODAY
AS A STRONG UPPER RIDGE BUILDS ACROSS NEW YORK AND NEW ENGLAND.
DEEP LAYER RIDGE IN PLACE WILL BRING MOSTLY SUNNY SKIES AND LIGHT
WINDS...WHICH WILL BECOME SOUTH TO SOUTHWEST 5-10 MPH THIS
AFTERNOON. AIR MASS CONTINUES TO WARM WITH 850MB TEMPS CLIMBING TO
AROUND 18C THIS AFTERNOON. THIS SUPPORTS MAX TEMPS IN THE VALLEYS
IN THE MID TO UPPER 80S...OR ABOUT 10-12 DEGREES ABOVE NORMAL FOR
1ST OF SEPTEMBER. NORMAL HIGH AT BTV TODAY IS 76.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH THURSDAY/...
AS OF 356 AM EDT TUESDAY...HIGH PRESSURE REMAINS OVER THE REGION
TONIGHT. THIS WILL ALLOW FOR MAINLY CLEAR SKIES AND LIGHT

BETWEEN 06Z-12Z WEDNESDAY. MIN TEMPS RANGING FROM THE MID 50S IN
THE ADIRONDACKS AND NORTHEAST KINGDOM TO THE LOWER AND MID 60S IN
THE CHAMPLAIN AND ST LAWRENCE VALLEYS.

WEDNESDAY INTO THURSDAY AS A WEAK SHORTWAVE AND ASSOCIATED SURFACE
TROUGH MOVE SOUTHEASTWARD FROM ONTARIO AND SOUTHWEST QUEBEC. THIS
DISTURBANCE WILL DROP SOUTH ACROSS THE AREA WEDNESDAY NIGHT THROUGH
THURSDAY MORNING. WEDNESDAY WILL BE A VERY WARM DAY IN ADVANCE OF
THE WEAK FRONT. 850 MB TEMPS 18-20C...SO LOOK FOR MAX TEMPS IN
THE VALLEYS WELL INTO THE 80S TO AROUND 90 DEGREES. THESE TEMPS
COMBINED WITH DEWPOINTS IN THE MID 60S SUPPORT MUCAPE VALUES OF
AROUND 1500 J/KG AS FRONTAL FORCING AND SHORTWAVE TROUGH APPROACH
OUR INTERNATIONAL BORDER WEDNESDAY EVENING. HAVE CONTINUED WITH
20-30 POPS WITH MENTION OF POSSIBLE THUNDERSTORMS. ACTIVITY SHOULD
GENERALLY DIMINISH AS SHORTWAVE TROUGH PUSHES SOUTHEAST ACROSS OUR
REGION WEDNESDAY NIGHT THROUGH THURSDAY MORNING. MOSTLY CLOUDY
CONDITIONS SHOULD PRECLUDE FOG WEDNESDAY NIGHT. ALSO...CLOUDS
SHOULD KEEP MIN TEMPS IN THE LOWER TO MID 60S.

THERE WILL STILL BE A CHANCE FOR A FEW SHOWERS OR EVEN A
THUNDERSTORM DURING THURSDAY AS THE WEAK FRONT AND SHORTWAVE PUSH
SOUTH OF THE AREA. BEST CHANCE WILL BE ACROSS SOUTHERN PORTION OF
FORECAST AREA THROUGH 18Z. MORNING CLOUDS WILL GIVE TO INCREASING
SUNSHINE FROM NORTH TO SOUTH DURING THE AFTERNOON. 850MB TEMPS COOL
A BIT...TO AROUND 14C. EXPECT MAX TEMPS MAINLY IN THE LOWER TO MID
80S...WITH SOME UPPER 80S IN THE SOUTHERN VALLEYS.

.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...

RANGE REMAINS UNCHANGED AS THE NORTH COUNTRY WILL BE DOMINATED BY
A LARGE-SCALE UPPER RIDGE BUILDING OVER THE EASTERN CONUS. CLEAR
NIGHTS AND SUNNY DAYS ARE ON TAP THROUGH THE WEEKEND ALONG WITH
ABOVE NORMAL TEMPERATURES. NORMALS FOR EARLY SEPTEMBER ARE HIGHS
IN THE MID-70S, AND LOWS IN THE LOW/MID-50S BUT WITH PROGGED
850-925MB TEMPS OF +12-20C RESPECTIVELY WE`LL BE SEEING A RETURN

MID/UPPER 80S FOR MONDAY AND TUESDAY. LOWS WILL BE NEAR NORMAL FOR
THURSDAY NIGHT AN FRIDAY RANGING THROUGH THE 50S, BUT WARM INTO
