AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
150 PM EDT SAT APR 19 2014

.SYNOPSIS...
SURFACE HIGH PRESSURE WILL RIDGE OVER THE NORTH COUNTRY THIS
WEEKEND. TEMPERATURES WILL AVERAGE AROUND SEASONAL NORMALS...WITH
SUNDAY BEING THE WARMER OF THE TWO DAYS. NEXT CHANCE FOR
PRECIPITATION WILL BE TUESDAY WITH A SURFACE LOW CROSSING THE
AREA.

&&

.NEAR TERM /UNTIL 8 PM THIS EVENING/...
AS OF 1250 PM EDT SATURDAY...AFTER A RATHER RAW AND OVERCAST START
TO SATURDAY...STARTING TO FINALLY SEE SOME BREAKS IN THE OVERCAST
AS INCREASING DEEP-LAYER SUBSIDENCE BUILDS IN FROM THE NORTHWEST.
STILL EXPECT THE COOLEST TEMPS FOR THE REST OF TODAY TO BE ACROSS
THE NORTHEAST KINGDOM WITH CLOUDS BEING SLOWER TO LIFT THERE. ANY
LOWER ELEVATION RAIN/HIGHER ELEVATION SNOW SHOWERS WILL REMAIN
CONFINED TO THE NORTH-CENTRAL VERMONT/NORTHERN GREENS AREA AND
LIKELY NOT LAST MUCH LONGER THAN INTO THE MID- AFTERNOON. AS
CLOUDS BEGIN TO CLEAR OUT...LOOK FOR WINDS AND GUSTS TO INCREASE A
BIT UNDER BETTER MIXING. THOUGH CURRENT FORECAST GENERALLY ON
TRACK...GUIDANCE SEEMS TO BE TOO QUICK WITH DRYING THE LOW-LEVELS
OUT AND AS SUCH I'VE OPTED TO SLOW TIMING OF SHARPER FALLS IN SFC
DEWPOINTS WITH THIS UPDATE. HIGHS IN THE 40S/SPOT LOW 50S
(PRIMARILY SOUTHERN VERMONT) STILL LOOK ON TRACK.

&&

.SHORT TERM /8 PM THIS EVENING THROUGH MONDAY/...
AS OF 445 AM EDT SATURDAY...TONIGHT WILL BE CLEAR AND COLD WITH
WINDS DROPPING OFF AS SURFACE HIGH CRESTS OVER THE FORECAST AREA.
TEMPERATURES WILL BE BOTTOMING OUT IN THE TEENS AND TWENTIES...AN
IDEAL RADIATIONAL COOLING NIGHT. SURFACE HIGH WILL SHIFT EASTWARD
ON SUNDAY...WITH SOUTHERLY RETURN FLOW INCREASING TEMPERATURES
WILL BE AROUND NORMAL FOR THIS TIME OF YEAR...MAINLY UPPER 50S.
MOSTLY SUNNY SKIES ARE EXPECTED...A NICE DAY ON TAP. QUIET
WEATHER CONTINUES OVERNIGHT BUT WILL BE WARMER THAN TONIGHT. MIN
TEMPS WILL BE IN THE MID 30S TO LOWER 40S. MONDAY WILL BE ANOTHER
NICE DAY...WITH WARMING TREND CONTINUING AND MAX TEMPS IN THE
60S.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 350 AM EDT SATURDAY...THE TUESDAY-FRIDAY PERIOD OF NEXT
WEEK LOOKS TO START ON THE UNSETTLED SIDE...WITH CONDITIONS
IMPROVING AS THE WEEK PROGRESSES.

LOW PRESSURE WILL BE TRACKING THROUGH THE SAINT LAWRENCE VALLEY
TO START THE PERIOD MONDAY NIGHT. THIS WILL PLACE THE NORTH
COUNTRY IN THE WARM SECTOR AND UNDER SOUTHWEST FLOW...ALLOWING
FOR A RELATIVELY MILD NIGHT...WITH LOWS GENERALLY IN THE 40S.
SHOULDN'T BE MUCH IN THE WAY OF PRECIPITATION BUT CAN'T RULE OUT
A FEW SCATTERED RAIN SHOWERS.

A COLD FRONT WILL CROSS THE REGION TUESDAY/TUESDAY NIGHT WITH A
SECONDARY WAVE OF LOW PRESSURE DEVELOPING ALONG THE FRONT AS A
SHARPENING UPPER TROUGH APPROACHES. THE PLACEMENT OF THIS LOW
REMAINS TO BE SEEN...BUT A PERIOD OF RAIN AND SHOWERS IS LIKELY
FROM TUESDAY AND INTO TUESDAY NIGHT. EXACT PLACEMENT OF THE
SECONDARY LOW WILL DETERMINE LENGTH AND AMOUNT OF RAIN. AHEAD OF
THE FRONT...DESPITE THE CLOUDS AND RAIN...HIGHS SHOULD REACH INTO
THE 60S ON TUESDAY...WITH LOWS TUESDAY NIGHT POST-FRONT FALLING
BACK INTO THE 30S AND LOW 40S. SOME SNOWFLAKES ARE POSSIBLE ON
THE TAIL-END OF PRECIP IN THE HIGHER ELEVATIONS.

THE UPPER TROUGH WILL STILL BE OVERHEAD ON WEDNESDAY AND THIS
COMBINED WITH MOIST NORTHWEST FLOW WILL KEEP SOME CLOUDS AND
OROGRAPHIC RAIN AND MOUNTAIN SNOW SHOWERS AROUND. AS A RESULT
WE'LL ALSO BE LOOKING AT A BELOW NORMAL DAY IN TERMS OF
TEMPERATURES...45-55F FOR HIGHS. A RIDGE WILL BEGIN TO WORK INTO
THE REGION WEDNESDAY NIGHT AND BE IN FULL CONTROL BY THURSDAY AND
THURSDAY NIGHT...LEADING TO CLEARING SKIES AND A NICE DAY/COOL
NIGHTS. HIGHS NEAR NORMAL THURSDAY FROM 50-60F WITH LOWS FROM THE
UPPER 20S TO MID 30S BOTH NIGHTS. BY FRIDAY...SOUTHWEST FLOW WILL
BE INCREASING AHEAD OF THE NEXT SYSTEM SO WE'LL BE TRENDING ABOVE
NORMAL WITH HIGHS IN THE 60S.

&&

.AVIATION /18Z SATURDAY THROUGH THURSDAY/...
THROUGH 18Z SUNDAY...A RIDGE OF HIGH PRESSURE WILL BUILD SOUTHEAST FROM
CANADA AND WILL REMAIN OVER THE REGION THROUGH 18Z SUNDAY...WITH MAINLY
VFR CONDITIONS EXPECTED THROUGH THE PERIOD. VISIBLE SATELLITE LOOP
THROUGH 1730Z SATURDAY SHOWING LOW CLOUDS ACROSS THE REGION AT THIS
TIME. EXPECTING THESE CLOUDS TO DISSIPATE EARLY THIS EVENING DUE
TO THE LOSS OF DAYTIME SURFACE HEATING. EXPECTING SKIES TO BECOME CLEAR
THROUGHOUT THE REGION AFTER 00Z SUNDAY THROUGH 18Z SUNDAY.

OUTLOOK 18Z SUNDAY THROUGH THURSDAY...

18Z SUNDAY TO 12Z TUESDAY...VFR CONDITIONS EXPECTED AS A RIDGE OF
HIGH PRESSURE BUILDS INTO VERMONT AND NORTHERN NEW YORK.
