AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
1004 AM EDT SAT APR 28 2012

.SYNOPSIS...
HIGH PRESSURE WILL BE BUILDING INTO THE NORTH COUNTRY TODAY...AND
WILL DOMINATE THE REGIONS WEATHER INTO EARLY NEXT WEEK. MORNING
CLOUDS WILL DISSIPATE BY MID-DAY...WITH CLEAR...DRY...AND
UNSEASONABLY COOL TEMPERATURES EXPECTED THROUGH THE WEEKEND.
SUNNY AND DRY CONDITIONS CONTINUE MONDAY...BEFORE WEAK LOW
PRESSURE MOVING INTO THE REGION BRINGS THE NEXT CHANCE FOR
PRECIPITATION MONDAY NIGHT AND TUESDAY.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
AS OF 958 AM EDT SATURDAY...TEMPERATURES HAVE CLIMBED ABOVE
FREEZING ACROSS THE CHAMPLAIN AND SAINT LAWRENCE VALLEYS...THUS
FREEZE WARNINGS CANCELLED A BIT EARLY. LOOKS LIKE MORE WARNINGS WILL
BE REQUIRED FOR TONIGHT HOWEVER. THREAT OF FLURRIES DIMINISHING AS
DRIER AIR BUILDS IN. HAVE REMOVED MENTION OF FLURRIES FOR MOST
VALLEY LOCATIONS. STILL COULD BE A FEW SNOW SHOWERS/FLURRIES OVER
THE MOUNTAINS...MAINLY OF NORTHERN VERMONT...THROUGH MIDDAY.
ADJUSTED HOURLY TEMPS/WINDS TO REFLECT LATEST CONDITIONS AND NEAR
TERM TRENDS. NO CHANGES MADE TO MAX TEMPS HOWEVER...WHICH LOOK TO
BE ON TARGET.

PREVIOUS DISCUSSION...
EXITING LOW PRESSURE CURRENTLY OVER THE GULF OF SAINT LAWRENCE
CONTINUES TO FEED THE NORTH COUNTRY WITH LOW LEVEL MOISTURE FROM
THE NORTHWEST...RESULTING IN MOSTLY CLOUDY SKIES AND SCATTERED
FLURRIES ACROSS THE REGION. HIGH PRESSURE OVER CENTRAL ONTARIO
WILL EVENTUALLY BUILD INTO THE FORECAST AREA BY LATER TODAY WHICH
WILL CLEAR OUT SKIES BY THIS AFTERNOON. ALREADY SEEING SOME AREAS
CLEARING OUT ACROSS FAR NORTHWESTERN NEW YORK...AND THE EXTREME
SOUTHERN CHAMPLAIN VALLEY. A MOSTLY SUNNY AND DRY AFTERNOON IS
EXPECTED AREA-WIDE...THOUGH TEMPS WILL BE ON THE COOL SIDE WITH
HIGHS ONLY IN THE 40S. WINDS WILL CONTINUE TO BE GUSTY AS WELL
TODAY...THOUGH NOT AS STRONG AS YESTERDAY WITH MEAN SPEEDS OF
10-15 MPH AND GUSTS AROUND 20 MPH. THIS WILL MAKE IT FEEL LIKE THE
TEMP IS IN THE UPPER 30S AND LOWER 40S SO BUNDLE UP OUT THERE.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH MONDAY/...
AS OF 415 AM EDT SATURDAY...HIGH PRESSURE WILL CONTINUE TO BE THE
DOMINATE WEATHER FEATURE ACROSS THE NORTH COUNTRY THROUGH MONDAY.
GENERALLY CLEAR SKIES ARE EXPECTED THROUGH THE PERIOD...WITH
BELOW NORMAL TEMPERATURES CONTINUING THROUGH SUNDAY NIGHT. WHILE
HIGH PRESSURE WILL BE MOVING IN AT THE SURFACE...AN UPPER TROUGH
REMAINS OVER THE REGION THROUGH SUNDAY...KEEPING WINDS A LITTLE
BRISK OUT OF THE NORTHWEST...AND TEMPS ON THE COOL SIDE.
INDEED...WE'RE LIKELY LOOKING AT 2 MORE NIGHTS OF LOW TEMPS
FALLING INTO THE TEENS AND 20S AREA-WIDE...WHICH WILL RESULT IN
MORE FREEZE WARNINGS FOR THE CHAMPLAIN AND SAINT LAWRENCE VALLEYS
WHERE THE GROWING SEASON HAS BEGUN. HIGH TEMPS SUNDAY WILL BE A
COUPLE DEGREES WARMER THAN TODAY WITH LITTLE OVERALL AIRMASS
CHANGE.

HIGH PRESSURE CRESTS OVER THE REGION BOTH AT THE SURFACE AND
ALOFT SUNDAY NIGHT AND BEGINS TO PUSH OFFSHORE ON MONDAY. THIS
WILL ALLOW FOR WARMER TEMPS TO RETURN THE AREA ON SOUTHERLY RETURN
FLOW. EXPECT HIGHS ON MONDAY TO BE MUCH WARMER THAN THE
WEEKEND...WITH VALLEYS PUSHING INTO THE UPPER 50S AND LOWER
60S...AND MID 50S ELSEWHERE.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
AS OF 425 AM EDT SATURDAY...HIGH PRESSURE OVER THE REGION MONDAY
SHIFTS EAST...FOLLOWED BY A SERIES OF FAST MOVING WEAK UPPER LEVEL
DISTURBANCES FOR PERIODIC CHANCES FOR RAIN FROM TUESDAY ONWARD. 00Z
GFS AND ECMWF FOLLOWED PREVIOUS 12Z RUNS IN BRINGING RAIN IN ON
TUESDAY. MODELS HAVE A HARD TIME RESOLVING TIMING AND PLACEMENT OF
SHORTWAVE TROUGHS IN THIS FAST ZONAL FLOW...AND THE TIME SHIFT WAS
NOT ENTIRELY OUT OF CHARACTER.

CHANCE POPS INCREASE WEST TO EAST ON TUESDAY IN WARM AIR ADVECTION
PATTERN IN ADVANCE OF APPROACHING 500MB SHORTWAVE TROUGH. ECMWF AND GFS
IN GENERAL AGREEMENT IN BREAK IN QPF FIELD UNDER SHORTWAVE RIDGING
ON WEDNESDAY...THEN MORE RAIN CHANCES WEDNESDAY NIGHT/THURSDAY
WITH THE NEXT TROUGH. PROBABLY FOLLY TO ATTEMPT TO GET TOO MUCH
TIMING DETAIL, BUT USED 6 HRLY MOS GUIDANCE FOR POP FIELDS IN
ORDER TO RESOLVE THE BREAK. 12 HRLY POPS WOULD HAVE HAD CHC POPS
CONTINUALLY FROM TUESDAY ONWARD AND I WANTED TO INDICATE A BREAK
IN THERE SOMEWHERE.

TEMPS...A WARMING TREND THROUGH THE EXTENDED PERIOD AS 1000-500MB
THICKNESS RISES...AND 850 MT TEMPS FORECAST TO RISE FROM NEAR
FREEZING MONDAY NIGHT TO LOW TEENS THROUGH MIDWEEK. MAX TEMPS IN
THE 70S ON THURSDAY ARE REALISTIC...BEFORE A COOL DOWN BEHIND A
WEAK COLD FRONT DROPS THEM BACK INTO THE 50S TO LOW 60S FOR
FRIDAY.

&&

.AVIATION /14Z SATURDAY THROUGH WEDNESDAY/...
THROUGH 12Z SUNDAY...MVFR TO VFR CIGS TO ERODE AWAY FROM NW
THROUGH 15Z. VIS SATELLITE SHOWING SMALL AREA CLOUDS OVER
KMSS..WITH SOLID OVC OVER REST OF THE TAF SITES. EXTRAPOLATION OF
CLEARING PUTS VFR NO CIG KSLK 13Z...15Z KPBG/KBTV...16Z
KMPV/KRUT. WSR-88D VAD WINDS INDICATE GUSTY WINDS RIGHT OFF THE
SURFACE...AND WITH SOME MIXING TODAY EXPECT RETURN OF SUSTAINED
10-15KT AND GUSTS TO 20-25 KT. AFTER CLEARING OCCURS WILL BE VFR
CLEAR FOR DURATION OF TAF PERIOD. CONSIDERED ADDING FOG FOR
KSLK/KMPV WITH CLEAR SKIES AND PROBABILITY OF ATMOSPHERE
DECOUPLING TOWARD MORNING...AND NEAR SURFACE MOISTURE DESPITE LOW
DEWPOINTS. HOWEVER FOR 20-24 HR OUT IN TAF PERIOD FELT PROBABILITY
FOR FOG TOO LOW AND LEFT OUT...BUT LATER SHIFTS MAY NEED TO RE-EVALUATE.
