NATIONAL WEATHER SERVICE BURLINGTON VT
253 AM EDT SAT OCT 29 2011
.SYNOPSIS...
HIGH PRESSURE WILL REMAIN OVER THE NORTH COUNTRY INTO EARLY
SATURDAY. A LOW PRESSURE SYSTEM STRENGTHENING AS IT MOVES UP THE
EAST COAST WILL BRING PRECIPITATION TO THE AREA LATE SATURDAY
INTO SUNDAY...WITH THE GREATEST POTENTIAL BEING OVER SOUTHERN
AREAS OF VERMONT WHERE SIGNIFICANT AMOUNTS OF SNOW ARE POSSIBLE.
HIGH PRESSURE RETURNS LATE SUNDAY INTO WEDNESDAY. ANOTHER LOW
AFFECTS THE REGION LATER NEXT WEEK.

TEMPS DOWN BASED ON LATEST AREA OBS. REST OF FORECAST IN GD SHAPE
FOR THE OVERNGT PERIOD.
PREVIOUS FORECAST...ONLY MINOR CHANGES WERE MADE TO BETTER
REFLECT THE HIGH CLOUDS STREAMING INTO THE REGION THIS EVENING AND
TO TAKE THE LOW TEMPERATURES DOWN A FEW DEGREES...MAINLY ACROSS
NEW YORK WHERE CLEAR SKIES HAVE LED TO RAPID RADIATIONAL COOLING.
VERY DRY CONDITIONS IN THE LOW LEVELS ALSO LED TO RAPID COOLING
ACROSS VERMONT SO CONTINUED THE QUICK DOWNWARD TREND THIS EVENING
BEFORE LEVELING OFF OVERNIGHT AS HIGH CLOUDS CONTINUE TO INCREASE.
LOW TEMPERATURES GENERALLY MID TO UPPER 20S IN THE CHAMPLAIN
VALLEY...LOW TO MID 20S ACROSS THE SAINT LAWRENCE VALLEY AND MUCH
OF VERMONT...AND UPPER TEENS IN THE ADIRONDACKS AND COLDEST
LOCATIONS OF THE NORTHEAST KINGDOM.
&&
.SHORT TERM /6 AM THIS MORNING THROUGH SUNDAY NIGHT/...
AS OF 343 PM EDT FRIDAY...HIGH PRESSURE OVER THE AREA EARLY SATURDAY
WILL ALLOW FOR SUNSHINE TO START THE DAY. THE HIGH RETREATS INTO
SOUTHEASTERN CANADA BY AFTERNOON. MEANWHILE...STRONG SHORTWAVE MOVING
EAST FROM LOWER OHIO VALLEY WILL REACH THE EAST COAST BY SATURDAY
EVENING. WEAK LOW PRESSURE NEAR CAPE HATTERAS SATURDAY MORNING WILL
UNDERGO SIGNIFICANT DEEPENING IN RESPONSE TO THIS ENERGY AS THE LOW
TRACKS NORTHEASTWARD. EXPECT THE LOW CENTER TO BE LOCATED SOUTH OF
LONG ISLAND SATURDAY EVENING...NEAR CAPE COD AROUND MIDNIGHT
SATURDAY NIGHT...AND SOUTH OF NOVA SCOTIA BY SUNDAY AFTERNOON.
MODELS HAVE TRENDED FURTHER NORTH AND WEST OVER PAST 24 HOURS WITH
TRACK OF THE LOW AND THE ASSOCIATED PRECIPITATION SHIELD. WHILE BEST
FRONTOGENESIS AND ISENTROPIC LIFT WILL BE SOUTH OF BTV CWA...ENOUGH
DYNAMICS/LIFT AND EXPECTED QPF TO WARRANT CONTINUANCE OF WINTER
STORM WATCH FOR RUTLAND/WINDSOR/ORANGE COUNTIES IN VERMONT. HPC QPF
IS LESS THAN VARIOUS MODELS SUCH AS GFS/NAM/SREF...SO HAVE BLENDED
HPC WITH AVERAGE OF OTHER MODELS. THIS RESULTS IN .50 TO .75 INCHES
IN WATCH AREA...WHERE 4 TO 8 INCHES OF WET SNOW EXPECTED. WITH
LEAVES STILL ON SOME TREES...THERE IS POTENTIAL FOR DOWNING OF
SOME TREE LIMBS AND POWER LINES. PCPN AND SNOW AMOUNTS TAPER
FURTHER NORTH AND WEST OF THE WATCH AREA...BUT MAY NEED TO
CONSIDER ADVISORIES FOR ZONES ADJACENT TO THE WATCH AREA WHERE 2
TO 5 INCHES POSSIBLE. AMOUNTS DECREASE FURTHER FROM CHAMPLAIN
VALLEY WEST...WITH MAINLY DRY CONDITIONS EXPECTED IN ST LWR VLY.
TEMPS ON SATURDAY WILL TOP OFF IN THE LOWER 40S...BUT WILL COOL
QUICKLY WITH START OF PRECIPITATION DUE EVAPORATIONAL COOLING. SO

.LONG TERM /MONDAY THROUGH FRIDAY/...
AS OF 343 PM EDT FRIDAY...DRY AND NEAR SEASONABLE MID-AUTUMN WEATHER
WILL HIGHLIGHT MUCH OF THE EXTENDED PORTIONS OF THE FORECAST
DURING THE EARLY TO MIDDLE PORTIONS OF NEXT WEEK. PERUSAL OF
MEDIUM RANGE OPERATIONAL AND SUPPORTING ENSEMBLE MEAN SOLUTIONS
PAINTS A CONSISTENT IDEA THAT DEEP LAYER HIGH PRESSURE WILL BE THE
DOMINANT WEATHER MAKER ACROSS THE NORTHEAST MONDAY INTO WEDNESDAY.
THERE COULD BE A FEW CLOUDS FROM TIME TO TIME...ESPECIALLY ON
MONDAY AS A WEAKENING UPPER SHORTWAVE DAMPENS MOVING EAST INTO THE
RIDGE AXIS...BUT OVERALL NOT A BAD STRETCH OF WEATHER. BASED OFF
LOW LEVEL THERMAL PROFILES... WILL LEAN CLOSE TO...BUT OFFER
SLIGHTLY WIDER-THAN-NORMAL DIURNAL RANGES THAN AVBL MOS
GUIDANCE...ESP GIVEN POSSIBILITY OF SOME SNOW COVER ACROSS OUR
SOUTHERN COUNTIES.
THEREAFTER...AS CUSTOMARY...MODELS BEGIN TO DIVERGE ON HOW TO HANDLE
ADDITIONAL FRONTAL ENERGY PUSHING EAST FROM THE OHIO VALLEY/GREAT
LAKES BY THURSDAY/FRIDAY...WITH TIMING DIFFERENCES QUIET NOTABLE
EVEN AMONG THIS MORNING'S GFS OP RUN AND ITS SUPPORTING ENSEMBLE
MEAN. THEREFORE...WILL LEAN MORE CONSERVATIVELY HERE PAINTING ONLY
BROAD 30/40% POPS UNTIL BETTER CONSENSUS IS REACHED. WITH MILDER
SOUTHERLY FLOW AHEAD OF APPROACHING SYSTEM...FEEL PTYPE WILL LEAN
MORE HEAVILY TOWARD THE LIQUID FORM UNTIL COLDER AIR PUSHES BACK
