1. MUCH COLDER AND MAINLY DRY CONDITIONS EXPECTED TODAY INTO

DISCUSSION
AS OF 259 AM EDT FRIDAY...
KEY MESSAGE 1: A COLD FRONT WILL CONTINUE TO SLIDE THROUGH THE REGION
THIS MORNING LEADING TO A TAPERING OFF OF ANY LINGERING RAIN OR SNOW
SHOWERS ACROSS THE REGION. BEHIND THE FRONT FOR THE REST OF TODAY,
HIGH TEMPERATURES WILL STRUGGLE TO REACH THE FREEZING MARK WITH
VALUES IN THE UPPER 20S TO LOW 30S UNDER STRONG NORTHWESTERLY CAA.
SOUTHERN WINDSOR AND RUTLAND COUNTIES MAY BE ABLE TO BREAK INTO THE
MID 30S WITH SOME ADDITIONAL CLEARING SKIES AND BETTER DIURNAL
HEATING PROFILES. BREEZY CONDITIONS THIS MORNING WITH GUSTS BETWEEN
20-25 MPH, WILL SUBSIDE BY THIS AFTERNOON AS WE TREND TOWARDS
LIGHTER NORTHERLY WINDS 10-15 MPH. WITH THE BREEZES, FEELS LIKE
TEMPERATURES THIS MORNING INTO THE EARLY AFTERNOON WILL BE IN THE
SINGLE DIGITS TO TEENS. REGARDLESS, WIDESPREAD CLEARING SKIES FROM
MID TO UPPER LEVEL DRYING TODAY, WITH A MARCH SUN ANGLE, SHOULD MAKE
IT FEEL SLIGHTLY WARMER THAN THE HIGH TEMPERATURES WOULD SUGGEST.
FRIDAY NIGHT WILL, IN ALL LIKELIHOOD, BE THE LAST TRUE COLD NIGHT OF
THE SEASON AS LOWS DIP TO THE SINGLE DIGITS FOR MOST LOCATIONS
OUTSIDE OF SOUTHERN VERMONT AND THE CHAMPLAIN VALLEY WHERE LOWS WILL
FALL TO THE LOW TO MID TEENS. A FEW SHELTERED LOCATIONS IN THE
ADIRONDACKS AND FAR NORTHERN NORTHEAST KINGDOM COULD POTENTIALLY
NEAR 0 DEGREES. LOWS IN GENERAL WILL NOT BE RECORD BREAKING BY ANY
MEANS, BUT RATHER 10 DEGREES BELOW AVERAGE. THIS UNSEASONABLE COLD
AIR IS SUPPORTED BY -15C TO -19C 925 AND 850MB TEMPERATURES. WITH
HIGH PRESSURE WILL BUILD IN FOR SATURDAY KEEPING THE REGION UNDER
UNSEASONABLY COOL CONDITIONS WITH HIGHS AROUND 10-15 DEGREES BELOW
NORMAL. HIGHS WILL ONCE AGAIN STRUGGLE TO REACH THE FREEZING MARK
AREAWIDE WITH HIGHS IN THE MID 20S TO LOW 30S, AS NORTHWEST FLOW
CONTINUES TO KEEP COOL CANADIAN AIR FUNNELED INTO THE AREA.
NORTHWEST FLOW WILL BECOME BREEZY ON SATURDAY WHICH WILL HELP FEELS
LIKE TEMPERATURES NOTABLY, WHILE THERE IS MODERATE CONFIDENCE IN
CALM WEATHER ON SATURDAY FOR MOST LOCATIONS, LAPSE RATES WILL BE
RELATIVELY STEEP WITH SOME ENERGY RIDING ALONG THE NORTHERN
PERIPHERY OF THE HIGH PRESSURE, WHICH COULD LEAD TO SOME ISOLATED
CONVECTIVE LIGHT SNOW SHOWERS. CONFIDENCE IS LOW IN SHOWER ACTIVITY
GIVEN THE HIGH AND DRY AIR ACROSS THE AREA, AND ANY SHOWERS WOULD
NOT CAUSE ANY IMPACTS AS ACCUMULATIONS WOULD BE MINIMAL WITH LIMITED
MOISTURE, BIT SOME ISOLATED CHANCES (25-35% CHANCE), MAINLY IN THE
HIGHER TERRAIN OF THE ADIRONDACKS ARE POSSIBLE. LIGHT SNOW SHOWERS
(15-25% CHANCE) WILL CONTINUE INTO SUNDAY AS A WARM FRONT PASS
THROUGH NORTH OF THE REGION, BUT MOISTURE WILL REMAIN LIMITED.
TEMPERATURES SUNDAY WITH THE WARM FRONT WILL REBOUND FROM SATURDAY
WITH HIGHS INTO THE 40S.
KEY MESSAGE 2: THE LATEST FORECAST FROM WPC SHOWS THE HIGHEST
PROBABILITY OF PRECIP LATE TUES THROUGH WEDS WITH POPS IN THE
55% TO 70% RANGE. THE FIRST ROUND OF PRECIP IS ASSOCIATED WITH
SHARP WARM FRONT LIFTING SOUTHWEST TO NORTHEAST ACRS OUR CWA,
ALONG WITH A STRENGTHENING 850MB JET OF 50 TO 70 KNOTS. THIS WL
RESULT IN GUSTY RIDGETOP WINDS OF 45 TO 55 KNOTS ON TUES INTO
WEDS, WITH SOME DOWNSLOPE SHADOWING IN THE QPF FIELDS LIKELY
ACRS THE CPV AND LOWER CT RIVER VALLEY. LATEST 00Z GFS IS VERY
WARM FOR LATE TUES INTO WEDS, WITH A NON-DIRUNAL TEMP TREND
LIKELY, ESPECIALLY GIVEN WINDS AND CLOUDS/PRECIP. PROGGED 925MB
TEMPS ARE IN THE 12-15C RANGE ON THE GFS, BUT COOLER ON THE
ECMWF AS BOUNDARY REMAINS DRAPED ACRS OUR REGION WITH LIMITED
SUCCESS BREAKING OUT INTO THE WARM SECTOR. CURRENT TEMPS BY WPC
FOR OUR AREA SHOW HIGHS MID 40S TO NEAR 50F FOR TUES AND WELL
INTO THE 50S FOR WEDS. IF THE GFS WAS TO VERIFY HIGHS WEDS COULD
BE WELL INTO THE 60S WITH SOME LOWER 70S POSSIBLE, SOMETHING TO
WATCH. MUCH COOLER AIR FILTERS INTO THE REGION ON THURS INTO
FRIDAY WITH ANOTHER SYSTEM APPROACHING THE AREA BY FRIDAY. HIGHS
GENERALLY COOL BACK TO NORMAL ON THURS AND FRIDAY WITH VALUES IN
THE UPPER 30S TO NEAR 50F, DEPENDING UPON YOUR LOCATION. OVERALL
THE PROBABILITY OF SIGNIFICANT OR HIGHLY IMPACTFUL WX DURING THE
DAYS 4 THRU 7 FORECAST PERIOD IS LOW ATTM.
AVIATION /06Z FRIDAY THROUGH TUESDAY/
THROUGH 06Z SATURDAY...AVIATION CHALLENGE IS TIMING THE
IMPROVING CONDITIONS FROM IFR/LIFR TO MVFR/VFR ACROSS OUR TAF
STIES THIS MORNING. CURRENTLY A WIDE RANGE OF FLIGHT CATEGORIES
FROM LIFR AT MPV TO IFR AT BTV/RUT/SLK/EFK AND MVFR AT MSS AND
VFR AT PBG. BRISK NORTH TO NORTHWEST WINDS WILL CONTINUE TO
SLOWLY ADVECT DRIER AIR WITH IMPROVING CIGS/VIS FROM NORTH TO
SOUTH ACROSS OUR TAF SITES THIS MORNING. THE COMBINATION OF LOW
LEVEL CONVERGENCE AND BLOCKED FLOW, FEEL IFR CIGS LINGER THE
LONGEST AT RUT, WHILE EFK SHOULD SEE IMPROVEMENT IN THE NEXT 1
TO 2 HOURS. ALSO, FEEL DEVELOPING SUBSIDENCE INVERSION WILL HELP
TO PUSH SHALLOW MOISTURE TOWARD THE SURFACE AT SLK, RESULTING
IN ADDITIONAL IFR CIGS THRU 10/11Z. ELSEWHERE, CONDITIONS SHOULD
IMPROVE TO MVFR/VFR OVER THE NEXT 2 TO 3 HOURS AS LOCALIZED
WINDS GUST IN THE 15 TO 25 KNOT RANGE. CONDITIONS CONTINUE TO
IMPROVE TO VFR AS SURFACE HIGH PRES DEVELOPS ON FRIDAY WITH
LIGHTER WINDS BY MID AFTERNOON AND MOSTLY SUNNY SKIES.
