DISCUSSION
AS OF 231 PM EDT WEDNESDAY...
KEY MESSAGE 1: A STATIONARY FRONT DRAPED ACROSS THE FORECAST
AREA THIS AFTERNOON WILL PROVIDE THE FOCUS FOR A WINTRY MIX
TONIGHT AS IT LIFTS NORTH AS A WARM FRONT THROUGH THURSDAY. WEAK
SHORTWAVE ENERGY AND SURFACE LOW PRESSURE NORTH OF LAKE
SUPERIOR THIS AFTERNOON WILL TRACK WEST TO EAST ALONG THE FRONT
TONIGHT INTO THURSDAY MORNING WITH LOW/MID-LEVEL THERMAL
PROFILES GENERALLY SUPPORTING SCATTERED RAIN AND SNOW SHOWERS AS
SURFACE TEMPS RANGE THROUGH THE 30S. NORTHEASTERLY FLOW,
HOWEVER, WILL KEEP SURFACE TEMPERATURES BELOW FREEZING IN
NORTHERN ST. LAWRENCE VALLEY THROUGH AT LEAST THE FIRST HALF OF
THE NIGHT, AND WITH WARMING TEMPS ALOFT THIS WILL SUPPORT SOME
LIGHT FREEZING RAIN AND A FEW HUNDRETHS OF ICE ACCRETION THERE.
ELSEWHERE SNOW SHOWERS SHOULDN'T AMOUNT TO MUCH NEAR THE SURFACE
WITH WARM BOUNDARY LAYER TEMPS, BUT AND INCH OR TWO IS POSSIBLE
ACROSS THE HIGH PEAKS.
KEY MESSAGE 2: THE AFOREMENTIONED WARM FRONT CONTINUES TO MOVE
NORTH TO ABOUT THE INTERNATIONAL BORDER ON THURSDAY WITH GUSTY
SOUTHERLY WINDS PUSHING SURFACE TEMPS INTO THE UPPER 40S TO MID
50S ACROSS THE REGION. AFTER MORNING SHOWERS DISSIPATE, THE REST
OF THE DAYLIGHT HOURS SHOULD BE DRY BEFORE ADDITIONAL SHORTWAVE
ENERGY AND WEAK SURFACE LOW BRING ANOTHER ROUND OF
PRECIPITATION FOR THE EVENING AND OVERNIGHT HOURS. PRECIPITATION
WILL PREDOMINANTLY BE RAIN THROUGH MIDNIGHT BEFORE THE FRONT
BEGINS TO MOVE BACK SOUTH AS A COLD FRONT CHANGING RAIN TO SNOW
AT THE HIGHER ELEVATIONS FIRST, THEN BRIEFLY TO THE VALLEY FLOOR
DURING THE PRE-DAWN HOURS BEFORE ENDING BY THE MORNING COMMUTE.
MUCH LIKE THE PREVIOUS DAY, THE BULK OF SNOW ACCUMULATION WILL
BE ACROSS THE HIGHEST ELEVATIONS WITH SEVERAL INCHES POSSIBLE
ABOVE 2500 FEET, BUT BELOW THAT ONLY A DUSTING TO AN INCH IS
LIKELY. COLDER AND DRIER WEATHER FOLLOWS FOR FRIDAY THROUGH
SATURDAY WITH HIGHS IN THE MID-20S TO MID-30S AND LOWS FRIDAY
NIGHT COLD IN THE SINGLE DIGITS TO TEENS ABOVE ZERO.
KEY MESSAGE 3: AS HAS BEEN THE CASE RECENTLY, THE JET STREAM
REMAINS VERY FAST IN THE FORECAST. ENSEMBLES SUGGEST SPEEDS
ACROSS THE BELT OF WESTERLIES ACROSS CANADA WILL REMAIN NEAR TO
ABOVE THE 90TH PERCENTILE. SEVERAL EMBEDDED SYSTEMS WILL
CONTINUE TO ZIP ALONG THIS EXPRESS WITHOUT A REAL CONNECTION TO
DEEP, TROPICAL MOISTURE. IT DOES APPEAR TOWARDS THE BACK HALF OF
NEXT WEEK THAT THE PERSISTENTLY FAST FLOW WILL BREAK DOWN. SO A
PATTERN CHANGE IS POSSIBLE NEXT WEEKEND.
LOOKING AT SUNDAY, THE AXIS OF A 500MB TROUGH WILL SLIDE EAST
WITH A NEAR 1040MB HIGH SETTLING ACROSS THE MID-ATLANTIC.
WEATHER CONDITIONS WILL PROBABLY BE BEAUTIFUL WITH SUNSHINE AND
SEASONABLY COOL CONDITIONS IN THE MID 30S TO MID 40S. A SURFACE
LOW WITH MARGINAL MOISTURE WILL TRACK ACROSS QUEBEC PROVINCE ON
MONDAY AND DRAG A SURFACE TROUGH WITH SCATTERED SHOWERS THROUGH
THE AREA. TUESDAY APPEARS THE MOST LIKELY DRY DAY IN THIS
STRETCH BEFORE PRECIPITATION CHANCES RETURN. ANOTHER WARM FRONT
WILL TRACK ACROSS THE REGION WEDNESDAY. AS NOTED ABOVE, THE
BREAK DOWN OF CHANNELED FLOW WILL RESULT IN A MORE AMPLIFIED
WAVE PATTERN THAT WILL OPEN US UP TO MORE MOIST, SOUTHWESTERLY
FLOW FOR THE LATTER HALF OF NEXT WEEK. IT APPEARS SEVERAL
SHORTWAVES WILL EJECT NORTHEAST INTO THE NORTHEAST AHEAD OF THE
MAIN SYSTEM OF INTEREST TO TRACK INTO THE AREA TOWARDS NEXT
FRIDAY/SATURDAY.
AVIATION /06Z THURSDAY THROUGH MONDAY/
THROUGH 06Z FRIDAY...A STATIONARY BOUNDARY IS DRAPED FROM
ROUGHLY OGS TO BTV TO 1V4 THIS MORNING WITH POCKETS OF LIGHT
PRECIP LIFTING FROM SOUTHWEST TO NORTHEAST ACROSS OUR TAF SITES.
THIS PRECIP IS MAINLY FALLING AS VIRGA AS LOW LEVELS ARE DRY
WITH DEWPOINTS IN THE 20S, HOWEVER AS SATURATION CONTINUES
EXPECT SOME SCATTERED RAIN/SNOW SHOWERS WITH AREAS OF FREEZING
RAIN AT MSS. THE COMBINATION OF ADDITIONAL PRECIP AND LOW LEVEL
NORTHEAST FLOW, COULD PRODUCE A PERIOD OF IFR CIGS AT MSS
BETWEEN 06Z-08Z THIS MORNING. THE REST OF THE TAF SITES SHOULD
EXPERIENCE A MIX OF MVFR/VFR CIGS/VIS TRENDING TOWARD VFR AT ALL
SITES BY 12Z. AREAS OF LOW LEVEL WIND SHEAR AND TURBULENCE IS
LIKELY THROUGH THIS MORNING ASSOCIATED WITH 2000 TO 4000 FOOT
WINDS OF 35 TO 50 KNOTS. AS BETTER MIXING DEVELOPS SHEAR
DECREASES AND SURFACE WIND GUSTS INCREASE FROM THE
SOUTH/SOUTHWEST AT 10 TO 25 KNOTS. SURFACE LOW PRES AND
ASSOCIATED COLD FRONT DROP SOUTH THIS AFTERNOON/EVENING ACROSS
OUR TAF SITES WITH A PERIOD OF STEADY RAIN AND WINDS SHIFTING TO
THE NORTH. THIS WILL QUICKLY LOWER CIGS TOWARD IFR WITH RAIN
CHANGING TO SNOW BETWEEN 00Z-03Z BEFORE ENDING. A PERIOD OF IFR
CIGS ARE LIKELY AT MOST TAF SITES BETWEEN 22Z-04Z THIS EVENING.
OUTLOOK...
