AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BURLINGTON VT
343 PM EDT WED SEP 9 2015
.SYNOPSIS...
COLD FRONT PUSHES EAST ACROSS OUR FORECAST AREA THIS EVENING THEN
STALLS OUT OVER SOUTHERN NEW ENGLAND THROUGH FRIDAY. WEATHER
BECOMES MORE ACTIVE FROM SATURDAY ONWARD WITH SEVERAL CHANCES FOR
SHOWERS AND MORE SEASONABLE TEMPERATURES.
&&
.NEAR TERM /UNTIL 8 AM THURSDAY MORNING/...
AS OF 335 PM EDT WEDNESDAY...SHOWERS AND THUNDERSTORMS WILL
CONTINUE TO PUSH EASTWARD ACROSS OUR FORECAST AREA THIS EVENING AS
COLD FRONT PROGRESSES EASTWARD. SHOWERS WILL END FOLLOWING FRONTAL
PASSAGE AND ALSO WITH LOSS OF DAYTIME HEATING...SHOULD BE CLEARING
EAST OF VERMONT BY ABOUT 03Z. SKIES REMAIN MOSTLY CLOUDY OVERNIGHT
AND SOME PATCHY FOG MAY DEVELOP IN AREAS WHICH HAD HEAVY RAIN
TODAY. MINIMUM TEMPERATURES WILL BE IN THE MID 50S TO LOWER 60S
WITH THE COOLEST TEMPS ACROSS NORTHERN NEW YORK WHERE COLD AIR
ADVECTION PICKS UP OVERNIGHT AND A WEAK SURFACE RIDGE BUILDS INTO
THE AREA.
&&
.SHORT TERM /8 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/...
AS OF 345 PM EDT WEDNESDAY...COLD FRONT WHICH CROSSED THE AREA
OVERNIGHT WILL STALL OVER SOUTHEASTERN NEW ENGLAND ON THURSDAY AND
REMAIN THROUGH FRIDAY. A SURFACE LOW DEVELOPS AND RIDES ALONG THE
FRONT KEEPING CHANCE FOR SHOWERS OVER OUR SOUTHEASTERN ZONES
THROUGH MOST OF THE PERIOD. OTHERWISE WEAK RIDGE OF HIGH PRESSURE
WILL BUILD OVER MOST OF OUR FORECAST AREA AND DRIER WEATHER
RETURNS WITH MORE SEASONABLE...BUT STILL SLIGHTLY ABOVE
NORMAL...TEMPERATURES. LOW WILL PASS FROM NEAR THE DELMARVA AREA
AT 00Z FRIDAY...SLOWLY NORTHEASTWARD TO NEAR NOVA SCOTIA BY 12Z
SATURDAY. SKIES WILL REMAIN FAIRLY CLOUDY ACROSS OUR AREA THROUGH
THE PERIOD.
&&
.LONG TERM /SATURDAY THROUGH WEDNESDAY/...
AS OF 335 PM EDT WEDNESDAY...THE WEEKEND BEGINS WITH A MODERATELY
STRONG UPPER LEVEL TROUGH OVER THE OHIO VALLEY AND THERE HAS BEEN
DECENT RUN TO RUN CONTINUITY WITH THE OVERALL IDEA OF A UPPER
MIDWEST TROUGH OVER THE WEEKEND BETWEEN MODELS. AS THE TROUGH DIGS
IN EASTWARD THERE IS A BIT OF DIVERGENCE IN THE TIMING OF THE
MODELS SO I HEDGED A BIT TOWARDS THE SLOWER ECMWF AND A
COMBINATION OF THE PREVIOUS FORECAST. EITHER WAY THE WEEKEND AND
INTO EARLY NEXT LOOKS LIKE A TEMPORARY BREAK FROM THE PATTERN OF A
BROAD SEMI PERMANENT UPPER LEVEL RIDGE WITH RAIN SHOWERS LIKELY.
THAT SHOULD HELP TO BRING SOME MUCH NEED RAIN TO THE AREA WITH
UPWARDS OF 1/2"-1" INCHES ACROSS THE FORECAST AREA THROUGH THE
WEEKEND. UNFORTUNATELY THE BREAK IN THE PATTERN WONT LAST AND THE
BEGINNING OF THE WEEK WILL SEE RISING HEIGHTS AND INCREASING
THICKNESS ON LATE MONDAY INTO TUESDAY AND A RETURN OF SLIGHTLY
ABOVE AVERAGE TEMPERATURES INTO THE MID WEEK WITH MAX TEMPS IN THE
UPPER 70S AND LOWS IN THE MID TO UPPER 50S.
&&
.AVIATION /20Z WEDNESDAY THROUGH MONDAY/...
THROUGH 18Z THURSDAY...AN ADVANCING COLD FRONT WILL PRODUCE
SHOWERS ACROSS THE FORECAST AREA AND IMPACT ALL TAF SITES. EXPECT
THE SOUTH TO SOUTHWESTERLY GRADIENT WINDS TO CONTINUE THROUGH THE
AFTERNOON BEFORE GOING CALM OVERNIGHT BEHIND THE FRONT. I
CONTINUED THE APPROACH OF PREVAILING VCSH FOR THE FORECAST AREA
AND TEMPO'D IN MVFR CONDITIONS FOR THE SHOWERS MOVING THROUGH.
THUNDER WILL BECOME MORE PREVALENT HOWEVER DUE TO INDIVIDUAL
TIMING CONCERNS I WILL NOWCAST THUNDER THROUGH AMENDMENTS. SOME OF
THE SHOWERS WILL BE ON THE STRONG SIDE WHICH COULD PRODUCE
TURBULENCE AND LOCALIZED WIND SHEAR. TIMING WILL BRING THE SHOWERS
THROUGH THE CHAMPLAIN VALLEY BEGINNING AT 20-21Z AND CLEARING BY
02-03Z. WITH EXPECTED CLEARING SKIES AND DECREASING WINDS I
ANTICIPATE THERE WILL BE SOME AREAS OF IFR AND POSSIBLY LIFR
FOG/BR WITH THE MOST LIKELY SPOTS BEING AT SLK/MPV.
18Z THURSDAY THROUGH MONDAY... 18Z THU - 00Z FRI: VFR EXPECTED
UNDER WEAK HIGH PRESSURE
00Z FRI - 00Z SAT: VFR EXPECTED WITH BRIEF PERIODS OF MVFR
SHOWERS ACROSS SOUTHERN VT. POSSIBLE MVFR/IFR FOG/BR OVERNIGHT.
00Z SAT - 00Z SUN: VFR EXPECTED WITH BRIEF PERIODS OF MVFR
SHOWERS ACROSS THE FORECAST AREA.
00Z SUN ONWARD: VFR CONDITIONS PREVAILING WITH POSSIBLE GUSTY
DOWNSLOPE WINDS AT RUT ON SUNDAY AFTERNOON.
