OVRNGHT FROM SE...SO MAIN THREAT WL BE ALG WRN SLOPES OF GREEN MTNS
WHERE HIGH WIND WARNING IN EFFECT. PRESENCE OF INVERSION EXPECTED TO
LIMIT HIGH WIND THREAT ACRS REST OF FA. EVERYTHING WELL COVERED IN
GOING FCST. NO UPDATE NEEDED ATTM.
...PREVIOUS DISCUSION BELOW.....
...ICE AND WIND...
APOLOGIES FOR LATENESS...A LONG MRNG UPDATE TO SIGNAL EVENTUAL AFTN
PKG HEADLINES PUT ME BEHIND AND HAVE BEEN CATCHING UP EVER SINCE BUT
ALL PUBLIC PRODUCTS HAVE BEEN ISSUED.
..SHORT TERM DISCUSSION (TNGT THRU SAT)...
HIGH WINDS - STG LLVL JET >70KTS BUT INVERSION IN PLACE (HOW
STRONG?) BUT SE COMPONENT IN CLIMO FVRD WRN SLOPES OF GRN MTNS
BRGS THREAT TO AREA. KRUT HAS BEEN 15G25MPH WITH LTL GRADIENT
AND ALRDY SEEING ANTHR SE COMPONENT AREA (BLACK RVR VLY NY)
WITNESSING STG WNDS - KGTB 15025G35KT (GOOD INDICATOR FOR OUR FA).
FRZG RAIN - THE ABV INVERSION AND LACK OF MIXING E OF SPINE OF
NRN GRN MTNS AND TIMING OF PCPN KEY IN ANY PSBL FZRA AT ONSET.
CRNT TMPS IN L-M20S IN CT RVR VLY AND INVERSION PREVENTING MIXING
WL KEEP TMPS BLO FRZG THRU DAYBRK IN VLYS AND EVENTUAL WRMG ABV
FRZG BY MIDDAY. QPF DOESNT ARRIVE TIL 08/09Z BUT TMPS BLO FRZG
WL ALLOW FOR MINOR ICE BUILD-UP.
IN NRN ST LWRNC VLY...KMSS RPTG E WND ARD 10 MPH WITH TMPS IN L-M20S
AND SE GRADIENT HOLDS E WND THERE FOR AWHILE. QPF ARRIVES BY MIDNGT
AND ACCUM LKLY BFR GRADUAL WARMUP THU MRNG.
THEREFORE...WNTR WX ADV FOR THOSE LOCALES.
FLOODING - SNOWMELT WL OCCUR BUT NOT DRASTIC AS ABV FRZG TMPS ARE
SHORT-LIVED. QPF AMTS GENERALLY LESS THAN AN INCH AND FALLING INTO
SNOWPACK THAT IS CRNTLY AOB 10 PCT RIPE. LOCAL DRAINAGE...ACTUALLY
SNOW/ICE COVERED DRAINS MAY SEE SOME PONDING OF WATER BUT WE SHLD
BE OK.
THE XCPTN TO THIS RULE WL BE THE HIGHEST ELEV OF GRN MTNS WHERE STG
S/SE WNDS OF >50 KTS COMBINED WITH T/TD IN 40S SHLD ACCELERATE SOME
OF THE SNOWMELT THAT HAS BEEN OCCURRING THERE TDY WITH TMPS IN 40S
TDY.
COORD WITH NERFC ERLR...BELIEVE SNOWPACK IN HIGHEST ELEVATIONS WL
RIPEN WITH SOME RELEASE AS RUN-OFF INTO STREAMS AND LWR ELEVATIONS.
MEANWHILE...LWR ELEVATIONS HAVE AN EQUALLY SUBSTANTIAL SNOWPACK AND
WL NOT EXPERIENCE AS MUCH AS A SNOWMELT. THEREFORE...RUNOFF FM
HIGHER ELEVATIONS WL LKLY RUN INTO LWR ELEVATION SNOWPACK AND
INCREASE RIPENESS BUT PREVENT FM A MASSIVE RUNOFF AND FLOODING
PRBLMS.

.LONGER TERM DISCUSSION...
LOW FINALLY EXITS INTO THE CANADIAN MARITIMES LATE FRI INTO SAT...AS
RIDGE OF HIGH PRESSURE WORKS EAST ACROSS THE MIDWEST/GREAT LAKES
REGION INTO THE NORTHEAST. ETA AND AVN/GFS MDLS SHOWS THE
POSSIBILITY OF SOME LIGHT LK EFFECT OFF LAKE ONTARIO AS HIGH MAKES
ITS WAY EAST OVER OUR AREA. 500MB HGTS ON ETA MDL HAVE WESTERLY FLOW
OVER LAKE. SFC WND FLOW WILL BE LIGHT AS HIGH MVS EAST. WILL
CONSIDER A CHANCE FOR SOME...BUT ONLY IN THE SOUTHERN PORTIONS OF
THE DACKS. OTHERWISE LOOKING FOR MSUNNY SKIES OVER AREA FOR THE DAY
SAT.
SUNDAY INTO MONDAY LOOKS AGAIN TO BE CHANGING FROM RUN TO RUN.
LATEST 12Z AVN/GFS RUN NOW HAS LOW MOVING CLOSER TO SOUTHERN NEW
ENGLAND(SOUTH OF CAPE COD) THAN THE PREVIOUS RUN(WHICH WAS BEING
PUSHED EAST OFF COAST NEAR VA/NC AREA. IF THIS RUN HOLDS...THE
SOUTHERN HALF OF CWA SEE MORE SN AND WILL CONSIDER BUMPING UP POPS
IN THAT AREA NOW NEWLY AFFECTED. LOW THEN MVS FAR ENOUGH DURING DAY
MONDAY. SOME LINGER SN FOR EASTERN HALF VT POSSIBLE UNTIL LOW PULLS
AWAY FROM REGION.
RIDGE OF HIGH PRESSURE BUILDS INTO REGION DURING DAY MONDAY INTO
TUESDAY...BEFORE ANOTHER LOW HEADS TOWARDS REGION FROM THE SE ON
WEDNESDAY. WITH MDL GUIDANCE STILL INDECISIVE ON STORM TRACK FOR
SUN/MON...WILL JUST GO WITH CHANCE OF SN FOR NOW AND WAIT FOR
FURTHER RUNS TO SEE WHERE LOW WILL TRACKS.
