Damage should begin over the next hour or 2 and steadily worsen thru the evening

THREAT THIS EVNG WITH A

NEAR-FRONTAL SQUALL LINE ALREADY BEGINNING TO TAKE SHAPE IN THE

VICINITY OF SYRACUSE NY. WILL NEED TO WATCH PRE-FRONTAL ENERGY

OVER ERN PA AND HOW IT EVOLVES AS THE SFC COLD FRNT BEGINS TO KICK

EWD. IT IS THE BELIEF THAT THE TONGUE OF HIGH-THETAE MOIST AIR

SURGING N ALONG THE WARM FRNT WILL ALSO USHER ELEVATED INSTABILITY

IN THE FORM OF LOW SHOWALTER INDICES AND LOW SFC LIFTED INDEXES

JUST BELOW THE CUSP OF SEVERE WX THRESHOLDS. WITH THE NEAR-FRONTAL

SQUALL LINE THERE IS THE BETTER CHC FOR HEAVY RAIN...DAMAGING

WINDS...AND PSBL ISOLATED TORNADOES WITHIN A VERY BRIEF PD OF TIME.

...WINDS...

WINDS HAVE BEGUN TO INCREASE ACROSS THE RGN WITH GUSTS AROUND 30

MPH ALONG THE SOUTH COAST OF NEW ENGLAND AND ACROSS HIGHER TERRAIN

/25 TO 30 MPH GUSTS ACROSS INTERIOR LOCALES/...BOTH AT THE SFC

AND WITHIN VERTICAL WIND PROFILER OBSERVATIONS. AN AVERAGE OF

40-45 KT WINDS /50-55 MPH/ IS PRESENTLY BEING OBSERVED AT H925

/2-3 KFT AGL/. THINKING REMAINS THE SAME...THE STRONGEST OF WINDS

HAVE BEGUN TO PUSH INTO NEW ENGLAND ALONG AND AHEAD OF THE COLD

FRNT AS SFC LOW PRES DEEPENS INTO THE ST LAWRENCE RVR VLY AGAINST

HIGHER PRES INTO THE ATLANTIC. WHILE SOME VERTICAL MIX- DOWN OF

FASTER MOMENTUM ALOFT IS EXPECTED THRU THE DAY /A CONDITIONALLY

UNSTABLE ENVIRONMENT/...THE GREATEST POTENTIAL OF STRONG TO

DAMAGING WINDS REACHING THE SFC WILL BE WITH RGNS OF HEAVY

RAINFALL...ESPECIALLY INTO THE EVNG PD WITH THE AFOREMENTIONED

NEAR-FRONTAL SQUALL LINE ANTICIPATED TO SWEEP THRU THE RGN AHEAD

OF THE SFC COLD FRNT.

THE WIND ADVISORY CONTINUES TO PREVAIL WITH THE EXPECTATION OF

STRONG TO DAMAGING GUSTY WINDS. IT IS POSSIBLE TO SEE HIGH WINDS

REACH THE SFC WITH GUSTS UP TO 60 MPH WITH THE FASTER JET EXPECTED

AHEAD OF THE FRONT PARENT WITH THE NEAR-FRONTAL SQUALL LINE

/PRECIPITATION DRAG OF FASTER MOMENTUM TO THE SFC/. HIGHER TERRAIN

LOCALES ABOVE 1 KFT WILL ALSO BE UNDER RISK FOR A GREATER

POSSIBILITY FOR HIGH WINDS AT OR ABOVE 60 MPH.

Max wind gusts in a lot of spots...esp central and east....could be between 8pm-2am tonight since that is when the peak of the LLJ comes through. For areas further SW like BDR, the peak will be later this afternoon into early evening.

Which is why areas farther east may struggle a bit I think

LOL..1-2 inches of upslope rain?

If you look at OKX radar...you can see the two different processes creating rain. One is probably from a combo of mid level processes...frontogenesis...s/w moving in etc. That is more from NW CT and into POU. The other is from the LLJ down near the CT coast. You can see how the showers blossom east a bit. Probably no coincidence with the LLJ moving east too.

Yeah there isn't going to be much instability to tap into.

The LLJ nearly reaches 70 knots over E MA, so if someone can get a heavier squall, won't be surprised to see some sfc gusts over 45 knots. But I'd be quite surprised if there was widespread gusts over those amounts.

Winds picking up a bit on Mt. Washington. Sitting at around 50 mph with a recent gust to 78. Nothing too extreme for up there yet.

We shut down the Gondola at Stowe early... had a big insurance company coming up for a group event this evening but they changed at the last minute and came up early this morning. Once they got off the top we shut it down.

I just got off the summit on the 4-wheeler and wow are the gusts ripping up there. Surprisingly it'll go almost dead calm for a minute or so and then you can hear the gust coming and it moves through like a freight train at 50-60mph for a minute before dying off again. Very interesting but man some of those gusts were impressive...flags are straight out.

Highest so far at the weather station on Mansfield is 65mph.

shows you what a joke the work that has been done since the 2 storms...a few 30-35 mph gusts and 2000 people are out...we're no better off than we were before Irene and the Oct blizzard.

Don't disagree...but I kind of wonder if there's a lasting impact from those two storms at play here. Could weakened limbs that didn't come down last year be a threat? I only wonder because I've notice since I've been back in time just after one or two rain storms a few limbs down around town. Wasn't much wind to bring them down, so just makes me wonder if they were weakened last year and ready to come down the first times someone sneezes. Some fodder for the damage weenies anyway.
