They were plowing the half inch we got I thought it was kind of funny lol wish we had more moisture to work with today

I figured this is at least as interesting as yesterday's 0.1" dusting that got people excited.

Radar has squalls punching through NY state and maybe some near Pittsfield

Winds here in N ORH county are picking up after being calm.

Clouds increasing. Looking to see if I can hit -10F

10 AM UPDATE...

MONITORING THE SNOW-BAND S OF THE S NEW ENGLAND COASTLINE. WIND

TRAJECTORIES INITIALLY W ALLOWING FOR A DECENT OCEAN-EFFECT BAND

OUT OF LONG-ISLAND SOUND. WITH WINDS A BIT MORE NW...THE BAND

SEEMINGLY IS REMAINING S OF MVY / ACK. REPORTS ON ACK OF SNOW AND

REDUCED VISIBILITIES...BUT EXPECT HEAVIEST OF SNOW TO REMAIN S OF

THE ISLAND.

OTHERWISE...NEAR-TERM MESOSCALE GUIDANCE WOULD LEAD YOU TO

BELIEVE THAT THE CHANCE OF SNOW-SQUALLS DOES EXIST PARENT WITH THE

ANTICIPATED ARCTIC FRONT WHICH WILL SWEEP THE REGION AROUND THE 1

PM TO 4 PM TIMEFRAME. GOOD LAPSE RATES...STRONG NW-WINDS...ENOUGH

LOW-LEVEL MOISTURE...YET LIMITED MAKING FOR AN ISOLATED-SCATTERED

SNOW-SQUALL EVENT. HIGHEST CONFIDENCE IS ALONG THE W-SLOPES OF

HIGHER TERRAIN WITH OROGRAPHIC TENDENCIES. NEVERTHELESS...HAVE

FOLLOWED WITH CHANCE POPS ACCORDINGLY AND THE EXPECTATION OF

MEASURABLE SNOW ACCUMULATIONS LESS THAN AN INCH. WITH ANY SNOW-

SQUALL ACTIVITY...VISIBILITIES WILL DROP RESULTING IN ADVERSE /

HAZARDOUS TRAVEL CONDITIONS.

AS THE ARCTIC COLD FRONT PUSHES OFFSHORE AND WINDS BACK NW...FOCUS

SHIFTS TO THE OUTER-CAPE WHERE ITS POSSIBLE GREATER AVAILABILITY

OF MOISTURE AND DECENT FETCH ACROSS THE WATERS WILL YIELD OCEAN-

EFFECT SNOW AND ACCUMULATIONS UPWARDS OF 2-INCHES AS WE GO INTO

THE OVERNIGHT PERIOD. CONTINUE TO MONITOR THE POTENTIAL AND

WHETHER ADVISORIES WILL BE NEEDED.

WITH TEMPERATURES / DEWPOINTS ... LEANED ON THE COLDER SIDE OF

GUIDANCE WITH A BLEND OF THE NAM / MET WITH GREATER WEIGHT LEANED

ONTO THE MET GUIDANCE. HIGHS ONLY GETTING INTO THE LOW- TO MID-20S

WITH UPPER-TEENS ACROSS THE HIGHER TERRAIN. COUPLED WITH THE WINDS

BACKING NW BEHIND THE FRONT...COLDEST WIND CHILL VALUES TOWARDS

DUSK WITH READINGS SEVERAL DEGREES BELOW ZERO FOR THE HIGH TERRAIN

WITH SINGLE DIGITS ABOVE ZERO ELSEWHERE.

WINDS ... ON TRACK. ALREADY BECOMING BREEZING WITH THE DIURNAL

MIXING ONGOING ACROSS THE REGION SUBSEQUENT TO MOSTLY CLEAR TO

PARTLY CLOUDY CONDITIONS. SEEING MIX-DOWN OF MOMENTUM FROM WINDS

ALOFT. EXPECTING GUSTS 25 TO 30 MPH BY MIDDAY...GUSTS 30 TO 35

MPH BY DUSK. IN BOTH SITUATIONS...WINDS WILL BE 5 TO 10 MPH

What's up with that 10F spike at ORH between 8-9am? That looks wrong. 22F at 9am when everyone else including BOS wasnt that warm. Then it dropped back to 18F this past hour after another jump to 24F at 10am.

Thermo looks like it wet haywire but corrected back this hour. We might get a bogus high temp tho if the real temp doesn't hit 24 which it probably won't.

JetBlue taxied too close to the sensor?

I have had pixie dust off and on for a bit.

..snow squalls will move across southern new england this

afternoon and evening...

snow showers in eastern new york will move across southern new
england this afternoon and evening. these snow showers will
produce brief wind gusts to 35 mph, and may briefly reduce the
visibility to less than one-half mile. accumulations of less than
an inch are possible.

here is the expected timing of the showers...
berkshire east slopes, 1 to 130 PM
connecticut river valley, 130 to 230 PM
worcester hills... 2 to 3 PM
northeast connecticut/northwest rhode island, 230 to 330 PM
boston-providence corridor, 3 to 4 PM
cape cod and islands... 430 to 6 pm.

the brief bursts of snow and wind and reduced visibility may
produce hazardous travel. motorists should caution and slower
travel speeds in and near any of these snow squalls.

Heavy snow at Morrisville-Stowe as it moved through...

 

KMVL 071654Z AUTO VRB06KT 1/4SM +SN VV010 M09/M12 A2971 AO2 SLP077 P0000 T10941122 TSNO

 

Got a quick inch at home, but we've had 3.5" at 3,000ft since 4pm yesterday...so definitely some elevation gradient and spine enhancement going on.

 

Here's the view at home at the tail end after a quick 1" of refresher fluff.

Just periods of sn- so far.  Solid overcast though, so maybe we can get a burst or two.

 

15.0/9
