Western Mass Weather for March 21, 2019

WINTER STORM WARNINGS HAVE BEEN HOISTED ACROSS SVT WEST OF BRATTLEBORO, AS WELL AS FOR THE NORTHERN BERKSHIRES, AND EASTERN RENNSELAER COUNTY OF NY FOR THE CENTRAL / NORTHERN TACONICS… WINTER WEATHER ADVISORIES HAVE BEEN HOISTED FOR THE HILLS OF WESTERN FRANKLIN AND WESTERN HAMPSHIRE COUNTIES, SOUTHERN BERKSHIRE COUNTY, NORTHERN LITCHFIELD COUNTY IN CT, AND EASTERN COLUMBIA COUNTY OF NY FOR THE SOUTHERN TACONICS… THE WARNINGS AND WATCHES RUN FROM VERY LATE TONIGHT UNTIL NOON ON SATURDAY… SOME AREAS IN SVT TO RECEIVE OVER 10″ OF HEAVY WET SNOW WITH SCATTERED OUTAGES, ALONG WITH NW WIND GUSTS 35-50MPH… UP TO 1″ OF RAINFALL FOR THE LOWER ELEVATIONS OF WMASS, CMASS AND NORTHERN CT… LIGHT SNOW ACCUMULATIONS POSSIBLE EVERYWHERE BY SATURDAY MORNING…
(5:30pm Thursday)

Good evening everybody, today has been fairly mild, cloudy and showery at times, mainly along and west of the CT River.

Low pressure has formed and is deepening over the DelMarVa Peninsula near eastern Virginia.

This storm will track north and then north-northeast toward southern New England.

TONIGHT INTO TOMORROW MORNING
Rainfall will become more widespread tonight around or after 10pm and certainly by midnight and last into the mid mornings hours before becoming showery by late morning.

If our low pressure tracks a bit more east than originally thought based on recent guidance, this may flip some of us above 1500 feet in elevation in the Berkshires and hilltowns of WMass, NW CT, the Taconics and SVT to wet snow with a coating to a couple of inches possible by dawn.

We also can’t rule out some scattered coatings in the high terrain of southwest NH, eastern Franklin County and the northern Worcester hills.

MAJOR UPSLOPE SNOW EVENT POSSIBLE
To be sure this is a very complex situation, because one degree difference half a mile to a mile up, can change from rain to snow, and if that happens during a heavy shower or band of precipitation, accumulation rates can change pretty dramatically.

By mid day Friday, our storm will be tracking through eastern Massachusetts and on up to Maine.

As it tracks northeast through EMass and into Maine, the air above our heads will cool rapidly, and we will see scattered snow showers form over the aforementioned high terrain during the day (possibly mixed with rain in areas 500-1000 feet in elevation), with moderate to heavy rain Friday morning tapering to scattered rain showers in the valley.

Some patchy fog is also possible. Highs will be in the mid to upper 30s in the high terrain, and low to mid 40s in the low terrain.

FRIDAY NIGHT INTO SATURDAY: THE BRUNT
By the time we get to Friday evening and night, we should all be changing to snow showers along and north of the MassPike, with the exception being down into the eastern CT hills, and the western CT hills where rain will change to snow.

As an upper level disturbance moves through the flow, remnant moisture will be lifted both through storm processes as well as orographic processes (i.e. the presence of mountains forcing the lifting of air skyward).

As our low slowly pulls away, high pressure to the west starts to impinge on our pressure fields in southwestern New England, which will cause northwest winds to gust 30-50mph at times Friday night into Saturday.

This will cause upslope snowfall to commence by Friday evening and last through Saturday morning.

It will snow heavily at times.

The consistency of the snow will heavy and wet and it will likely stick to everything.

With the strong gusty northwesterly winds (Wind Advisories will likely need to be raised) blowing on caked tree limbs and power lines caked with heavy wet snow, scattered power outages can be expected in SVT, western Franklin County, the northern Berkshires and central/northern Taconics.

SNOWFALL AMOUNTS
It appears that 4-8″ of snow will fall northern Berkshires, western Franklin/Hampshire Counties, SVT west of Brattleboro, and the central and northern Taconics.

In fact, some areas in SVT may see more like 8-14″ of heavy wet snow, which could extend into the northern Taconics.

Secondary more minor impacts will be felt in parts of Cheshire County, NH, the northern Worcester Hills, the highest elevations of eastern Franklin County, the southern Berkshires, southern Taconics, Litchfield County CT, and the eastern hills of CT. Southern Worcester County and even easternmost Hampden County is included here too.

There we could see more like 1-4″ of snowfall.

Lastly, in the valley areas of the CT River plain down into north-central CT, a coating to inch or so is possible by Saturday noon.

The heaviest snow will fall above 1000-1500 feet on up.

That does it for now, I will be off-page until about 9 or 10pm, but will do my best to answer any questions when I get back, if there are any.

Please let your hilltown/mountain peeps know what’s on the way. Thank you, and have a great night!

WINTER STORM WATCHES CONTINUE IN SVT… WIND ADVISORIES MAY BE NEEDED FOR SOME OF US FOR FRIDAY NIGHT INTO SATURDAY… PLOWABLE SNOW FOR SVT WEST OF BRATTLEBORO, NORTHERN BERKSHIRES, TACONICS, AND WESTERN FRANKLIN COUNTY PROBABLE… ISOLATED OUTAGES POSSIBLE IN HIGH TERRAIN AREAS… PLENTY OF RAIN FOR THE REST OF US…. A SWEET SUNDAE OF A SUNDAY TO LOOK FORWARD TO BEFORE MORE LIGHT SNOW POSSIBLE BY NEXT TUESDAY…. (6:50am Thursday)

Good morning everybody, it’s morning time, which means double-dash time.

Jump in we shall *insert high-pitched Yoda trill here*

SUMMARY
–We’re mainly dry east of I-91, with a few showers west of there by late morning
–Highs today will be in the mid to upper 40s
–Some snow showers and coatings are possible at elevations above 2000 feet in NW MA and SVT and ENY
–We’re basically mostly cloudy day with a few sunny breaks, and some showers on occasion
–Rain showers become a bit more numerous this evening and through midnight
–Lows drop into the low to mid 30s
–Rain becomes steadier and heavier after midnight as our upper trough negatively tilts and directs coastal low pressure now over the Carolinas up and into EMass
–A half inch to 1.25″ of rain should fall, more to the east
–This lasts through late morning tomorrow
–At the same time, elevations above 1000 feet will start to change to heavy wet snow overnight tonight and through Friday
–Now, there will be a break or a lull during the day Friday, so snow and rain showers are possible, with mostly cloudy skies in the valley
–Highs will be in the upper 30s to mid 40s
–Friday night into Saturday morning is the main elevation-dependen heavy wet snow event
–Upslope snowfall with northwest moist flow will develop across the Taconics, Berkshires, northern Litchfields, western hilltowns, and SVT, with a more minor echo of the same in southwest NH and northern Worcester County
–This will produce heavy wet snow at elevations generally above 1000 feet as the column cools, and as the mountains ring moisture out of the air
–By noon on Saturday a coating to 3″ is expected in the western Hampden/Hampshire Counties, northern Litchfields, the southern Berkshires and southern Taconics. Eastern Windham County in VT could be included here too
–Coatings to an inch or so are possible in southwest NH and northern Worcester County, possibly in the high terrain of eastern Franklin County as well
–More like 3-7″ is expected in the northern Berkshires, central/northern Taconics, and western Franklin County
–I would say the rest of SVT should see 5-10″ in the high terrain, with more like 3-7″ in the valley where Bennington resides
–NW winds will also gust over 40mph at times, and some isolated outages are possible
–Saturday highs will be in the low 30s high elevations, to near 40 in the valley, with lows in the 20s
–Sunday is sweet! Sunny and highs in the low to mid 50s
–More light snow possible early next week

Have a great day!
