Area Forecast Discussion National Weather Service Boston/Norton MA 142 PM EDT Fri Apr 10 2020

SYNOPSIS. Powerful low pressure over Nova Scotia will maintain cool and blustery weather across southern New England this afternoon, along with scattered showers. Dry weather Saturday but remaining cool and brisk. High pressure south of New England provides milder temperatures for Sunday with highs 55-60. Powerful low pressure then tracks thru the Great Lakes Monday with heavy showers and strong winds to impact southern New England. Dry and seasonable weather returns Tuesday.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

130 pm update .

Considerable cloudiness across the area with scattered rain showers across the area, except more numerous rain/snow showers extending over the Berkshires into the east slopes. Have increased POPs to chance for most of the area, except likely to categorical pops along the east slopes of the Berkshires and far NW Hartford County. Some showers in the area may produce a brief period of small graupel. In the highest terrain of NW MA, we could still have some snow showers, though accumulations are expected to be limited to a few tenths of an inch or less.

The cold pool aloft, wrap around moisture, and lake effect moisture will allow this weather to persist thru the remainder of this afternoon, starting to diminish towards sunset.

Wind gusts 25 to 40 mph expected to continue through this afternoon, just shy of Wind Advisory. Exception is over Block Island, Nantucket and Martha's Vineyard, where a Wind Advisory continues for gusts to 50 mph.

Early Morning Discussion follows .

Today .

Mainly dry conditions this morning with just some lake effect rain/snow showers from NY state spilling over the Berkshires and Litchfield Hills into the CT river valley. Impressive cold pool of -36C at 500 mb streaming S-SW of New England and yielding scattered rain showers currently across northern NJ/NYC into western LI. This activity will track south of New England this morning. As this cold pool moves offshore, wrap around moisture and warmer air aloft (TROWAL) pivoting cyclonically around mid level low into southern New England this afternoon. Thus expect morning sunshine to give way to afternoon clouds and scattered rain showers with scattered snow showers over the high terrain. Not a wash out but definitely have to dodge a few chilly showers/sprinkles this afternoon and early evening.

Cool temps aloft (-5C at 850 mb) combined with mostly cloudy conditions this afternoon will limit highs to 45-50, low 40s in the high terrain. Normal high for April 10th is 52-58, so a few degs cooler than normal but it will feel even cooler given brisk west winds today sustained 15 mph but gusting 25-35 mph at times. Strongest winds will be across the Islands given stronger wind fields aloft and deeper boundary layer with gusts up to 50 mph at times. Therefore have posted a Wind Advisory for Block Island, Marthas Vineyard and Nantucket.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/. Tonight .

Any leftover sprinkles/light rain showers (light snow showers high terrain) during the early evening will move offshore and give way to dry weather. CAA continues with 850 mb temps lowering to about -7C. Lows will be in the 30s but a NW breeze will yield wind chills in the 20s. Strongest NW winds over Cape Cod and Islands with gusts up to 30 mph.

Saturday .

Another northern stream trough moves across the area in the morning but its cold pool remains north of region over northern VT/NH into ME. Thus column not as cold and drier than today. As a result more sunshine Saturday than today yielding temperatures a few degs warmer with highs in the low 50s. Not quite as windy as well with WNW winds 10-15 mph with gusts up to 25 mph. So overall some improvement and more pleasant than today.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Highlights .

* Temperatures running near to below normal Saturday, then a warm up Sunday-Tuesday

* Rain, thunderstorms, and gusty winds on Monday

* Drier and cooler through mid week

Details .

Saturday night and Sunday .

The ridge axis moves overhead Saturday night bringing light winds, clear skies, and efficient radiational cooling. MOS guidance has been given more weight with the low temperatures for this reason; we're looking at most interior locations dipping to near or below freezing.

By Sunday on the back side of the ridge warm SW flow advects in milder air and mid/upper level moisture. So, while clouds will be on the increase through the day, temperatures will be quite a bit warmer than Saturday, in the upper 50s . closer to the low 60s for the CT Valley. The exception, as per usual, will be the Cape and islands where southerly flow off the ocean keeps temps in the low 50s. Also on Sunday a modest 25-35 kt LLJ moves overhead. Given WAA at the sfc, the BL should be well mixed to near 800 mb leading to wind gusts of 25 to 35 mph at the surface. Overall, a mild, partly cloudy, and breezy end to the weekend.

Sunday night and Monday .

Late Sunday night and Monday our next strong storm system will impact southern New England bringing widespread heavy rain, strong winds, and thunderstorms. At the synoptic scale we see the merging to two distinct disturbances; one, a cutoff low spinning over the desert southwest all weekend which is finally pulled into the steering flow Sunday and eventually phases with a digging trough over the northern Plains, lifting through the Great Lakes on Monday. This will be a very strong and expansive system. Global guidance progs the sfc MSLP around 992 mb at 00Z Monday and by 00Z Tuesday its around or sub 970 mb. Jet dynamics are very strong as a result . 850mb jet of 80-90 kts! GEFS ensemble guidance shows v (southerly) component of the jet at 5-6 standard deviations above normal. The EC isn't quite as bullish, but still very strong. Regardless of the exact values, this together with a large moisture plume (PWATs near 1.5" and dewpoints in the upper 50s) and cold frontal forcing will bring widespread heavy rain to the region starting Monday morning and exiting by the early hours of Tuesday. While model soundings show enough of a slight inversion to keep the very strong winds aloft as a whole, heavy downpours could bring strong to damaging winds from aloft down to the surface. Convection likely makes a return as well, with modest elevated instability (200- 500 J/kg CAPE) and strong shear (50-60 kts 0-6 km bulk shear). Thunderstorm chances increase late Monday morning in western MA/CT and move east through the day. The cold front then moves through Monday night into Tuesday morning ushering in a drier and cooler airmass. Rainfall totals look to be from 0.5-1.0" with locally higher amounts possible under heavy downpours.

Tuesday through Thursday .

The low pressure exits into Quebec by daybreak on Tuesday leaving us under a broad east coast trough through mid week. At the surface high pressure edges its way east into the areas helping keep precip away, and suppressing a storm system to our south over the Atlantic on Wednesday. Overall a dry period is expected with the return of cooler temperatures, down into the low 50s by Wednesday. Tuesday will be dry but windy as CAA aids in mixing down some gusty west winds, generally 20-30 mph. By Thursday another trough brings our next shot of rain to the region.

AVIATION /18Z FRIDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels .

Low - less than 30 percent. Moderate - 30 to 60 percent. High - greater than 60 percent.

18z update .

MARINE. Today thru Saturday .

*** Gale Warnings Remain Posted ***
