SYNOPSIS

Sunny and warm today with gusty southwest winds. Warm and muggy Friday with dewpoints in the 60s. Scattered severe thunderstorms possible with the passage of a cold front Friday afternoon and evening. A few spot showers will remain possible across eastern MA/RI into Saturday, but otherwise a dry weekend with cool nights and mild days with much less humidity is expected.
Near record high temperatures along with excessive heat/humidity are possible next week...beginning Tuesday and perhaps continuing through Thursday or Friday.

NEAR TERM /UNTIL 6 PM THIS EVENING/

Key Point

* Sunny and warm with increasing dewpoints

Southwest flow and WAA begins to kick in today allowing for 850mb temps to climb to +15C. With much warmer temps aloft, the convective temp jumps into the mid 80s across the region, meaning the diurnal cumulus will not be as widespread as the previous two days. With mostly sunny skies and WAA, temperatures should be able to reach the mid to upper 80s. Dewpoints will also be on the rise tomorrow into the upper 50s to low 60s.
Winds will become gusty up to 20mph in the afternoon with steep low level lapse rates and mixing potential up to 6-7kft.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/

Tonight

Still under SW flow, dewpoints continue to rise into the low 60s overnight. Even with mainly clear skies, temperatures will stay on the warm side overnight only dropping into the mid 60s. SW winds continue to increase overnight gusting 20mph.

Tomorrow

Key Points

* Warm and muggy start to the day * Scattered severe thunderstorms across western MA and CT

Friday will be a warm and humid day with temperatures quickly rising into the mid to upper 80s and dew points reaching the low to mid 60s. This will help set the stage for scattered severe thunderstorms as a potent shortwave trough and cold front drops SE across the region in the afternoon. As the cold front moves through, a very narrow corridor of instability will be set up across western MA and CT. There is some disagreement among the hi-res guidance on how much instability will be set up with the HRRR only showing 500 J/kg of SBCAPE while the NAM3K shows up to 1200 J/kg. Deep layer shear increases with the passage of the shortwave up to 30-40 knots, supportive of organized linear clusters of severe thunderstorms. Storms likely initiate off the high terrain in Western MA/CT and southern VT shortly after 12pm. Storms then move east through the afternoon, but quickly weaken approaching eastern MA and RI as they run into a more stable environment with less instability and shear. The severe threat at this time looks highest across western MA and CT as highlighted by the SPC slight risk.

Severe threats:

The primary severe threat will be strong to damaging winds with steep low level lapse rates and linear storm mode promoting straight line winds. The hail threat looks very low at this time with very meager mid level lapse rates only between 4-5C/km and the freezing level above 10kft. The tornado threat also appears very low with very little low level shear and linear storm mode will promote upscale growth rather then discrete supercells.

Heavy Rain threat:

Although the storms will be progressive with little to no training expected, PWATS will be increasing into the 1.6-1.8 inches. Long skinny CAPE profiles and warm cloud depths approaching 10kft are supportive of heavy downpours. HRRR 3hr PMM does highlight western MA and CT with 10% probs for greater then 3 inches of rain in 3 hours. This could lead to areas of street and poor drainage flooding along with isolated instances of flash flooding.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/

Key Points...

* Weakening showers/t-storms work towards the south coast Fri evening * A few lingering spot showers possible across eastern MA/RI Sat * Dry & very pleasant Sat night & Sun with low humidity * Excessive Heat/Humidity begins Tue possibly continuing through Fri * Near record highs next week...Heat indices may reach between 95-104

Details...

Friday night...

Scattered strong to severe storms that are expected to the northwest of I-95 into early Friday evening will be weakening on approach and especially southeast of Boston to Providence corridor. Given the loss of diurnal heating coupled with southwest flow and poor mid level lapse rates...instability will be tough to maintain after sunset. So while the activity will probably survive to the Cape & Islands it will be in a weakening form. So expect the severe weather threat to have come to an end.

Some showers may linger into the overnight hours especially across eastern MA/RI. This a result of upper level energy approaching from the west and hints of an inverted trough.

Saturday...

A few low topped showers will remain possible on Sat across eastern MA/RI with lingering upper level shortwave energy/cold pool aloft.
Not expecting a washout and it will be cooler with lowering humidity through the day. High temps will generally be in the middle to upper 70s...but a few spots may approach 80 in the lower CT River Valley.

Saturday night and Sunday...

High pressure building over the region will result in good radiational cooling conditions Sat night...especially with the dry airmass moving into the region for mid June standards. Overnight lows will bottom out in the middle to upper 40s in some of the coolest outlying locations in western MA with mainly 50s elsewhere.
Plenty of sunshine on Sunday will result in highs mainly in the upper 70s to near 80 with low humidity...so quite a comfortable day to close out the weekend.

Next Week...

The main concern continues to be the potential for excessive heat and humidity next week. An anomalous upper level ridge will build northward into southern New England. A warming trend begins on Monday, but the significant heat/humidity potential looks to begin Tuesday and perhaps continue through Thursday or Friday. Timing and magnitude of the heat/humidity are uncertain at this time...but current indications are that it may peak in the Wed/Thu time frame.

There has been a strong signal amongst all the model guidance the last several days. The EPS/NAEFS situational awareness table indicates parameters outside the models climatology which is signal for the potential of a highly anomalous event...in this case heat & humidity. Near record high temperatures will be possible. There are fairly high probs of temps reaching well into the 90s for at least 1- 2 days and perhaps flirting with 100 degrees in some spots.
Afternoon heat indices in the 95 to 104 degree range are possible at times. It will remain quite muggy at night so that will be another concern. We should have a better idea on the magnitude and timing of the heat in the next few days.
