Area Forecast Discussion National Weather Service Boston/Norton MA 146 PM EDT Thu Oct 28 2021

SYNOPSIS. Much quieter and mainly dry weather returns today into at least part of Friday. A period of rain along with gusty winds is likely sometime from Friday afternoon into Saturday. Dry and seasonable conditions return for Halloween Sunday and the start of November.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Low pres well E of New Eng will continue to pull further away as high pres builds to the north. Relaxing gradient will result in gradual diminishing winds over the Cape/Islands but still expect 20-30 mph gusts into the afternoon, with gusts below 20 mph elsewhere in eastern MA.

Drier air working in from the north and west will allow for partial sunshine to develop across the interior, but NE flow will maintain abundant low level moisture below the inversion across much of eastern MA/RI where low clouds will linger through the day. Some patchy drizzle is possible over the Cape/Islands.

Highs will be mostly around 50 to lower 50s across region with mid 50s in the CT valley where most sunshine expected.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/. Our region is in between the high pressure over southern Canada and a low pressure moving into the Ohio River valley and the central Appalachians tonight into Friday. Drying trend continues tonight, but only briefly. We could be dealing with an approaching low pressure by late in the day Friday.

Near to slightly below normal temperatures expected. It is possible that low temperatures could be lower than currently forecast should there be less cloudiness. Thinking the shallow moisture layer is still present tonight.

LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/. Highlights .

* A coastal low brings a period of rain and gusty winds Friday night into Saturday. * Showers may linger into the first part of Sunday but it should be dry for trick-or-treating. * Dry and seasonable weather to start November. * Next chance of rain arrives late Tuesday into Wednesday.

Details .

Friday night and Saturday .

Another wave of low pressure will approach from the southwest Friday night into Saturday. At the upper levels, an amplifying closed low will lead to enhanced southerly flow out ahead of the next impulse, with dew points briefing getting into the upper 50s/low 60s and PWATs jumping to almost 1.5 inches, or near the max moving average of SPC sounding climatology for Chatham, MA. Given the dynamics and low level jet, should see a wide swath of 1-2 inches of rainfall. Rain shield moves into our area during the pre-dawn hours from the southwest and spreads northeast during the day. The soaking rainfall will unfortunately make it a washout for the first half of the weekend along with gusty conditions. In addition, a rumble or two of thunder also cannot be ruled out, especially for areas along the south coast as guidance hints at a few hundred joules of CAPE Saturday afternoon into evening.

That said, the wind field and dynamics are not nearly as impressive as the Nor'easter earlier in the week. In fact, while the GFS and EC ensemble guidance tracks the low pressure near the 70W/40N benchmark, the low pressure center does not drop below 1000mb (as opposed to sub-980mb for the recent Nor'easter). And taking into consideration the progressive nature, the primary concern appears to be localized urban and poor drainage flooding. At worst, local creeks could reach bankfull given that grounds are saturated from recent rainfall but overall, not expecting significant flooding concerns given how progressive the system is expected to be. As for winds, ensemble guidance indicates a pretty decent 35-45 kt low level jet. But unlike the powerful Nor'easter that we just experienced, the prevailing wind will be from the southeast, which is generally an unfavorable direction for efficient mixing. Nonetheless, used the NBM 90th percentile to bump up winds to low- end gale force for coastal zones to hint at the potential. Unfortunately, gusty conditions especially on Saturday into Saturday night may hinder power restoration efforts in communities hit hard by the recent Nor'easter.

Sunday/Halloween into Wednesday .

While there may be some showers lingering into Sunday morning, it does look like Sunday should be the pick of the weekend with above normal highs in the low to mid 60s and a mix of sun and clouds. It should be a decent evening with dry conditions for the trick-or- treaters. The dry weather continues into Monday as ridging builds in and the flow turns westerly, which allows the low-levels to dry out. So expect the return of sunshine along with dry weather and slightly above normal temperatures in the upper 50s to mid 60s as we turn the calendar into November. Tuesday looks to be a tad cooler than Monday but dry conditions should continue out ahead of a cold front approaching from the west. Shower chances increase by late Tuesday into Wednesday but it remains to be seen whether we get a glancing blow or a more significant rainfall if a secondary low develops. Still plenty of time to figure out the specifics.

AVIATION /18Z THURSDAY THROUGH TUESDAY/. Low - less than 30 percent. Medium - 30 to 60 percent. High - greater than 60 percent.

Through 00z . MVFR cigs will persist in eastern New Eng with VFR in the CT valley. N gusts to 25 kt over outer Cape/Islands.

Tonight . Moderate confidence. Lingering MVFR cigs over Cape/Islands. Otherwise VFR in the evening, then MVFR cigs redeveloping in eastern MA overnight. Light N wind.

Friday . Moderate High confidence. MVFR cigs central and eastern New Eng. VFR CT valley trending to MVFR in the afternoon. NE wind 10-15 kt.

Friday night . Moderate confidence. MVFR trending to IFR overnight as rain overspreads the region from west to east. E/NE wind 10-15 kt with gusts 25-30 kt developing after midnight along the immediate south coast.

KBOS Terminal . Moderate confidence in TAF.

KBDL Terminal . Moderate confidence in TAF.

Outlook /Saturday through Monday/ .

MARINE. Forecaster Confidence Levels.

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

Winds continue to diminish. Gale headlines remain in place across most of the waters early this morning. Expecting these will be converted to Small Craft Advisories over time today. Made some last second adjustments based on the latest observed trends. Rough seas will take longer to subside, especially across the outer coastal waters.

Outlook /Friday Night through Monday/ .

Friday Night: Moderate risk for Small Craft Advisory winds with gusts up to 30 kt. Rough seas up to 10 ft. Chance of rain showers.

Saturday: Moderate risk for gale force winds with gusts up to 35 kt. Rough seas up to 11 ft. Rain showers.

Sunday: Winds less than 25 kt. Rough seas up to 9 ft. Slight chance of rain showers.

Sunday Night through Monday: Winds less than 25 kt. Areas of rough seas.

TIDES/COASTAL FLOODING. Persistent northerly flow prevented efficient drainage of Nantucket Harbor. Latest observations indicated about a 3 foot surge still lingering there. Coastal flood Warning issued for the morning high tide, but will likely need headlines for the afternoon high tide as well.

BOX WATCHES/WARNINGS/ADVISORIES. CT . None. MA . Coastal Flood Advisory from 5 PM this afternoon to 8 PM EDT this evening for MAZ024. RI . None. MARINE . Small Craft Advisory until 1 AM EDT Friday for ANZ232>235-237. Small Craft Advisory until 4 PM EDT this afternoon for ANZ230. Small Craft Advisory until 8 PM EDT Friday for ANZ231-250-251- 254>256.
