Area Forecast Discussion National Weather Service Boston/Norton MA 651 AM EDT Sat Sep 18 2021

SYNOPSIS. As Tropical Storm Odette passes far to southeast of southern New England today, skies will brighten from west to east. But a cold front will trigger scattered showers or thunderstorms toward evening, from northwest to southeast. High pressure builds in Sunday and will bring sunny and dry conditions from Sunday through mid week, with a warming trend. An approaching cold front will be accompanied by showers and possible thunderstorms from Wednesday night through Thursday night, followed by a drying and cooling trend Friday.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

650 AM update .

Low clouds, areas of fog (locally dense in eastern MA & RI) and mist will slowly lift and burn off this afternoon, as TS Odette moves farther offshore, which will promote height rises and mid level flow transitioning to anticyclonic across SNE. Thus, a drying trend and erosion of the low clouds as the morning progresses and especially this afternoon. Fairly warm and moist airmass by afternoon, especially across the interior with highs in the low 80s and dew pts in the 60s. This will yield MLCAPES of around 1000 j/kg. This instability coupled with modest lift from approaching s/wv, will generate a line or broken line of thunderstorms late this afternoon and evening, roughly 5 pm to 11 pm from northwest to southeast. Deep layer shear is lacking and given instability is only modest, not expecting storms to become severe, but something we will have to watch. Earlier discussion below.

=====================================================================

Mid-morning through mid-afternoon .

Expecting fog to gradually lift during the morning. As Odette pulls farther away to the southeast of the region, skies should begin to break up with increasing sunshine from west to east into the afternoon. Overcast cloudiness may linger along the east coast of MA, however. Winds may gust to 20 to 25 mph along the southeast MA and southern RI coasts . with the highest around Nantucket Highs will reach the upper 70s. with lower 80s in the CT River valley, where sunshine will be more prevalent, and mid 70s at the coast with more cloud cover. It will still be humid, with dewpoints still be in the mid and upper 60s.

Late afternoon .

A mid/upper level trough and surface cold front will approach the region from the west. The front has a pronounced air mass change, with K Index values 30 to 34 ahead of it, with 0 or lower behind it. This front will trigger a line of scattered showers and thunderstorms, as it moves into the warm and still humid environment. Not expecting severe weather, however.

It should be noted that we have continued the Rip Risk Statement for today. Due to increased waves and swell, especially on southeast facing shores, there is an increased chance of rip currents on those southeast facing beaches. Rip currents can catch swimmers by surprise and can be deadly.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SUNDAY/.

355 AM update .

The line of scattered showers and thunderstorms may make it as far as the Boston to Providence corridor and then weaken as it moves off the coast in the early evening.

Over most of the interior, skies will be mostly clear and temperatures will fall into the mid and upper 50s overnight.

It is quite subtle, but models show 925 mb winds veering from north to northeast between 6 PM and midnight, which should be enough to allow overcast low cloudiness and fog to move back onshore from Boston southward to Cape Cod and Nantucket. Briefly dense fog may again occur. By midnight, winds turn more to the north-northwest, allowing the cloudiness and fog to move southeastward and eventually off the coast. Due to the cloud cover in eastern sections, low temperatures will be in the lower 60s.

Sunday looks to be the start of several fine late summer days. With high pressure building in, skies should be sunny. Highs will be in the 70s with pleasantly dry dewpoints in the 49-54 range.

LONG TERM /SUNDAY NIGHT THROUGH FRIDAY/.

355 AM update .

Highlights:

* Very pleasant, dry stretch of weather Monday, Tuesday and possibly lingering into Wednesday, with mild days and cool nights

* Showers & T-storms Wed night/Thu, possibly lingering into Fri

Synoptic Overview .

590+ dam ridge along the eastern seaboard provides dry, pleasant weather Mon/Tue and possibly lingering into Wed. Then a high amplitude trough moves across the Great Lakes into the Northeast. However the guidance is split on the timing and evolution of this trough. The ECMWF and its ensembles are slower with the trough passage, maintaining dry weather across the region through Wed. Meanwhile, the GFS and its ensembles are faster/more progressive, with risk of showers as early as Wed. Although, this is a typical fast bias of the GFS and GEFS in the medium range. Also models differ on how cold post frontal airmass will be Fri. GFS/GEFS blast trough thru New England with subzero 850 mb temps across northern NY/New England Fri. Meanwhile, the ECMWF and its ensembles have trough sheared and lifting off to the northeast, with much weaker cold air advection across SNE.

Temperatures .

Maritime airmass yields seasonably cool temps Monday with highs 70- 75 and lows in the 50s. Then airmass gradual warms Tue into Wed with highs 75-80. Real pleasant stretch of weather featuring mild days and cool nights, along with light winds and abundant sunshine each day. Likely still mild Thu ahead of approaching cold front with highs in the 70s and dew pts into the 60s. As mentioned above, uncertainty on magnitude of post frontal cold air advection Fri. Thus will follow a model blend here (which will offset the fast/ progressive bias of the GFS/GEFS) which offers highs 65-70 Fri, lower 70s southeast MA, which is only slightly cooler than normal. Although, a cooler scenario is possible if the GFS/GEFS solutions verify.

Precipitation .

590+ dam ridge along the eastern seaboard maintains dry weather Mon and Tue. As mentioned above, uncertainty/model differences on timing of upstream trough. Given time range here and to offset the fast/progressive bias of the GFS/GEFS in the medium range, we will follow a model blend which offers chance pops from Wed night thru Thu night, followed by a drying trend Fri in the post frontal airmass.

AVIATION /12Z SATURDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels.

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

11Z update: No major changes from previous TAF issuance. Still anticipating an upward trend in cigs and vsbys later this morning and especially this afternoon, as winds shift to more of a NNW direction. Earlier discussion below.

===================================================================

Overall moderate confidence in the forecast today and tonight. High confidence Sunday.

Through mid-morning . Widespread LIFR in central and eastern portions of the region overnight. Visibilities 1 mile or less with several areas down to 1/4 to 1/2 mile. In western MA and northwestern CT, IFR ceilings but visibilities mainly 3 to 5 miles or higher.

Mid-morning through mid-afternoon . Fog lifting and IFR becoming MVFR ceilings in eastern sections. Skies breaking out to VFR in western and central sections.

Late afternoon and evening . VFR western and central sections, but a line of scattered showers and thunderstorms is expected to sweep across portions of MA, northern CT, and northern RI, with local MVFR vsbys. IFR/LIFR overcast cloudiness will move back into the east coast between 22Z-00Z, impacting KBOS, KHYA, KFMH, and KACK until roughly 04Z-06Z.

Sunday . VFR.

KBOS Terminal . Moderate confidence. LIFR through mid morning with vsby 1/2 to 1 mile . slowly improving by mid morning. MVFR conditions expected to develop after 15Z with VFR briefly possible after 20Z. IFR/LIFR redeveloping 22Z-00Z and lasting until 04Z-06Z Sunday.

KBDL Terminal . Moderate confidence.

Outlook /Saturday night through Sunday/

Sunday Night through Tuesday Night: VFR.

Wednesday: Mainly VFR, with areas MVFR possible. Slight chance SHRA.

MARINE. Forecaster Confidence Levels.

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

355 AM update . Generally high confidence in the forecast. Tropical Storm Odette passes far offshore to the southeast today. It is expected to generate enough of a swell, combined with some winds touching 25 knots (especially near the Cape and Islands), and 4 to 7 ft seas . so Small Craft Advisories remain in effect. They have been added for the waters east of Ipswich Bay and for Stellwagen Bank through Sunday. For the waters south of RI, the Advisory is expected to expire Saturday night.

Scattered showers, mainly southeast of Nantucket today. Chance of a shower or thunderstorm this evening. Areas of dense fog over the waters east of Massachusetts through tonight, reducing visibility to less than 1 nm at times.

Outlook /Sunday Night through Wednesday/ .

Sunday Night: Winds less than 25 kt. Areas of seas approaching 5 ft.

Monday through Monday Night: Winds less than 25 kt. Seas locally approaching 5 ft.

Tuesday through Tuesday Night: Winds less than 25 kt. Areas of seas approaching 5 ft.

Wednesday: Winds less than 25 kt. Seas up to 5 ft.

BOX WATCHES/WARNINGS/ADVISORIES. CT . Dense Fog Advisory until 8 AM EDT this morning for CTZ004. MA . Dense Fog Advisory until 8 AM EDT this morning for MAZ004>007- 012>022-026. High Rip Current Risk until 6 PM EDT this evening for MAZ022- 024. RI . Dense Fog Advisory until 8 AM EDT this morning for RIZ001>005. MARINE . Small Craft Advisory until 11 PM EDT this evening for ANZ235- 237. Small Craft Advisory until 6 PM EDT Sunday for ANZ250-254. Small Craft Advisory until 8 AM EDT Sunday for ANZ255-256.
