Area Forecast Discussion National Weather Service Boston/Norton MA 437 AM EDT Fri Apr 3 2020

SYNOPSIS. A large and intense ocean storm east of New England will begin to move south today before passing north of Bermuda Saturday. This storm will bring strong to damaging winds, coastal flooding and locally heavy rainfall to east coastal Massachusetts and the Cape and Islands today. Occasional rain persists tonight in eastern New England before diminishing Saturday. A weak weather system and front will bring scattered showers Sunday afternoon and night. Unsettled conditions will linger as a few fast moving systems push across the region from Monday night through mid week.

NEAR TERM /UNTIL 6 PM THIS EVENING/. Large ocean storm moving west will begin to turn south and make its closest approach to Nantucket this morning, passing just E of the 40N/70W benchmark then continuing south through today.

60 kt low level jet north of the low will push south from the Gulf of Maine and impact eastern MA today. The core of the jet arrives this morning and persists into the afternoon. Boundary layer is shallow but sufficiently mixed to support max gusts to 60 mph from Cape Ann to the outer Cape and Nantucket, with up to 50 mph gusts across rest of east coastal MA. We expanded the high wind warning to include Cape Ann which will be in the core of this jet, and also expanded the wind advisory from Boston south to western Plymouth county. Less wind further west, 30-40 mph along and west of I-95.

Bands of rain will continue to rotate west across SNE today, but will be focused across eastern MA within the core of the low level jet, with improving conditions developing in the CT valley this afternoon.

See coastal flooding section below for a discussion of coastal flood potential.

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

Storm moves well south of New Eng tonight while SNE remains within the cyclonic circulation. The low level jet weakens but the core of the jet will remain focused across eastern MA where deep moisture persists. As a result, expect occasional rain to continue at times across eastern MA. Hi-res guidance suggests potential for total rainfall of 1-2 inches focused from Plymouth county to Cape Cod.

Winds will slowly diminish as the jet weakens but still a windy night along the coast. Gusts 35-45 mph along the immediate coast gradually diminishing overnight.

Saturday .

Cyclonic NE flow near the coast and persistent moisture will continue the risk of showers across eastern MA, but improving conditions in the afternoon. Lots of low level moisture will result in low clouds persisting, but should become partly sunny in the CT valley. Winds still gusty along the coast in the morning but diminishing in the afternoon as low level wind field weakens and moves to the south. Highs ranging from the lower 40s east coastal MA to low/mid 50s CT valley.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/.

Highlights .

* Dry conditions expected Saturday night into Sunday morning as high pressure moves across

* A weak disturbance and associated cold front will bring scattered showers Sunday afternoon and night

* Dry and mild conditions briefly return on Monday, then will cool to near or slightly below normal cooling through mid week

* A few fast moving systems may bring unsettled conditions from Monday night through mid week

Details .

Saturday night through Sunday night .

As the ocean storm finally shifts E-SE across the western Atlc, expect dry conditions into Sunday. Will still see gusty NE winds up to 20 to 30 mph lingering across Cape Cod and along the S coast Saturday evening, then will diminish as the pressure gradient relaxes and winds become light northerly mainly around and after midnight. Will still see a layer of low to mid level moisture linger as seen on 00Z NAM/GFS BUFKIT soundings, so expect mostly cloudy skies but should remain dry at ground level.

Will see colder air aloft shift southward during the night, with H85 temps down to -2C to -4C after midnight. Expect temp to bottom out manly in the 30s, though could be close to 40 across the lower CT valley.

High pressure ridge will cross the region on Sunday, though may still see low level moisture and clouds will linger across the interior. May see another weak system approach during the day, which may bring some isolated showers as suggested by the 00Z GFS BUFKIT. Have limited any POPs to slight chance mainly across the higher terrain of N central and W Mass. May see a better shot for showers Sunday night as a cold front approaches. Several 00Z model members suggest that the mid level steering flow will become more progressive, so the front should push steadily across Sunday night,

Monday .

00Z model members continue to signal a dry and mild day for Monday as another high pressure center crosses the northeast during the day. As clouds move offshore through the morning, should see quite a bit of sunshine as well. Expect H925 temps to rise to +5c to +7C during the afternoon, so should see temps rise to the lower 60s across interior E Mass and N central/NE CT to the CT valley, but will be cooler along the coast and across the higher terrain.

Tuesday through Thursday .

Lower than average confidence during this timeframe as the fast moving, progressive mid level steering flow remains across the lower 48. Noting rather wide model solution spread amongst the model suite as a few systems push across.

High pressure will push E through Tuesday, then another frontal system approaches as a cutoff H5 low dives SE out of central Canada. This flow may linger through Thursday with a few more systems moving across keeping unsettled conditions in place. Temperatures should run close to or slightly below normal during this timeframe.

AVIATION /09Z FRIDAY THROUGH TUESDAY/. Forecaster Confidence Levels .

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

Through 12z . Mainly MVFR with areas of IFR Cape Cod. VFR cigs CT valley will trend toward MVFR. Bands of rain rotating west across the region, focused across eastern New Eng. N wind gusts increasing to 40-45 kt by 12z outer Cape and ACK.

Today . Moderate confidence. MVFR/IFR conditions in periods of rain, focused across eastern half New Eng. MVFR/VFR cigs CT valley. NE gusts 35-45 kt east coastal MA with up to 50 kt outer Cape Cod and Cape Ann. 25-35 kt gusts along and west of I-95.

Tonight . Moderate confidence. Widespread MVFR/IFR. Occasional rain eastern New Eng gradually diminishing. NE gusts 30-40 kt in the evening, gradually diminishing overnight.

Saturday . Moderate confidence. MVFR/IFR to start gradually improving during the afternoon with VFR developing in the CT valley. Threat of showers persisting across eastern and SE MA. NE gusts 25-30 kt along the coast diminishing in the afternoon.

KBOS Terminal . Moderate confidence. Mainly MVFR cigs but may drop to IFR at times. NE gusts peak around 40 kt today.

KBDL Terminal . Moderate confidence. Cigs lowering to MVFR.

Outlook /Saturday Night through Tuesday/ .

Saturday Night: Mainly VFR, with local IFR possible. Breezy.

Sunday: Mainly VFR, with areas MVFR possible.

Sunday Night: Mainly VFR, with local MVFR possible. Breezy. Slight chance SHRA.

Monday through Monday Night: VFR.

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

MARINE. Peak of the wind from large ocean storm occurs today as low level jet moves south from the Gulf of Maine. NE gusts to 50 kt eastern waters and gusts to 40 kt RI coastal waters. Seas build to 15-25 ft over eastern MA waters. Expanded the storm warning to Mass Bay which will be in the core of the low level jet. Winds gradually diminish tonight and Saturday but it will be a slow process with gales persisting on waters tonight then dropping to SCA during Sat from north to south. Vsbys reduced in occasional rain and fog, improving Sat.

Outlook /Saturday Night through Tuesday/ .

Saturday Night: Winds less than 25 kt. Rough seas up to 11 ft.

Tuesday: Winds less than 25 kt. Areas of seas approaching 5 ft. Slight chance of rain showers.

TIDES/COASTAL FLOODING.

Today .

Powerful low pressure (~ 976 mb) over Georges Bank this morning continues moving west bound, making its closest pass to Nantucket around 8 am this morning, about 100 miles east of the Island. The low will then move southwest tracking near the 40N/70W benchmark this afternoon and then finally southeast out to sea. Strong low level northeast jet associated with this low is currently over the northern ME waters with Mt. Desert Rock reporting a peak wind (NNE) at 56 kt/64 mph at 2 AM! This core of strong NNE winds will coincide with this morning's high tide in eastern MA (730-830am). Thus expecting wind gusts approaching 60 mph along the eastern MA coastline during high tide. This will result in about a 3-3.5 ft storm surge. At 3 AM, already seeing observed surge values of 2.85-2.95.

As for surge model guidance, ESTOFS remains unusable as for whatever reason this model is just not capturing current surge values. ETSS is fairly good with current surge values only running about 0.5 lower than observed values. Stevens Institute ensemble surge SNAP-Ex almost spot when comparing observed surge values to ensemble mean forecast. Thus will continue to follow this guidance very closely. This supports storm surge values ranging from about 2.8 ft to 3.2 ft during this morning's high tide. This brings storm tides (total water level) to about 6.4 ft at Nantucket (flood stage 5 ft) and Boston to 12.5 (flood stage 12.5 ft). These water levels at or above flood stage combined with large waves of 15-20 ft just offshore (up to 25 ft farther offshore) will be sufficient for widespread minor coastal flooding along the entire eastern MA coastline from the NH/MA border southward to Boston to Cape Cod and the Islands. Embedded areas of moderate coastal flooding are possible as these retrograding lows combined with higher period waves from a long NE fetch sometimes result in a greater impact. This includes possible minor structural damage to seawalls and other coastal structures along with minor to moderate beach erosion.

Tonight and Saturday .

Despite the ocean storm moving away from the region later today the following two tide cycles tonight and Saturday morning may experience minor coastal flooding. Thus later today a coastal flood advisory may be needed for these two tide cycles.
