ANZ200 104 Am Edt Fri Jun 14 2024

Synopsis for massachusetts and rhode island coastal waters - High pressure provides dry weather and southwest winds through Friday. Then very late Fri into Fri night, an approaching cold front will be accompanied by scattered showers and Thunderstorms, possibly accompanied by strong winds, downpours and frequent lightning, especially near shore. Saturday morning a few showers may linger, before the cold front exits offshore Saturday afternoon. Meanwhile, a tropical low will likely track southeast of the 40n/70w benchmark Saturday, then across eastern georges bank Sat night and finally out to sea. High pressure builds over new england Sunday, then offshore Monday. This will yield a prolong period of ssw flow next week along with a very warm airmass.

SYNOPSIS
Warm and muggy Friday with dewpoints in the 60s. Scattered severe thunderstorms possible with the passage of a cold front Friday afternoon and evening. Canadian high pressure will provide a comfortable Father's Day weekend along with dry conditions. Turning unseasonably hot next week as an anomolous mid-level ridge develops across the eastern third of the country. Prolonged period of heat and humidly could linger well into the end of next week.

NEAR TERM /UNTIL 6 AM THIS MORNING/
Pleasant conditions are expected through the overnight with early summer like humidity building into the region on southwest flow. While dewpoints are already in the mid 60s along the south coast and Islands, dews will continue to climb overnight to similar values region wide. Given high dewpoints and SW flow, saw a bit of marine stratus flirt with Nantucket and Block Island around the lunch hour. Low status and fog have been slow to form this evening, thus confidence in it occurring is starting to decrease. Will continue to monitor trends as the night continues. Fog will be hard to come by away from the immediate coast given gusty winds, with 925mb LLJ of around 25-30kt, keeping gusts elevated between ~07-12kt overnight.

Temps have been slow to fall this evening still in the low to mid 70s for most. Still thinking lows reaching the mid 60s is reasonable given clear skies and decreasing winds as the boundary layer decouples from the surface.

SHORT TERM /6 AM THIS MORNING THROUGH 6 PM SATURDAY/
With overnight lows only bottoming out in the mid 60s, temperatures will very quickly warm into the 80s by late morning, which will provide a sounding board for convection driven by a cold front/shortwave crossing the region tomorrow afternoon/evening. As mentioned by previous shifts, we continue to favor a more linear convective line compared to discrete cells given deep layer shear between 30-40kt.

The 12Z HRRR provided a window of greatest certainty regarding when the convective line will begin to impact our northwestern zones, but uncertainty remains between individual members, with the ARW and FV3 firing off storms as early as 16Z and the NAMNest delaying the convective potential until as late at 19Z across western MA and Central CT. While forcing continues to look robust with generous height falls and reasonably strong jet dynamics, tomorrow's convective potential will rely heavily on a narrow band of instability and timing of the line.

So, lets talk instability. Hi-res and global sounding continue to portray a rather significant amount of uncertainty regarding how much fuel will be available. The RAP, perhaps one of our most aggressive pieces of guidance, depicts and environment of MUCAPE values exceeding 2000J/kg ahead of the cold front. Conversely, the NAM and GFS show much more modest instability values ranging from about 600-1200J/kg MUCAPE, with greater instability to our north and west across VT and NY. The best lapse rates will also be to our north and west, but model soundings show that MLLR may exceed 6.5C/km across the western half of the CWA tomorrow afternoon (which, for southern New England isn't too shabby).
MLLR wane quickly approaching the I-95 corridor where they fall to about 6C/km along the I-495 corridor and less than 5.5C/km SE of I-95. Given the gradient in both instability and lapse rates, do expect a rather robust line of convection that will reach approximately the Worcester area between 22-00Z tomorrow evening before the line wanes quickly as it progresses eastward. There remains a distinct possibility that storms decay so quickly tomorrow evening that places from Boston to Providence, south and east, see just some light to moderate rain with any convection dissipating before moving into the more stable airmass. DCAPE values climbing to near 700J/kg and robust low level lapse rates continue to pinpoint strong to damaging wind gusts as the primary severe threat with the convective line. Temperatures aloft remain too mild for a substantial hail threat and near zero helicity/0-1km shear quells any tornado concerns.

PWATs have trended downward compared to yesterday, dropping from ~1.7-1.8" to around 1.5", which is a trend that will, combined with the lack of training storms, mitigate widespread flooding. Still, "long skinny CAPE" is supportive of downpours, depicted by the HRRR PMM that highlights pixels of 1.5-2", especially across the CT River Valley, in some convective cells tomorrow afternoon, which could generate urban and poor drainage flooding in places like Springfield and Hartford.

While the primary convective line will wane after sunset, trailing weak surface low/mid level shortwave will allow some showers to backfill across the region tomorrow night through early Saturday.
Models are poorly depicting how robust these lingering showers will be, but ultimately expect them to shift southeast of the region by 12Z. Trough axis clears the region around the same time which will allow much drier airmass to filter into the region.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Highlights:

* A few showers possible Saturday morning, otherwise a dry and comfortable Father's Day weekend.

* Seasonably warm on Monday, becoming hot and humid Tuesday through the end of next week with heat indicies potentially reaching between 95F and 104F.

* Early summer heat could challenge daily record high temperatures.

Father's Day Weekend...

Few showers linger Saturday morning, mainly across southeastern Massachusetts and Rhode Island as a mid-level trough moves east and away from the region. By no means a washout for Saturday, PWATs fall dramatically as Canadian high pressure moves into the area. This yields a comfortable air mass, dewpoints fall from the 50s into the 40s! As for highs, low to mid 70s near the coast and upper 70s to low 80s inland. Overnight into Sunday morning will be cooler, given the dry atmosphere and weaker wind fields, should have effective radiational cooling for many locations, thus have deviated away from the NBM and favored the cooler MAV and MET blend. Areas like KORE could experience morning lows in the low 40s! Elsewhere, low temperatures are expected to drop to the upper 40s and low 50s along the coast, the exception would be Boston, where lows are generally in the mid 50s. Comfortable conditions follow on Father's Day, with mainly sunny conditions thanks to high pressure, low humidity values and highs in the mid 70s to 80 degrees.

Next Week...

As advertised, we continue to expect well above normal temperatures heading into next week. Starting Monday, mid-level high pressure should be located over the southeast, leading to increasing mid- level heights across the northeast. Could be a rouge shower Monday afternoon with shortwave energy passing to our north, albeit a low chance at this point. Highs warm into the low and middle 80s.

Tuesday into Thursday, the mid-level high expands into the northeast with continued signals this will be an anomolous event. NAEFS ensemble situation table indicates the 500mb heights and surface temperatures could exceed forecast model climatological reference points, in addition to PWATs nearing 97th to 99th percentile!

So, hot and humid conditions are expected with peak intensity around Wednesday and Thursday. Given this is still a week away, there is still time to iron out off the wrinkles/details. Additionally, there are high probabilites, greater than 60 percent, that highs could exceed 90 degrees across northern Connecticut, the majority of Massachusetts (away from the southeastern portion of the state, Cape Cod, and the Island), and northern Rhode Island starting Tuesday, with the peak Wednesday, Thursday, and Friday. It is not out of the question a few spots could reach 100F from Wednesday to Friday.
There are low probabilities on DESI, around 20 to 40 percent, for areas such as the northern Connecticut River Valley and Merrimack Valley. Likely will challenge daily record highs, see the climate section for those details.

This period appear more dry than not, but with a juiced up atmosphere and a few bouts of shortwave energy passing through, can't rule out pop-up showers during this period as well.

AVIATION /06Z FRIDAY THROUGH TUESDAY/
Forecast Confidence Levels:

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

Today: Moderate Confidence

VFR with gusty SW winds to start today. Still some uncertainty with how thunderstorms evolve today with some guidance showing weak thunderstorms developing by 16 to 17z and moving east.
Higher confidence in thunderstorms to develop around 19 to 20z over the Berkshires and begin moving east through the evening.
The highest confidence in thunderstorms is at the BDL, BAF, and ORH between 20-23z. Further east, still some uncertainty on how well thunderstorms will hold together for BED, BOS, and PVD between 22-02z. FMH, HYA, and ACK should only see rain showers but not out of the question for embedded thunder after 00z.

Tonight: Moderate Confidence

Showers begin to taper off after 00z in the west and 06z in the east. MVFR/IFR possible across eastern terminals.

Tomorrow:

VFR with northerly winds at 10-15 knots.

KBOS TAF...Moderate confidence in TAF.

VFR with gusty SW winds to start today. Low chance for a shower or weak thunderstorm between 17z-20z, otherwise the main event thunderstorms shouldn't arrive until 21 to 22z and could last to 01 to 02z. Light rain showers continue behind the thunderstorms through about 06z before tapering off.

KBDL TAF...High confidence in TAF.

VFR with gusty SW winds to start today. Strong thunderstorms are likely starting 20/21z through about 23z/00z.

Outlook /Saturday Night through Tuesday/...

Saturday: VFR. Slight chance SHRA.

Saturday Night through Tuesday: VFR.

MARINE
Forecaster Confidence Levels:

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

Tonight through Friday Night...

Areas of marine stratus and fog are possible overnight into Friday morning, this likely will reduce visibilities to less than one-half mile at times. Surface high pressure moves off shore Friday afternoon with the approach of a strong cold front. Ahead of the front, periods of gusty south/southwest winds produce locally stronger gusts, around 25 knots, for the northeast waters off the coast of Cape Ann. Have held off on issuing a SCA at this time, do think the window for this to occur is during the early afternoon, if confidence in stronger gusts increases a SCA may become needed.
Showers and thunderstorms possible Friday afternoon and evening, with rain lingering into Saturday morning. Seas tonight into Friday are between 2 and 3 ft, but building to 3 to 4 ft for northeast waters, with potential to reach 5 ft on the outermost waters. Seas diminish Friday night into Saturday to around 2 to 3 ft.
Outlook /Saturday Night through Tuesday/...

Saturday: Winds less than 25 kt. Seas locally approaching 5 ft.
Chance of rain showers.

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

Sunday: Winds less than 25 kt. Seas locally approaching 5 ft.

Sunday Night through Tuesday: Winds less than 25 kt.
