Area Forecast Discussion National Weather Service Boston/Norton MA 709 PM EDT Fri Jul 3 2020

SYNOPSIS. Showers and a few thunderstorms across western Massachusetts and northern Connecticut will come to an end by early to mid evening. Dry weather is on tap for Saturday, but low clouds and cool temperatures will persist on the coast while a partly sunny and warm afternoon is on tap for interior southern New England. A weak cold front moves through late Sunday/Sunday night which may trigger a few showers or a thunderstorm. Weak high pressure follows Monday, then a warm front approaches Tue with chance of showers/thunderstorms in the interior. Hot and humid conditions move in for the middle and end of next week with scattered afternoon/evening thunderstorms each day.

NEAR TERM /UNTIL 6 AM SATURDAY MORNING/. 710 PM update .

T-storms moving south from SE NY and SW CT along the eastern gradient of the instability axis. Stable environment across BOX CWA. Showers this evening will exit CT and may clip parts of the south coast, otherwise dry most of the night. Some patchy drizzle and fog is possible overnight near the coast with moist NE low level flow, and will have to watch for some showers developing late tonight over the Cape/Islands near elevated instability offshore. Low temps will mainly be in the lower to middle 60s.

SHORT TERM /6 AM SATURDAY MORNING THROUGH SATURDAY NIGHT/. Saturday .

High pressure over the Maritimes and low pressure to our south will maintain low level NE flow. A bit of drizzle is still possible into mid morning along the coast, but the main issue will be low clouds. We should see partial sunshine develop across the interior by afternoon, but it may take until mid to late afternoon for some partial sunshine to emerge across eastern MA/RI. In fact, the Cape/Islands may remain in the low clouds until early evening.

Onshore flow and an abundance of clouds will hold high temps into the 70 to 75 degree range across eastern MA as well as the Cape/Islands. Meanwhile, enough sunshine should push parts of western MA and northern CT into the lower to middle 80s.

Saturday night .

Dry and pleasant weather is expected for Saturday night. Low temps should drop between 60 and 65. Low probability of a shower or two toward daybreak with some elevated instability, but forcing rather limited so maintained a dry forecast. Some patchy fog is possible too.

LONG TERM /SUNDAY THROUGH FRIDAY/. Highlights .

* Few showers/t-storms possible Sunday * Seasonably warm Mon/Tue with shower/t-storm risk interior on Tue * Hot and humid Wed-Fri with sct afternoon/evening t-storms

Sunday .

Mid level shortwave drops across northern ME with 500 mb temps dropping to -12 to -13C. This cold pool combined with surface heating will contribute to CAPES 1000-1500 J/kg. Weak cold front moving across SNE may provide a focus for a few showers/t-storms developing. Guidance is not too bullish on convection so areal coverage may be limited but do expect a few storms which may be focused more in eastern half New Eng based on location of front. 850 mb temps around 16C which supports highs well into the 80s and near 90 degrees in CT valley, but cooler immediate coastline where sea breezes expected to develop.

Monday and Tuesday .

Cold front moves offshore by early Mon with weak high pres building in bringing mostly sunny skies. Low level winds turn easterly which will result in a cooler airmass Mon, especially in the east. Instability axis gets pushed west of SNE so a dry day expected. Highs Mon will range from the 70s eastern MA coast to the mid/upper 80s CT valley. Then on Tue, warm front will move in from the west with risk of sct showers/t-storms in western MA/CT as instability increases in the west. Seasonably warm temps Tue.

Wednesday through Friday .

SNE will be on the periphery of subtropical ridge which will result in increasing heat/humidity moving into the region. Many locations will likely see temps into the upper 80s and lower 90s. Series of weak shortwaves traveling within the nearby polar jet combined with unstable environment will lead to scattered afternoon/evening showers/t-storms each day.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/. Forecaster Confidence Levels .

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

00Z Update .

Tonight . High confidence. Cooling boundary layer tonight allows for conditions to deteriorate to IFR-LIFR levels across central/eastern MA & RI with lowest conditions along the coast. Ceilings lowering to MVFR in western MA/CT. Showers exiting CT this evening and may see some drizzle or a few showers develop overnight along the coast.

Saturday . High confidence. Gradual improvement in ceilings to mainly VFR by mid afternoon from west to east. However, lower clouds may hang tough all day across the far southeast New England coast.

Saturday night . High confidence in mainly VFR conditions.

KBOS Terminal . High confidence in TAF.

KBDL Terminal . High confidence in TAF. Main concern will be heavy showers and embedded t-storms in the vicinity of the terminal through 21-22z.

Outlook /Sunday through Wednesday/ .

Sunday through Sunday Night: VFR. Slight chance SHRA, slight chance TSRA.

Monday: VFR.

Monday Night: VFR. Slight chance SHRA.

Tuesday: VFR. Slight chance SHRA, slight chance TSRA.

Tuesday Night: VFR. Slight chance SHRA.

Wednesday: VFR. Breezy. Slight chance SHRA, slight chance TSRA.

MARINE. Tonight through Saturday night . High confidence.

Marginal NE wind gusts of 20 to 25 knots and 3 to 5 foot persisted late this afternoon, so will maintain SCA headlines across the eastern waters early this evening. Weakening gradient will allow winds/seas to drop below small craft advisory thresholds this evening. NE winds of 10 to 15 knots Sat morning will shift to the south at 5 to 15 knots Sat night as offshore low moves further away from the region. Winds/seas will remain below SCA thresholds Sat and Sat night. Areas of fog tonight and perhaps again Sat night will reduce vsbys at times for mariners.

Outlook /Sunday through Wednesday/ .

Sunday through Sunday Night: Winds less than 25 kt. Slight chance of rain showers, slight chance of thunderstorms.

Monday through Tuesday Night: Winds less than 25 kt.

Wednesday: Winds less than 25 kt. Seas locally approaching 5 ft. Slight chance of rain showers, slight chance of thunderstorms.

BOX WATCHES/WARNINGS/ADVISORIES. CT . None. MA . None. RI . None. MARINE . Small Craft Advisory until 8 PM EDT this evening for ANZ250- 254.
