Synopsis for the long island waters and new york harbor.. A nearly stationary front south of long island gradually dissipates tonight into Friday. Low pressure well south of long island moves off the mid atlantic coast Friday, and then northeast within the western atlantic through the weekend, passing well southeast of long island.

Area Forecast Discussion National Weather Service Boston/Norton MA 213 AM EDT Fri Sep 17 2021

SYNOPSIS. Low pressure south of New England will brings lots of clouds to region today, along with areas of fog and drizzle to the area this morning, and a spot shower this afternoon. The low will also generate building waves and surf. As the low moves out to sea Saturday, breaks of sunshine develop along with milder temperatures. High pressure then settles in Sunday into the middle of next week, yielding milder than average temperatures and several days of dry weather. Then a strong cold front brings the region first real taste of autumn by late in the work week.

NEAR TERM /UNTIL 6 PM THIS EVENING/.

2 AM Update .

Most of the 00z guidance 06 hr qpf ending at 06z Fri is too wet when compared to latest radar imagery across SNE and the adjacent waters. Thus, will base today's forecast on the drier guidance such as the HRRR and GFS. Drier solutions seem reasonable given mid level ridging across the area today. BUFKIT time sections reveal lots of mid level dry air, which will likely erode showers as activity comes onshore, especially farther inland where dry air aloft is deepest. Thus, other than spotty drizzle this morning, then a spot shower this afternoon, mainly dry weather prevails.

Mostly cloudy conditions, light onshore winds will result in seasonably cool temps with highs in the 70s. Although, it will feel a bit humid with dew pts in the mid to upper 60s.

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

Friday Night & Saturday .

Skies will finally begin to clear by daybreak on Saturday, but fog will again impact the region as northeast flow persists. Given almost identical conditions to Thursday night, low temperatures will fall into the 60s once again. Dewpoints will be slightly higher across western MA, so even our coolest spots will only fall into the mid 60s.

A tropical system being monitored currently monitored by the NHC is expected to pass to our southeast beginning Friday night. The impacts from this system are expected to be low in southern New England. The primary threat will be choppy surf and rip currents, primarily at our south facing beaches.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/. Highlights:

* Scattered showers with cool and breezy conditions on Saturday before dry and seasonable conditions return on Sunday. * Dry weather and above normal temperatures likely heading into middle of next week with high pressure in control.

* Could have our first real taste of autumn late next week.

Details:

Saturday .

The potential tropical cyclone mentioned in the short-term discussion will track near or just south of the 70W/40N benchmark on Saturday. This would mean best chances of rain across southeast New England, though rains in most areas may prove more intermittent. Otherwise, with onshore flow, expect mostly cloudy, breezy and cool conditions with interval of rain showers along with increased swells and heightened risk of rip currents. While effects and impacts will ultimately hinge on the track and intensity of the cyclone, right now the impacts to Southern New England appear minimal.

As heights rise behind the exiting cyclone, there should be significant improvement on Sunday. Sunshine may even return on Saturday afternoon if the low pressure system is faster to exit. Dew points fall from the 60s into the 40s and with sunshine and seasonable conditions returning, it will feel very comfortable for outdoor activities on Sunday. For reference, normal daytime highs are in the low to mid 70s.

Monday into Wednesday .

Monday looks to feature mostly dry and seasonable conditions with high pressure in control. Then mid-level ridging amplifies over the eastern US, with global guidance ensembles showing 588+ Dm ridge building into Southern New England by middle of next week. With mean 850mb temperatures in the low to mid teens, expect daytime highs to reach the upper 70s to lower 80s, which would be 5 to 10 degrees above climatological normal. Have gone with NBM guidance for now given we are so far out but it is possible that daytime highs will be increased in future updates with southwest flow aloft boosting downsloping adiabatic warming. In fact, the Climate Prediction Center 6 to 10 day outlook features above 80 to 90 percent probability of above normal temperatures. So even as we head into astronomical fall for the Northern Hemisphere (beginning September 22), it will feel more like late August. PWATs look to be slightly below to near normal so expect generally mild days and cool nights given the dry air mass.

Thursday .

There are increasing signs that we could have our first real taste of fall heading into the latter part of the upcoming work week. Some deterministic guidance are showing 850mb temperatures in Celsius crashing from the mid teens to the low single digits, with sub- zero temperatures just north of our area. Trough digging into the Great Lakes will eventually erode the ridge over Eastern US by Wednesday/Thursday time frame. Models still differ on the timing of the front and strength of the dynamics. But it is reasonable to expect a line of showers and thunderstorms out ahead of the advancing cold front. This far out, it is too premature to speculate on the potential for severe weather but it looks increasingly likely that the stretch of above normal temperatures will come to an abrupt end by late in the work week.

AVIATION /20Z THURSDAY THROUGH TUESDAY/. Forecaster Confidence Levels.

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

Cigs slowly lifting this afternoon from LIFR to IFR across RI and eastern MA, and remaining MVFR elsewhere. Other than a spot shower, mainly dry this afternoon. Modest ENE winds, except lighter inland.

Tonight . high confidence on trends, lower on exact timing.

Trending back down to IFR/LIFR regionwide. Patchy fog and drizzle possible along with a few spot showers over southeast MA. Modest NE wind along the coast, lighter inland.

Saturday . high confidence on trends, lower on exact timing.

Any IFR/LIFR early in the morning, trends upward to MVFR/VFR in the afternoon, as winds become northerly. Mainly dry, but a few showers possible late in the day across CT and western-central MA.
