Synopsis for massachusetts and rhode island coastal waters - Low pressure continues to pusth well south and east of the coastal waters tonight. Gusty northeast winds over the southeastern waters gradually diminish tonight leading to realtively calm winds over the marine zones for Sunday. Seas over the southeastern marine zones remain somewhat elevated in the 4 to 5 foot range but will gradually diminish early next week with high pressure building over the region.

SYNOPSIS
Increasing clouds tonight ahead of an approaching system across the eastern Great Lakes. A few showers possible late tonight with a hit or miss shower on Sunday, not expecting a washout. Another cooler than normal day is expected Sunday. Milder next week with the risk for showers increasing Tuesday into Wednesday, then mainly dry and seasonable toward the end of next week.
NEAR TERM /UNTIL 6 AM SUNDAY MORNING/
1020 PM update...
Mid level low across eastern Gt Lakes with scattered showers lifting across NY and PA. A few of these showers may spill into western MA overnight as the mid level low drifts east with cooling temps aloft. Otherwise, cloud cover will be increasing.
Temps have already dropped into the upper 30s across portions of SE MA where enough breaks in the clouds with light winds, while temps lower 50s in the CT valley. Lows will range from the mid-upper 30s in eastern MA to low-mid 40s elsewhere.
SHORT TERM /6 AM SUNDAY MORNING THROUGH SUNDAY NIGHT/
Highlights:
* Another cooler day with a few showers possible.
Sunday & Sunday Night:
A weak surface low pressure develops around the eastern Great Lakes and moves southeast, promoting shower activity over New York, but a few showers are possible in western Connecticut and Massachusetts.
While the day is mainly dry, an anomolously cold airmass aloft and shortwave pushes across southern New England, the cold pool could trigger a few spot/pop-up showers across all of southern New England as seen on the 12z CAMs. Good news, not a washout, showers will be isolated and brief. Winds are generally out of the southeast, but along the east coast of Massachusetts do think a seabreeze develops which will keep the wind direction out of the east. Another cooler afternoon with highs in the upper 50s and low 60s away from the coast, near the coast temperatures are in the mid 50s. Clearing sky overnight with high pressure settling back into the region, temperatures aloft are increasing, despite the clear sky don't expect low temperatures to be much cooler than the night before, in fact a few degrees warmer int he low and middle 40s.
LONG TERM /MONDAY THROUGH SATURDAY/
Highlights:
* Warming up Monday and Tuesday with afternoon high temperatures near or above 70 degrees
* A coastal low-pressure system is forecast to bring a period of substantial rainfall and gusty winds to the region Tuesday night into Wednesday
* Drying out late week with more seasonable temperatures in the 60s and 70s
Monday and Tuesday
The week begins with an upper-level low and cold pool aloft shifting east of southern New England. Behind this system a broad upper-level ridge will build over the eastern US and replace the anomalously cool air mass currently in place with a warmer and more seasonable air mass for mid-May. 925 hPa temps rise to 10C on Monday afternoon and 15C on Tuesday afternoon. This should support warmer temperatures in the upper 60s on Monday afternoon and low to mid 70s on Tuesday afternoon. Sea-breezes may keep the coastal areas a bit cooler on Monday.
Precipitation chance begin to increase late Tuesday in response to warm advect ahead of a fairly robust short-wave trough advancing over The Midwest/Ohio River Valley. Most areas stay dry on Tuesday, but can't rule out a few spot showers Tuesday evening.
Tuesday night and Wednesday
By Tuesday night, the short-wave over The Midwest will be traversing east with a surface low-pressure system developing at the surface.
This system is forecast to bring a substantial amount of precipitation to southern New England Tuesday night into much of Wednesday. This system appears as though it will take a coastal- storm track south of southern New England. This would presumably support more stable conditions across the region and limit any potential for spring convection. Nonetheless, strong synoptic forcing/FGEN and PWATs approaching 1.5" will allow for precipitation around an inch or greater by Wednesday night. Ensemble probabilities of an inch or greater are about 50 percent across southern New England with a 10 to 20 percent chance of up to 2 inches over the south coast. Accumulations will be heavily dependent on storm track and just how much moisture is available, but confidence is increasing in a substantial precipitation event during this time frame. Winds may be gusty at times as well with 20 to 30 mph gusts possible Tuesday night and Wednesday. Latest guidance supports this system being east of the region by Wednesday night leading to a dry day on Thursday.
Thursday and Friday
Northwest flow behind a departing area of low-pressure will advect a drier air mass over southern New England to end the week. This will support plenty of sunshine on Thursday with highs in the upper 60s to low 70s. A ridge axis overhead should keep the region dry with warm/seasonable temperatures to end the week as well. As the ridge axis shifts east late week, return flow from the south will support increasing cloudiness and precipitation ahead of our next low- pressure system which may bring more precipitation to the region early next weekend.
