Marine Weather and Tide Forecast for Lynn, MA

NEAR TERM /UNTIL 6 PM THIS EVENING/
9 AM update...

Rain is pulling away from NE MA as coastal low moves slowly north from the Gulf of Maine. Meanwhile, mid level low moves into Maine this afternoon with additional shortwave energy rotating in from the west. With sufficient moisture in place, expect scattered showers developing from west to east this afternoon. Coastal winds will continue to diminish today but temps will remain well below normal for late May with highs mostly in the 50s, possibly touching 60 near the south coast.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM SATURDAY/
Spotty showers likely linger though the early morning hours Saturday, but not expecting much accumulation out of it. While we'll finally see some dry hours in the late afternoon/evening, skies remain cloudy. Overnight temps tonight into Saturday closer to normal... around 45 for the interior and near 50 for the immediate coast, Cape, and Islands. Saturday highs once again in the high 50s across the CWA, but a chances the more urban areas could reach 60.

LONG TERM /SATURDAY NIGHT THROUGH THURSDAY/
Key Messages:

* Warmer temps and dry weather will mean Memorial Day is generally good for outdoor activities.

* Wet weather returns around mid-week but timing details uncertain.

High pressure should build over the northern Great Lakes Sunday into Memorial Day, before finally moving across New England Tuesday. A low pressure may approach towards Wednesday, but there is large uncertainty in the track and timing.

The persistent upper low over northern New England finally moves into the Maritimes Saturday night into Sunday. Thus begins a stretch of drier weather into early next week. Still some risk for stray showers during the afternoon hours across interior southern New England, but dry weather prevails for most locations Sunday and Monday.

Temperatures continue to slowly rise with each successive day.
It will likely take until Memorial Day before some locations start to break 70 degrees for high temperatures again.

As we move into Tuesday, dry weather continues with the warmest day in a while as the high pressure moves overhead. Beyond that, another trough takes aim at the northeast, increasing rain chances for mid week, but confidence in timing and details is low at this point given model uncertainty.

AVIATION /18Z FRIDAY THROUGH TUESDAY/

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

Through Saturday: High confidence.

Peak of the winds have passed. Gale Warnings started to be replaced with Small Craft Advisories across the southern waters.
Will take a little longer across the eastern MA coastal waters before those can be converted to advisories as well. Rough seas continue into Saturday across the outer coastal waters. There may be a brief lull later tonight, but not thinking it will be of long enough duration to warrant dropping the advisories across the outer coastal waters.

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.
