.DISCUSSION...
KEY MESSAGE 1...Prolonged stretch of dry weather across southern New
England, potentially lasting through Halloween. Afternoon
temperatures moderate through tomorrow, followed by a brief
cooldown Tuesday and Wednesday before milder weather returns
late in the week.
Radiational cooling expected once again tonight, though not as cold
as last night given slightly warmer temperatures aloft. 925 mb
temperatures reach around 12C overnight, then continue to improve
through the day Monday a few more degrees (14C). Highs Monday are
expected to reach the upper 60s and some clouds may move in ahead of
an approaching cold front. This cold front is expected to be quite
dry otherwise, given the persistent high pressure and dry air
present. With its passage, winds shift more N to NW heading into
Monday night and a mix of some low to high clouds move in, which
will end up limiting radiational cooling. Lows Monday night are
expected to generally be in the 30s and 40s.
High pressure will continue to govern Southern New England's weather
through the upcoming workweek, leading to a continued stretch of dry
and seasonable autumn weather. We get a brief cooldown on Tuesday in
the wake of the cold front from Monday night; with 925 mb temps
around +2 to +5C, highs mainly in the mid 50s. We get into a
warming/modifying trend to temperatures through the rest of the
workweek. By Thursday and Friday, highs could reach well into the
60s to lower 70s.
Another mostly dry cold front then passes to our north Friday night.
This feature again looks to only bring some enhanced cloudiness for
Friday night, but the chances for rainfall associated with this
feature looks minimal. It will bring another shot of cool air for
the weekend with blustery conditions, with temperatures falling back
into the 50s to lower 60s for the weekend.

Forecaster Confidence Levels...
Low - less than 30 percent.
Moderate - 30 to 60 percent.
High - greater than 60 percent.
Through Monday Night...High confidence.
High pressure remains in control, bringing dry weather and generally
favorable marine conditions for the next several days. Winds
tonight expected to generally be from the W to SW at around 5-12
kt. Seas remain 2-3 ft tonight into Monday. Winds shift more
towards the NW Monday night following the passage of a dry cold
front, reaching up to 20 kt sustained and gusting to 25 kt. For
this reason, a Small Craft Advisory has been issued for the
northern and eastern waters where confidence is highest in this
occurring. Seas may also reach 5 ft in localized spots of the
outer waters towards Tuesday morning.

Tuesday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Seas up to 5 ft.
