- Dry and seasonable today through much of the day Thursday.
- Risk for scattered showers and a few thunderstorms returns
Thursday evening/night into Friday.
- Showers may linger into Saturday. Otherwise, dry weather
expected through much of the weekend into the start of next

.DISCUSSION...
KEY MESSAGE 1...Dry and seasonable today through much of the day
Thursday.
Rain has continued to pull further offshore of the Cape and Islands
early this morning and will continue to do so as we approach
sunrise. Patchy fog this morning enhanced by the recent rainfall
will also burn off as winds pick back up and the sun rises. With the
wave responsible for this rain continuing offshore and more westerly
winds picking up, expect a sunnier, drier day across southern New
England today with highs in the low 80s and upper 70s. This drier
pattern will last into much of tomorrow as well as high pressure
over much of the eastern US stretched up into the northeast.
KEY MESSAGE 2...Risk for scattered showers and a few thunderstorms
returns Thursday evening/night into Friday. Monitoring for severe
risk Friday night.
Our next chance for rain and some thunderstorms returns Thursday
night as another shortwave approaches and crosses into southern New
England. With the main surface low shifting eastward over the Great
Lakes into southern Ontario, its warm front extends out to its east
and will likely track into the region Thursday night. For much of
these showers, embedded thunder out in western MA is a possibility,
but the risk goes down considerably east of Worcester. The risk for
severe storms developing is low in the morning, though later in the
afternoon/evening it increases ahead of the low's cold front behind
the morning's warm front. Ensemble guidance varies greatly still on
how much instability may be present Friday evening ahead of the
second round of storms, but some models are hinting at stronger
effective shear being present. The forcing from the arriving front
will likely be enough to generate this second round of showers with
some storms possible, but whether these may turn severe is still
uncertain at this time given the lack of a consensus on how much
instability may be present at the same time as these other two
ingredients. Will continue to monitor as we get closer to this
timeframe.
KEY MESSAGE 3...Showers may linger into Saturday. Otherwise, dry
weather expected through much of the weekend into the start of next
week.
Heading into Saturday morning, there may be some lingering showers
around. Another wave of low pressure looks to track to our south
based on the latest guidance, though the chance remains that some
showers could impact the south coast heading into the daylight
hours. Aside from this, dry weather is expected to return heading
into the start of next week as high pressure associated with an
amplified upper level ridge moves into southern New England. A
warming trend also kicks off for the start of the work week,
continuing into midweek. However, details on just how warm it may
get are still uncertain at this time.
