- Showers may linger into Saturday. Otherwise, dry weather

.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.
