.WHAT HAS CHANGED...
Monitoring early morning shower and embedded thunderstorms 
across southern New England, though storms aren't anticipated to
become severe.

&&

.KEY MESSAGES...

- Scattered showers and thunderstorms remain possible today and
  Friday.

- Dry, seasonable, and comfortable weather returns for the 
  weekend.

- Rain chances return late Sunday into Monday, followed by  
  quieter weather into the middle of next week.

.DISCUSSION...
KEY MESSAGE 1...Scattered showers and thunderstorms remain possible 
today and Friday.

Monitoring a cluster of showers with embedded thunderstorms south of 
I-90 early this morning, mainly impacting Connecticut as of 0530Z. 
While storms remain sub-severe, they are producing lightning and 
localized wind gusts up to 40 mph. This complex of showers and 
storms will move east toward Rhode Island and southeastern 
Massachusetts prior to sunrise, leading to a wet start for the early 
morning commute. However, multiple runs of the HRRR overnight have 
shown the potential for a secondary cluster of showers and embedded 
thunderstorms to redevelop across eastern Connecticut, Rhode Island, 
and southeastern Massachusetts from 09Z to 12Z. Otherwise, expect a 
cloudy start to the day.

Clouds disperse this afternoon with daytime heating and mixing 
within the boundary layer, allowing temperatures to warm into the 
lower to middle 80s. Storm coverage this afternoon remains limited. 
As mentioned by the previous forecaster, the mid-levels are dry with 
northwest flow. Outside of a few hit-or-miss showers, the afternoon 
is largely dry as the better forcing remains associated with the mid-
level trough and shortwave across northern New England. By late this 
evening, the first cold front moves offshore, with a secondary surge 
of drier air reinforcing on Friday. CAMs try to initiate a few pop-
up storms along the edge of this boundary, but given the dry air in 
place, don't expect anything more than isolated coverage of garden-
variety thunderstorms. The vast majority of southern New England 
remains dry, with lower humidity and highs in the lower 80s.

KEY MESSAGE 2...Dry, seasonable, and comfortable weather returns for 
the weekend.

Quiet weather-wise this weekend as an area of high pressure 
originating from northern Canada settles across the Northeast for 
Saturday and the first half of Sunday. PWATs lower quite 
dramatically, with values between 0.5 and 0.7 inches, or nearly one 
standard deviation below normal. Thus, little to no humidity is 
expected Saturday, and conditions may actually feel quite dry, with 
almost fall-like humidity. Temperatures remain near seasonable 
levels, ranging from the upper 70s to lower 80s. Saturday night into 
Sunday morning, clear skies and light winds provide favorable 
conditions for effective radiational cooling. Lows tumble into the 
mid-50s, while urban centers hover near 60 degrees. On Sunday, high 
pressure exits as a low pressure system approaches from the Great 
Lakes region. Warm air advection ushers moisture northward from the 
southwest with the passage of a warm front, resulting in increasing 
cloud cover through the afternoon. Temperatures remain seasonable 
and similar to Saturday, though dew points increase to near 60 
degrees.

KEY MESSAGE 3...Rain chances return late Sunday into Monday, 
followed by quieter weather into the middle of next week.

The next opportunity for rainfall comes during the second half of 
Sunday into Monday. However, there remains uncertainty regarding 
rainfall amounts, as the best forcing is associated with the surface 
low and track variability makes it difficult to pin down where the 
greatest rainfall will occur. This is worth monitoring, as global 
guidance is in agreement that PWATs may exceed 2 inches, indicating 
the potential for heavy rainfall. This is also supported by a 
Marginal Risk (level 1 of 4) for excessive rainfall. Global 
ensembles highlight areas north of I-90 as having the greatest 
likelihood for measurable rainfall, with a 40-60 percent probability 
of at least a half inch of rain between Sunday evening and Monday 
evening. That said, if rainfall becomes more convective, localized 
totals could be higher. One positive is that this system appears 
progressive, with the cold front clearing east of New England on 
Monday. Drier air then advects in from the northwest, leading to 
another dry stretch from the latter half of Monday through Tuesday 
and Wednesday as surface high pressure builds back into the region. 
During this time, temperatures are expected to remain seasonable, 
with highs in the lower to middle 80s and tolerable humidity as dew 
points remain in the lower 60s.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Forecaster Confidence Levels...

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

Today...Moderate confidence.

Leftover SCT/BKN VFR/MVFR decks should begin to scatter out 
between 15-17Z, increasing the risk for SHRA/TS, mainly north of
the Mass Pike, as a sfc cold front moves through. Coverage 
looks spotty but will need to monitor with later updates. Winds
SW to W under 10 kt, then shifting to WNW/NW at 5-10 kt after 
20Z.

Tonight...High confidence.

Any lingering SHRA dissipates early, with VFR conditions prevailing 
thereafter. NW winds 5-10 kt.

Friday...High confidence.

VFR. Low probability of an isolated afternoon thunderstorm across 
interior southern New England; otherwise, dry. NW winds 8-12 kt.

KBOS Terminal...High confidence.

KBDL Terminal...High confidence.

Outlook /Friday Night through Monday/...

Friday Night through Saturday Night: VFR. 

Sunday: Mainly VFR, with local MVFR possible. Breezy. Chance
SHRA.

Sunday Night: Mainly VFR, with local IFR possible. Breezy.
Chance SHRA, slight chance TSRA.

Monday: VFR. Breezy. Chance SHRA.

.MARINE...
Forecaster Confidence Levels...

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

Through Friday...High confidence.

Early morning showers and embedded thunderstorms across the southern 
waters off the coasts of Rhode Island and southeastern Massachusetts 
today will clear by mid to late morning. SW to SSW winds are 
expected today, with gusts around 20 kt. Winds shift to the NW 
tonight at 10-15 kt and continue through Friday, along with dry 
conditions. Seas will remain below 3 ft throughout the forecast 
period.

Outlook /Friday Night through Monday/...

Friday Night: Winds less than 25 kt. Slight chance of rain
showers. 

Saturday through Saturday Night: Winds less than 25 kt. 

Sunday: Winds less than 25 kt. Slight chance of rain showers. 

Sunday Night: Low risk for Small Craft Advisory winds with
gusts up to 25 kt. Local rough seas. Chance of rain showers,
slight chance of thunderstorms. 

Monday: Low risk for Small Craft Advisory winds with gusts up
to 25 kt. Seas up to 5 ft. Chance of rain showers, slight
chance of thunderstorms.
