.WHAT HAS CHANGED...
Gale Warnings posted for the eastern coastal waters as well as
the MA bays and sounds.

&&

.KEY MESSAGES...

- Dry weather for most through Saturday with gusty west winds.

- Summer-like Sunday with comfortable humidity and a risk for
  afternoon showers. 

- Chances for a widespread rain Monday into Tuesday. Drier with
  seasonable temperatures follow for midweek.

&&

.DISCUSSION...
KEY MESSAGE 1...Dry weather for most through Saturday with gusty
west winds.

A low pressure over southeast Canada and a weak high pressure
over the central USA will maintain a westerly flow across New
England through Saturday. Since we will be closer to the low
pressure, expecting gusty winds wind peak speeds up to about 30
mph.

Dry weather persists as well. There is a low chance for a pop-up
afternoon shower or two across northern MA Saturday afternoon,
but many hours will remain dry even there.

Noticeably lower humidity today that should persist into
Saturday. Near to slightly above normal temperatures today,
lower slightly for Saturday. 

KEY MESSAGE 2...Summer-like Sunday with comfortable humidity and
a risk for afternoon showers.

A sheared off mid level shortwave should move through weakly
cyclonic flow aloft Sunday. This is not the most potent forcing
for showers. However, it does appear to be enough where the idea
of typical afternoon popup showers can be dismissed. Thinking
the greatest risk will towards northern MA and northern New
England due to the closer proximity of the cold pool aloft.

KEY MESSAGE 3...Chances for a widespread rain Monday into
Tuesday. Drier with seasonable temperatures follow for midweek. 

We continue to track our next chance for a widespread rainfall
sometime Monday into Tuesday. There are still significant timing
and track differences with this low pressure early next week.
The 19/00Z GFS and ECMWF are on the progressive side. So much 
so, that Tuesday would be dry. The ECMWF was slightly farther
west with its track. On the other side of the solution envelope,
is the 19/00Z Canadian. While it has a more westward track like 
the ECMWF, it is slower with its timing. Will continue to take
an ensemble approach at this point with the timing. This will
focus most of the rainfall from Monday afternoon into Monday
night, followed by drying conditions during the day Tuesday.

Still robust signals in the NationalBlend output, with a greater
than 80% chance for 24-hour rainfall of 0.50 (12.7 mm) or 
greater ending 8 AM Tuesday. Even the probability for a 1 inch 
(25.4 mm) or more is a robust 60-70% during that same time.

Behind this system, high pressure starts to push in from the west, 
bringing a return to drier weather and seasonable temperatures 
through the middle of the work week.
