.WHAT HAS CHANGED...
Converted Gale Warnings to Small Craft Advisories across the
coastal waters. Canceled the Gale Warnings across the ocean
waters.

&&

.KEY MESSAGES...

- Mainly cloudy with slow warming through Saturday night.

- Prolonged period of dry weather for most if not all of next
  week with chilly nights and mild days. High temps moderate to  
  above normal levels in the upper 50s to the lower 60s for the 
  middle and latter half of next week with perhaps a day or two 
  reaching into the middle 60s in some spots.

&&

.DISCUSSION...
KEY MESSAGE 1...Mainly cloudy with slow warming through 
Saturday night.

Southern New England should remain in a cyclonic flow at the
surface through Saturday night. A mid level shortwave should
approach our region Saturday afternoon, before passing overhead
Saturday night. The question is how much moisture will be
around. Current thinking is there will be more clouds than not.
Cannot completely dismiss the idea of a stray rain or snow
shower towards portions of northwest MA, where upslope flow 
into the Berkshires will also play a role. Eventually, though 
the lower levels should dry out enough where the risk for 
precipitation is nearly nil.

Raised low temperatures from the NationalBlend values due to 
expected cloud cover preventing strong radiational cooling.
North winds become more westerly late tonight into Saturday.
That subtle shift should limit cold air advection, and some
sunshine should contribute to gradually rising temperatures
early this weekend. That said, still thinking temperatures
remain slightly below normal into Sunday.

A Coastal Flood Statement remains in effect for northern facing 
shores of Cape Cod Bay and Nantucket where gusty winds combined 
with astronomical tides may lead to some minor coastal 
flooding/splashover during the hours directly around high tide 
this afternoon.

KEY MESSAGE 2...Prolonged period of dry weather for most if not
all of next week with chilly nights and mild days. High temps 
moderate to above normal levels in the upper 50s to the lower 
60s for the middle and latter half of next week with perhaps a 
day or two reaching into the middle 60s in some spots. 

The long range model guidance is in very good agreement in the
upper trough shifting east of the region early next week. This
will be replaced by upper level ridging/above normal height
fields. The result will be an extended period of dry weather for 
most if not all of next week. High temperatures will moderate
back to above normal levels for the middle to latter portion of 
next week with highs in the upper 50s to the lower 60s. In fact, 
would not be surprised to see temperatures overachieve with some
spots perhaps reaching the middle 60s for a day two. Mainly 
clear skies and light winds will allow for chilly/seasonable 
overnight lows in the 20s and 30s.

So in a nutshell, a dry/tranquil week of weather is in store for 
the region. A large diurnal spread in temps is also expected
with seasonably chilly nights but mild/above normal afternoons.

.AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
Forecaster Confidence Levels...

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

Through 00Z...High confidence in trends, but moderate on timing.

Low pressure slowly moves offshore tonight. VFR CIGS moving
south along the east coast of MA. Lingering moisture towards the 
higher terrain, as well as towards the Cape and islands, should 
maintain MVFR conditions until this evening. Scattered -SHRA,
with the greatest risk towards the Cape and islands. Gusty N to
NW winds should diminish some after sunset.

Tonight: High confidence in trends, but moderate on timing.

Should be starting with VFR, except for terminals in southeast 
MA and RI, with VFR expanding to all terminals by 06z.
Substantial improvement takes place after 06z Sat. North to
northwest winds 8-12 kt with gusts to 20 kt.

Saturday and Saturday Night...High confidence. 

VFR. NW winds 5-10 kts. Diurnal cloudcover bases from 050 to 
060 after 17z. Areas MVFR possible towards the east slopes of
the Berkshires. A stray shower cannot be ruled out there also. 

KBOS Terminal...Moderate confidence in TAF.

KBDL Terminal...Moderate confidence in TAF.

Outlook /Sunday through Wednesday/...

Sunday through Monday: VFR. Breezy. 

Monday Night through Tuesday: VFR. 

Tuesday Night through Wednesday: VFR. Breezy. 

&&

.MARINE...
Forecaster Confidence Levels...

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

Through Saturday Night...High confidence.

Based on recent buoy reports, lowered the Gale Warnings to Small
Craft Advisories across the coastal waters, and canceled the
Gale Warnings across the ocean waters. Gusty winds will linger
through Saturday night, but the main hazard will be the
lingering rough seas, especially across the southern coastal
waters.

Outlook /Sunday through Wednesday/...

Sunday: Moderate risk for Small Craft Advisory winds with gusts
up to 25 kt. Seas up to 5 ft. Chance of rain. 

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

Monday: Winds less than 25 kt. Seas locally approaching 5 ft. 

Monday Night through Wednesday: Winds less than 25 kt.
