.WHAT HAS CHANGED...
No meaningful changes to the forecast as quiet weather takes hold of 
the region. Refinements to marine headlines, downgrading Gale 
Warnings to Small Craft Advisories as Post-Tropical Cyclone 
Josephine moves east and south of Nova Scotia and New Brunswick 
today into tomorrow. 

&&

.KEY MESSAGES...

- Dry weather continues through the weekend and much of next
  week. Cool today, with moderating afternoon temperatures this
  weekend, though chilly mornings will bring widespread frost to
  much of the area away from the immediate coast.

.DISCUSSION...
KEY MESSAGE 1...Dry weather continues through the weekend and much 
of next week. Cool today, with afternoon temperatures gradually 
moderating this weekend, though chilly mornings will bring 
widespread frost to much of the area away from the immediate coast.

As anticipated, Subtropical Storm Josephine has undergone 
extratropical transition, now Post-Tropical Cyclone Josephine per 
the National Hurricane Center. This system is moving east and will 
pass to the south of Nova Scotia and New Brunswick Friday into 
Saturday. With the center of the system moving further east into the 
North Atlantic Ocean, expansive high pressure builds across the 
Northeast. Thus, any lingering gusts of 20 to 30 mph will be 
confined to the easternmost waters and adjacent coastal areas, 
particularly from Cape Ann to Cape Cod and the Islands. Winds 
diminish late this morning into the afternoon, while areas farther 
inland will be treated to a pleasant day with light northerly winds 
of 5 to 10 mph. Full sunshine today with highs ranging from the 
lower to middle 50s. 

Looking ahead, there really isn't any sensible weather to discuss as 
the aforementioned high pressure system remains the dominant weather 
feature for the foreseeable future. However, a weak cold front 
starved of moisture approaches from the north-northwest on Tuesday. 
Strong high pressure and dry air will likely cause this front to dry 
out before reaching southern New England, perhaps adding some cloud 
cover at most. In fact, global ensembles paint a rather parched 
picture for southern New England, with probabilities of measurable 
precipitation (0.01 inches or greater) generally less than 10 
percent from Friday through Wednesday of next week.

In terms of temperatures, expect moderating afternoon temperatures 
this weekend, returning to the upper 50s/lower 60s on Saturday and 
low to middle 60s on Sunday and Monday. Saturday and Sunday mornings 
will be quite cold, with lows dropping into the 20s to lower 30s and 
widespread frost likely away from the immediate coast. Be sure to 
protect those mums and Halloween pumpkins! Opted to trend overnight 
lows below NBM guidance, which tends to run too warm during 
efficient radiational cooling setups, especially with clear skies, 
calm winds, and strong 1030+ mb surface high pressure overhead. 
Tuesday into the upcoming week seasonable temperatures day and night 
are expected. 

&&

.AVIATION /06Z FRIDAY THROUGH TUESDAY/...
Forecaster Confidence Levels...

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

06Z TAF Update:

Today through Saturday...High confidence.

VFR conditions prevail through the period. N to NNE winds 10 to 15 
kt, gusting 20 to 30 kt today at eastern terminals. Farther inland, 
N winds around 10 kt. Gusty winds gradually diminish between 00Z and 
04Z tonight, with winds generally 5 to 10 kt overnight. Some 
interior terminals may become calm as high pressure settles in. By 
Saturday, light W to WNW winds of 4 to 8 kt are expected.

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Saturday through Tuesday/...

Saturday: VFR. 

Saturday Night: VFR. Patchy frost.

Sunday: VFR. 

Sunday Night: VFR. Patchy frost.

Monday: VFR. 

Monday Night through Tuesday: VFR. Breezy. 

&&

.MARINE...
Forecaster Confidence Levels...

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

Through Saturday...High confidence.

Improving conditions are anticipated today and will continue into 
the upcoming weekend. Josephine, now a post-tropical cyclone, is 
moving east of the waters and will pass to the south of Nova Scotia 
and New Brunswick today into Saturday. As the storm exits east, 
strong surface high pressure moves in from the west, easing the 
pressure gradient and allowing the winds to relax. Current Gale 
Warnings across the eastern ocean waters will be converted to Small 
Craft Advisories early this morning, mainly for lingering northerly 
wind gusts of 20 to 30 kt and rough seas. Existing Small Craft 
Advisories south of Block Island will remain in effect through 11 PM 
this evening due to seas around 4 to 6 ft. By Saturday, with high 
pressure overhead, winds will be light and generally from the 
northwest, with gusts at most 8 to 12 kt. High pressure remains in 
control, leading to favorable marine conditions for the next several 
days. 

Outlook /Saturday through Tuesday/...

Saturday: Winds less than 25 kt. Areas of rough seas. 

Saturday Night: Winds less than 25 kt. Local rough seas. 

Sunday: Winds less than 25 kt. Areas of seas approaching 5 ft. 

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

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

RI...None.
MARINE...Small Craft Advisory until 8 AM EDT this morning for ANZ230-
     233>235-237.
