.WHAT HAS CHANGED...

A Gale Watch has been issued for all of the coastal and outer
waters for Saturday. Gusty northerly winds are possible with the
passage of a strong low pressure system.

&&

.KEY MESSAGES...

- Cooler today with scattered showers developing in the afternoon, 
  especially across eastern with a low risk of an isolated t-storm. 

- Unsettled conditions Friday through early next week with
  periods of showers. Gusty northerly winds possible Saturday.

&&

.DISCUSSION...

KEY MESSAGE 1...Cooler today with scattered showers developing in 
the afternoon, especially across eastern MA with a low risk of
an isolated t-storm.

Cooler temperatures are expected today within the post-frontal 
airmass. 925mb temperatures range 11-13C, supporting highs in the 
low to mid 70s for most while onshore flow will hold highs in the 
upper 60s along the east MA coast. A shortwave trough drops 
southward across the region accompanied by a slight uptick in 
moisture. Weak ascent with the wave should be sufficient enough to 
trigger light scattered showers after late morning through the 
evening. Surface flow fields show indications of a coastal front off 
the eastern MA coast extending southward  with E/NE flow offshore 
and N/NNW winds not far inland. This should act to enhance moisture 
convergence along the coastal and near-coastal areas thus favoring 
those areas for the greater risk for scattered showers. Enough
instability may be present for the low risk for an isolated
t-storm or two...But not expecting any severe weather. 


KEY MESSAGE 2...Unsettled conditions Friday through early next week 
with periods of showers. Gusty northerly winds possible Saturday.

There is a good consensus among ensemble guidance for a blocky upper 
level pattern to set up over the northeast featuring upper troughing 
Friday through early next week. Several shortwaves moves through the 
broad cyclonic flow aloft bringing periodic chances for 
showers/rain.

The first wave features a closed upper low that drops south across 
southern New England late Friday into Saturday. There is still some 
spread amongst guidance on the exact timing of the wave and 
arrival of showers. Some guidance (GFS/AIGFS) indicates showers 
arriving as early as late Friday afternoon, while others lean 
later (Fri night). Showers continue through Saturday, with 
showers gradually diminishing in the afternoon/evening. With 
limited moisture, rain amounts aren't expected to be heavy with 
ensembles generally showing a more likely range of 0.20" to 
0.80" with the higher amounts favored in northeast MA. 
Temperatures trend below normal Saturday in the upper 50s to low
60s. The pressure gradient tightens as a surface low tracks 
across the region which will promote a period of gusty N-NE 
winds Saturday. The expected gusts will depend on the track of 
the low, but if the low tracks nearby gusts 30-40 mph are 
possible, isolated 45 mph can't be ruled out. The ECMWF ensemble
leans toward widespread gusty winds with moderate to high probs
for gusts greater than 40 mph. However, the GEFS shows weaker 
winds overall and confines low-moderate probabilities for 40 
mph+ to the Cape and waters. Something we will keep monitoring. 

Sunday trends drier and more seasonable with a 
mix of sun and clouds. 

A few more waves move through the flow beyond Sunday into early next 
week. There is still spread in the details of the waves such as the 
timing, but they may support periodic chances for showers. There is 
a better consensus for a round of showers sometime Monday and 
another Tuesday. 850mb temperatures anomalies lean below normal 
early next week likely yielding temperatures in the 60s and low 70s 
through Wednesday. There are signs of the blocky pattern breaking 
down later next week which should help warm temperatures back
up.

.AVIATION /12Z THURSDAY THROUGH MONDAY/...

Forecaster Confidence Levels...

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

12z TAF Update...

Today...High Confidence. 

VFR outside brief scattered showers developing this afternoon
especially across eastern MA. Low risk for an isolated t-storm
or two...But certainly northing widespread. Winds will become N-NW
winds at 10-15 kts with gusts of 20+ kts for the interior 
terminals and E-NE 7-13 kts near the eastern MA coast. 

Tonight...High confidence. 

VFR. Light N-NW wind. 

KBOS...High confidence in TAF. The main risk for brief scattered
showers in the vicinity of terminal will be after 18z through 
about 00z/01z. There is a low risk for a brief rumble of 
thunder as well.

KBDL...High confidence in TAF. 

Outlook /Friday through Monday/...

Friday: VFR. Breezy. Chance SHRA.

Friday Night: Mainly VFR, with local MVFR possible. Windy with
local gusts up to 35 kt. Chance SHRA, patchy BR.

Saturday: Mainly VFR, with local MVFR possible. Windy with
gusts up to 35 kt. Chance SHRA.

Saturday Night: VFR. Windy with local gusts up to 30 kt. 

Sunday: VFR. 

Sunday Night: VFR. Slight chance SHRA.

Monday: VFR. Chance SHRA, slight chance TSRA.

.MARINE...
Forecaster Confidence Levels...

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

Today and Tonight...

Winds and seas below SCA thresholds. N winds tonight. N-NE winds
5-15 kts today becoming N-NW tonight. Scattered showers 
developing Thu afternoon. Low chance of an isolated storm. 

We issued a Gale Watch for all the waters for Saturday due to
the potential for a stronger low pressure to track across the
region bringing gusty N-NE winds. Confidence is moderate as the
Gales will depend on the track of the low. 

Outlook /Friday through Monday/...

Friday: Winds less than 25 kt. Chance of rain showers. 

Friday Night: Low risk for Small Craft Advisory winds with
gusts up to 30 kt. Areas of seas approaching 5 ft. Rain
showers, slight chance of thunderstorms, patchy fog. 

Saturday: Strong winds with gusts up to 40 kt. Areas of rough
seas. Chance of rain showers. 

Saturday Night: Low risk for Small Craft Advisory winds with
areas of gusts up to 30 kt. Rough seas up to 11 ft. 

Sunday: Winds less than 25 kt. Local rough seas. 

Sunday Night: Winds less than 25 kt. Areas of seas approaching
5 ft. Slight chance of rain showers. 

Monday: Winds less than 25 kt. Seas locally approaching 5 ft.
Chance of rain showers, slight chance of thunderstorms.
