.WHAT HAS CHANGED...

A Flood Watch has been issued for Connecticut. 

&&

.KEY MESSAGES...

- Cooler/seasonable temps return today with highs mainly in the
  upper 70s to the middle 80s. Mainly dry today outside a few 
  showers across western MA/CT and near the south coast. 

- Confidence growing in the potential for bands of heavy rainfall 
  & even the risk for localized flash flooding late tonight into Tue.
  Greatest risk for this right now is in northern CT...where a
  Flood Watch has been issued. 

- Summer warmth & humidity return for the latter half of the week. 
  A few showers and thunderstorms possible by Fri-Sat.

.DISCUSSION...

KEY MESSAGE 1...Cooler/seasonable temps return today with highs 
mainly in the  upper 70s to the middle 80s. Mainly dry today outside 
a few showers across western MA/CT and near the south coast. 

The upper level ridge has finally broken down across the 
region...which will bring a return to cooler/seasonable temperatures 
today. We do expect a scattered to broken deck of mid-level 
cloudiness across the region as a weak surface boundary slowly lifts 
north across the region. Dry weather will dominate today...except 
for a few showers across western MA/CT and near the south coast 
given their proximity to deeper moisture and forcing. 

KEY MESSAGE 2...Confidence growing in the potential for bands of 
heavy rainfall & even the risk for localized flash flooding late 
tonight into Tue. Greatest risk for this right now is in northern 
CT...where a Flood Watch has been issued. 

Confidence is growing in the potential for bands of heavy rainfall 
and even the risk for localized flash flooding late tonight into 
Tue. This is a rather complex forecast in trying to determine the 
location and greatest risk for torrential rainfall/localized flash 
flooding which we will discuss more below.

Weak high pressure over eastern Canada will help to focus a shallow 
boundary at the surface. Just above that a modest ESE low level of 25 
to 35 knots at 925 mb will impinge on this surface boundary. This 
will combined with Pwats of 1.5 to 2+ inches and set the stage for 
bands of heavy rainfall late tonight into Tue with some embedded 
thunder possible. We are essentially combining synoptic scale 
forcing with summertime moisture and instability...which is a good 
setup of for bands of torrential rainfall and potential for 
localized flash flooding. The models do quite a good job these days 
in indicating the potential for torrential rainfall/localized flash 
flooding. However...they often struggle to depict the location given 
various mesoscale parameters in play. Currently, the models seem to 
be favoring our southwest zones where the best moisture and Pwat 
plume are located. 

Given the above...we have gone ahead and issued a Flood Watch for 
our CT zones. This is for a widespread 1-3 inches of rainfall...But 
the potential for localized narrow bands of 4-6 inches of rain 
inside 6 hours. If this were to occur...the potential would exist 
for both urban and small stream flash flooding late tonight into 
Tue. Later shifts may need to expand the Flood Watch further north 
and east...But we felt this was a good starting point for now. It is 
also possible that the heavy rain/flood threat remains to our 
southwest...But either way felt a Flood Watch for CT was reasonable 
to just highlight the potential. 

KEY MESSAGE 3...Summer warmth & humidity return for the latter half 
of the week. 

Drier weather works into the region by Wed as the shortwave trough 
departs. Westerly flow will develop by late in the week bringing 
typical summertime warmth and humidity back into the region...But 
fortunately not the extreme heat we have dealt with the last few 
days. There will also be the risk for a few showers and 
thunderstorms by Fri-Sat as the next shortwave works into the 
region.

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...

Forecaster Confidence Levels...

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

06z TAF Update...

Today through Monday...Moderate confidence.

Mainly VFR today but some lower MVFR conditions possible at times 
today in a few showers across western MA/CT and near the south 
coast. MVFR conditions become more widespread across western MA/CT 
later tonight and Mon along with periods of showers with locally 
heavy rainfall. 

Light ESE winds today and tonight becoming E at 6 to 13 knots on 
Mon. 

KBOS Terminal...High confidence in TAF.

KBDL Terminal...High confidence in TAF.

Outlook /Monday Night through Thursday/...

Monday Night: Mainly MVFR, with areas IFR possible. Breezy.
SHRA, slight chance TSRA, patchy BR.

Tuesday: MVFR/IFR conditions possible. Windy with local gusts
up to 30 kt. Chance SHRA, slight chance TSRA, patchy BR.

Tuesday Night: Mainly VFR, with areas MVFR possible. Breezy.
Chance SHRA.

Wednesday through Wednesday Night: VFR. 

Thursday: VFR. Breezy.

.MARINE...

Forecaster Confidence Levels...

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

Today and tonight...High confidence.

High pressure over eastern Canada combined with a wave of low 
pressure passing to our south will result in ESE winds today and 
tonight...But the winds/seas should remain below small craft 
advisory thresholds.

Monday...Moderate confidence.

Wave of low pressure passing to our south should result in E wind 
gusts increasing to around 25+ knots across our southern waters. 
Later shifts will likely need to issue small craft advisories for 
our southern waters and we may need to expand them further north 
Monday night. 

Outlook /Monday Night through Thursday/...

Monday Night: Moderate risk for Small Craft Advisory winds with
gusts up to 30 kt. Local rough seas. Rain showers, slight
chance of thunderstorms, patchy fog. 

Tuesday: Moderate risk for Small Craft Advisory winds with
local gusts up to 30 kt. Rough seas up to 10 ft. Rain showers
likely, slight chance of thunderstorms, patchy fog. 

Tuesday Night: Winds less than 25 kt. Rough seas up to 10 ft.
Chance of rain showers, slight chance of thunderstorms. 

Wednesday: Winds less than 25 kt. Rough seas up to 9 ft. Slight
chance of rain showers. 

Wednesday Night through Thursday: Winds less than 25 kt. Seas
up to 5 ft.
