.SYNOPSIS...
High pressure then governs our weather through at least early 
next week, maintaining dry weather and above average 
temperatures for the foreseeable future. 

&&

.NEAR TERM /THROUGH TONIGHT/...
High pressure in control of our weather tonight. Expecting winds
and clouds to diminish with sunset, setting up near ideal
radiational cooling conditions. Favored the lower temperature
guidance tonight. 

Some question about the possibility for fog overnight. Most
likely area would be across portions of the lower CT River 
valley. At this time, kept fog out of the forecast with dew
points expected to be in the upper 30s to lower 40s. That may be
a little bit too dry for fog to develop. This aspect of the
forecast will need to be monitored this evening.

&&

.SHORT TERM /WEDNESDAY/...
High pressure should be more overhead Wednesday, then moving
offshore for Wednesday Night. Weaker pressure gradient should
permit more seabreezes during the day, then another night of
rather light S-SW or near calm winds. Slightly higher dew points
expected later in the day into Wednesday night. Near to slightly
below normal temperatures expected.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH TUESDAY/...
Key Point:

* Dry weather and above average temperatures into early next 
week

About as quiet as the weather gets around here and this pattern  
looks to hold through at least early next week if not a bit
longer. Ridging aloft and high pressure at the surface will
remain anchored over New England maintaining mostly sunny, warm 
days and clear, cool nights through the period.

There is a weak shortwave that passes by to our north sometime
Friday but at this point it appears to be moisture starved and
should only produce some cloudiness. NBM 24 hour probabilities
for 0.01" or more of precipitation have decreased and are well 
below 10 percent, so we will maintain a dry forecast.

Tropics are becoming a bit more active this week but there are
no direct threats right now. Certainly something to monitor over 
the next few weeks as we are in the heart of the tropical season
in the Atlantic.

&&

development on both coasts, soonest at KBOS around 15z and
