.DISCUSSION...
KEY MESSAGE 1...Mostly dry with continued fall temperatures. An
early look at the holiday weekend favors dry weather, though 
late Sunday into Monday bears watching for rain.

Turning cooler tonight into Tuesday night, with below normal 
temperatures expected. Patchy frost will be possible tonight 
towards sheltered areas of the east slopes of the Berkshires. 
Winds will be too high to permit much frost. This should not be 
the case for Tuesday night. Thinking more widespread 
opportunities for frost across the normally colder locations of 
MA and northern CT. 

A quiet stretch of fall weather is expected Wednesday and beyond
as as high pressure remains the dominant feature. A vertically 
stacked low near Hudson Bay will send a few subtle shortwaves 
through New England Thursday and Friday. Limited moisture should
preclude significant rainfall, though a spot shower cannot be 
ruled out. Otherwise, dry weather prevails through the start of 
the holiday weekend. Forecast uncertainty increases late Sunday 
into Columbus Day and will depend largely on potential tropical 
development over the Bay of Campeche. The NHC currently gives 
AL92 an 80 percent chance of formation over the next 7 days. 
Some guidance brings remnant tropical moisture north into 
southern New England, while other solutions keep it suppressed 
to our south. Plenty of time to watch trends, with no reason to 
alter outdoor plans at this point. Temperatures remain fall-like
with highs mainly in the lower to middle 60s, except upper 60s 
to lower 70s Thursday. Overnight lows are mostly in the upper 
40s and 50s, though cooler upper 30s to middle 40s are possible 
Saturday night.
