.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.

Dissipating showers moving east across southern New England this
afternoon could result in a couple of hours with stronger gusts
than what we have seen so far today. Peak wind gusts up to 
35-40 mph are possible before sunset, but most will only be
25-30 mph. 

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 through much of the 
period 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.
