.DISCUSSION...
KEY MESSAGE 1...Overcast conditions the rest of today give way 
to mostly sunny and breezy conditions on Sunday. Temperatures 
slightly cooler than normal through this weekend.

Skies have trended toward mostly cloudy/overcast conditions with 
modest NW breezes, in response to a rather potent shortwave 
disturbance aloft seen on satellite imagery circulating near 
Montreal. While currently dry, there are a number of light but non-
trace 1-hourly QPF amts being reported by METARs in northern New 
England; while dry weather generally prevails, a sprinkle or light 
shower are possible as this shortwave disturbance moves southward 
through Southern New England late this afternoon into early tonight. 
Any additional diurnal warming looks minimal today with the cloud 
cover and northerly breezes, in the upper 30s to the mid 40s! Early 
cloud cover and northwest breezes will keep temps from really 
dropping quickly, but decreasing clouds after midnight should bring 
lows down to the upper 20s to mid/upper 30s. 

We do expect there to be more sunshine on Sunday compared to today, 
although low-level thermal profiles still are rather cool. This 
should support better mixing with northwest gusts in the 20 to 25 
mph range, which will add a bit of a chill despite sunny conditions. 
Expect highs in the mid to upper 40s, but it will feel closer to the 
mid-30s if you're doing any hikes in the higher terrain. 

KEY MESSAGE 2...Prolonged period of dry and quiet weather, with
moderating temperatures next week, yielding mild afternoons and
cool nights.

All guidance, including AI models, have large amplitude central US 
ridge this weekend slowly advecting to the East Coast next week. 
Hence, a prolong stretch of dry weather for SNE. Regarding 
temperatures, chilly to begin the week Monday, but height rises 
aloft will support warming temps and with surface high setting up 
across the OH Valley to the Mid Atlantic region, this will place SNE 
in a warming WNW flow. Given this setup, wouldn't be surprised if 
forecast highs overachieve into the mid 60s in the Wed-Fri 
timeframe! Thus, the temp theme next week will be cool highs in the 
upper 40s and lower 50s Monday, jumping into the 60s mid to late 
next week. These temps are about 10-15 degs warmer than normal for 
mid Nov.

Dew pts in the 30s along with light winds, will result in a large 
diurnal temp spread, with seasonably cool nights, as lows dip into 
the 30s for most locations. The mild daytime temps likely linger 
into Fri, before a dry cold front moves across the region Fri/Sat. 
Ensembles suggest not much of a post frontal airmass change, with 
highs only cooling back to seasonal levels, with highs in the 50s. 
Hence, mild days and cool nights will be the theme for much of next 
week.
