.DISCUSSION...
KEY MESSAGE 1...Dry and cool conditions continue through the 
weekend.

Cold start to the day today as radiational cooling cools the column 
resulting in temperatures in the mid to low 20s inland and low to 
mid 30s near the coast.  Should see a quick rebound by this 
afternoon with highs warming into the upper 50s to low 60s across 
the interior. By tonight, overnight lows away from the coast likely 
drop into the mid to low 30s. The relatively warmer low temps are 
the result of slightly higher dew point temperatures that will range 
from the mid 30s to the low 40s as a weak SWrly return flow ushers 
in moisture. Warming trend continues into the early week as 925mb 
temperatures warm significantly over the next 24 to 36 hours, up 
from +3C this morning to +10C by this evening. This will jump 
start a warming trend for the week. 

KEY MESSAGE 2...Above normal temperatures Tuesday through Thursday, 
with continued dry weather.

Surface high pressure continues to remain in control, essentially 
thematic of the last roughly 10 days. However aloft, the 500 mb 
pattern becomes increasingly amplified as a slow moving but powerful 
frontal system over the nation's midsection induces a plume of 
enhanced southwest flow aloft. This in turn will lead to an 
amplifying 500 mb ridge and bring an anomalously warm low-level 
airmass (e.g. 925 mb temps around +12 to +14C) over Southern New 
England as we move into the Wednesday through Thursday timeframe. 

Besides a continued stretch of dry weather/no rainfall - the region 
hasn't seen an appreciable wetting rain since October 16th - the 
main story for Tuesday through Thursday is above normal 
temperatures. All this despite sunset times around 430 pm as we move 
toward solar winter. The combo of continued southerly flow, the warm 
low-level airmass and the drying soil should help boost high 
temperatures to levels around 10 degrees above normal, especially as 
we move into Wednesday and Thursday when the 925-850 mb thermal 
ridge builds in. Expect highs to reach well into the 60s with some 
low 70s as well (climo is around the mid 50s), and lows should also 
run significantly above normal as well in the low to mid 50s (climo 
in the mid 30s to lower 40s).

KEY MESSAGE 3...Turning unsettled Friday into at least a part of 
next weekend.

Ensembles point to the amplified mid-level ridge from Wed/Thurs 
shifting eastward into the western Atlantic by Friday, as the slow-
moving frontal system over the OH/MS Valleys begins to affect 
Southern New England. There still are quite a few uncertainties and 
unresolved details typical of a day-6 timeframe specific to this 
system, including rain amounts, its timing and if the system can 
draw on a plume of subtropical moisture to enhance rain rates. 
Ensemble 24-hr QPF probabilities from Friday through Saturday show 
moderate (40-60%) probabilities 0.5" or more of rain with low to 
moderate (up to 30%) probabilities of an inch or more of rain. While 
temps should still run above normal and also run a touch humid (by 
early Nov standards), this looks to be the next really good chance 
at much-needed wetting rainfall.
