.KEY MESSAGES...

  temperatures.

  Tuesday night, then around Friday into Saturday.

.DISCUSSION...
KEY MESSAGE 1...Rain leftover from Hurricane Isaias continues 
through tonight before moving offshore Monday followed by a 
quick warm up in temperatures.

The remnants of Hurricane Isaias continue to spread into 
eastern MA this afternoon as the center of the low strengthens 
and passes north of the 40/70 benchmark later tonight. Starting 
to see some heavier rain bands setting up across southern CT and
RI, slowly pushing north and east into MA, and see some 
rainfall rates of up to 0.5 inch per hour could be possible at 
times. Expecting moderate to heavy rain through midnight before 
lightening up in the early morning hours Monday, then finally 
pushing offshore late Monday morning or early afternoon. 
Widespread rainfall totals of 0.75"-1" is expected, as high as 
1.5" along the immediate south coast.

Skies will clear quickly behind the low thanks to some mid-
level dry air moving in from the north, allowing for a quick 
warm-up tomorrow afternoon. Monday's high temperatures rise into
the upper 60s, possibly the low 70s in the CT River Valley.

KEY MESSAGE 2...A few rounds of showers this week, first later 
Tuesday into Tuesday night, then around Friday into Saturday. 

Our region should then get clipped by a pair of low pressures, 
each taking a different track. The first should pass from the 
Great Lakes across northern New England Tuesday into Tuesday 
night. The risk for showers arrives across northern MA during 
the morning, then gradually moves south Tuesday night as the 
associated cold front approaches. Drying out Wednesday as this 
front finally moves farther offshore during the day. Expecting 
Wednesday to have above normal temperatures prior to this cold 
front moving by.

High pressure over eastern Canada should briefly take over our 
weather Wednesday night into Thursday night. Temperatures 
expected to trend below normal for Thursday.

The forecast for next Friday and Saturday still has timing 
uncertainties. That said, the latest guidance suite started to 
converge toward a common track and timing solution. The most 
likely period for rainfall still looks to be between noon Friday
and midnight Saturday. Some questions to how quickly it dries 
out on Saturday, but most of the guidance suite is more 
progressing than the GFS. Favored the consensus solution in this
regard.

Turning noticeably cooler this weekend, especially Saturday 
night into Sunday.
