- Scattered showers exiting by late afternoon. Becoming windy
  into this evening, then clearing and cold with diminishing

- Dry conditions with less wind Wednesday and Wednesday night.
  Below normal temps continue.

- Warming trend to temperatures Thursday and Friday. Still very

.DISCUSSION...
KEY MESSAGE 1...Scattered showers exiting by late afternoon.
Becoming windy into this evening, then clearing and cold with 
diminishing wind overnight.

Mid level trough passage and cold pool move through this 
afternoon. Scattered showers associated with this trough are 
moving through SNE this afternoon and can't rule out some
graupel given the cold air aloft and steep lapse rates. As the
cold front moves through this afternoon winds will shift to NW 
with 25-35 mph gusts into early evening. A few 40 mph gusts are
possible over higher terrain.  

The trough exits tonight followed by subsidence and high pres 
building in from the west. Expect clearing skies with 
diminishing wind overnight as the gradient slackens. It will be 
rather cold for this time of year with lows dropping into the 
20s and some teens in the colder spots in western MA.

KEY MESSAGE 2...Dry conditions with less wind Wednesday and 
Wednesday night. Below normal temps continue.

Strong high pres builds across New Eng Wed before shifting to the 
east Wed night. Despite abundant sunshine Wed, shallow mixing and 
light winds will result in a cool day with highs in the 40s to 
perhaps low 50s in the lower CT valley. Developing sea-breezes 
will likely hold temps near 40F along the eastern MA coast and
Cape/Islands.

Mainly clear skies and light winds Wed night as high pres slowly 
drifts offshore, but ridging hangs back across New Eng. Another
cold night with lows in the 20s. 

KEY MESSAGE 3...Warming trend to temperatures Thursday and 
Friday. Still very dry Thursday which could lead to fire weather
concerns as southerly winds increase.

Steady warming trend continues Thursday and Friday with a ridge of 
high pressure anchored to our southern coastline. Mostly clear to 
partly sunny conditions should dominate both days, with south to 
southwest winds around 10 mph, up to 15 mph in western portions of 
Southern New England. Dewpoints are still not likely to have 
recovered enough by Thursday, which will bring relative humidities 
given favorable mixing down into the 20-25 percent range; thus, 
possible fire weather concerns on Thursday, although the winds/gusts 
are not particularly strong. Warmer day on Friday will be met with 
more moisture too, with highs Friday into the 60s. All in all 
though, both days are rather pleasant.  

KEY MESSAGE 4...Dry weather generally prevails late this week 
into early next week. Cooler temperatures for the weekend, but 
growing confidence on a spell of above normal temperatures for 
early next week.

Latest guidance now indicates a moisture-starved cold frontal 
passage now about 6-12 hours sooner, instead moving through Saturday 
morning. Other than some cloud cover, chances for rain with this 
frontal passage look scant. Passage of the cold front will bring 
arrival of cooler temperatures later Saturday with a period of 
onshore flow/marine-influenced air for Sunday. 

Only looks to be a brief cooldown though, as we enter into a stretch 
of very mild weather for at least Monday and Tuesday. 925 mb temps 
warm into the upper teens to around +20C, which would support highs 
in the mid 70s factoring in southwesterly flow downsloping.
