.SYNOPSIS...
Temperatures moderate today into Saturday but remaining below 
normal. Other than scattered snow showers on the Cape and Islands 
today and passing snow showers associated with a Clipper low 
pressure area Sunday, mainly dry weather is expected into early next 
week. Temperatures are expected to rebound to near seasonable 
normals for Sunday into early next week.

&&

.NEAR TERM /UNTIL 6 PM THIS EVENING/...
Mid level shortwave from the west will be moving into SNE 18-00z. A 
weak low pres well to the south will bring a plume of deeper 
moisture which is likely to remain just offshore. However, the NW 
extent of the moisture may get close enough to bring some snow 
showers to the Cape/Islands today. Soundings show moist layer up to 
about 850 mb but pretty dry above that in the 800-700 mb layer. Not 
expecting much accums, perhaps a coating to 1/2" in a few spots. 
Otherwise, area of mid-high level moisture moving into SNE around 09-
12z will lifting to the north by 15z leading to clouds giving way to 
partly to mostly sunny skies from west to east in the afternoon. 925 
mb temps are moderating today which will bring milder temps but 
still several degrees below normal with highs mostly upper 20s to 
lower 30s, colder higher terrain.

&&

.SHORT TERM /6 PM THIS EVENING THROUGH 6 PM FRIDAY/...
Tonight...

Mid level shortwave moves to the east this evening and will be 
followed by low level NW flow and subsidence. Mainly clear skies are 
expected with perhaps some strato-cu developing over the Berkshires. 
Winds will be light so good radiational cooling will result in low 
temps dropping into the single numbers and teens. 

Friday...

SNE will be in between shortwaves to the north and SW with dry low 
level NW flow persisting. Mostly sunny skies are expected with 
similar temps to today as there is little change in low level temps. 
Highs will be mostly upper 20s to lower 30s with a modest NW breeze. 

&&

.LONG TERM /FRIDAY NIGHT THROUGH WEDNESDAY/...
Key Messages: 

* Benign weather and mainly dry conditions for much of the region 
  for the extended forecast. A weak clipper system, passing to our 
  north on Sunday could lead to a couple of light snow showers for 
  far western southern New England. 

* Seasonably cold on Saturday, followed by near normal temperatures 
  Sunday through at least Tuesday. 

Benign weather continues for much of the extended forecast period 
with a 1030mb +/-5mb high pressure anchored across the eastern third 
of the CONUS. Will have a couple of very weak disturbances traverse 
the region, but not expecting any notable impacts. On Sunday, a weak 
area of low pressure associated with a subtle mid-level trough and 
shortwave cross northern New England. There is very little moisture 
associated with this, PWATs are less than 0.2", at best there would 
be potential for snow showers in western MA and northwest CT. Did 
keep 'slight chance' POPs in those locations. As prior discussions 
mentioned, there is no significant systems on the horizon. Guidance 
has high pressure to our south through the middle part of next week, 
but a couple of moisture starved clippers dive out of Canada and 
cross northern New England between Monday and Wednesday. The 
ensembles paint a pretty dry picture, with limited opportunities for 
QPF. 

Seasonably cold temperatures for Saturday, highs between upper 20s 
and low 30s. That is followed by a relative warm-up between Sunday 
and Tuesday, highs reach the middle to upper 30s and overnight lows 
in the upper teens and low 20s. Heading towards the middle part of 
next week brings the chance for another surge of Arctic air and 
below normal temperatures.
