.WHAT HAS CHANGED...

Increased confidence in a period of light snow Tuesday afternoon 
into Wednesday. Slight chance that the snow continues into Wednesday 
across eastern Massachusetts but confidence is low at this point. 

&&

.KEY MESSAGES...

- Another very cold night tonight with wind chills down to 5 to
  20 degrees below zero. 

- Warming trend Tuesday ahead of a clipper system that brings a
  chance for light snow Tuesday night into Wednesday. Drier and
  milder conditions follow late next week. 

&&

.DISCUSSION...

Key Message 1...Another very cold night tonight with wind chills 
down to 5 to 20 degrees below zero. 

After a bitter cold morning we've "warmed" up into the teens this 
afternoon under full sun but gusty winds continue to make it feel 
like the single digits +/- OF. Winds, while decreasing, will be slow 
to come down as mesoanalysis continues to show a tight pressure 
gradient. We're sandwiched between the low to our east and a 
building high pressure over the Great Lakes. This high pressure 
center ever so slowly makes its way east as does a mid level ridge, 
but NW winds, while less breezy Sunday night/Monday, won't become 
truly calm until late Monday/Monday night. The airmass will continue 
to moderate over the next 24 hours (925 mb temps rise to around 
-8C by tonight) but this still leaves us with one more night of
 wind chill values necessitating a Cold Weather Advisory. This
 will be in effect in CT and Western/Central MA where minimum
 wind chills are expected to reach -10 to -20F for several
 hours. Elsewhere it will still be very cold, feeling more like
 the negative single digits to low teens. Sunny skies continue
 Monday with warmer temperatures as the coldest air shifts away
 from SNE; highs reach the upper 20s.

Key message 2...Warming trend Tuesday ahead of a clipper system
that brings a chance for light snow Tuesday night into 
Wednesday. Drier and milder conditions follow late next week. 


More seasonable temperatures arrive Tuesday as the flow becomes more 
southerly ahead of an approaching clipper. NBM shows highs in the 
lower 30s for much of the area as 850 mb temps climb to between -5 
and -7C.  

Increasing southerly LLJ on the order of 30-40kts advects higher 
PWAT values of around 0.5" over the CWA Tuesday afternoon as a warm 
front pushes ahead of an approaching clipper system . Weak mid-level 
frontogenesis provides enough forcing for areas of light snow and 
snow showers to break out around 18z Tuesday afternoon. Expecting 
areas of light snow to continue through Tuesday night and early 
Weds. Snow totals look light at the moment as the main low pressure 
will be fairly weak and well to the north of the CWA. Could even see 
some Ptype issues for the Cape and Islands with marginal boundary 
layer temps

System strengthens as it moves SE and offshore during the day on 
Wednesday. Recent guidance has begun to hint at the possibility of an 
inverted trough as the system pulls away Wednesday afternoon. This 
feature could bring additional light snow to eastern zones into 
Wednesday afternoon. These kinds of setups are admittedly low 
confidence even in the short term, so given that we are still a few 
days away, the specifics will need to be ironed out with future 
forecast updates. 

Following this system, high pressure builds in from the Great Lakes, 
drying the region out for the second half of the week. Ensemble 
guidance has temperatures moderating a bit and climbing back closer 
to climatological norms as well as a more climatologically normal 
airmass settles overhead.

High - greater than 60 percent.

Headlines: 

* Gale Warnings converted to Small Craft Advisories 

* Heavy Freezing Spray headlines continue through tonight.

N-NW gusts to 35-40 kt will gradually diminish below 30 kt this
afternoon. SCA gusts to 25-30 kt will continue tonight well into
Monday. Rough and hazardous seas today slowly subsiding tonight
into Monday. Areas of moderate to heavy freezing spray will 
continue through tonight as arctic air combines with rough seas.
Heavy freezing spray produces ice accretion rates up to 1 
inch/hr creating very dangerous conditions for vessels.

Chance of snow. 

Tuesday Night: Winds less than 25 kt. Chance of rain, chance of
snow. Local visibility 1 nm or less.
