.WHAT HAS CHANGED...
No significant changes were made to the forecast through
Tuesday.

.KEY MESSAGES...

- Lingering snow showers end later this afternoon giving way to
  very cold temperatures tonight through Tuesday morning.

- A wintry mix of precipitation is possible Tuesday into 
  Tuesday night. 

- Remaining unsettled beyond Wednesday with temperatures 
  trending above normal.

.DISCUSSION...
KEY MESSAGE 1...Lingering snow showers end later this afternoon
giving way to very cold temperatures tonight through Tuesday
morning.

Line of light to moderate snow showers quickly exits the coast
later this afternoon, weakening as it does so. Should see skies 
quickly clear with increasing northwest winds and a sharp drop
in temperatures this evening. The Arctic front ushers in another 
round of very cold temperatures starting tonight and lasting
into Tuesday morning. 850 mb temps bottom out at -16C Monday
morning, with the 510 thickness line nearly reaching southern 
New England. This will result in low temperatures Monday morning
in the low single digits, possibly below zero in NW MA. With a
little leftover wind from the arctic front overnight, the wind
chill index will be below zero Monday morning, possibly
approaching -10 across the interior.

Despite the higher March sun angle, high temperatures will stay
below freezing on Monday with a wind chill index in the lower 
20s. 850mb temperatures begin to rise overnight Monday. However, 
strong radiational cooling under calm winds and clear skies will
allow low temperatures to bottom out in the low teens to high 
single digits Tuesday morning. 

KEY MESSAGE 2...A wintry mix of precipitation is possible
Tuesday into Tuesday night. 

Still expecting a wintry mix to develop Tuesday into Tuesday
night. Temperatures should initially remain low enough where
some light snowfall is possible across the higher terrain of 
CT and MA. Not expecting this will last long as temperatures
continue to rise. Expecting plain rainfall across most of
southern New England by Tuesday evening. Still thinking the cold 
front associated with the low pressure passing by our region
should be off the coast by Wednesday morning. Thus, decreasing
precipitation chances from NW to SE late Tuesday night. Should 
be dry across all of southern New England by mid morning 
Wednesday.

Thinking light snowfall accumulations of generally less than 1
inch. Kept the possibility of freezing rain out of the forecast 
at this time, largely because it would be brief and the timing
remains uncertain. Will get a better handle on this as we get
more into the range of the high resolution guidance. A more
substantial period of freezing rain would only cut into snowfall 
accumulations even more. However, winter weather headlines may 
be needed for the icing potential.

KEY MESSAGE 3...Remaining unsettled beyond Wednesday with 
temperatures trending above normal. 

The active weather pattern continues through the end of this
upcoming work week as the zonal jet stream and stalled frontal
boundary send several weak waves near or through southern New
England. Temperatures starting Wednesday are expected to rise
well above normal, with highs approaching the 50s and overnight 
lows even staying near or above freezing. This will help keep 
any precipitation that falls during this time as rain.

Still thinking our region gets caught between a pair of fronts 
Thursday into Friday, making this a more specific time with a
greater risk for rainfall. Otherwise, it appears that we'll have 
at least a chance of off-and-on precipitation through next 
weekend.
