.SYNOPSIS...
A warm front will lift into New England tonight bringing a
period of snow to a wintry mix that will change to rain
Thursday. High pressure builds in Friday for fair weather. Low
pressure tracking into the St Lawrence Valley will bring another
round of wintry precipitation changing to rain late Saturday
into Sunday. Additional waves of low pressure will track along
a frontal boundary that will be near southern New England early
next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
Tonight, a low moves eastward, bringing some precipitation into
the region. An isothermic environment tonight will allow for
most precipitation to start as snow. Overnight, southerly winds
at low levels will break the isothermic layer allowing for a
gradual changeover to sleet and freezing rain overnight.

&&

.SHORT TERM /THURSDAY/...
Tomorrow morning, interior locations are the most likely to see
mixed precipitation into the morning commute, but mixed
precipitation will transition to rain from south to north. Once
transitioned to rain, temperatures will likely rise, as warm
air works its way down to the surface tomorrow afternoon. High
temperatures are likely to be in the upper 50s and 60s in the
Connecticut River Valley and southern New Hampshire, with
mid-40s in Maine and elsewhere.

&&

.LONG TERM /THURSDAY NIGHT THROUGH WEDNESDAY/...
Overview: High pressure will build in Friday for fair weather. A
period of active weather follows as wave of low pressure track along
a frontal zone that slowly shifts south of the area early next week.
The first wave will bring widespread wintry precipitation late
Saturday into Sunday. Thermal profiles with this system will support
snow/wintry mix across the interior early Saturday night with a
transition to rain from SW to NE Sunday morning. There may be a lull
in precipitation Sunday afternoon before the next wave of low
pressure tracks across southern New England Sunday night. Chances
for precipitation drop off Monday while global models suggest
additional systems will be possible towards the middle of next week
with a trough approaching the Northeast.

Impacts: Snow to a wintry mix could bring slick travel across
northern areas late Saturday through Saturday night.

Details: Drier air will work into the area Thursday night into
Friday on NW flow. A NW gradient will remain over area Friday as
high pressure builds in from west with wind gusts approaching 25
mph. Skies will turn mostly sunny by Friday afternoon with highs
ranging from the mid 40s north to mid 60s across southern NH. High
pressure will crest over the area Friday night allowing for lows to
drop into the low 20s to low 30s from north to south.

A wave of low pressure will track from the Ohio Valley towards the
St Lawrence Valley late Saturday into Sunday with precipitation
likely overspreading the area by Saturday afternoon. A dry airmass
in place will allow for some wet bulbing leading precipitation
starting as snow across the north and a mix of rain and snow
south of the mountains. Warm air advection will continue through
Saturday night with precipitation changing to a wintry mix
across the north and rain across the south by Sunday morning.
Temperatures will eventually rise above freezing across all
areas after day break Sunday with rain becoming the dominant
precipitation type. Precipitation will taper off Sunday
afternoon before the next wave of low pressure approaches Sunday
night.

The next wave of low pressure will bring chances for rain south
of the mountains and a mix of rain and snow across the north
Sunday night into Monday. Colder air attempts to work into the
region Monday night that may allow for snow showers south of the
mountains.
