.WHAT HAS CHANGED...
Snowfall amounts continued to increase slightly for late
Tuesday into Tuesday night, mainly across northern and northeast
MA.
&&
.KEY MESSAGES...
- Another cold night tonight, but with less wind.
- A quick moving clipper system will bring a period of
accumulating snow late Tue into Tue night.
- Upcoming period of dry, sunny days with seasonable
temperatures.
&&
.DISCUSSION...
Key Message 1...Another cold night tonight, but with less wind.
Ridge of high pressure advecting west to east across New
England tonight. This will support mainly clear conditions and
diminishing winds, combined with a deep snowpack. This will
result in lows in the single digits regionwide. The exception
will be along the immediate coast, Cape and islands, along with
the urban areas where mins will settle in the teens. Not as cold
as previous nights, nonetheless, colder than normal. Also, not
as much of a wind chill factor given the light winds. Minimum
temps were derived from the NBM and MOS datasets. We didn't want
to follow the coldest guidance, as some mid level cloudiness
from time to time overnight by preclude the coldest temp from
verifying. Nevertheless, a chilly/colder than normal night.
Key message 2...A quick moving clipper system will bring a
period of accumulating snow late Tue into Tue night.
Fairly potent northern stream shortwave moves into northern New
England Tue night...as the parent surface low passes to the
north. First band of warm advection light snow/flurries will
overspread the area 4PM-7PM west to east. Little if any
accumulation will occur with this first round. The
steadier/accumulating snowfall will occur roughly between 7 PM
and midnight. This will be more dynamical driven and will be
accompanied by a 2-4 hour window of moderate snow, supported by
10-15 ubar/s of lift in the DGZ. This strong forcing for ascent
induces a weak secondary low that tries to develop along the
boundary over or near SE MA.
Snow may end as period of rain along the south coast, in
response to modest low level WAA. Elsewhere, snow may end as a
brief period of freezing drizzle, as the DGZ dries out after
midnight. Given all the parameters above, expecting a coating up
to 2 inches of snowfall across CT/RI and southeast MA, possible
followed by a trace of ice before ending. For northern MA, 1-3"
is likely with localized amounts of 4+ in northeast MA,
followed by a trace of ice before ending. If 00z guidance trends
stronger/more qpf, the evening/night shift may issue winter
weather headlines. Stay tuned.
Key Message 3...Upcoming period of dry, sunny days with
seasonable temperatures.
Expecting a few days of dry weather after the clipper system
moves through Tuesday night/Wednesday morning. Winds return to
predominately northwesterly Wednesday, then high pressure begins
to build in over the Midwest/Mid-Atlantic regions Thursday.
Once the arctic airmass finally gets pushed offshore, we'll see
a return to more seasonable temperatures. High temperatures make
it back to the mid to upper 30s over southern New England from
Wednesday onward, though nighttime lows will still fall into the
teens and low 20s, with some spots in the interior in the
single digits. Thankfully though, wind chills will not be as low
as we have seen over the last few weeks.
