AREA FORECAST DISCUSSION
National Weather Service Burlington VT
327 AM EST Sun Dec 30 2018

.SYNOPSIS...
High pressure over the region today will bring drier weather to
the North Country along with colder temperatures. The dry 
weather continues tonight into the first half of Monday before a
warm front lifts up into the region New Years Eve night. This 
feature will bring a wintry mix of precipitation to the area, 
which could result in difficult travel.

&&

.NEAR TERM /THROUGH MONDAY/...
As of 244 AM EST Sunday...High pressure over the area today 
should keep much of the area dry with highs in the 20s to around
30. A weak upper level disturbance could bring a few snow 
showers to parts of northern New York late this afternoon and 
evening, but this precipitation should be fairly spotty and 
light. Favorable southwesterly flow off Lake Ontario will 
enhance the snow showers a bit, though think only a chance for 
some light snow showers in the Southern Saint Lawrence valley. A
bit more cloud cover will exist over the area tonight and thus 
lows will generally be in the mid teens to lower 20s. During the
day Monday, we'll have increasing clouds and moisture ahead of 
next system. Have chance of light rain mentioned late Monday 
beginning in our southwestern zones, but more persistent 
precipitation will move into our area overnight. Temperatures 
will be mild on Monday with southerly flow and warm air 
advection pushing temps into the 30s areawide.

&&

.SHORT TERM /MONDAY NIGHT THROUGH TUESDAY/...
As of 251 AM EST Sunday...Widespread precip event expected
Monday night into Tuesday across our cwa. Synoptic scale setup
shows southern stream shortwave energy moving across the MS
River Valley will enhance sfc low pres near the IN/OH border by
00z Tues. This sub 1000mb low pres will quickly track east
across northern NY/VT Monday Night into Tues. Strong low to mid
level waa lift/moisture associated with 50 to 60 knots southwest
850mb jet will produce widespread precip overnight Monday into
Tues. Once again sfc to 700mb thermal profiles are complex,
making for another challenging mixed precip event. Given deep
dry layer as precip arrives btwn 00z-04z Tues, column will cool
enough to produce a burst of wet snow in most locations. High
resolution NAM/NAM 3km and BTV 4km support this thinking, with a
quick dusting to an inch possible. Meanwhile, soundings show
several warm noses developing at BTV btwn 06-09z as 750mb temps
climb to +4c, with another warm layer around 900mb of 1 to 2c.
This combined with developing southerly winds of 10 to 20 knots
in the bl supports snow quickly changing to a cold rain in the
CPV/southern SLV, and Western Dacks. Position of sfc high pres
east of cwa, instead of north results in less low level CAD
signature in pres fields, but thinking moderately strong
southeast upslope winds will help keep cold air locked in place
on east side of the Greens for an extended period of mix precip.
Interesting, the fast moved of system cuts off warm nose from
reaching northern VT, especially northeast Kingdom, where 925mb
to 850mb profiles stay at or below 0c, supporting mostly snow.
Thinking a plowable snowfall of 3 to 6 inches is likely for
central/northern VT, especially the northeast Kingdom for this
event. Given snow ratio's starting 10/12 to 1 and dropping to 8
to 1, the wet snow could causes some isolated power outages. For
northern NY dusting to an inch or two of snow is likely, before
warm nose arrives and precip changes to rain with pockets of 
freezing rain. Some minor ice accumulation possible eastern 
Dacks, northern SLV, and central/southern VT. The main impact
from ice will be slipper travel, not enough ice accumulation
expected to cause power issues. Temps cool initial into the
upper 20s to l/m 30s, but warm into the mid/upper 30s northern
NY/CPV and hold steady east of the Greens on Monday Night.

By Tuesday, steadier and heavier precip quickly shifts east, as
mid/upper level dry slot develops. Expect storm total qpf of
0.40 to 0.75. As 995mb low pres moves into central Maine by 18z,
winds shift to the northwest and moderate 925mb to 850mb cold 
air advections. This will quickly change any mixed precip over 
to snow showers as 925mb to 850mb temps fall below 0c. Areal 
coverage of snow showers will become trrn focused as deeper 
moisture and lift is limited. Several inches of backside upslope
snow showers possible, which is supported by local BTV 4km 
data. Temps start in the mid 30s to lower 40s, but fall back 
into the 20s by late in the day on brisk northwest winds of 15 
to 25 knots. 

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 251 AM EST Sunday...Some changes noted in the 00z guidance
with regards to end of the week system. The 00z ECMWF/GEM/FV3
have trended north with southern stream system, resulting in
greater chances for precip. Given trends in guidance have bumped
pops into the likely range for Friday. Still plenty of
uncertainty on exact track of sfc low pres and amount of
southern/northern stream phasing. In addition, thermal profiles
would support another mixed precip event. ECMWF is most
aggressive with closed 5h/7h circulation passing to our south
with 986mb low pres over the Cape Cod Canal at 18z Friday. This
would advect plenty of deep moisture and lift across our cwa,
while 925mb to 850mb thermal profiles support the rain/snow line
over northern NY. Meanwhile, the GFS shows limited phasing and
keeps southern stream system suppressed, supporting just some
snow shower activity. The FV3 seems like a nice compromise btwn
the robust ECMWF and suppressed GFS solution, supporting a
quick moving low pres passing to our south. This would place our
cwa in a tight nw to se qpf gradient along with colder thermal
profiles for mainly snow. For now have increased pops to likely
and mention rain or snow based on uncertainty in thermal
profiles. Otherwise, mid week is quiet with temps near normal.

&&

.AVIATION /08Z SUNDAY THROUGH THURSDAY/...
Through 06Z Monday...Trying to time lower clouds finally 
dissipating across the area before next deck of clouds moves in 
towards morning. Some stubborn lower clouds still remain across 
much of the area at 1230 am. Drier air aloft will eventually 
scour out these clouds. VFR conditions begin Sunday at 12Z, but 
as the day goes on current MVFR over southwest NY and OH/PA will
begin to shift north and enter the region from southwest to 
northeast after 18Z. Winds trend light and variable, then shift 
to the SSW at 5-10kts beyond 16Z Sunday.

Outlook...

Monday: VFR. NO SIG WX.
Monday Night: Mainly MVFR, with local IFR possible. Definite RA,
Definite FZRA.
New Years Day: Mainly MVFR, with local IFR possible. Likely RA,
Likely SN, Likely SHSN.
Tuesday Night: Mainly VFR, with local MVFR possible. Chance SHSN.
Wednesday: VFR. NO SIG WX.
Wednesday Night: VFR. NO SIG WX.
Thursday: Mainly VFR, with local MVFR possible. Slight chance
SHSN.
