Area Forecast Discussion
National Weather Service Burlington VT
406 AM EST Thu Nov 15 2018

.SYNOPSIS...
High pressure today gives way as an advancing winter storm will
bring widespread moderate and, at times, heavy snow to the 
North Country Thursday night into Friday morning. Winter Storm 
Warnings and Winter Weather Advisories are in effect for the 
North Country. Expected snow totals range from 4 to 9 inches 
through mid day on Friday with another round of light snow 
Friday night. Quiet weather returns coming out of the weekend as
a cold airmass moves in during the middle of next week.

&&

.NEAR TERM /THROUGH FRIDAY/...
As of 335 AM EST Thursday...Winter Weather Advisories have been
upgraded to Winter Storm Warnings for the Northern Adirondacks 
and for the Northeast Kingdom. All other Winter Weather 
Advisories remain in effect.

High pressure will slowly drift off to the north and east this 
afternoon as our next winter storm will push into the region. WV
satellite shows a mature cyclone over western Kentucky with a 
strong baroclinic leaf stretching out over the North Country. 
This system will merge energy with a developing coastal low by 
midday and end up pushing widespread precip into the region late
this evening. Thermal profiles support all snow at the onset 
and so we should be looking at a pretty good thump of snow. 
Omega in the dgz is impressive as the warm advection snow starts
and we should see full saturation in the -12C to -18C snow 
growth zone. That combination of RH and vertical lift should
result in some modest sized snow flakes mixing in. Current 
thinking is that snow ratios will be in the 10-11:1 range for 
the warm advection burst and then will switch around to 13-15:1 
once low pulls to the northeast Friday morning into the 
afternoon hours.

The biggest reason for the upgrade to warning level snow is 
that models are continuing to converge on the idea that a strong
band of snow will lift into the region between 03-15z. With 
strong lift and a pronounced 700mb f-gen band pivoting across 
the Adirondacks into the Northeast Kingdom its reasonable to 
expect 1-2" inch an hour rates for at least 4-6 hours during 
the late night hours Thursday night. Picking out exactly where 
the band develops and pivots is still a challenge but its 
looking like a sure thing that a strongly forced meso band will 
drop some pretty heavy snow in a short period of time. This will
likely lead to some isolated power outages and will certainly 
make travel difficult especially during the Friday morning 
commute. The highest qpf totals fall from around 6-12z where 
region wide we'll be looking at between 0.25-0.5" of liquid 
equivalent.

The fly in the ointment with this system however is the warm 
nose and dry slot. There's pretty consistent signal in all the 
models that a dry slot will develop somewhere along southern 
New England and potentially push into southern Vermont. The warm
nose never really gets into the region so it will be cold 
enough for snow everywhere. The problem is that most of the 
guidance does show the mid level dry slot punching into the snow
growth zone for southern Vermont between 9-15z. I leaned away 
from the drier NAM and more towards the GFS and our local 
4kmwrf which hold on to RH a tad longer but either model you 
pick it still shows some dry air moving in aloft. So the net 
effect of that is that instead of ice crystals growing aloft 
we'll see the sounding have supercooled water falling. So there 
may be some periods over southern Vermont early Friday morning 
where some freezing drizzle is mixing in instead of pure snow. 
Its certainly something to keep and eye on and how does that 
affect the snow totals. That area is in an advisory for 4-6 
inches but its certainly possible this system under performs 
there.

So all totaled we'll be looking at widespread 4-8 inch snowfall
with local amounts of 8-10 possible with most of that coming 
within the first 6-8 hours of precip onset. The key messages 
will continue to remain that its early in the season and so 
travel will be difficult especially Friday morning and that with
heavier wet snow may lead to some isolated power outages.

&&

.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/...
As of 404 AM EST Thursday...During Friday night, the deep 
surface low will be pulling away from New England south of Nova 
Scotia. However, it continues to appear that in strong mid-level
zonal flow that follows, two trough axes will progress through 
northern New York and Vermont. The first brings periods of 
mainly orographic snow shower activity across the Adirondacks 
and central/nrn Greens. The second is a 700-500mb vorticity 
maximum and reinforcing sfc cold front approaching from Ontario 
that passes through the region between 15-21Z Saturday. The 
front will likely bring additional scattered convective snow 
showers or a few snow squalls for a period of time Saturday, 
with steep low-level lapse rates in place. Overall snowfall amts
will be light Friday night and Saturday, totaling generally a 
dusting to 2" between the two light events, with slightly higher
amounts possible with orographic enhancement across the nrn 
Greens. Moderate westerly winds of 10-15 mph with gusts to 25 
mph Friday night will keep overnight temperatures from falling 
very quickly, with early Saturday AM lows mainly upr 20s to 
lower 30s for the North Country. Saturday will feature continued
westerly winds, with a nwly wind shift following FROPA and 
temperatures generally steady in the 30s. Should see a trend 
toward lighter winds and cessation of snow shower activity 
Saturday night as sfc anticyclone across the Great Lakes begins 
to build ewd across New York and New England. A better 
radiational cooling night is forecast, with lows mainly in the 
teens, except lower 20s in the Champlain and upper CT valleys.

&&

.LONG TERM /SUNDAY THROUGH WEDNESDAY/...
As of 404 AM EST Thursday...A quieter weather pattern is 
forecast for the long-term, with just northern stream shortwave 
troughs bringing potential for light snow showers Monday and 
Tuesday. Overall temperature conditions remain below normal for 
mid-November, with valley highs in the low-mid 30s for Sunday 
and Monday. A cold front moves through Monday night/Tuesday, 
with temperatures possibly trending back into the mid- upr 20s 
for highs on Tuesday and Wednesday of next week. This will again
be 10-15deg below normal. Early indications suggest mainly fair
and seasonably cold conditions continuing for Thanksgiving Day.

&&

.AVIATION /09Z THURSDAY THROUGH MONDAY/...
Through 12Z Friday...VFR conditions and light winds will 
continue through the day on Thursday before widespread IFR/LIFR 
snow moves into the North Country overnight Thursday night. 
Winds will begin to shift from the NW to the S over the course 
of the day Thursday. 

Outlook...

Friday: Mainly MVFR and IFR, with local VFR possible. Definite
SN, Definite RA.
Friday Night: Mainly MVFR, with areas VFR possible. Chance SHSN.
Saturday: Mainly MVFR, with areas VFR possible. Chance SHRA,
