Area Forecast Discussion
National Weather Service Burlington VT
642 AM EST Fri Jan 5 2018
.SYNOPSIS...
Strong low pressure will slowly pull away from the region through
Saturday with gusty winds, bitterly cold wind chills and areas of
blowing snow. Light snows will continue across the northern
mountains, where a few additional inches will be possible.
Temperatures begin to moderate by Sunday and will warm considerably
from Monday onward through the rest of next week with periodic
bouts of light precipitation.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 642 AM EST Friday...Minor updates were made to sky cover
and hourly temperatures/dewpoints to match current observational
trends. Some partial clearing has occurred in the St. Lawrence
Valley and temperatures have fallen a bit quicker than prior
indications. Falling temperatures and dangerously cold wind
chills continue to advect into the area this morning along with
considerable areas of blowing snow. When headed out this morning
please dress appropriately and make sure you have winter
weather safety items in your vehicle. Stay warm!
Prior discussion...
Deep, 950mb low pressure across New Brunswick will track
northeast into the Gulf of St. Lawrence by later today and
toward the Davis Strait region by Saturday. A modestly robust
pressure gradient will continue on the back side of this system
during this period supporting sustained wind speeds from 10 to
20 mph and gusts in the 20 to 35 mph range. These winds combined
with sharply colder temperatures will create dangerously cold
wind chills across the forecast area and all Wind Chill Warnings
will remain in place with this package. While sub -30F wind
chills will not be met in every location at all times, most
spots should see values occasionally below these levels by
tonight into Saturday.
In terms of snowfall, models remain consistent that light
accumulating snowfall will become increasingly confined to northern
counties, especially the northern mountains over the next 24 hours.
While there may be lulls in steadier activity from time to time, the
overall idea of cyclonic wrap-around moisture advecting southward
into these areas into tonight still looks good so have maintained
high pops accordingly. Additional accumulations of several inches
will be possible in favored upslope locales. As such we've opted to
extend the Winter Weather Advisory for the western slopes of the
northern Greens to include Lamoille County until 11 pm tonight, and
cancelled all remaining Advisories and Warnings.
Temperatures will go nowhere today under strong cold thermal
advection and actually slowly fall through time, leaving values in
the single digits below zero in most areas by mid to late afternoon.
The cold temperatures then continue tonight with average values by
Saturday morning generally in the -10F to -20F range. Saturday
should bare the brunt of the cold as lingering northern mountain
flurries/snow showers end. Modestly gusty west/northwest flow will
continue as highs range from -2F to -8F in the broad valleys and
from -6F to -12F across the northern mountains. Indeed a good day to
stay inside.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH SUNDAY/...
As of 333 AM EST Friday...By Saturday night sensible weather
finally calms down for a brief period as expansive 1040 mb polar
high settles across the entire east coast from Maine to
Florida. This will be our coldest night in the foreseeable
future as temperatures look to moderate considerably by next
week. For now have maintained consistency showing minimums in
the -15F to -30F range. Of course there will be variability as
always with radiative nights and locally colder values will be
possible in favored northern mountain hollows while slightly
milder readings are certainly plausible near the Lake Champlain
shore.
On Sunday we begin to turn the corner so to speak as temperatures
begin a long-awaited moderation. The process will be slow at first
so afternoon highs will still be on the chilly side, but at least
we'll be headed in the right direction. For now I've offered
readings from 5 to 10 above in eastern VT, 10 to 15 in the Champlain
Valley/Adirondacks and teens in the St. Lawrence Valley. Toward
day's end a warm front associated with an approaching weak northern
stream system will encroach into the region along with increasing
clouds and perhaps a few snow showers across northern and western
counties toward evening. Winds will trend southerly over time and
become gusty into the 20 to 30 mph range from the Champlain Valley
westward by afternoon.
&&
.LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/...
As of 200 AM EST Friday...Expecting some light snow Sunday night
with a warm front lifting through the area. More light snow
during the day Monday with a cold front crossing our forecast
area. Snow will become more orographically influenced going into
Monday night with front to our east and flow becoming
Northwesterly behind it. Snow showers will wind down during the
day Tuesday. During the Tuesday night through Wednesday night
time frame will have a much warmer high pressure ridge in place
compared to the past couple weeks. After this ridge pushes east
of us the weather becomes much more active and warmer from
Thursday onward. We could have some rain and thaw if the current
forecast holds up. Have gone warmer than super blend guidance
for Wed and Thu.
&&
.AVIATION /12Z FRIDAY THROUGH TUESDAY/...
Through 06Z Saturday...Snow will begin to become more terrain
focused today, but strong gusty winds will keep visibilities
variable through much of the day with blowing snow. Still
widespread MVFR with occasional IFR at best for much of the
daytime hours. Winds will remain gusty out of the northwest
through the period, with gusts up to 35 kts possible.
Outlook...
Saturday: Mainly VFR, with local MVFR possible. Chance SHSN.
Saturday Night: VFR. NO SIG WX.
Sunday: VFR. Chance SHSN.
Sunday Night: Mainly VFR, with areas MVFR possible. Chance SHSN.
Monday: Mainly MVFR and IFR, with local VFR possible. Likely SN.
Monday Night: MVFR and IFR. Likely SN.
Tuesday: Mainly MVFR, with areas VFR possible. Chance SHSN.
