AREA FORECAST DISCUSSION
National Weather Service Burlington VT
643 AM EST Thu Dec 13 2018
.SYNOPSIS...
A weak disturbance aloft passing to our south may provide a few snow
showers and or flurries to the region today, but generally dry
conditions are expected as surface high pressure off the New England
coast dominates. An upper trough passing north of the region will
bring a chance of rain and snow showers late Friday afternoon and
early Friday night, before dry conditions return again for Saturday
and Sunday. Temperatures will be below normal today, but warm into
the 30s and 40s for Friday and the weekend.
&&
.NEAR TERM /THROUGH FRIDAY/...
As of 643 AM EST Thursday...No major updates needed to this
mornings forecast other than to tweak temps to match current
observational trends. Current spread of temps across the region
range from -26F at Island Pond Airport to +23F atop Whiteface
Mountain. Crazy.
Prior Discussion...
Mid/upper level ridge and surface high pressure over the region
this morning continues to provide bone- chilling temperatures
for many locations with the coldest spot in the BTV CWA being
Island Pond airport reporting -21F as of 2 AM. Many locations
are in the single digits to teens below zero, but where winds
didn't decouple and high clouds moved in temperatures have
remained steady or slowly risen into the single digits to teens
above zero. Warmest spot in the CWA, oddly enough, is the top of
Whiteface Mountain coming in at +21F at 2 AM, which was
actually well forecast by hi-res model soundings which showed
warming during the overnight at 850mb.
To our south, a weak shortwave aloft is providing enough moisture
and lift to produce some snow showers across western New York, and
as this feature pivots across the Mid-Atlantic states today, we may
see a few snow showers and/or flurries across central/southern
portions of the North Country, but no accumulations are expected.
Most areas will likely remain dry with temps rebounding nicely into
the mid 20s to low 30s. For tonight, dry conditions continue as
upper ridging redevelops in the wake of the exiting shortwave, and
surface high pressure very slowly shifts offshore to our east.
Despite very dry mid/upper levels, a weak subsidence inversion will
keep skies rather cloudy and will hold temps in the teens to 20s
overnight. Expect the highest summits of the Adirondacks to poke
above the clouds though.
On Friday we'll see generally dry conditions continue through much
of the day until the afternoon when chances for rain/snow showers
increase as warm air advection develops from the south and an upper
trough approaches from the north. Southerly winds will increase
markedly into the 10-20 mph range and warm the boundary layer well
into the 30s with some locations pushing 40 degrees.
&&
.SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY/...
As of 256 AM EST Thursday...Trends in the data continue to support
the idea that we will be more influenced by northern stream
shortwave rather than larger upper circulation to our south. This
will keep precipitation on the lighter side and best chances for
precipitation will be over our northern areas. Thermal profile
suggests precipitation will be in the form of rain or snow as cloud
cover and warmer temperatures aloft keep lows generally in the 30s
Friday night. West to northwest flow aloft develops over the area on
Saturday and its now looking like a mainly dry day with highs in the
upper 30s to lower 40s.
&&
.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 256 AM EST Thursday...Most areas remain dry on Sunday but we
could see some moisture moving up from the south late in the day and
Sunday night which could bring some precipitation to our southern
areas. Better chances for precipitation look to be later on Monday
and Monday night as shortwave trough drops down out of Canada.
Thermal profile suggests mainly snow on Monday with some rain mixing
in across the larger valleys...but as cold air advection get
established Monday night the precipitation would be in the form of
snow. Northwest flow aloft Monday night would also tend to start
focusing any precipitation over the northern Adirondacks and the
northern half of Vermont. Could see some light accumulations. Snow
showers will linger in the mountains on Tuesday before high pressure
builds in Tuesday and Wednesday for a return to dry weather. Sunday
looks to be the warmest day with highs in the 30s...then as clouds
and precipitation move in on Monday highs will be in the low to mid
30s and with cold air advection on Tuesday highs will only be in the
upper teens to mid 20s. More sun on Wednesday will lead to some
warmer temperatures with highs in the mid 20s to lower 30s.
&&
.AVIATION /12Z THURSDAY THROUGH MONDAY/...
Through 12Z Friday...Mainly VFR conditions are expected through
the period with brief MVFR possible across northern New York.
High cirrus deck building in from the southwest will continue
to shift northeast across the region this morning while
gradually lowering to a mid deck around 12kft. Exception will be
KPBG where a lake induced IFR/MVFR deck will persist for a few
more hours before lifting to VFR. For this afternoon, upstream
obs still show MVFR over the eastern Great Lakes and these
clouds may shift into northern New York affecting KMSS and KSLK
for a brief period before shifting south of the region this
evening. Elsewhere, VFR will prevail with cigs lowering to just
above the mountain tops by the afternoon and remain there
through the overnight. Light and variable winds this morning
trend southerly at less than 10 knots after 12Z and through the
remainder of the period.
Outlook...
Friday: Mainly VFR, with areas MVFR possible. Chance RA, Slight
chance SHRA.
Friday Night: Mainly VFR, with areas MVFR possible. Chance RA,
Slight chance SHRA.
Saturday: Mainly VFR, with local MVFR possible. NO SIG WX.
Saturday Night: VFR. NO SIG WX.
Sunday: VFR. NO SIG WX.
Sunday Night: VFR. Slight chance SHSN.
Monday: Mainly MVFR, with local IFR possible. Chance SHSN.
