Area Forecast Discussion
National Weather Service Burlington VT
409 AM EDT Wed Mar 29 2017

.SYNOPSIS...
Deep low pressure over central Quebec this morning will continue
to provide abundant cloud cover to the North Country today,
along with areas of fog and drizzle this morning, and some
scattered rain and snow showers across north-central Vermont
this afternoon. A brief period of sunnier and drier conditions
is expected on Thursday as a ridge of high pressure builds over
the region, but unsettled weather returns for the end of the
week and into the weekend, as another storm system will bring
valley rain and mountain snow Friday into Saturday.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 408 AM EDT Wednesday...Deep low pressure over central 
Quebec this morning continues to provide abundant low level 
moisture to the North Country in the form of areas of cold 
drizzle and fog with current temps ranging through the 30s. Cold
air advection continues through the day on northerly flow, and 
while precipitation chances generally wane across the majority 
of the region, additional shortwave energy rounding the base of 
the upper trough will skim along the international border 
maintaining the threat for scattered valley rain and mountain 
showers across central and northern portions of Vermont through 
the afternoon. Abundant cloud cover will persist through the day
as well, keeping temps in the mid 30s to low 40s in the valleys
while the higher summits gradually fall through the 20s.

For tonight, the upper trough finally begins to swing east of 
the area with surface high pressure and and upper ridging over 
the Great Lakes and Ohio Valley edging ever so slowly eastward 
towards the region. Low levels finally begin to dry out with 
subsidence aloft winning out, so a gradually clearing of skies 
is expected though mainly after midnight with valley locales 
clearing the most, mountain areas less so. Lows will range 
mainly in the 20s with some teens in the Adirondacks.

Thursday will be the best day of the week as the aforementioned
high centers over the Northeast with skies continuing to clear 
through the day. Unfortunately temps won't really change to much
as weak cold air advection will continue on light northerly 
flow, but we should realize widespread highs in the low/mid 40s.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 341 AM EDT Wednesday...Most active period of weather then
affects the region by late Thursday night and especially Friday
into Friday night as upper closed energy tracks east from the 
Ohio Valley into the Mid Atlantic region. The forecast remains 
quite complex in regard to precipitation timing, amounts and 
type with lower boundary layer thermal profiles playing a 
critical role through the period. This is not uncommon with 
early spring systems with subtle changes of 1 to 2 degrees 
either way potentially leading to large differences in sensible 
weather. For now will maintain our prior idea of snows arriving 
into our southwestern counties later Thursday night into mid 
morning on Friday before a transition to all rain in lower 
elevations, or rain/snow mix from 1000-2500 feet on Friday as 
precipitation shield advances into the remainder of the forecast
area. At higher elevations above 2500 feet p-type may remain as
all snow. Negligible amounts of sleet or freezing rain is 
expected. Lows Thursday night mainly in the 20s with afternoon 
highs on Friday from 35 to 40 below 1500 feet and 30 to 35 above
that level. 

Bulk of precipitation then affects the area Friday night as warm 
thermal advection aloft will be peaking and as thermal profiles cool 
slightly a transition to all snow is expected after midnight. 
Amounts may be a bit tricky as flow trends southeasterly and some 
slight shadowing effects may occur. Time will tell. I was also 
cautious in leaning too high on our QPF given known model high bias 
during warm thermal advective events. Nonetheless the potential will 
exist for a light to moderate wet snow accumulation in many areas 
with higher amounts possible in elevated southern terrain. Did lean 
on the milder side of guidance given clouds and lack of appreciable 
low level advection - mainly lower to mid 30s (upper 20s at 
elevation). Please see our winter weather page at 
www.weather.gov/btv/winter for specific accumulation forecasts and 
probabilities.

By Saturday widespread light snows taper to scattered rain/snow
shower activity as system exits the Mid Atlantic coast and 
gradually loses influence. Any additional snow accumulations 
will be minor as late day temperatures top out in the upper 30s 
to lower 40s.

&&

.LONG TERM /SATURDAY NIGHT THROUGH TUESDAY/...
As of 341 AM EDT Wednesday...Relatively quiet weather then 
returns by later Saturday into early next week with mean high 
pressure building back across the region. Any lingering 
rain/snow shower activity will wane in coverage, becoming more 
confined to northern higher terrain into Sunday as highs top out
in the 40s. Temperatures will be similar on Monday with dry 
weather expected. The next threat of steadier precipitation 
potentially arrives toward the middle of next week with chances 
of rain and/or snow showers. Temperatures will remain at, or 
slightly above seasonal early April norms.

&&

.AVIATION /08Z WEDNESDAY THROUGH SUNDAY/...
Through 06Z Thursday...Variable flight conditions from VFR to
LIFR will continue through 12-13z before all sites lift to MVFR
except VFR at KMSS. Thereafter a gradual improvement at all
sites to VFR is expected by the afternoon. Areas of fog and
drizzle overnight generally dissipate after 12z as well, with
some lingering rain/snow showers across central/northern
portions of Vermont through about 18z. Winds calm/light
overnight trend to the north/northwest at 5-15kts after 12z with
some gusts up to 20kts possible from the Champlain Valley
eastward through Vermont.

Outlook 06Z Thursday through Sunday...

06Z Thursday through 12Z Thursday...Mainly VFR. Isolated MVFR 
and showers over higher terrain of NE VT.

12Z Thursday through 12Z Friday...VFR under high pressure.

12Z Friday through 00Z Monday...MVFR/IFR in periods of rain and
snow.

.BTV WATCHES/WARNINGS/ADVISORIES...
VT...None.
NY...None.
