Area Forecast Discussion
National Weather Service Burlington VT
625 AM EST Wed Nov 11 2020

.SYNOPSIS...
A weak cold front will cross the region today bringing 
scattered light rain showers to the region. Behind the front a 
return to cooler, more seasonable weather is in store for late 
week. The next chance of showers occurs by early next week in 
association with additional frontal energy.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 618 AM EST Wednesday...An area of rain showers has begun
to move into the St Lawrence valley early this morning, this is
a bit earlier than anticipated. Have updated pops and weather
grids to reflect that. Mid level clouds have moved into the
central Vermont area as well. Otherwise, no changes to the going
forecast. Previous discussion follows. 

Scattered light rain showers spread across our region today as 
a cold front approaches from the west. Most of the showers will 
be out ahead of the cold front, which will cross our area from 
about 21-06z with a fine line of showers. We will not see a lot 
of precipitation with this system as best dynamical support 
remains well north of our region, and best moisture will be to 
our south. Showers will spread into our Northern New York zones 
in the 13-16z timeframe, the Champlain valley in the 16-19z 
timeframe, and then eastern Vermont from 19-22z. As mentioned, 
will probably see a more distinct fine line of showers with 
actual fropa which will exit our forecast area by about 06z. 
Rainfall totals will range from just a few hundredths of an in 
up to about a quarter of an inch. Some higher elevation regions 
in Southern Vermont could see a bit more. We will have strong 
southerly winds today before the precipitation begins, 
especially in the Champlain valley and on and along Lake 
Champlain. Winds will gust to 30 kts at times. Temperatures will
also be pretty warm this morning ahead of the precipitation 
beginning, currently only 64 degrees at BTV, so I'm still 
confident that we'll reach 70 before the precipitation begins 
despite lack of sunshine. 850 mb jet of about 45 to 50 kts will 
cause some shadowing effects downwind of the Dacks and Greens. 
Behind the departing cold front precipitation should shut down 
pretty quickly. Our winds will turn to westerly, then continue 
to veer to northwesterly then northerly on Thursday. Thursday 
will feature slightly warmer than normal temperatures, but will 
feel pretty cool after the stretch of abnormally warm 
temperatures we just experienced.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH FRIDAY NIGHT/...
As of 415 AM EST Wednesday...By far the coldest night so far this
week is expected Thursday night given light winds, dry air, and a
more seasonable air mass in place. Low temperatures in most areas
will range from the mid 20s to low 30s. High pressure overhead will
gradually retreat to our northeast which will allow light winds to
shift direction from northerly to easterly during the overnight
hours. By Friday morning, a potent, compact shortwave trough will be
near the North Country, providing upper-level divergence that will
promote cyclogenesis somewhere in the Mid-Atlantic and the resulting
low pressure area will move northeastward spreading an area of rain
into New England during the afternoon. Winds will pick up out of the
southeast to south and low clouds along with a narrow axis of
moderately deep moisture will be ushered into southern portions of
Vermont and the Adirondacks before pushing farther north and east.
While eastern Vermont is still most favored to see rain, how far
west the back edge goes is still uncertain. At this time, 
expecting Windsor and Rutland counties to see upwards of 0.1" of
light rain during the morning and then even lesser amounts 
spread northeastward over eastern Vermont through the afternoon.
While precipitation may start as snow in the higher terrain, 
accumulation is not expected before a changeover to rain. 
Temperatures will be somewhat dependent on the cloud cover and 
precipitation, so it will be chillier in many areas of southern 
and eastern Vermont than farther north and west.

&&

.LONG TERM /SATURDAY THROUGH TUESDAY/...
As of 415 AM EST Wednesday...A brief cool down to near normal
temperatures through Saturday night will take place behind a cold
front that passes by Friday night. However, with heights building
behind the front and shortwave trough lifting quickly to our
northeast, the weather should be pleasant with modest (< 10 MPH)
west winds and partly cloudy skies. Enjoy the calm while it lasts,
as an active period will follow for the rest of this period with
precipitation and lowering temperatures from above normal on Sunday
to below normal on Tuesday.

A round of strong south winds will develop on Sunday well ahead of a
vigorous storm over the Great Lakes. While model agreement has been
improving, still kept chances below likely with various details
unclear at this time. Generally it looks at if rain, likely
beginning as snow given below freezing low-levels over the North
Country Sunday morning, will spread across most areas by evening.
The rain stabilize the boundary layer so winds should relax once the
rain moves in, but the south wind will keep temperatures and dew
points mild through much of Sunday night.

On Monday, cold cyclonic flow to the south of the deep low pressure
area over eastern Canada should promote lake effect precipitation
downwind of Lake Ontario on Monday. Strong cold air advection will
enhance instability over the Great Lakes, although temperatures near
the surface will support mainly rain at first. A west-southwest wind
along with falling snow levels, however, would support snow over at
least the higher elevations of the Adirondacks and into the Greens,
especially towards Monday night. This threat will need to be
monitored closely, as it hinges on having a vertically stacked low
pressure system more similar to what the CMC depicts as opposed to a
weaker, progressive low pressure system like what the GFS shows at
this time. Outside of the lake-effect snow potential, we should see
periods of upslope snow through Tuesday as the core of an Arctic
blast moves into the North Country with gustier west to northwest
winds. Temperatures will likely peak in the upper 20s to mid-30s,
about 10 degrees lower than on Monday, as another taste of 
winter returns.

&&

.AVIATION /11Z WEDNESDAY THROUGH SUNDAY/...
Through 12Z Thursday...A bit of a challenging TAF forecast. Have
timed showers to move into the region from west to east today.
We also have some gusty winds in the Champlain valley at BTV and
PBG. Some MVFR cloud decks have moved into the MPV and RUT area.
Ceilings should lower areawide to 2000-3000 ft at all sites 
mid morning. Rain should be pretty light, therefore don't
expected visibilities to drop below 6sm most of the time. Winds
mainly light to moderate southerly through the forecast period,
occasionally gusty during daylight hours at favored terminals. 
Southwesterly LLWS from 35 to 45 kts the primary concern today 
at most terminals. Precipitation should be ending by about 06z
across all terminals.

Outlook...

Thursday: VFR. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: Mainly VFR, with local MVFR possible. Slight chance RA.
Friday Night: MVFR. NO SIG WX.
Saturday: Mainly VFR, with local MVFR possible. NO SIG WX.
Saturday Night: VFR. NO SIG WX.
Sunday: VFR. Chance SHRA, Slight chance SHSN.
