Area Forecast Discussion
National Weather Service Burlington VT
631 AM EST Tue Nov 17 2020
.SYNOPSIS...
A cold front will cross the area today into this evening along
with variable clouds and scattered flurries, mainly across
higher terrain. Expect a chilly day on Wednesday behind the
front, after which temperatures moderate considerably by
Thursday into next weekend as south winds return. The next
chance of significant precipitation occurs by Sunday night into
Monday.
&&
.NEAR TERM /THROUGH WEDNESDAY/...
As of 630 AM EST Tuesday...The forecast remains largely in good
shape as of 600 am. I did put in a 1-3 hour window of higher
shower chances through late morning across central/northern
counties along a pre-frontal convergence line dropping southward
this morning, evident as a line of snow showers across
northeastern NY into the northern Champlain Valley and portions
of nc/ne VT. Within this band, brief visibility restrictions to
below 2 miles are likely, though with sfc temperatures aoa
freezing little to no impacts are expected. Otherwise, just some
minor cloud coverage adjustments were made to line up with
current observational trends. Have a great day!
Prior discussion...
Variable clouds will be the rule over the next 36 hours as a
cold front crosses the region. Deeper moisture is lacking with
with this feature, so only low to slight chance PoPs (10-30%)
will be offered today with any minor accumulations occurring in
elevated terrain (< 1 inch). High temperatures to hold steady
this morning (30s to around 40), then slowly fall this afternoon
as flow veers northwesterly over time behind the boundary.
By tonight the front clears well south and east of the area.
However, models generally concur that ample moisture in the lower to
mid levels will become trapped beneath a building synoptic inversion
near 850 hPa. As such, while the broad valleys will likely trend
partly cloudy, higher terrain will likely hold on to ample cloud
cover with some scattered flurry activity here and there owing to
the above reasoning and some lightly forced orographic effects. This
appears reasonable given this is a common occurrence during post-
frontal northwest flow regimes and current upstream clouds across
southern Canada. Given the expected cloud cover I ended up raising
minimum temperatures by 1-3 degrees in our colder northern mountain
locales.
Then variable clouds/mtn flurries thin/end by Wednesday morning,
with partly to mostly sunny skies expected by afternoon as high
pressure builds eastward. This will be the coldest day of the week
with mean 925 hPa temps hovering only around -10C supporting highs
only in the 20s to locally around 30.
&&
.SHORT TERM /WEDNESDAY NIGHT THROUGH THURSDAY/...
As of 250 AM EST Tuesday...Last chilly night in store for the
short/extended period on Wednesday. Temperatures should drop
pretty rabidly for the 1st half of the night before clouds and
southerly winds increase after 06z. Hollows across the
Adirondacks and eastern VT will see the coldest readings in the
upper single digits/low teens, with mid teens to around 20
elsewhere. As warm front begins to push northward expect cloudy
skies throughout the day Thursday. Temperatures will be near to
slightly below normal from west to east, with warmest readings
across the St Lawrence Valley (mid/upper 40s) and coolest
readings (mid/upper 30s) for far eastern VT/Northeast Kingdom.
Despite fairly normal readings, southerly winds will increase
during the day Thursday around 10-15 mph (20-25 mph over Lake
Champlain) which will make for chillier conditions.
&&
.LONG TERM /THURSDAY NIGHT THROUGH MONDAY/...
As of 250 AM EST Tuesday...Overall, relatively quiet period of
weather through the weekend. Zonal flow aloft will continue to
bring several impulses across the North Country, however expect
only an increase in cloudiness as available moisture is lacking.
Surface boundary begins to sink south of southern Quebec
Saturday. A few sprinkles may be possible with this boundary,
but expect largely dry conditions. Near to slightly above
seasonable temperatures in the mid 40s/low 50s are expected
Friday - Sunday. Our next system begins to approach from the
west Sunday, with breezy southerly winds increasing throughout
the day. Surface cold front moves through Monday
morning/afternoon. P-type is looking like rain at this point
outside the highest terrain with a chance for some scattered
snow showers late Monday night as surface front pulls away to
the east.
&&
.AVIATION /12Z TUESDAY THROUGH SATURDAY/...
Through 12Z Wednesday...Mainly VFR expected over the next 24
hours as cold front crosses the region this afternoon. BKN/OVC
cigs generally in the 035-070 AGL range expected through through
the period, with some occnl partial breaks at favored terminals
of KMSS and KPBG. Scattered flurries likely through much of the
forecast period in higher elevations/KSLK with a brief 1-3 hour
window of MVFR/brief IFR -shsn possible at KSLK/KPBG/KBTV/KMPV
through late morning/early afternoon as front passes. Winds
generally west to southwest 5-9 kts through 16Z, trending west
to northwesterly 6-12 kts thereafter behind the front.
Outlook...
Wednesday: VFR. Chance SHSN.
Wednesday Night: VFR. NO SIG WX.
Thursday: VFR. NO SIG WX.
Thursday Night: VFR. NO SIG WX.
Friday: VFR. NO SIG WX.
Friday Night: Mainly VFR, with local MVFR possible. NO SIG WX.
Saturday: Mainly MVFR, with areas VFR possible. NO SIG WX.
