Synopsis
Line of showers and thunderstorms will clear the area this
evening, followed by a mainly dry... But warm... Night. A cold
front will move through Thursday morning, bringing a few showers
to the north country. The front will be followed by building
high pressure that will bring noticeably cooler and drier
conditions for the remainder of the week.

Near term through Thursday night
As of 325 pm edt Wednesday... Final line of
showers thunderstorms is moving through the area as of 330 pm,
progged to clear the area by around 6 pm or so. Still a brief
window for some thunderstorms in the albany ny vicinity to move
eastward and skirt southern rutland and southern windsor
counties in vermont... Bringing some locally heavy rainfall and
gusty winds. However, the more widespread thunderstorm activity
this afternoon will remain to the south of the forecast area.

Redevelopment behind this line looks unlikely given waning
instability and loss of forcing.

Brief window of subsidence over the region behind the exiting
upper wave will allow precipitation to diminish this evening. In
addition, drier air aloft wrapping into btv forecast area
around a low pressure system over quebec... Leading to clearing
skies and brief overnight drying trend. The system's cold front
will still be to our northwest overnight, so looking at some
continued weak warm air advection that will keep lows in the mid
60s. We could also see some low clouds lingering, especially in
higher terrain, with some localized areas of mist and or fog
developing.

Cold front will move through late Thursday morning, but an
uneventful frontal passage is expected due to lack of moisture
and instability. Will see a few showers develop as the boundary
passes through, but nothing more than that. Behind the frontal
passage, will see some breezy westerly northwesterly winds
develop with temperatures dropping through the afternoon. High
temperatures will be in the mid 70s along the international
border and in the upper 70s to low 80s further south.

High pressure will build in Thursday night, keeping the area
dry. Lows will generally be in the low to mid 50s.

Short term Friday through Friday night
As of 414 pm edt Wednesday... Upper level trough will push east
across our area Friday and will have just a tiny chance for
showers associated with this feature especially across
northeastern vermont. Very limited moisture so really don't
think we'll see much more than clouds with the upper trough
passage. Temperatures will be pretty cool on Friday, upper 60s
to lower 70s. Weak surface trough will also cross the area
Friday and flow will become more northwesterly behind this
surface feature. Overnight lows will be in the mid 40s to lower
50s, a few degrees below seasonal normals as large ridge of
surface high pressure begins to build into the region.

Long term Saturday through Wednesday
As of 414 pm edt Wednesday... The extended portion of the
forecast continues to look pretty quiet. High pressure and dry
weather will be over the area from Saturday through Tuesday.

Next frontal passage will be somewhere towards the middle of the
week, probably Tuesday night into Wednesday.

Aviation 20z Wednesday through Monday
Through 18z Thursday... Continuing to see scattered showers
across the area this afternoon leading to some localized MVFR
visibilities and ceilings. Potential for some showers with some
isolated thunderstorms continues through mid afternoon, but have
kept mention out of most of the tafs due to low confidence. The
exception will be krut, where there is higher confidence in
thunderstorms moving through between 20z and 22z. These
thunderstorms may contain gusty winds and locally heavy
rainfall. Conditions will return to widespreadVFR tonight,
though fog mist development is possible at slk mpv 05-12z
Thursday.

Winds will generally be southerly under 10 kts through 00z,
then turn westerly 5-10 kts through the night.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
