1022 pm edt Fri aug 18 2017

The weekend will feature slightly unsettled weather Saturday
and Saturday night with a few light showers. Sunday will be
mostly sunny, dry and warm. That sunny and warm weather will
continue Monday, allowing for perfect conditions to view the
solar eclipse. Increasing chances for showers and thunderstorms
return for late Tuesday and into Wednesday.

Near term through Saturday night
As of 1022 pm edt Friday... Line of convection continues to move
into western champlain valley with waning instability. Expect
heavy showers to continue eastward into vermont but gradually
dissipate as the air over central and eastern vermont is not as
moist and lacking instability. Air behind this initial surface
trough producing showers continues to have relatively high
dewpoints, in the mid-upper 60s tonight. Temperatures will
remain mild and it will feel muggy. With the high humidity, we
may see a light fog haze develop in most areas overnight.

Perhaps a few patches of denser fog in eastern vermont.

Saturday: another day that will be on the slightly warm and
humid side, but not an uncommon mid-summer day. At upper levels,
there will be a trough off to our west, putting us in deep
southwest flow. However the mid upper levels will still be
relatively dry, so this will limit the potential for convective
activity. Hi-res models do indicate a few hit or miss (but
mostly miss) showers developing during the day. As such, have
some 20-35% pops, highest across the higher terrain of northern
vermont. High temperatures will be a few degrees above normal,
with upper 70s to lower 80s.

Saturday night: models all indicate the upper trough will be
passing overhead, and this passage will be accompanied by clouds
and a few light showers. Kept pops in the 25-35% range.

Short term Sunday through Sunday night
As of 350 pm edt Friday... If you love outdoor summer activities,
Sunday will definitely be a day to take advantage of it. Plenty
of sunshine, temperatures in the mid 70s to lower 80s, and most
importantly lower dewpoints -- all thanks to high pressure
ridging and a west northwest flow bringing in the drier air.

Long term Monday through Friday
As of 350 pm edt Friday... First... Eclipse. Partial for
cwa... Basically 58-65 percent. Sky conditions looking very
favorable. Partial begins at btv around 1725 utc and ends around
1953 utc according to nasa eclipse sight.

Zonal flow across area on Monday with surface high south of
area, this will eventually allow for some increased humidity and
clouds but really not til Tuesday. A pretty nice eclipse day
with highs in the 80s and sunshine.

The next system has been delayed as its awaiting a sharp, deep
shortwave from central canada to drop across the northern plains
Tuesday and then rotate across the great lakes Tuesday night
and lift NE into ontario quebec on Wednesday. The timing looking
like more of a Tue ngt-wed feature. However... Surface temps in
the m-u80s with rich dewpoints in the 60s and pwats approaching
1.75 inches should produce sfc based capes in the 1000-1500
range at least. Also... Despite the main dynamics and surface
front still across the great lakes, there are falling
heights... Diffluent flow aloft and indications of some pre-
frontal trof, thus chance for t-storms will increase toward
evening... ESP ny and intl border. Wind dynamics don't look too
favorable and timing may just be too late but still worth
watching as they will increase Tue ngt.

Leading, strong shortwave and surface front move through tue
ngt- midday wed. By Wed aftn... Front should be just east of cwa.

Trof axis still west of CWA Wed ngt-thu with surface high still
west as well. Therefore, some unstable flow but pwats fall to
around 0.50 inches on thu. Current thinking is largely mountain
upslope shower sprinkle. Highs on Thu l-m70s.

Thu ngt-fri deep trof axis passes area with surface high
pressure building into region thus primarily dry and cooler
temperatures. Highs in u60s-l-m70s. A cool start with lows in
the 40s 50s and some possible upper 30s. Friday ngt-sat morning
should be as cool or cooler.

Aviation 02z Saturday through Wednesday
Through 00z Sunday... We'll continue to see a mix of aviation wx
conditions across the north country during the overnight hours.

Stratus deck remains in place east of the green mtns, and
should continue to hold thru the overnight period, with ceilings
ranging from 500 to 1500 ft with trrn obscd. Better mixing west
of the green mtns with primarilyVFR conditions. May see some
localized MVFR ceilings vcnty of slk mss after 06z, but
otherwise sct-bkn conditions expected. Upper trough passing to
our north is providing just enough forcing for ascent that a few
showers and tstms will remain possible through 03z or so this
evening. Main impacts will be south of slk with perhaps tsra at
rut 01-03z time frame as line of tstms across central ny moves
ewd. Brief heavy rainfall and isold cloud to ground lightning is
expected to be the main threat with any tstms. Generally
looking atVFR conditions areawide after 13z Saturday.


Saturday night:VFR. Chance shra.

Sunday:VFR. No sig wx.

Sunday night:VFR. No sig wx.

Monday:VFR. No sig wx.

Monday night:VFR. No sig wx.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
