Synopsis
Clouds cover will finally begin to diminish late this afternoon into
this evening with mostly clear skies residing through the overnight
hours. Some patchy dense fog is possible tonight but will likely be
limited to favorable locations within the green and adirondack
mountains. Sunday, Monday and Tuesday look to be very pleasant days
across the region with partly to mostly sunny skies and temperatures
in the 70s. The next chance of rain comes on Wednesday with a
weakening front moving toward the region. High pressure then looks
to redevelop across the region leading to another dry period of
weather for the second half of the upcoming week.

Near term through Sunday night
As of 306 pm edt Saturday... Clouds continue to be stubborn this
afternoon but it finally looks like there is an end in sight for the
abundant cloud cover. A strong subsidence inversion has trapped
moisture in the boundary layer so far today with the vertical extent
of these clouds just 1000 feet or so based off webcam and model
soundings. A shortwave approaching from the northeast has already
begun to break clouds out across the northeast kingdom as subsidence
behind the wave has helped to scour our the cloud cover. Once the
wave pushes through, we should see increasingly clearing skies
heading into the evening and overnight hours which will allow
temperatures to quickly fall especially given how we underperformed
on high temperatures today due to the cloud cover. With temperatures
falling quickly tonight, patchy dense fog is expected once again
across the favorable locations in the green and adirondack
mountains. Any fog that develops tonight will quickly mix out Sunday
morning with better heating as cloud cover should be much less
abundant.

High pressure will continue to remain dominant on Sunday with partly
to mostly clear skies allowing temperatures to warm back into the
70s across the region. Chances for rainfall are nearly zero percent
but there is a small chance for a little drizzle across southern
vermont during the late afternoon hours.

Short term Monday through Monday night
As of 306 pm edt Saturday... Surface high pressure will continue to
hold over the region with an upper low across the canadian maritimes
maintaining easterly flow over the region. This will advect a drier
air mass into the region. Another pleasant day is in store with
highs in the 70s. Winds begin to shift and come out of the south
overnight, so we begin a gradual warm up. Lows should be in the
upper 40s to mid 50s.

Long term Tuesday through Saturday
As of 306 pm edt Saturday... For Tuesday, surface high pressure will
slide offshore and upper ridge will crest over the region. Deep
layer southwesterly flow will initiate a gradual warm-up trend.

Tuesday should be just a few degrees warmer with valleys approaching
the low 80s. A north-south oriented front begins to move into the
region in the overnight hours Tuesday into Wednesday. Vorticity will
begin to get stretched ahead of the next trough as upper ridging
amplifies. Thus, the fronts motion will be sluggish and expect most
impacts on Wednesday, but there is some variability in model timing.

The front does have a few things going for it, like good height
falls, decent thermal gradients, and a high shear environment. On
the other hand, CAPE values look to be 250 j kg or less and low-
level convergence will be lacking without appreciable northwest
winds behind the front due to a secondary system right behind.

Additionally, the north country will not be located in a favorable
jet placement for upward motion. Overall, anticipate a line of
showers to track eastward throughout the day on Wednesday.

Timing of the front and clouds make the MAX temperature forecast for
Wednesday a challenge, but eastern vt will be warmest at least. The
front finally clears the area Thursday, but without any transition
to northwesterly flow, temperatures will not be much cooler behind
the front and there is also a piece of vorticity behind it and some
lingering instability, so the shower chances may linger a bit before
the stronger secondary system comes through. Models do not agree
when that takes place, so will keep a blend for now. High
temperatures should be near normal, but low temperatures will likely
be slightly above normal.

Aviation 19z Saturday through Thursday
Through 18z Sunday... MVFR conditions have lingered much longer
than expected today but it looks like some improvement from 2500
ft to 3500 ft has been noted over the past hours. This mix of
vfr and MVFR ceilings now looks to continue through the
afternoon hours into the evening hours when we see some breaks
in the cloud cover. Based on how quickly the cloud cover
dissipates this afternoon, temperatures could fall quickly
allowing kslk and kmpv to reach their crossover temperatures and
allow for some patchy dense fog to once again develop. The best
time frame for this will be 07z-12z with any fog quick to lift
on Sunday with less sky cover than today.

Outlook...

Sunday night:VFR. No sig wx.

Monday:VFR. No sig wx.

Monday night:VFR. No sig wx.

Tuesday:VFR. No sig wx.

Tuesday night:VFR. Slight chance shra.

Wednesday: mainlyVFR, with areas MVFR possible. Chance shra.

Wednesday night: mainlyVFR, with local ifr possible. Chance
shra.

Thursday: mainlyVFR, with local MVFR possible. Slight chance
shra.
