Synopsis
Strong high pressure will continue to provide fair and very
warm, record setting temperatures to the region through
Wednesday. A cold front will cross the area Wednesday night
along with a chance of showers. Much cooler, more seasonable
weather is expected behind this front to round out the week.

Near term through Tuesday
As of 317 pm edt Monday...

more record temperatures have been set again today as deep
layer, anomalously strong high pressure remains anchored across
the northeast. This high will remain draped across the area into
Tuesday night with a persistence forecast being offered over
the next 36 hours. A few congested cumulus have developed across
the southern higher terrain of the greens and the white
mountains of nh this afternoon where weakly forced terrain flows
have produced just enough upward momentum to produce a few
stray showers. Expect this isolated activity to end by sunset
leaving another mainly clear night outside the typical fog-prone
areas of the dacks eastern vt and possibly the slv. Lows
tonight very similar to last night, mainly ranging from 55 to 65
with customary variability. Winds light to calm.

By tomorrow another rinse and repeat day is expected with mainly
sunny skies outside a few passing thin high clouds. 850 925 my
temperatures are perhaps a half degree cooler than today, but
should have little impact to high temperatures with values once
again topping out in the mid 80s across elevated terrain to the
lower 90s in the deeper valleys. See climate section below for
specific records. Then clear to partly cloudy by Tuesday night
under light winds and patchy fog in favored locales. Lows again
mainly in the 55 to 65 range.

Short term Tuesday night through Wednesday
As of 317 pm edt Monday... Its much of the same story for Tuesday
evening as the ridge will still be in place. High heat during
the day Tuesday and high dewpoints during the afternoon will
lead to fog overnight. General feeling is that there will be
some dense fog in the sheltered valley locations with some
patches of fog elsewhere. Overnight lows will be in the 60s
again, which is more indicative of our normals highs this time
of year.

The airmass will be slightly changing into Wednesday as the
ridge finally breaks down however not much changes in the thermal
profile until late. 925mb temps still support temps in the upper
80s with 90's in the valleys. I wasn't as bullish on that as
we should start to build in some cloud cover that would
insulate the north country from peak heating. Even so the
forecast of mid to upper 80s would still set or tie records at
btv mpv mss 1v4. With records possible i'll hold on to the
previous discussion highlighting heat hazards below:
while these temps are considered sub advisory(<95 f), they are
not to be taken lightly especially given the time of year. Based
on the forecast and current records, its expected that records
will fall at all sites by 3-5 degrees. Prolonged exposure
outside combined with strenuous activity can lead to heat
related injuries. Please take caution, stay hydrated and take
frequent breaks during any outdoor activities. This will be the
fourth consecutive day with 90+ degree heat indexes during the
afternoon.

Long term Wednesday night through Monday
Wednesday night is when we should finally start to see some
reprieve from the heat. A mid level short wave will finally move
into the north country but the moisture isn't very strong. I've
trended the forecast back another 3-6 hours as guidance seemed
overdone on the precip threat during the late afternoon
Wednesday.

A weak cold front will swing through during the overnight hours
Wednesday and bring scattered showers. Given the overnight
timing I dont feel there will be any thunder threat so i've
opted to continue with no mention of thunder. Behind the front
we get into cold air advection and see temps return to near
normal with highs in the 60s and lows in the 40s.

Late in the week heading into the weekend guidance is starting
to bring a shortwave trough into the region so i've mentioned
slight chance for pops but I dont have high confidence in
timing of the isolated to scattered showers.

Aviation 19z Monday through Saturday
Through 18z Tuesday...VFR conditions through about 06z before
fog returns at several sites through the overnight period.

Little in the way of cloud cover through the period, diurnally
driven few-sct cumulus clouds, but brief periods of lifr to
vlifr ceilings associated with the fog... Especially at kslk and
kmpv. Winds will be less than 10 knots through the period.

Outlook...

Monday night:VFR. Patchy fg.

Tuesday:VFR. No sig wx.

Tuesday night:VFR. No sig wx.

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.
