Synopsis
The forecast is beginning to sound like a broken record. High
pressure will be the dominant weather feature across the region
until at least the middle of next week with jose staying
southeast of new england. Dry weather and well above normal
temperatures are expected through much of the forecast period
with MAX temperatures approaching record values this weekend.

Early morning fog in primarily the usual favored locations is
also expected.

Near term through Friday
As of 224 pm edt Thursday... Models show the mid level high
pressure ridge will remain anchored over the great lakes with
the surface ridge extending along the saint lawrence. This puts
the btv area under predominantly light northerly winds, dry
weather and patchy morning fog in the usual valleys. Friday
temperatures will continue above normal with lows mainly in the
upper 40s and 50s and MAX readings mainly in the 70s.

Short term Friday night through Saturday night
As of 330 pm edt Thursday... High pressure and a strong cutoff high
aloft over the eastern great lakes will be in control for the
short term period and warmer temperatures.

With mainly clear skies, again looking for the usual river
valley fog Friday night with low temps ranging through the 40s
to lower 50s in the champlain and st. Lawrence valleys.

Saturday with 925 mb temps around 20c near btv and sunny skies
should bring high temps into the lower to mid 80s well above our
normal high of 68 in the burlington area.

Skies will be mainly clear Sat night and with the warm temps on
sat, the low temps Sat night will be warmer with lows in the
mid 50s to mid 60s, warmest near lake champlain.

Long term Sunday through Thursday
As of 330 pm edt Thursday... High pressure at the surface and
cutoff high aloft drifts slowly east Sunday into Monday and
perhaps tue. Anomalous heights and temperatures look to be
pushing us into possible record highs Sunday into Monday,
possibly Tue also. 925 mb temps rise to 22-23c Sun and are very
similar through tue. Highs through the period will be in the 80s
and wouldn't be surprised if someone hits 90. This will be up
to 20 degrees above normal for this time of year. Still no
precipitation and plenty of sunshine expected. With dew points
in the 60s it will definitely feel like a hot and humid summer
days. Ridge begins to weaken a bit Tuesday into Wednesday as a
weak cold front sags south from canada and weakens right over
northern areas but little chance in temperatures and a slight
chance of showers. Eventually an upper trough begins to move
toward the area on Wednesday night into Thursday with a better
chance of showers and cooler temps with readings back down into
the upper 60s and lower 70s by thu. Hurricane maria moving up
the east coast and is still forecast to remain south and east of
the area.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

It is not checked for accuracy either by anyone at L-36.com 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.
