737 am edt Sat sep 23 2017

High pressure continues to dominate through the weekend into next
week while the remnants of post tropical cyclone jose remain
southeast of new england. Quiet and dry conditions continue through
the weekend with some fog in the favored locations in the early
mornings. Temperatures will continue to be well above seasonal
average with potential record highs over this weekend.

Near term through Sunday
As of 356 am edt Saturday... Stop me if you've heard this one before.

High pressure is still entrenched over the north country. This
is keeping the remnants of post tropical cyclone jose to the
southeast of the new england and is not a factor for us right
now. Much like last night, fog and low stratus is not widespread
this morning, but areas do remain and will be gone shortly
after sunrise. Saturday will feel less like the beginning of
fall and more mid summer like 925mb temps of 21-22c will see
valley locations pushing mid to upper 80s with sunny skies. This
leads into Saturday night which will feel rather uncomfortable
as low temperatures will remain in the 60s, to go along with dew
points also in the 60s leading a warm and muggy evening the

Sunday brings the next round of fair conditions and heat as 925mb
temps rise to 23-24c leading to temps in the upper 80s with a few
locations possibly reaching 90. Seeing some daily high temperature
records fall is well within the realm of possibility.

Short term Sunday night through Monday
As of 356 am edt Saturday... Little change to the weather is expected
for Sunday night and Monday with the upper ridge remaining in
place over the area. Dew points will be on the high side so it
will be another night of above normal temperatures and on Monday
we are still looking at highs well into the 80s. The higher dew
points on Monday will push heat index values into the lower 90s
across the larger valleys (saint lawrence and champlain).

Long term Monday night through Friday
As of 356 am edt Saturday... Forecast remains on track with a general
flattening of the upper ridge Monday night through Wednesday.

Warm temperatures aloft will continue to result in temperatures
about 20 degrees above normal on Tuesday and about 15 degrees
above normal on Wednesday. The flow aloft becomes more west and
southwest by Wednesday and this may result in an increased
potential for isolated to scattered showers in the afternoon. A
greater likelihood of showers is expected for Thursday as an
upper level trough of low pressure moves into the region. Once
the trough passes to the east on Friday cooler and drier weather
is expected. High temperatures will return to seasonal normals.

Aviation 12z Saturday through Wednesday
Through 12z Sunday... PredominantlyVFR conditions expected
through the TAF period with mostly clear skies. The possible
exception might be some overnight fog and MVFR conditions at
kmpv kslk. Light winds less than 10 knots are expected today.

There are five sources. 1) Documents and manuals from a variety of sources. These have not been checked for accuracy and in many cases have not even been read by anyone associated with I have no idea of they are useful or accurate, I leave that to the reader. 2) Articles others have written and submitted. If you have questions on these, please contact the author. 3) Articles that represent my personal opinions. These are intended to promote thought and for entertainment. 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.
