Building high pressure across ontario will bring several tranquil
days of weather to the north country. Light northwesterly winds
will allow low dewpoints to filter in the the region, and highs
will generally reach the low to mid 70s today and through the
weekend. The next chance for any widespread precipitation will
hold off until the middle of next week.

Near term through Saturday
As of 726 am edt Friday... A synoptically quiescent short-term
period is forecast as a broad surface anticyclone strengthens
north of the great lakes, and serves as our controlling weather
feature through the next 36 hours. Will continue to see daytime
nw winds 5-10 mph, and dry advection allowing dewpoints to fall
into the upper 40s to lower 50s. Once daytime heating mixing
begins, anticipate localized upslope cloudiness and patchy fog
will dissipate. Should see just a few fair weather cumulus
clouds dotting the higher terrain for the balance of the
late morning and afternoon hours. Some continued low-level caa
takes place today, with 850mb temperatures falling to between
+7c and +9c. Should support valley highs generally 71-75f,
except locally in the upper 70s with some downslope adiabatic
warming into the ct river valley.

A weak 700-500mb closed low develops to our south tonight into
Saturday, but with limited moisture available, not expecting
any significant weather associated with this feature. Continued
with mostly clear skies with lows tonight in the upper 40s to
lower 50s, except locally in the mid 50s in the immediate
champlain valley. Should see localized patchy fog 06-12z
Saturday in the normally favored valleys of central ERN vt and
the valleys within the northern adirondack region.

Surface anticyclone builds eastward across quebec on Saturday,
with a persistence forecast of mostly sunny conditions and highs
generally in the low-mid 70s across the north country.

Short term Saturday night through Sunday
As of 445 am edt Friday... Synoptically, we'll be in elongated
sw-ne longwave trof with a weak 500 mb cutoff across the area
aloft. At the surface... High pressure across eastern
quebec maine. Slight cool pool aloft would normally mean
instability but surface temperatures are not that warm and
lacking moisture with dewpoints in the l-m50s. Other than some
fair wx clouds... Keeping things dry and pleasant.

Long term Sunday night through Thursday
As of 445 am edt Friday... Weak trof, as mentioned in short term discussion.

Lifts NE thus some shortwave ridging for Monday-Monday night.

Devenorthern stream loping northern stream trof and cut-off
dropping from central canada into northern plains and eventually
just spinning across south- central canada but night-Tuesday
but rotating some energy and frontal boundary, mainly in the
wed-thu time frame. GFS canadian slightly faster with arrival of
boundary as its not influenced as much as potential tropical
system sliding well SE of new england as ECMWF is much stronger.

The general trend with surface high sliding east and return flow is
slow moderating trend through the week with chance of showers late
Tuesday (esp N ny) and then Wed with decreasing chances for thu
although still a threat of showers with next shortwave energy
attempting to rotate into area.

Seasonable temperatures in the mid 70s to lower 80s with dewpoints
largely in the 50s until Wed thu. Overnight lows in the 40s 50s sun-
mon ngts then warming into 50s 60s for the rest of the week.

Aviation 12z Friday through Tuesday
Through 12z Saturday... The daylight hours will feature skc-
few050-060 with fair weather cumulus dotting higher terrain
areas late this morning through the afternoon. Light NW winds
will increase to 7-10kt during the late morning through
afternoon hours... Becoming light and variable once again
tonight. Should see local lifr at mpv slk associated with
nocturnal fog development 06-12z Saturday.

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.
