708 am edt Thu aug 17 2017

High pressure over the area today will bring dry weather to the
area with high temperatures in the 70s to around 80. A warm
front will approach the region later tonight from the southwest
and enhance the potential for showers and a few thunderstorms
across the area... Especially over northern new york. Showers and
a few thunderstorms will exist over the entire area from time
to time... With the potential for some stronger storms over
northern new york late in the day on Friday. Showers and storms
will taper off Friday night... But scattered showers will exist
over the area on Saturday.

Near term through tonight
As of 707 am edt Thursday... Any fog will burn off quickly this
morning and area will just be dealing with mid and high level
clouds in the northwest flow aloft. Not expecting any
precipitation with highs in the 70s to around 80.

For tonight... A well defined warm front will move into the
region from the southwest and enhance the threat of showers and
embedded thunderstorms across northern new york after midnight.

Sharp dew point gradient clearly defines the front and with
noticeable warm air advection at 850 mb... Showers should be
likely with the front. Sharp gradient of showalter index values
moves into northern new york after midnight and this will
enhance the potential for elevated convection.

Short term Friday through Saturday
As of 503 am edt Thursday... Showers and a few thunderstorms
will be ongoing across much of the area Friday morning as warm
front lifts northeast across the region. Areal coverage of the
showers should decrease around midday as warm front lifts north
of the border. Composite analysis shows northern new york
getting into the warm sector and instability should develop with
highs in the 70s and dew points in the 65 to 70 degree range.

At the same time deep layer shear will be increasing over the
top of the instability and would expect the potential for
thunderstorms to develop in advance of the approaching cold
front. Will have to keep an eye on this situation because if
sufficient instability develops storms may get organized enough
to produce gusty winds... Hail... And heavy downpours. Mid level
lapse rates are not impressive and thus will need surface
heating to help drive the development of instability. Best
instability may be across central and southeast new york where
shear is a bit weaker. Precipitable water values in this area
will be around 2 inches as well. Clouds and showers over vermont
on Friday will keep highs in the upper 60s to mid 70s... But
over northern new york highs will be in the 70s to around 80.

Long term Saturday night through Wednesday
As of 503 am edt Thursday... Mainly dry weather is expected from
Saturday night through Tuesday morning. Cold air advection
continues Saturday night behind departing surface cold front
that crossed the area Friday night. Ridge of surface high
pressure centered over ohio river valley will build into our
region and remain through early Tuesday. An upper level trough
will push across our forecast area Saturday night and Sunday.

Looks like good eclipse viewing weather for Monday afternoon.

Southwest flow will develop Tuesday as surface ridge moves east
of the region, this flow will also advect some much warmer air
into the north country. A low pressure system will pass from the
northern great lakes area on Tuesday northeastward into central
quebec on Wednesday. Best chance for rain showers will be
Tuesday night into Wednesday with surface cold frontal passage.

Upper level trough will lag behind a bit, crossing our area
Thursday night into Friday. Overall the work week looks

Aviation 11z Thursday through Monday
Through 12z Friday... Overall looking atVFR conditions through
much of the period. However... After 04z conditions will trend
toward the MVFR category as a warm front moves into northern new
york. Showers will increase in areal coverage over northern new
york and the potential for some thunderstorms will also exist to
help lower ceilings and visibilities. The champlain valley may
see some showers and storms right toward the end of the period
along with the trend to MVFR conditions. Winds will generally be
under 10 knots through about 06z... Then increase from the
southeast during the remainder of the period.


Friday:VFR MVFR. Likely shra... Slight chance tsra.

Friday night:VFR. Likely shra... Slight chance tsra.

Saturday:VFR. Chance shra... Slight chance tsra.

Saturday night:VFR. Slight chance shra.

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.
