1027 pm edt Mon mar 19 2018

High pressure remains well entrenched across the north country.

Persistent northwesterly flow will keep unseasonably cold and
dry weather over the north country through midweek. A coastal
low will strengthen Wednesday as it moves from the carolina
coast northeastward. The brunt of the impacts with this system
still look to be to our south and east, however we can't rule
out some light precipitation over areas of vermont Wednesday
and Thursday.

Near term through Tuesday night
As of 1027 pm edt Monday... No real changes needed at this time
with forecast on track. Clear skies and light winds starting to
allow temperatures to fall and lows of single digits above and
below zero should work out real nice.

Previous discussion... High pressure continues to build across
the north country this afternoon. Clear skies have been observed
across the region thanks to subsidence associated with the high
pressure and precipitable water values ranging from 0.05 inches
to 0.10 inches. Gusty winds will continue through the afternoon
hours as steep surface lapse rates have set up with
temperatures warming into the 20s and 850 mb temperatures still
in the -13c to -15c range. Once temperatures start cooling
around sunset, the boundary layer should quickly decouple and
gusty winds will quickly come to an end.

Temperatures tonight could be a little tricky as a diffuse
shortwave is slated to track across the region. Given
precipitable water values 0.10 inches or less, it's difficult to
imagine and precipitation will be squeezed out. However, there
is the potential for some cirrus to move over the region between
06z and 12z on Tuesday which may inhibit radiational cooling.

However, at this moment, the shortwave looks rather unimpressive
on both water vapor imagery and visible imagery which leans the
forecast away from any cloud cover during the overnight hours.

That being said, temperatures will once again be well below
normal tonight but should be a few degrees warmer across the
board than the past several night as the air mass continues to
modify. 850 mb temperatures continue to warm with models
progging temperatures warming from -15c this afternoon to -7c
by this time tomorrow. Temperatures in saranac lake will drop to
around -10f tonight while most other locations will remain in
the single digits to lower teens.

Wednesday will see temperatures warming into the upper 20s to
lower 30s as temperatures off the surface continue to warm.

Winds should be light as less mixing is expected with warming
elevated temperatures and the low level jet at 850 mb weakens.

Short term Wednesday through Wednesday night
As of 245 pm edt Monday... No real change in the forecast in
regards to the potential impact from another coastal low
developing off the carolina coast early Wednesday. While model
trends are hedging a tad further north, the consensus low track
remains south and east of the benchmark with the best deep layer
moisture and lift well southeast of the north country. Will
offer a slight increase in pops in the southeast corner of
windsor county Wednesday evening night but still only in the
chance category with perhaps a dusting to an inch of light snow
possible by Thursday morning. Elsewhere, partly cloudy skies
will persist through the period with only a slight chance of
light snow and or flurries with no accumulations expected at
this time. Temps will remain well below normal with highs only
in the upper 20s to low 30s and lows in the teens to mid 20s.

Long term Thursday through Monday
As of 245 pm edt Monday... Overall large scale pattern through
the end of the week and much of the weekend will feature a broad
upper trough over the northeast with bits of shortwave energy
moving generally south of the area as high pressure to our north
keeps the region dry. The result is mainly partly to mostly
cloudy skies, temps below normal in the 20s and 30s, and maybe a
few mountain snow showers. Heading into Sunday and Monday, an
amplifying upper ridge over the central CONUS will look to shift
over the northeast with some sunshine and closer to normal
temperatures possible.

Aviation 03z Tuesday through Saturday
Through 00z Wednesday...VFR conditions will persist through the
forecast period as high pressure remains over the area. Little
in the way of any cloud cover will exist as a result and winds
will generally be under 10 knots through the period.

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.
