920 am edt Tue mar 20 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 southern areas of vermont
late Wednesday into Thursday.

Near term through Wednesday
As of 913 am edt Tuesday... Made minor changes to the temp grids
this morning to account for the current temperature trend and to
bump MAX temps up 1-3 degrees across the north country. With
another sunny day on tap and 850 mb temperatures expected to
warm, it now looks like a few locations may briefly warm above
freezing late this afternoon. Nevertheless, well below normal
temperatures (8 to 13 degrees below normal) are expected once
again. Have a wonderful start of spring at 12:15 pm.

Previous discussion... High pressure will remain lodged across
the north country today, resulting in another day of sunshine
and cool temperatures. Winds will be fairly light and with highs
in the upper 20s to lower 30s, it should be an overall pleasant

For tonight and Wednesday... Low pressure will develop off the mid
atlantic coast and slide east-northeast. Precipitation associated
with this system will spread north and east as well, moving into
southern new england during the day Wednesday. The high pressure
will remain wedged over our region, keeping the low shunted to the
south and east of the benchmark. Note that the NAM and SREF are more
aggressive with bringing the precip shield north, while the gfs,
ecmwf, and cmc pretty much keep our forecast area dry. Current
thinking is to lean closer to the drier solutions as precip will
likely have a hard time making much northward progress given the dry
airmass that currently resides across the north country. However,
don't want to totally discount the higher-res models, so have gone
with a model blend. This results in a chance of snow late Wednesday
afternoon for areas along south of a quechee to rutland line. Little
to no daytime snow accumulation is expected. After morning lows
mainly in the 5-15 degree range, Wednesday's highs will top out in
the upper 20s to mid 30s.

Short term Wednesday night through Thursday
As of 352 am edt Tuesday... On Wednesday night coastal low
pressure system will be tracking just outside the benchmark off
the coast of CAPE cod. All of the stronger forcing and deeper
moisture will be southeast of our region. Do expected some light
snow for windsor county Wednesday night, have mentioned up to
about two inches of snowfall. On Thursday as the low lifts north
and eastward, will have some wrap around light snow showers in
the northeast kingdom of vermont. Accumulations will be light.

Temperatures will be near seasonal normals Wednesday night with
plenty of clouds across the region, then cooler than seasonal
normals on Thursday.

Long term Thursday night through Monday
As of 352 am edt Tuesday... No big changes for the long term
portion of the forecast from Thursday night through Tuesday.

Still mainly just an upper trough over the area, mainly
resulting in a bunch of clouds and some colder than normal
temperatures continuing. Will have occasional bits of shortwave
energy pass through the progressive flow and a few mountain snow
showers will be possible. Temperatures will start out colder
than seasonal normals, trending back towards normal headed into
next weekend.

Aviation 13z Tuesday through Saturday
Through 12z 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 tonight. High clouds
will begin to move in across southern vermont late tonight as
low pressure moves off the east coast, but no precipitation is

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 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.
