341 pm edt Sun apr 23 2017

High pressure continues to keep the north country dry through
Monday night. Low pressure will move up along the eastern
seaboard bringing our next chance for showers Tuesday and
Wednesday, especially across our southeastern zones. A surface
cold front will bring the potential for more showers Thursday
night into Friday. Above normal temperatures are expected
throughout the week.

Near term /through Monday night/
As of 341 pm edt Sunday... Quiet weather for the near term as
high pressure remains over the area. Clouds will increase from
the north as cold front moves across southern quebec tonight.

Expect the north country will stay to the north but northerly
winds will settle over the region Monday. Combination of
northerly winds and gradually decreasing clouds on Monday will
lead to cooler MAX temperatures in the 50s to the north and
upper 50s to 60s areas south. Monday night will start with
mostly clear to partly cloudy skies but have clouds increasing
from the south late in the night ahead of a coastal low.

Temperatures will fall into the 30s Monday night.

Short term /Tuesday through Wednesday night/
As of 313 pm edt Sunday... Cool and damp conditions
expected... Along with some breezy winds along the western slopes
from danby to rutland to east middlebury to underhill. Still
anticipating several waves of light rain to move from south to north
across our fa with 1st round btwn 15z and 21z Tuesday and 2nd wave
impacting our eastern/central CWA on btwn 09z and 15z weds. Leading
5h vort and initial 850 to 500mb moisture quickly expands across our
region on Tuesday... While developing south/southeast low level winds
increase at 30 to 40 knots. The best winds associated with low level
925mb to 850mb SE jet stay to our east... But still thinking a few
gusts to 30 knots possible along the western slopes on Tuesday. The
jet orientation will impact QPF fields with slightly higher amounts
on SE upslope regions and less across the eastern cpv/western
slopes. General QPF will range between 0.05 and 0.25 for 1st round.

Next round of precip is associated with tightly compacted closed
mid/upper level cyclonic circulation and weak 1005mb low pres moving
along the eastern seaboard. Latest guidance continues to show a
sharp west to east precip gradient across our cwa... With minimal qpf
west and up to another 0.50 or so eastern/southeast sections on
weds. Based on low level jet orientation/placement and pws near 1.0"
this looks reasonable. Have mention likely to cat pops east and
tapered to chc west on weds with a sharp gradient in QPF fields.

Temps will also be depend upon clouds/precip with highs tues only in
the m/u 40s SE section to mid/upper 50s NW areas... And near 70f slv
to upper 50s ct river valley on weds. Lows hold mainly in the 40s on
Tuesday night with clouds/precip.

Long term /Thursday through Sunday/
As of 313 pm edt Sunday... Much above normal temps expected on
Thursday ahead of approaching cold front... With a band of
showers and embedded thunderstorms anticipated Thursday
aftn/night... Before cooler air arrives by next week. Mid/upper
level ridge builds ahead of developing s/w energy over the great
lakes on thurs... Placing our CWA in the warm sector. The slower
fropa arrival allows for 925mb temps to warm between 20-
22c... With 850mb temps near 15c on breezy south winds. Have gone
3 to 5 degrees above superblend with highs mainly m/u 70s
mountain valleys to lower 80s warmer valleys away from lake
champlain. GFS continues to show an axis of instability ahead of
short wave energy and cold front with CAPE values btwn 800-1200
j/kg. Still some uncertainty with timing of FROPA and
associated impacts. Cooler air eventually arrives late Friday
into Saturday... With a sharp boundary draped somewhere across
the NE conus/mid atlantic states next weekend. This will produce
a sharp divide in warm/unstable air to our south and
cooler/drier air to our north... With unsettled wx located near
the boundary. Plenty of uncertainty on exact placement of
boundary and potential impacts at days 6 and 7... So kept mention
of chc pops with temps very close to superblend values... Mainly

Aviation /20z Sunday through Friday/
Through 12z Monday...VFR conditions prevail with generally
light winds, except in the st lawrence valley with gusts
15-20kts in channeling effects. Clouds increase from the north
overnight, but generally expected to remainVFR cigs.

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.
