Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Synopsis
High pressure will build in from the west tonight and will pass
out to sea south of new england Monday. Weak low pressure will
pass south of new england on Tuesday. A cold front will drop
south through the region Wednesday. Weak low pressure tracks
along the international border late Thursday into Friday. A
frontal system tracks into the area for the holiday weekend
bringing widespread showers.

Near term until 6 am Monday morning
Cold front crossing the cwa, and other than a few sprinkles in
srn nh thru about 4 pm, precip should be done. Will see a brief
surge of W winds into early evening, with gusts to around 20 mph
or so. Will still see a fair amount of clouds thru sunset, but
certainly partly sunny in many spots, with rapid clearing
expected after sunset. Winds will diminish over the first part
of the evening, and should become light, which should set up a
good rad cooling night, with lows dropping into the upper 30s in
the sheltered mountain valleys, and into 40s to low 50s
elsewhere.

Short term 6 am Monday morning through Monday night
High pressure builds in from the west Monday and crosses the
region Monday night. This will allow for unlimited sun, and mild
conditions. Highs will be in the 70s, but may be a little
cooler in the mountains. Will get close to meteorological red
flag conditions on Monday, and fire wx watch has been issued.

See fire ws discussion below for more.

Weak SW flow on the boundary lyr should allow for slightly
warmer temps than Sunday night, but some of the usual spots
will decouple, so lows will generally run from around 40 in the
north to the low 50s in the south. Cirrus may start to move in
late, but the first part of the night should be mainly clear.

Long term Tuesday through Sunday
The deterministic model solutions are now in decent agreement on
the long wave pattern through the upcoming holiday weekend. We
begin the period with a weak shortwave impulse racing eastward
from the great lakes on Tuesday. Meanwhile... Shortwave energy
will ride over the top of a building western canadian ridge and quickly
carve out another upper trough across the great lakes and new
england for the second half of the new work week. This trough
shears out by the start of the holiday weekend with ridging in the
interim for Saturday. By Sunday... Models show troughing across
the eastern half of the CONUS with various degrees of phasing
between northern and southern stream energy. At this juncture... It
looks like a dry start to the upcoming holiday weekend... Then increasingly
unsettled for the second half of the long weekend. In the
dailies... A shortwave impulse and weak surface reflection will
cross the area late Tuesday early Wednesday with clouds and
scattered showers. Another weak moisture starved boundary drops
south across the area late Wednesday. High pressure briefly
follows for Thursday. Another weak moisture starved boundary drops
south across the area Thursday night early Friday. High pressure
and drier air briefly follows late Friday into Saturday. A slow-
moving frontal system then moves eastward into the forecast area
for the remainder of the holiday weekend... With clouds and showers
gradually increasing in coverage.

Aviation 20z Sunday through Friday
Short term... MainlyVFR tonight thru Monday night. Some vly fog
expected at kleb khie toward daybreak Monday.

Long term...

tue - wed... Sct MVFR in -shra.

Fri... Sct MVFR in -shra.

Marine
Short term... Will leave the scas up for now as seas still
coming around 5 ft, but will likely see conds drop below sca
criteria in the next few hours. Otherwise, expecting sub-sca
conds into Monday night.

Long term...

tue pm - Wed am... Sca's are psb... Especially outside the bays.

Thu pm - Fri am... Sca's are psb... Especially outside the bays.

Fire weather
Rh will fall to 25-30 percent Monday afternoon, with winds
gusting to 20 mph, maybe as high as 25 mph in the north. This
will just meet meteorological red flags conditions. After
consulting with state forest rangers, thinking is that given the
wind and full Sun expected tomorrow, as well as temps in the
70s, this will dry things out quickly, so fire wx watch has been
issued for the entire CWA for Monday aft into early eve.

Gyx watches warnings advisories
Me... Fire weather watch from Monday afternoon through Monday
evening for mez007>009-012>014-018>028.

evening for nhz001>015.

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.
