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
A cold front across northern maine this morning will push off
the downeast coast later this afternoon. High pressure will
build into the region tonight with frost expected from the
katahdin region north. A warm front approaching from the west
may bring a late day shower Thursday in the saint john valley.

Much warmer Friday as the warm front lifts north of the region.

Near term through tonight
9:15 am update... Showers are pushing into the north and should
be moving south across the area through the late morning and
midday hours. Adjusted pops a bit to sharpen the leading edge of
the rain. Also raised temps a bit right ahead of the front
across the north where temps are already in the upper 50s in
many areas.

Original discussion...

a cold front will push into the CWA this morning, and indeed,
fve is already showing a light NW wind. This front will continue
to push south through the day, and push off the coast by later
this afternoon. Some marginal instability is expected to develop
this afternoon ahead of the front - likely too late for any
thunder over much of the north, but central and southern parts
of the CWA certainly stand a good chance of seeing some
thunderstorms. Widespread CAPE of 500-1000 j kg expected in
these areas, and between cold air aloft (-20c around 500mb) and
increasing shear, at least some small hail and gusty winds can't
be ruled out. The greatest risk appears to be between noon and
5pm. Model forecasts of the sherb parameter, geared toward such
high shear low CAPE situations, approach and locally exceed
1.0 in most models, which is the threshold for considering an
increasing possibility of strong to severe storms. However,
given the conditional nature of the threat, stronger wording was
left out at this time.

As the front pushes south, a fairly quick drying is expected
behind the front. As high pressure settles over the area this
evening and tonight, clearing skies and lower dewpoints will
allow temps to quickly drop. Frost advisory is up for eastern
aroostook and northern penobscot, with temps dropping into the
low to mid 30s. An hour or two of below freezing temps are
possible in valley locations in these zones, but confidence
wasn't there for 3 or more hours of sub-freezing temps, so no
freeze watch or warning was issued.

Short term Thursday through Friday
Thursday will start clear and in some spots in the north
frosty early in the morning. High pressure across the region
will move south of new england during the afternoon as a warm
front approaches from the west. Clouds will increase during the
afternoon with the chance of a late day shower across the
western saint john valley and north woods. A band of showers
will likely move across northern sections of the CWA Thu night,
and perhaps into Fri morning. The warm front is expected to
stall out somewhere across or just north of far northern maine
fri with a very warm air mass across the region. Most of the
models have 925h temps into the m u teens (c) in the saint john
valley with low 20s (c) downeast. Highs were raised a bit
across interior downeast, and there is the potential that highs
could reach the upper 80s to near 90f. A fast moving
disturbance may touch off late day showers and possible
thunderstorms, with the best chance over the central highlands.

Temperatures will be tricky and depend on the final position of
the front and the amount of cloud cover; with the potential for
a large spread from the far north to interior downeast.

Long term Friday night through Tuesday
A cold front will push south across the area Fri night as low pres
over northern maine Fri eve moves south and east of the region
by Sat morning. The models do differ on the placement of the low
and where the best chance of showers rain will be Fri night.

Would expect that the best chance will likely shift further
south across the CWA with time Fri night, but the details remain
uncertain. Sat will be much cooler and drier with some Sun in
the north, but depending on where the front ends up there could
be a continued chance of showers downeast Saturday; but the
latest runs of the gfs, ecmwf, and canadian push drier air south
into the downeast region and forecast confidence is increasing
that it will be mainly dry downeast. There is more uncertainty
during the second half of the weekend. The GFS & canadian push
the front offshore with dry weather, while the ECMWF hangs the
front up across the area with the chance of showers. Another
wave moving in from the west may bring another chance of showers
later Mon into Tue with a cold frontal passage, but details
such as any convective potential remain uncertain.

Aviation 13z Wednesday through Sunday
Near term: largelyVFR conditions this morning. But as shower
coverage increases from north to south through the day, MVFR
cigs and locally MVFR vis will be possible in and around shower
activity. Afternoon thunderstorms possible from khul through
kbhb, which could create localized increased turbulence and
other hazards. A quick return toVFR conditions expected at all
sites from north to south later this afternoon into the evening.

Short term:VFR Thu with the chance of MVFR ceilings at kfve
toward 00z Fri as showers move into the area from the west.

MVFR ceilings are possible at times Thu night into Fri morning
at the northern terminals in showers withVFR expected
downeast. PredominatelyVFR Fri through sun, but brief periods
of MVFR are possible, especially at the downeast terminals fri
night into early Sat in showers. The forecast is more uncertain
for sun, but at this time would favorVFR; although can't rule
out MVFR if there are some showers around.

Marine
Near term: light to moderate s-sw'ly winds continue this morning
and early afternoon, with seas generally 2-3 feet in outer
waters. As the front pushes offshore later today, winds will
shift nw-n'ly and freshen some, with gusts to 20kts possible
overnight. Winds will then decrease late Wed night as high
pressure pushes toward the coast.

Short term: light wind and seas only 1 to 2 feet Thu morning. A west
to southwest flow begins to increase late in the day and continues
into fri. The seas will gradually build, and it is likely a
small craft advisory will be needed by Thu night and into Friday
for seas, although it is more marginal for wind with gusts 20
to 25 knots.
