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
Dry and tranquil weather continues overnight. Rather cloudy
skies are anticipated Tuesday along with cooler temperatures. A
warm front will bring some showers to the region... Generally
Tuesday afternoon and evening. Mainly dry weather Wednesday
through Saturday. Moisture increases through the weekend with
the best chance of showers on Sunday. Much warmer Friday into
the weekend.

Near term until 6 am Tuesday morning
1010 pm update...

made some upward adjustments to wind speeds on coastal waters
for the next few hours per latest observations. Steamship
authority reported 15 to 17 kt winds in nantucket sound and buzz
bay has 15 kt. Otherwise forecast remains on track.

Satellite imagery shows cirrus overhead. Still expecting
temperatures to cool to 50 to 55 many areas before the cloud
shield thickens and prevents further outgoing radiation.

Mixed signals on how quickly the rain will move eastward.

Closest rain still on the oh pa border. But 400-500 mb winds
are forecast to increase to 50-55 kt from the west by tue
morning, which could allow it to spread rapidly eastward across
our region before noon, albeit light, falling from mid level
cloudiness. No change to precipitation forecast grids at this
time, however.

Short term 6 am Tuesday morning through Tuesday night
Tuesday and Tuesday night...

a rather cloudy day is on tap for Tuesday ahead of a warm
front. There appears to be enough forcing moisture along with a
modest low level jet for some showers Tuesday afternoon evening.

Not expecting a complete washout... But most locations should
see a period of wet weather during this time. There is even a
low risk for a rumble or two of thunder... Mainly near the south
coast with some marginal elevated instability. High temperatures
will be held in the upper 60s to around 70 in most locations
given the clouds along with the afternoon evening showers.

The bulk of the showers should come to an end Tuesday
evening... But a few will remain possible after midnight as a
weak cold front crosses the region. Clouds will probably hang
tough for most of the night and may see some fog develop given
ample low level moisture. This should hold overnight low
temperatures in the lower to middle 50s.

Long term Wednesday through Monday
Highlights...

* a spot shower lingers Wednesday
* cool Thursday but much warmer into the weekend
* risk of showers increases by Sunday
overview...

through the mid term, the N stream dominates, mainly in the
form of a longwave trof settling across the maritimes which is
linked to a baffin sea vortex. However, with the mean trof axis
to the w, central CONUS ridging will lead to rising heights and
generally cyclonic flow through the latter half of the week. It
is not until the tropical disturbance in the gulf of mexico gets
caught up with shortwave energy moving out of the pacific that
there is a transition for new england. These impacts,
particularly with a plume of tropical moisture, could yield a
wet latter half of memorial day weekend. Overall, enough
agreement between guidance to use a consensus blend for this
forecast update.

Wed...

cold front slows as it begins to parallel mid lvl flow.

However, soundings support rapid influx of drier air through the
column, reducing pwats to below 1.00in by mid day. Although
this does steepen lapse rates, the overall lack of moisture may
limit convective potential. Near nil QPF supports this thinking.

Still enough to warrant at least slight chance pops. Delayed
cold advection suggests highs should reach the mid 70s to around
80, especially as some clearing is observed.

Thu through sat...

mainly dry thanks to implied ridging through mid and upper lvl
height rises and sfc high pres as a response. Thu looks to be
the coolest day, but with h85 temps avg around +8c, it still
should yield low 70s across much of the region. Milder Fri and
sat with temps in the upper 70s and low 80s thanks to a gradual
increase in mid lvl temps. These are best observed inland
however, as weak pres gradient suggests local sea breezes at
area coastlines.

Sun into early next week...

echo previous forecasters concern and lack of overall
confidence as guidance widely diverges during this period. This
is not surprising, as models often struggle with complex
tropical interactions. At odds for new england, is a resurgence
in N stream forcing trof out of the arctic with its sfc
response, a n-s moving cold front front which makes temperatures
rather uncertain. From the S stream, is tropical moisture plume
with pwats potentially reaching near 2.00 inches just to the s.

If this dominates a period of wet and very unsettled conditions
are possible, keeping the front to the n. For now, will lean
most heavily on ensemble means for this period as it takes into
account the potential solutions. This will come into focus
better as the feature players, particularly the tropical wave
become better sampled.

Aviation 02z Tuesday through Saturday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ...

tonight... High confidence.

Vfr. Winds becoming light and variable.

Tuesday and Tuesday night... Moderate to high confidence. Mainly
vfr conditions into Tuesday afternoon. It probably will take
until evening especially along the coast for MVFR to localized
ifr ceilings and visibilities to arrive. These lower CIGS vsbys
will likely persist Tuesday night. Some showers expected
especially Tuesday afternoon and evening. A low risk for a
rumble or two of thunder mainly near the south coast tue
evening.

Kbos terminal... High confidence in taf. Still uncertainty though
in wind direction through 22z. Bos sea breeze kicked offshore as
of 19z... But still close enough where it needs to be watched for
another few hours.

Kbdl terminal... High confidence in taf.

Outlook Wednesday through Saturday ... Moderate confidence.

Wednesday: mainlyVFR.

Wednesday night:VFR. Breezy.

Thursday through Thursday night:VFR.

Friday through Friday night:VFR. Breezy.

Saturday: mainlyVFR, with areas MVFR possible. Chance shra.

Marine
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Tuesday night ...

tonight through Tuesday night... High confidence. Weak pressure
gradient will keep winds and seas below small craft advisory
thresholds through Tuesday night. Biggest concern for mariners
will be the potential for some fog developing Tuesday night
along with the low risk for a rumble or two of thunder across
our southern waters.

Outlook Wednesday through Saturday ... Moderate confidence.

Wednesday: winds less than 25 kt. Slight chance of rain
showers, patchy fog. Local visibility 1 to 3 nm.

Wednesday night: winds less than 25 kt. Seas locally
approaching 5 ft. Patchy fog. Local visibility 1 to 3 nm.

Thursday through Thursday night: winds less than 25 kt.

Friday: winds less than 25 kt. Local rough seas.

Friday night: winds less than 25 kt. Areas of rough seas.

Saturday: winds less than 25 kt. Areas of rough seas. Chance of
rain showers.
