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 warm front will slowly shift north, bringing showers and
possibly a few thunderstorms overnight. Low pressure from the
great lakes moves across new england Sunday and will bring
showers and a few thunderstorms, especially during the
afternoon and evening. Scattered showers and thunderstorms
are possible Monday. Sunny and seasonable weather Tuesday into
Wednesday with high pressure in control. After some showers and
thunderstorms Wednesday night and Thursday, summer heat and
humidity will return Friday and Saturday as this high moves east
of the region.

Near term until 6 am Sunday morning
1030 pm update...

areas of low clouds, drizzle and fog continue across most of the
region. Spotty showers are crossing the region, moving e-ne,
along with a couple of bands of showers scattered thunderstorms
moving toward the S coast as seen on latest NE regional 88d
radar imagery. Areas of dense fog lie across portions of the
coastal waters as well as CAPE cod, along with spotty dense fog
across the worcester hills.

May see scattered showers and an isolated thunderstorm or two
cross S coastal areas over the next few hours. Will see variable
conditions as it appears some patchy dry spots are also moving
across the region, with briefly improving conditions. While the
showers are spotty, will likely see areas of drizzle will
continue especially across the coastal plain with dewpoints in
the upper 50s to mid 60s, not far from the air temps.

Have updated to bring near term conditions current and
incorporated trends into the overnight forecast.

Short term 6 am Sunday morning through Sunday night
Another shortwave moves through the flow Sunday and Sunday
night. The shortwave will generate a wave on the warm front,
which then draws the warm front back to the south as a cold
front later in the day and early night. The upper temp field
features a small amount of cold advection, which will cause some
destabilization. The wind and divergence fields are enough to
generate adequate lift Sunday afternoon and early night.

With the high pw values, a few heavy downpours are possible. The
spc href ensemble shows a 70-90 percent chance CAPE reaching
1000 joules kg in western ct and western ma Sunday late
aftn evening. We will mention a chance of strong gusts and
locally heavy downpours.

We will forecast showers and scattered thunder, with the
favored time from midday through evening. Temps in the mixed
layer reach an equiv of 10-12c, so with appreciable heating we
should reach the 70s with the interior in the upper 70s low 80s.

Dew points will be in the 60s, so expect a warm muggy day. Min
temps Sunday night will be near the dew points, in the 60s.

Long term Monday through Saturday
Highlights...

* seasonable temperatures through thurs.With chance of showers
Monday and wed. Night thurs.

* prolonged heat wave may begin next weekend...

Monday...

a vigorous shortwave and cold pool aloft dives southward and
into northern ma on Monday. 500 mb temperatures drop to -22c
which leads to total totals indices on the order of 50-53 Monday
afternoon. Winds are forecast to be from the northeast in
eastern ma and ri but from the northwest in western ma and
northern ct, leading to some low level convergence. Despite
temperatures only reaching the low to mid 70s, the cold air
aloft will lead to enough instability to create a chance of
showers and thunderstorms during the afternoon and early evening
hours. The best chances will be in central and eastern ma.

Tuesday...

sunny and pleasant with surface high pressure centered just south
of the region. Low humidity, with dewpoints in the mid and upper
40s. Clear tue. Night with pleasant sleeping conditions with
lows in the 50s.

Wednesday...

wed. Will be a mainly sunny day but clouds will increase mainly in
western areas as the afternoon progresses. This is due to a
significant influx of moisture aloft spreading in from west to
east. K indices increase from single digits to near 30 by wed.

Evening. Highs mainly 80 to 85.

Wednesday night and Thursday...

a cold front moves into the region with increasing moisture and
precipitable waters approaching 1.7 to 2.0 inches. Showers and a
few thunderstorms are likely, with some potentially heavy
downpours. The front exits the region thu. Night, bringing an
end to the precipitation.

Friday and Saturday...

the upper level pattern changes significantly, with a closed
ridge of high pressure becoming centered just south of our
region... And strengthening through the weekend and into the
following week, for that matter. High pressure at the surface
slides off to our southeast. This will lead to mainly sunny
skies, but high heat and humidity. Have used wpc guidance
temperatures, which were on the upper end of guidance values,
for this time period. Forecasting upper 80s and lower 90s Friday
and lower to mid 90s on Saturday, with dewpoints rising to near
70 by Saturday. Heat advisories will likely be needed,
especially by Saturday.

Although the forecast does not go beyond Saturday, there are
signals that this could be the beginnings of a prolonged heat
wave, with the heat and humidity possibly lasting well into the
first week of july.

Aviation 03z Sunday through Thursday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

and an isolated tsra or two mainly near and S of the mass pike.

Will see local vsby improvement just away from the S coast as
well as across the route 2 area through 05z or so, but should
lower again through daybreak.

Sunday...

ifr CIGS vsbys early, but improving toVFR during the morning.

Low conditions may continue through the morning on the islands,
but should improve toVFR around midday. Low pressure moves
across new england during the day, swinging a cold front through
the region during the afternoon evening. This will bring showers
and a few thunderstorms. Overall conditions should beVFR from
midday through evening, but with brief lowering to MVFR during
showers tstms.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Sunday night ... High confidence.

1030 pm update...

overnight...

expect light N winds across the eastern waters which will shift
to SW toward daybreak, while remaining SW on the southern waters
overnight. Seas will remain close to 5 feet across the southern
outer waters. Scattered showers and a few thunderstorms will
pass across the southern waters to E of CAPE cod through around
06z-07z, then move off to the east. Areas of fog and drizzle
with visibilities generally 1 to 3 miles, except areas of
dense fog, with visibility at or below 1 4 mile, from CAPE cod
to the southern waters which may begin to improve around
daybreak.

Sunday...

winds shift out of the southwest during the day but remain
light. Seas will mostly be less than 5 feet, except for seas at
5 feet on the outer part of the southern outer waters. Much of
this is from a 5-6 foot swell south of our waters. Visibility 1
to 3 miles early in fog, improving by midday. Expect a chance
of showers and scattered thunderstorms, mostly during the
afternoon.

Sunday night...

winds less than 25 knots, and seas mostly less than 5 feet.

Some lingering 5 foot seas in the southern part of our southern
waters. A cold front will move south across the waters early in
the night, and may continue to generate showers and a chance of
a thunderstorm. This should move out to sea overnight.

Outlook Monday through Thursday ... Moderate confidence.

Monday: winds less than 25 kt. Areas of seas approaching 5 ft.

Slight chance of rain showers.

Monday night: winds less than 25 kt. Areas of seas approaching
5 ft.

Tuesday: winds less than 25 kt. Seas below 5 ft.

Tuesday night through Wednesday: winds less than 25 kt. Seas
