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 weak, broad area of high pressure will bring in drier
conditions this morning. Low pressure from the great lakes
will push across the region, bringing showers and a few
thunderstorms this 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 pm this evening
1020 am update...

still lots of stratus across sne this morning but there are
breaks developing. While clouds will dominate for much of the
day per abundant low level rh, there will be some breaks of
sunshine as well. Stratus may be tough to erode along the
immediate south coast and especially the islands with fog
redeveloping over the islands by late afternoon. The clouds
should hold temps in the 70s, possibly near 80 in the ct and
merrimack valleys.

The main concern for this afternoon is the thunderstorm risk as
mid level trough approaches from the west. Various hi-res
guidance sources do suggest at least sct storms will develop
mid late afternoon. Some mid level cooling later this afternoon
combined with dewpoints rising into the mid upper 60s will
contribute to capes around 1000 j kg. Mid level lapse rates are
not favorable but there should be enough instability combined
with approaching trough for sct t-storms to develop, mainly
interior where instability axis sets up. 0-6km shear 35-40 kt so
can't rule out a few strong to severe storms, but weak mid
level lapse rates will likely limit areal coverage.

Short term 6 pm this evening through 6 am Monday
The weak low and associated front will push across the region
tonight. Precip should taper off during the evening across the
ct valley, then around or after midnight further e. Some
downpours will still be possible through around 06z with the
higher pwats. Winds will shift to n-nw as the front passes.

Temps will fall back to the upper 50s to mid 60s as clouds
linger through most of the night especially across central and
eastern areas.

Long term Monday through Saturday
Highlights...

* seasonable temperatures through Thu with chance of showers
Monday and Wed night thu
* prolonged heat wave may begin next weekend
Monday...

24 00z guidance has all come into line swinging an anomalously
strong cold pool across our region during this time. Expected
wind directions still favor some surface convergence somewhere
across eastern ma and ri. The combination of these two features
should be enough to trigger some showers, and perhaps a few
thunderstorms during the afternoon, too. Below normal
temperatures anticipated.

Drying out Monday night, with decent radiational cooling
conditions developing as high pressure starts to arrive.

Tuesday...

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

Wednesday...

mainly dry weather expected, with an increasing risk for showers
late in the day across far western ma. Near normal temperatures
Wednesday night and Thursday...

a cold front moves into southern new england with above normal
humidity. Showers and a few thunderstorms are likely, with some
potentially heavy downpours. This front exits our region
sometime Thu night, bringing an end to the threat of
precipitation.

Friday and Saturday...

the upper level pattern changes significantly, with a building
mid level ridge along the eastern seaboard. Ensembles continue
to indicate well above normal temperatures at 925 mb and 850 mb.

This should mean well above normal temperatures at the surface
as well, except for perhaps the CAPE and islands where SW flow
off the water will keep temperatures lower. Expecting hot and
humid conditions during this time, perhaps continuing into early
next week. Heat advisories will likely be needed, especially by
Saturday.

Aviation 14z Sunday through Thursday
Forecaster confidence levels...

1020 am update...

ifr MVFR CIGS should lift toVFR this afternoon, but lower
conditions lingering along the immediate south coast and
islands. Sct t-storms developing in the interior mid late
afternoon with brief lower conditions.

Tonight...

any showers thunderstorms end early across W and central, then
by around 06z e. Any MVFR-ifr conditions will improve toVFR
overnight. Winds shift to n-sw overnight bringing drier air.

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

southwest winds during the day will remain light. Seas will
generally be below 5 feet. Vsbys lowering by late afternoon over
south coastal waters as fog redevelops.

Tonight...

winds less than 25 knots, and seas 4 ft or less. Some lingering
5 foot seas may linger on the southern outer waters. A cold
front will move south across the waters around midnight or so,
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: low risk for small craft advisory winds with gusts up
to 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.
