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 slowly push offshore overnight. A few showers
may approach southern areas toward daybreak. Scattered showers
and a few thunderstorms are expected at times this weekend, but
it is uncertain if any activity will linger into Monday. Mainly
dry weather with seasonable temperatures anticipated Tuesday and
Wednesday with a ridge of high pressure in control. Summer heat
and humidity should return by the end of next week as this high
moves east of the region.

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

high pressure ridge remains across the region at 02z with light
s-se winds in place. Temps were running in the lower-mid 60s
across most areas, with some readings down to the upper 50s
across portions of SE mass into ri.

Ne regional 88d radar imagery showing some spotty showers
working n-ne from central nj into SW ct and the nyc metro area.

Not seeing much reaching the ground, however, as t TD spreads
on the order of 10 to 15 degrees, lowering to around 5 degrees
across portions of western long island into N nj where winds
were mainly light easterly. With the onshore winds in place,
will see the dewpoint depressions slowly lower through the
remainder of the night as the ridge pushes offshore.

With this in mind, have brought in slight chance pops across the
mid and lower ct valley SE to the S mass coast by around 09z or
so, a bit faster than previous forecast timing.

Remainder of near term forecast in good shape, but did update to
bring conditions current.

Previous discussion...

the center of high pressure will continue to gradually slide
east of our region. Mainly expect increasing thickening
cloudiness across our area overnight with dry weather
prevailing. May see a few spot showers arrive near
daybreak... But there is initially some dry air to overcome. Low
temperatures will mainly be in the middle to upper 50s.

Also, we did update Saturday to include categorical pops and
the potential for localized heavy rainfall. While the entire day
will not be a washout... Most locations should see a period of
two of rainfall with isolated t-storms possible.

Short term 6 am Saturday morning through Saturday night
Saturday...

a warm front lifts ne-ward during the day, and may reach the south
coast of new england around 00z. Increasing moisture is
expected throughout southern new england, with precipitable
water increasing to 1.5 inches or higher. The approach of the
front will provide lift, allowing for the development of showers
across our area. Planning on going with likely pops. While it
doesn't look to be a washout for the full day, hi-res guidance
is in agreement on areas of showers moving thru the region.

Model thermal profiles show a low level inversion which makes sense
given warm front to the s, and an onshore E wind providing a cooler
marine influence near the surface. However some elevated instability
is anticipated, which should yield isolated thunderstorms and
the potential for brief locally heavy rainfall. Plan to go with
likely pops and considerable cloudiness. High temps will be on
the low side, only reaching into the 60s. A few spots might
reach 70.

Saturday night...

warm front lingers in our vicinity Sat night, accompanied by a 30-40
kt low level jet. This will continue to provide a lifting mechanism
for showers. Precipitable water values remain at or above 1.5
inches, so brief locally heavy rainfall is possible. Model
soundings showing continued elevated instability. Will continue
with likely pops, with isolated thunderstorms. Best chance for
thunder is probably along south coastal ma ri, closer to the low
level jet. Areas of fog developing.

Long term Sunday through Friday
Highlights...

* warmer with scattered showers and t-storms on Sunday
* mainly dry seasonable temps with comfortable humidity Tue and wed
* summer heat humidity should return by the end of next week
details...

Sunday...

the warm front will lift north of most locations Sunday
morning... Allowing a warmer and more humid airmass to move into the
region. High temps should reach into the upper 70s and lower 80s
despite potential for a fair amount of clouds. We may see a period
of partial sunshine though and if that does occur a few middle 80s
would be possible.

The main concern will be Sun afternoon evening when a pre-frontal
trough cold front approach from the west. There probably should be
enough instability for scattered showers and a few thunderstorms
during that time. If we can muster 1000 j kg of mlcape... Which is
dependent on solar insolation and amount of low level moisture
return a few strong thunderstorms would be possible. 0 to 6 km shear
is on the order of 30 to 40 knots... But mid level lapse rates are
weak and we will not have the anomalous environment that we saw last
Monday. Nonetheless... A few strong thunderstorms with gusty winds
and heavy rainfall are possible if enough instability can be
realized.

Monday...

a vigorous shortwave cold pool aloft will drop southeast into the
northeast on Monday. The GFS is most aggressive showing the
anomalous cold pool dropping furthest south into our region with
500t dropping below -20c. This scenario would likely produce
scattered showers and thunderstorms along with some hail given such
cold temperatures aloft. While this solution is possible, appears
to be a low probability at this time given the rest of the guidance
is further north and east with the cold pool... Resulting in mainly
dry weather. Therefore... Will just include some low pops for now
and see how the models trend over the next 24 hours.

Tuesday and Wednesday...

mainly dry and pleasant early summer weather with a ridge of high
pressure in control. High temperatures will mainly be in the upper
70s to the middle 80s along with comfortable humidity levels.

Thursday and Friday...

a pattern change to more summerlike warmth and humidity expected thu
and Fri as upper level ridging builds to sour south... Resulting in
rising height fields in southern new england. Highs should be well
up into the 80s to perhaps over 90... But specific details this far
out remain uncertain. Dry weather probably dominates... But a few
showers t-storms can not be ruled out.
