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
Very hot and humid conditions will impact the interior Monday
with record high temperatures. An approaching cold front will
likely trigger a few thunderstorms Monday afternoon and Monday
night, and some of the stronger storms could produce locally
heavy rainfall and gusty winds. Behind the departing cold
front, less humid and not as hot Tuesday and Wednesday then a
slight cooling trend for the end of the week.

Near term until 6 am Monday morning
935 pm update...

quiet weather continues overnight with lightly southerly flow
allowing higher dewpoint air to advect northward.

Therefore... Despite just some scattered high clouds, low temps
will only fall into the lower to middle 60s in most locations.

Not too concerned about low cloud fog potential... But can not
rule out the low risk for a few patches near the south coast
toward daybreak as higher dewpoint air continues to work into
the region.

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

anomalously warm airmass will advect into sne along northern
periphery of upper level ridge. 925 mb temps increase to 26-27c
across interior ma and with W SW boundary layer flow, this would
support highs into the mid upper 90s in the merrimack and ct
valleys, with hottest temps in NE ma. SW flow will keep ri and
se ma cooler in the mid 80s to 90 degrees, with upper 70s along
the south coast beaches and islands. With dewpoints climbing
into the upper 60s to near 70 degrees, heat indices will likely
reach 100 degrees for a few hours in the merrimack and ct
valleys where heat advisories will be issued.

The increasing heat and humidity will result in sbcapes
increasing to 1000-2000 j kg across the interior in the
afternoon. In fact, href probs indicating 60-70 percent probs
of 2000 j kg. Forcing for ascent is limited but this instability
supports at least widely scattered t-storms developing in the
afternoon. 0-6km shear increases to 30-35 kt so potential for a
few strong storms and can't rule out severe weather, but meager
mid level lapse rates will limit robust updrafts and likely
reduce severe threat. Pwats increasing over 2 inches so heavy
rainfall will be the primary threat, but a few of the stronger
storms could produce strong wind gusts. The main threat for
strong to severe storms will be across interior ma and northern
ct.

Monday night...

pronounced low level theta-e ridge axis with pwats up to +3 sd
sets up across sne ahead of southward moving cold front. Due to
meager mid level lapse rates, sfc based instability will
diminish but there is some elevated instability and forcing for
ascent increases ahead of the front. This will lead to risk for
showers and t-storms continuing into Mon evening and possibly
overnight based on timing of the front which doesn't reach the
south coast until Tue morning. Given the anomalous pwats, heavy
rainfall will be the main concern. It will be a warm and humid
night with dewpoints near 70, but drier air will be moving into
northern ma toward daybreak behind the front. Areas of fog,
locally dense, will likely develop near the south coast and
cape islands.

Long term Tuesday through Sunday
Highlights...

* dry, less humid Tuesday afternoon into Saturday
* near normal temperatures Thursday and Friday
* potential for some showers on Sunday
overview...

12z model guidance is in agreement with a strong high pressure
southern california with a large mid-level trough over quebec.

Southern new england will be on the edge of the upper level trough
and upstream of the mean axis. This will favor subsidence and dry
weather through this upcoming week. However, cannot rule out the
potential for a few showers, but very low confidence as ensembles
keep the region mostly dry. Pattern turns a bit more active Sunday
into early next week with a few disturbances moving in the flow.

Tuesday into Sunday...

a few lingering showers on Tuesday as a cold front sweeps through
the region. However, dewpoints and k values will be quickly dropping
in the late morning into afternoon and thus expect clearing skies
and dry weather. Otherwise, high pressure will dominate the area
late Tuesday into Wednesday as temperatures remain above normal.

Passing cold front on Thursday will be quite dry as moisture is
marginal. Cooler air will filter in behind this front which will
drop temperatures on Thursday into Friday to be closer to normal.

High pressure will dominate again on Friday lasting into the first
half of the weekend before precip begins to push into the region
Sunday Monday.

Aviation 02z Monday through Friday
Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Monday... High confidence.

MainlyVFR, but isold to sct showers t-storms likely developing
in the afternoon in the interior. Any stronger storms will be
accompanied by brief MVFR ifr conditions along with heavy
downpours and gusty wind. SW gusts around 25 kt developing,
especially eastern ma and ri.

Monday night... Moderate confidence.

Scattered showers t-storms with brief MVFR ifr and heavy
downpours in the stronger storms, especially in the evening.

Otherwise, stratus and fog will likely develop over the islands
and south coastal regions with ifr lifr conditions.

Kbos terminal... High confidence in taf.

Kbdl terminal... High confidence in taf.

Forecaster confidence levels...

low - less than 30 percent.

Moderate - 30 to 60 percent.

High - greater than 60 percent.

Short term through Monday night ...

tonight... High confidence. Winds and seas below sca.

Monday... High confidence. Increasing SW flow with gusts to 25 kt
developing over nearshore waters, including boston harbor and
narragansett bay. Persistent flow will also lead to building
seas above 5 ft by evening. Small craft advisories have been
issued.

Monday night... High confidence. SW gusts 20-25 kt diminishing
overnight, but 5+ ft seas will persist over outer waters. Areas
of fog developing will result in poor vsbys, especially over
south coastal waters.

Outlook Tuesday through Friday ...

Tuesday: winds less than 25 kt. Seas locally approaching 5 ft.

Tuesday night through Friday: winds less than 25 kt.
