* WINDS AND SEAS...Southeast winds 15 to 25 kt with gusts up to 
  35 kt. Seas 6 to 9 feet.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Small Craft Advisory means that wind speeds of 25 to 33 knots,
or seas 5 feet or greater, are expected to produce hazardous wave
conditions to small craft. Inexperienced mariners, especially
those operating smaller vessels, should avoid navigating in these
conditions.

A Gale Watch is issued when the risk of gale force winds of 34 to
47 knots has significantly increased...but the specific timing
and/or location is still uncertain. It is intended to provide
additional lead time for mariners who may wish to consider
altering their plans.

Area Forecast Discussion
National Weather Service Boston/Norton MA
1020 PM EDT Thu Apr 25 2019

.SYNOPSIS...

Lifting warm front into Friday will bring scattered showers and
perhaps a rumble of thunder. A more stout cold front will sweep
the region Friday night with widespread rain and embedded heavy
showers, possible thunderstorms. Leftover showers through mid-
morning Saturday, then drier and cooler air pushes across the
region on gusty west winds. Weak low pressure tracks near or just
off the S coast, bringing scattered showers late Sunday through
Sunday night. Another brief dry period forecast for Monday, then
may see unsettled conditions for a good portion of next week.

&&

.NEAR TERM /UNTIL 6 AM FRIDAY MORNING/...

10 pm update ...

Scattered showers becoming more widespread will edge N into S
New England overnight into Friday morning. Have upped PoPs
accordingly and altered to categorical, confident wording of
certain coverage.

Increasing sub-tropical, theta-E axis undergoing isentropic
ascent beneath increasing diffluence aloft out ahead of a
potent, parent low lifting N into the E Great Lakes region.
Increasing precipitable waters to around 1-inch as H85 dew-
points approach 10C. Increasing low-level winds along with
surface dewpoints rising towards the 60s, accompanying weak
instability as lapse rates become conditionally unstable and
moist-adiabatic. Lows remaining stable, hovering around the mid
to upper 40s.

But a nod to 0z soundings. Look at OKX / Upton NY versus those N
and upstream, CHH / Chatham MA especially. A lot of dry air to
overcome, so it will take a bit of time for shower coverage to
become more widespread as top-down moistening evolves.

Nevertheless, expect it to be widespread during the Friday AM
commute. Likely roadway issues with some lower visibility.

Preference to near-term, high-res solutions. The 12z HREF is not
doing terribly bad as well.

&&

.SHORT TERM /6 AM FRIDAY MORNING THROUGH FRIDAY NIGHT/...

Friday...

Surface low tracks from the eastern Great Lakes Region into far SE
Ontario, while associated warm front continues to push northward.
Warm front may not fully push north of our area, with occluded
front/triple point/secondary low potentially headed towards SNE. A
broad area of ascent for our region, with deepening of moisture
ahead of and behind the warm front, and precipitable water
increasing to 1-1.5 inch. Low level jet of 40 to 50 kts develops by
late Friday. While the whole day may not be a washout, there will be
showers at times. Will have likely to categorical pops for the day.
There will be a low level inversion north of the warm front, however
mid and upper level lapse rates are moderately steep at times, so
can not rule out some rumbles of thunder. At this time, thinking QPF
of 0.25 to 0.75 inch during the day. Some gusts 25 to 30 mph during
the afternoon, mainly along the Cape/Islands. Highs in the 50s to
low 60s.

Friday night...

Showers continue as main low tracks northeastward into southern
Quebec, while triple point low tracks near or into SNE, followed by
cold front sweeping thru our area late. Moisture along/ahead of
triple point and cold front is robust, with PWATs around 1.5 inch.
Strong winds aloft with H925 winds around 40-60 knots Friday night.
Plan to have categorical pops for this timeframe. Can't rule out
some wind gusts 25-35 mph with embedded thunderstorms.

This system is fairly progressive, hence rainfall amounts during
Friday night should range mainly from 0.50 to 1.0 inch. Elevated
instability and anomalous PWAT plume allows for a few higher
rainfall totals.

An additional concern for Friday night will be the combination of
the triple point low, marginal surface based instability with
temps/dew points in the mid and upper 50s in the warm sector,
accompanied by strong low level and deep layer shear. This may
support a few rotating storms but will likely remain elevated given
lack of surface based instability. Nevertheless will have to watch
how this evolves with later model runs.

The cold front and triple point low sweep northeastward and away
from our area by daybreak, taking most of the showers as well. There
is a chance for lingering light showers/light rain towards daybreak.

Prior to the cold frontal passage, will likely see temps rising a
few degrees as the higher dewpoint air moves in. Then late at night
temps fall to the 40s across much of the far interior, upper
40s to mid 50s to the east.

&&

.LONG TERM /SATURDAY THROUGH THURSDAY/...

Highlights...

* Dry conditions Saturday into Sunday
* Showers arrive late Sunday/Sunday night
* Unsettled conditions forecast for Monday night through
  Thursday

Overview...

Continued fast moving mid level steering flow across the
northern tier states remains in place into early next week.
Some amplification develops across the western U.S., which
should allow H5 ridging to build early next week across the
east. However, this may put us into an increasingly moist mid
level steering flow by mid to late week with continued fast
moving systems in this flow. Timing of these systems beyond
Monday in question, which lends to lower confidence.

Details...

Saturday through Sunday...

Scattered showers linger through midday Saturday as the cold
front moves offshore and the parent low lifts NE. Drier
conditions move in during the afternoon. Good low level mixing
arrives, especially along the S coast where the greater low
level jet will be located. Expect gusts up to 20-30 kt, highest
along the S coast and the higher inland terrain, which should
slowly diminish Saturday night.

Another fast moving weak low pressure center shifts E in the
nearly zonal mid level steering flow Saturday night, which
should push across the region on Sunday. May see some briefly
heavy downpours along the S coast from midday through Sunday
afternoon.

High temps both days should reach the 50s, but may hold in the
mid- upper 40s across the E slopes of the Berkshires.

Monday through Thursday...

While a progressive mid level steering flow continues, the
overall pattern begins to become somewhat amplified with a more
SW component by around Tuesday. Still expect fast moving weather
systems to push along in this flow.

Only timeframe for generally dry conditions looks to be Monday
morning through early afternoon before another low starts to
approach with more showers. Timing issues in place amongst the
12Z model suite thanks to this fast flow aloft, so lower
confidence on timing of individual systems as they move along.

At this point, some models are signaling that a deformation
zone may set up close to or across the region as these systems
move along. So, could see unsettled conditions for a good
portion of the Tuesday through Thursday timeframe.
