area forecast discussion... Updated
national weather service gray me
1109 am edt Sun jun 16 2019

Synopsis
A slow moving cold front will drop south across the area today
before eventually sliding offshore tonight. Weak high pressure
will build over the area on Monday providing for a mostly sunny
day. High pressure will hold over the region Monday night and
Tuesday as a weak disturbance passes to our south. Low pressure
will move east out of the ohio valley Tuesday night and will
pass south of the region Wednesday and Wednesday night. Another
area of low pressure will approach from the west on Thursday and
will move through the region Thursday night and Friday. This
system represents our best chance of substantial rainfall in the
next 7 days.

Near term until 6 pm this evening
Update... Rain beginning to move into the area at this hour. I
have increased pop for SRN zones where rain is all but certain
with a sharp drop to zero chance for NRN zones. I also removed
thunder from the forecast. There is some small elevated
instability but I think any thunder will be too isolated to
warrant inclusion in the forecast. I have also dropped heavy
rain wording. It will rain but with highest QPF amounts less
than an inch it will just ruin grilling plans and no flooding
issues are expected.

Prev disc...

at 06z... A cold front extended from the rooftop of maine along
the international border then into the lower great lakes to a
1007 millibar low over northern ohio. NWS doppler radar mosaic
showed a broken area of convection along and ahead of this
boundary. For today... GOES water vapor imagery showed a shortwave
impulse over ohio. This impulse will race east along with its
1007 millibar low surface reflection on the sagging frontal
boundary. Clouds and scattered showers to start the day near the
international border then drier post frontal air with some
clearing with temperatures near 70. Further south... A mostly
cloudy day with temperatures in the 60s to around 70. It'll be a
humid day over southern sections as well as dew points creep
into the lower 60s. Showers will be most numerous over southern
new hampshire through southwest maine as that area remains in
close proximity to the frontal boundary. Shower activity should
increase in coverage as we head through the morning hours ahead
of the weak surface low and associated shortwave impulse and
there may be an embedded rumble of thunder or two. Showers will
taper by late today as the surface low and upper support race
offshore.

Short term 6 pm this evening through 6 pm Monday
Any lingering showers end this evening as the baroclinic zone
slides offshore. There'll be plenty of residual low level moisture
tonight... So I expect areas of low clouds and some patchy fog
to develop. Lows tonight in the mid and upper 40s across the
mountains with lower and mid 50s elsewhere. A partly sunny and
dry day Monday with a weak surface trough dropping south across
the area during the afternoon. Highs tomorrow will be in the
70s... With a few 80 degree readings over southern new hampshire.

Long term Monday night through Saturday
The extended period will start off with fair weather Monday
night. However, the next in a series of short wave troughs to
affect the area will come Tuesday. Fortunately, the main
baroclinic zone will remain well to our south. Therefore, most
of the rainfall should be focused near the sfc warm front across
southern new england and further south. However, some of the
rainfall may sneak into southern nh on Tuesday, and have
therefore kept chance pops going there. Broad cyclonic flow
should be in place aloft on Wednesday and may allow for
scattered showers and perhaps a thunderstorm or two during the
day. The next system of interest potentially arrives Thursday
afternoon into Friday as the mostly zonal flow amplifies some as
a stronger short wave trough approaches from the west. This
system represents our best chance at substantial rainfall
centered around Thursday night as sfc low pressure forms just to
our south.

Aviation 15z Sunday through Thursday
Short term through Monday ... Areas of MVFR in cigs, -shra and
isold -tsra with LCL ifr psb in fog. Precipitation ends this
evening with some areas of lingering MVFR CIGS with LCL ifr psb
in fog and stratus. Improving toVFR throughout aft 12z Monday.

Long term...VFR conditions are expected Monday night as high
pressure moves just off to our east. On Tuesday, a moistening
low level southeasterly flow develops and likely results in
lowering clouds and a chance of showers. MVFR conditions are
likely, with ifr conditions possible at coastal terminals.

Improvement is possible during the daylight hours Wednesday, but
should again deteriorate Wednesday night into Thursday.

Marine
Short term through Monday ... SCA has expired with seas now
below thresholds. We remain below SCA for the remainder of the
period under a weak pressure gradient.

Long term... Conditions should remain below small craft
thresholds Monday night through midweek. SCA conditions possibly
arise Thursday through Friday as low pressure tracks just south
of the waters.

Gyx watches warnings advisories
Me... None.

Nh... None.

Marine... None.

Near term... Legro
