Synopsis
Jose will pass south and east of CAPE cod today and tonight, and
could produce some scattered showers today and gusty winds
along the coast into Thursday. Otherwise high pressure will be
the main feature and stay in place across the region into early
next week, with temperatures running above normal through the
period, and mainly clear skies Thursday through Monday.

Near term until 6 pm this evening
945 am update: low clouds stratus continue across most of the
area except over northern nh and the western mountains of me
where drier air mass has worked into the area producing partly
sunny conditions. Light north winds will continue to drag drier
air from the north into southern areas by later in the afternoon
and tonight so some clearing will slowly take place from north
to south. Keeping low pops along the immediate coast but
expecting the light showers offshore to stay there. Only minor
adjustments to temps based on latest mesonet data.

8 am update: with north winds and enough mixing occurring, have
taken out mention of fog for the morning although low stratus
will persist.

640 am... For the most part forecast is unchanged, as we look
for winds to increase from the nne this morning, and becoming
breezy by this afternoon with some gusts nearing 30 mph on the
coast. Showers in the outer bands of jose continue to struggle
to survive much past the coast as they run into the ridge and
lose forcing as well as encountering drying air.

Previously... As the center of jose passes S and E of CAPE cod
today, it will also begin to exhibit some effects of a brief
extratropical transition as it gets tugged on by a trough
passing well to the n. This should help expand its wind field a
bit starting today, and will see winds increase during the day,
with some gusts of 25-30 mph possible on the coast late today.

Showers associated with jose outer bands are working n-nw
onshore but continue to struggle as the run into the strong
ridging. Some clearing is possible this afternoon, mainly in the
north and in the ct valley N of kleb, but otherwise it will be
mainly cloudy. Highs will range from the upper 60s to the mid
70s, warmest in the ct valley.

Short term 6 pm this evening through Thursday night
Jose will begin to slow its eastward progression tonight and
eventually become nearly stationary south of the gulf of me late
Thursday. The combination of jose lingering and sfc ridging
building to our north will help maintain a strong pres gradient
and allow breezy conditions to continue overnight into Thursday.

In fact, may see the strongest winds on Thu as flow shifts more
nnw and mixing improves in caa, albeit weak caa, and from the
mechanical effects of downsloping.

As for any additional shra from jose, it looks like any chc of
precip will be done by this evening, so mainly dry after that.

Clouds should begin to erode from n-s overnight, with mainly
sunny conditions on thu. Lows tonight will stay mild, with the
wind keeping up and keeping the atmosphere mixed, with lows in
the mid 50s N to low 60s in the s. Highs on Thu will be aided by
the strong downslope and should work to counteract whatever
weak CAA exists, with highs mostly in the 70s, and approaching
80 in the ct valley.

Also have extended the heavy surf advisory along the coast
through tonight at least, when coastal directed swell looks to
be at its greatest. May need to push this into thu, but will let
the day shift look at it.

Long term Friday through Tuesday
The models are in decent agreement on the long wave pattern
through the upcoming weekend. We begin the period with an upper
ridge across northern new england and the remnants of jose
meandering well offshore to our south and east. The ridge will
continue to strengthen as we head into the weekend at which
time the remnants of jose will be kicked well offshore. The
eastern ridge and western trough will hold across the conus
through the start of the new work week with predominantly dry
weather and abnormally warm temperatures to continue. By mid
week... Hurricane maria may be lurking off the eastern seaboard
similar to the current tropical system jose.

Aviation 14z Wednesday through Sunday
Short term... Coastal terminals should see only very limited
improvement to ifr for a few hours today, but may slip down to
lifr this evening, despite N winds gusting to 20-25 kts at
times. Inland terminals will see better improvement this
afternoon. All terminals should begin to improve late tonight
as drier air working in on those gusty winds, withVFR expected
everywhere by sunrise thu. The gusty winds will continue
through thu.

Long term...

fri... Ne sfc wind gusting to 25 kt psb at coastal TAF sites.

Marine
Short term... 8 am update: have dropped the gale warning to a sca
over the southern waters for today as current conditions and
guidance all point to winds not exceeding SCA conditions.

Holding onto SCA for now across the rest of the waters. Seas
will peak tonight and generally in the 7-11 ft range outside of
the bays.

Long term...

fri... Small craft seas and wind gusts are probable outside the
bays.

Sat - sun... Lingering small craft seas are likely outside the
bays.

Tides coastal flooding
Long period swells will continue through tonight. High tide at
portland is 10.6 ft around midnight, and conditions may be a
little worse tonight given slightly greater swell, and possibly leading
to minor splash over and some beach erosion.
