Synopsis
Hurricane maria will move slowly northward off the coast of the
outer banks through Wednesday before turning sharply east-
northeastward into the open atlantic through the end of the week. A
cold front will move through the mid-atlantic on Thursday, and a
reinforcing front will progress through the area Friday and Friday
night. Cool high pressure will settle into the northeast this
weekend through at least early next week.

Near term until 6 pm this evening
A stratus deck, along with patchy fog, continues over most of
the area. There may be an hour or so after sunrise where the fog
briefly increases and becomes thicker, but should otherwise
dissipate shortly thereafter for most along and west of the
i-95 corridor. Closer to the coasts, however, due to the
onshore influence, it may take until the late morning hours for
the fog and stratus near the coasts and over the coastal plain
to dissipate.

High pressure remains over the area, and slowly lifts to the
north and east today. Meanwhile, hurricane maria is about 210
miles SE of CAPE hatteras, and will track to the north parallel
to the carolina coast today. As it does, NE winds will increase
to 15-20 mph with gusts up to 25 mph along the nj and de coasts.

Inland, NE winds will generally range from 5-10 mph. As such, a
cooler airmass spreads into the region, and highs today will be
about 5-7 degrees cooler than Monday. The coolest temperatures
will be across the coastal plain of nj and into most of de and
ne md, where highs will range from the mid 70s to around 80.

West of the i-95 corridor, though, highs will climb into the mid
and upper 80s. Exception will be the poconos, which will be in
the upper 70s to around 80.

Some outer rain bands associated with maria will lift to the
north, and some light showers may make it into parts of de ne
md extreme southern nj, but the high should be strong enough to
keep the bulk of the showers suppressed to the south. Any rain
that does fall will only result in light QPF amounts.

Short term 6 pm this evening through 6 am Wednesday
Low clouds and patchy fog will develop once again across the
coastal plain and the DELMARVA late tonight. NE winds will
diminish to 5-10 mph along the coasts and to 5 mph or less
inland. Meanwhile, maria will begin to weaken to a tropical
storm as it begins to sharply curve out to sea. A few outer rain
bands may move into southern portions of the forecast area, but
not expecting much, if any, qpf. Lows tonight generally in the
low 60s to the north and in the upper 60s to around 70 to the
south.

Long term Wednesday through Monday
Main forecast concerns for the long-term period are
precipitation chances Wednesday and again Friday night and
Saturday and a sharp downward trend with temperatures versus
what has been observed recently.

Analysis of the 00z operational model suite suggests that the
overall large-scale pattern is decently agreed upon, but rather
large discrepancies exist with the smaller-scale vorticity
maxima that will be progressing through and or affecting our
region through the period. Additionally, poor run-to-run model
continuity continues, owing largely to uncertainty with the flow
pattern in the northern pacific and the apparent substantial
influences downstream.

At 12z Wednesday, maria will be off the coast of the outer
banks. A potent vort MAX will be progressing through ontario
with southwesterly midlevel flow between the two. Although the
main impacts from maria will be well south east of the area, the
pressure gradient will be tightening in the southern cwa, so
expect breezy conditions to develop in southern delaware and far
southeast new jersey. Northeasterly surface flow should keep the
area socked in clouds much of the day, with only gradual
improvement from northwest to southeast. Some showers are
possible, especially near the coast, as maria makes its closest
approach to the area. However, a considerable portion of the
model output is dry through Wednesday night. The exceptions are
the 00z cmc ecmwf, which indicate some QPF close to the coast.

The totals from the cmc look overdone, but the geographic
agreement with the ECMWF suggests that precipitation chances
should remain. I did lower them considerably northwest of i-95,
where there is little remaining evidence of sufficient lift for
showers. One noteworthy development: the 00z ECMWF is
considerably slower and continues on the west side of the
guidance with the track of maria. By Thursday, it becomes an
outlier with the position of maria, so I neglected to give the
new simulation strong weighting in the forecast.

As the ontario trough moves rapidly east-northeast into the
canadian maritimes on Thursday, maria should begin the eastward
turn. The ECMWF is weakest with this trough and considerably
more sluggish in advancing maria farther offshore - this does
lower confidence in Thursday's forecast a little bit. A surface
low will develop and progress rapidly eastward through quebec
and new brunswick, with a cold front sweeping across the eastern
seaboard Thursday. Cooler and noticeably drier air will seep
into the mid-atlantic upstream of the front, with forecast highs
Thursday around 10 degrees colder in the urban corridor and up
to 20 degrees colder in the southern poconos. The change should
be less severe near the coast (which will be cooler on Wednesday
given the onshore flow). Kept most of Thursday dry given the
subsidence upstream of the front.

An upstream shortwave trough digs southeastward into the great
lakes Thursday night, and this is where much of the forecast
uncertainty lies. The GFS is much more progressive with this
trough than the cmc and especially the ecmwf. The GFS has
trended stronger with the first trough in eastern canada and
weaker with the second, which does not agree with the recent
trends of the NAM or ecmwf. Additionally, there is very large
variation in the upstream flow run-to-run with the gfs. The
stronger agreement between the cmc ECMWF made me lower the
weighting of gfs-based guidance Friday onward, and I may not
have done so enough.

The main effects on the forecast are with precipitation chances
Friday night and Saturday, with the GFS about 6-12 hours faster
in general (more Friday night versus early Saturday for the
cmc ecmwf). For now, kept the highest pops late Friday night
(a compromise of the two camps), but my suspicion is that pops
need to linger into a portion of Saturday, especially for the
eastern zones. Trended this direction with the forecast, but
expect further (perhaps substantial) changes with pops during
this period.

Cool dry high pressure moves in thereafter, with a prolonged
period of near to slightly below seasonal temperatures Saturday
onward. Models have large phase amplitude variations with the
midlevel ridge developing in the east during this period, so the
duration of the cool dry spell is a little uncertain at this
point.

Aviation 12z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Fog and stratus producing lifr conditions at kacy kmiv will be
slow to dissipate, and conditions will probably not lift toVFR
until midday or so. Otherwise, ifr conditions in patchy fog and
stratus along and east of i-95 will improve toVFR shortly after
sunrise.

Vfr west of i-95 through the TAF period.

Fog stratus looks to redevelop late tonight with sub-vfr conditions
likely once again.

E-ne winds will increase to 5-10 kt, except at kacy, where e-ne
winds will increase to 10-20 kt.

Lgt vrb winds tonight.

Outlook...

Wednesday: MVFR ifr conditions possible, especially from the
urban corridor eastward, with gradual improvement toVFR from
northwest to southeast during the day. Some showers possible at
kmiv kacy. Northeast winds 5 to 15 kts with stronger gusts near
the coast (up to 25 kts or so). Confidence below average.

Wednesday night and Thursday: winds should become
north northwest as a cold front sweeps through the region. May
see some lingering showers low clouds at kmiv kacy Wednesday
night. Speeds should reach 10 to 20 kts on Thursday, with higher
gusts possible. Confidence average.

Thursday night and Friday: predominantlyVFR. Northwest winds 5
to 15 kts. Confidence above average.

Friday night and Saturday: showers and localized sub-vfr
cigs vsbys possible. Winds generally north or northwest around
10 kts. Confidence well below average.

Marine
Small craft advisory continues today and tonight for the ocean
waters. Seas on the ocean will build to 9-11 feet. NE winds will
range from 15-20 kt with gusts up to 25 kt for southern nj and
de ocean waters. Otherwise, NE winds range from 10-15 kt.

With these increasing offshore seas, can expect breaking waves at
the shores of around 7 feet at southern nj and de beaches. A high
surf advisory has been issued for tonight through Wednesday for
southern nj and de coastal areas.

Outlook...

Wednesday: northeast winds with gusts above 25 kts likely in the
southern nj de coastal atlantic, trending lighter in delaware
bay and the northern central marine zones. Seas near 10 feet in
the atlantic, with rough surf likely. A high surf advisory
continues for the southern nj delaware beaches. Showers
possible.

Wednesday night: gradual decrease in winds, though advisory-
level gusts still possible south of atlantic city. Seas will be
slow to decline. A chance of showers.

Thursday and Thursday night: cold frontal passage will increase
winds to advisory level in the atlantic waters and potentially
delaware bay. Seas well above advisory criteria.

Friday: seas nearing but likely still above 5 feet, but winds
should diminish below advisory criteria.

Friday night and Saturday: sub-advisory conditions expected, but
a chance of showers.

Rip currents...

due to swells emanating from hurricane maria, there continues to be
a high risk for the development of dangerous and life threatening
rip currents for the ocean beaches today and tonight.

The rip current risk will likely be in the high category Wednesday
and Thursday as long-period southeasterly swells from maria
continue. Swell heights around or above 10 feet on Wednesday will
likely generate high surf beach erosion issues for much of the surf
zone but especially for southern new jersey and delaware.

Overall, not a good time to spend at the beach the next few
days.

Phi watches warnings advisories
Pa... None.

Nj... High rip current risk through Wednesday afternoon for njz014-
