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 am Wednesday morning
High pressure will remain over the northeastern states tonight as
hurricane maria drifts northward well off the north carolina coast.

Cirrus is forecast to be on the decrease tonight. However, low
clouds are expected to build back inland. Based on the anticipated
trajectory, it appears as though the low clouds will not get any
farther northwest than they did this morning. A mostly clear sky
over berks county, the lehigh valley, the poconos and northwestern
new jersey should allow for the development of patchy fog in those
areas, especially in the river valleys.

A northeast wind at 5 to 10 mph is expected on the coastal plain.

The wind should go light and variable farther inland.

Minimum temperatures are forecast to favor the 60s.

Short term 6 am Wednesday morning through 6 pm Wednesday
Little change is expected in the surface pattern for Wednesday with
hurricane maria remaining well off CAPE hatteras.

Any low clouds and fog at the start the day should lift and erode
gradually during the course of the morning.

We will mention a low or slight chance of showers in sussex county,
delaware and in CAPE may county, new jersey, as well as over the
adjacent waters. The showers will be on the outer edge of hurricane
maria's influence.

A northeast wind at 10 to 15 mph is expected on the coastal plain.

Wind speeds are anticipated to be less than 10 mph farther inland.

High temperatures are forecast to be mostly in the 80s with readings
not getting above the 70s at the coast.

Long term Wednesday night through Tuesday
Maria, which should be a tropical storm by Wednesday night, will
begin its anticipated NE turn and begin to move away from the coast.

Its lingering effects for surf will continue into the late week, but
overall the effects on our area will be minimal. It will be a breezy
period from Wednesday night into Thursday as the storm moves away
and high pressure builds in. A weakening cold front will also bring
cooler and drier into the area for the last part of the week. Highs
Thursday will be in the low 70s north and mid upper 70s south. These
readings will cool by 5 degrees for Friday. These temperatures will
be close to normal for the closing days of september. Overnight lows
will be cool too, with readings mostly in the 40s north and low mid
50s south starting Thursday night.

An upper trough will cross the area Friday through Saturday.

Overall, the weather thru the period will be fair, but scattered
showers are possible N W Friday and area-wide for Friday night and
Saturday. Temperatures will remain seasonably cool with highs in the
upper 60s to low 70s and lows will mostly be in the 40s north and
low 50s south.

A prolonged period of fair weather is expected for Sunday into early
next week. Expansive high pressure will build down from canada and
build over the area. Temperatures will remain within a few degrees
of normal.

Aviation 20z Tuesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

MVFR ceilings were lingering at mid afternoon at kacy and kmiv.

Conditions wereVFR at our remaining six TAF sites.

Low clouds are forecast to gradually work their way back inland
tonight, affecting all except krdg and kabe. However, patchy fog may
develop in the krdg and kabe vicinity for late tonight and early
Wednesday morning. The low clouds and fog are expected to lift and
erode gradually on Wednesday morning with most locations going to
vfr for the afternoon.

A light northeast wind is anticipated for tonight. A northeast wind
around 8 to 12 knots is expected for Wednesday at kphl, kilg, kpne,
kttn, kmiv and kacy. Wind speeds should be less than 8 knots at krdg
and kabe.

Outlook...

Wednesday night thru Friday...VFR.

Fri night thru Saturday... MostlyVFR with sct showers psbl.

Sat night thru Sunday...VFR.

Marine
High pressure over the northeastern states and hurricane maria well
off the north carolina coast will maintain a northeast wind on the
coastal waters of delaware and new jersey. Speeds will favor the 10
to 20 knot range. Gusts around 25 knots are anticipated for the
waters off southern new jersey and delaware.

Wave heights on our ocean waters are expected to build to 8 to 12
feet. As a result, the small craft advisory remains in effect. Waves
on delaware bay should be 1 to 4 feet and likely a bit higher right
around the mouth of the bay.

Outlook...

wed night thru Fri evening... SCA conditions. Sct showers wed
night and thu.

Fri night thru sat... Sub-sca conditions with sct showers fri
night and sat.

Rip currents...

powerful long period swells emanating from hurricane maria will keep
a high risk for the development of dangerous rip currents through
Wednesday along the coasts of delaware and new jersey. Also, we will
keep the high surf advisory in place for the coasts of atlantic
county, CAPE may county and sussex county (delaware).

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
