Synopsis
High pressure over new england will weaken and drift eastward
through Tuesday. Low pressure will cross to our north, dragging a
cold front through the mid-atlantic Wednesday night. High pressure
will build in from the southwest for Thursday and Friday. A cold
front will cross the region Saturday followed by a return to high
pressure for Sunday and Monday.

Near term until 6 pm this evening
High pressure will remain NE of the area today. A moderate NE to e
flow around the high will continue with gusty conditions, especially
along the coast. Sky cover will be mostly clear inland and partly to
mostly cloudy elsewhere. Locations across de and S E nj will see the
most clouds today. High temperatures will remain cool with readings
topping out in the low 70s N W to the mid 70s elsewhere. There may
be some light showers across the SE areas, but pops will be held at
slight chc, since confid in the occurrence is not the greatest
attm.

Short term 6 pm this evening through 6 am Tuesday
More of the same in the short term. The high will begin to weaken,
so the winds will decrease. The flow will still remain onshore, so
added clouds and still a small chc for a shower will continue across
ern nj and de. Lows tonight will remain cool, with low mid 50s
across the N W areas and upper 50s low 60s elsewhere.

Long term Tuesday through Sunday
High pressure remains to our north on Tuesday with the high starting
to slide to the east through Wednesday, breaking down as its moves
offshore. This will keep the cooler easterly flow across the
forecast area on Tuesday and Wednesday. With the airmass modifying,
even in the prolonged onshore flow, we should see temps warm into
the 70s and lower 80s across the region on Tuesday, with better
chances for lower 80s on Wednesday. Expect conditions to remain
fairly cloudy as a result of the easterly flow and some light
precipitation is also possible on Tuesday, mainly across southern
parts of the forecast area.

The bigger story for Wednesday will be the arrival of a cold front
later in the day. Warming ahead of the front and a turning of the
winds to a more southerly direction should aid in destabilization of
the atmosphere. Showers and thunderstorms will be possible from
Wednesday afternoon through Wednesday night. Rainfall amounts aren't
that impressive with the latest model runs and there appears to be
good storm motions so expect everything to be fairly progressive
through Wednesday night.

Once the front clears the area, we should see a return to high
pressure and some dry conditions. A weak cold front approaches the
region from the west on Friday but it looks like it peters out
before it reaches our area. Overall expect nice conditions to
prevail across the mid-atlantic from Thursday through Saturday.

The next system will arrive around Sunday, and this cold front looks
to be a bit more substantial than the Friday front. However, there
are still quite a few differences in the guidance with respect to
timing and moisture, so we have made few changes to the forecast.

Plenty of time for the models to come in alignment as we get closer
to the weekend.

Aviation 08z Monday through Friday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Today... Ne to E onshore flow will continue.VFR most of the time,
but some MVFR CIGS possible kmiv kacy this morning and perhaps into
the early afternoon. Gusty winds nearshore kacy with g20 knots
possible.

Tonight... A continuation of the onshore winds, butVFR expected most
of the time. Again, some lower CIGS near the coast possible. This is
not reflected in the current tafs with confid in this occurring not
the best.

Outlook...

Tuesday... MainlyVFR conditions expected. Light showers possible
south and west of kphl which may cause MVFR or lower conditions to
occur. Easterly winds around 5 to 10 knots with gusts up to 15 knots
possible.

Wednesday... MainlyVFR conditions expected. MVFR or lower possible
in showers and thunderstorms. Light and variable winds up to 5
knots.

Thursday... MainlyVFR conditions expected. Northwest winds around 5
to 10 knots.

Friday... MainlyVFR conditions expected. Northwest winds around 5 to
10 knots will become west and then southwest by the afternoon.

Marine
Sca winds and seas will continue today and tonight with a decent ne
to E flow around the strong high to the ne. The high will weaken
later tonight with lessening winds and then seas. We will extend the
sca flag on the ocean through the overnight. Only some widely sct.

Showers are possible today and tonight with the humid NE flow.

Outlook...

Tuesday... Small craft advisory conditions may linger into Tuesday
morning as seas will be around 5 feet. Seas are expected to subside
and drop below 5 feet around midday. East to northeast winds around
10 to 15 knots with gusts around 20 knots.

Wednesday... Easterly winds around 10 knots. Seas 2 to 4 feet.

Thursday... Northwest winds around 10 knots. Seas 1 to 3 feet.

Friday... West to southwest winds around 10 to 15 knots. Seas 1 to 3
feet.

Rip currents...

a high risk of rip currents is expected today and tonight.

Continued onshore flow and rough surf, with wave heights near
or above 5 ft, will continue through today and may possibly
extend into Tuesday.

Tides coastal flooding
A brisk northeast wind is forecast to continue along the coasts
of new jersey and delaware through late today. The wind is
expected to become east with speeds slowly diminishing on tonight
and Tuesday.

The onshore flow may result in spotty minor tidal flooding
around the times of the late afternoon evening high tide today
and Tuesday. However, the minor flooding is not anticipated to
be widespread enough to warrant an advisory at this time.

The base level of the early morning high tides are considerably
lower than those of the late afternoon evening high tides, so
no issues are expected early in the day today or Tuesday.

Once we get past the early week's onshore flow, we will begin
to experience particularly high astronomical tides associated
with the upcoming new moon phase. As a result, there is another
potential for at least some spotty minor tidal flooding from
late this week into the holiday weekend.

Equipment
The NWS radar at dover de, (kdox) is back in service.

Phi watches warnings advisories
Pa... None.

Nj... High rip current risk through this evening for njz014-024>026.

De... High rip current risk through this evening for dez004.

Md... None.

Marine... Small craft advisory until 6 am edt Tuesday for anz450>455.

Small craft advisory until 8 pm edt this evening for anz430-

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.
