Synopsis
A weak cold front passes across the mid atlantic states today.

High pressure will follow tonight and Wednesday. This high moves
offshore during the end of the week. Eventually, another weak cold
front will cross the mid atlantic states Saturday night or Sunday.

Near term until 6 pm this evening
An upper-level trough is forecast to sharpen eastward today as it
moves into the northeast and mid atlantic. This will drive weak low
pressure well to our north, however a few weak cold fronts or
surface troughs will continue to push eastward. The first one early
this morning along with a weak short wave is responsible for a band
of downpours. These has now just about exited our area. We then turn
our attention to the west.

A more pronounced area of short wave energy is forecast to arrive
from west to east later this morning and through the afternoon. This
looks to be accompanied by either a weak cold front or surface
trough. While the trough aloft is forecast to be sharpening some as
it shifts eastward along with gradual cooling aloft, the bulk of the
lift is more focused to our north and west. The majority of the
model guidance is therefore showing much of the convection just to
our north through west. There should however be enough moisture and
lift along with at least some instability through the day to pop a
few showers or thunderstorms. This appears to be focused initially
early this morning just to our west, while a few other showers
continue to initiate to our southwest which moves across parts of
our southern zones through mid-morning. Since the overall coverage
is less certain this afternoon, we kept pops in the slight chance to
low chance range.

High temperatures are a blend of continuity, MOS and some high-res
guidance. Given lower heights and thickness values, the afternoon
high temperatures are forecast to be a bit cooler than
yesterday.

Short term 6 pm this evening through 6 am Wednesday
The axis of an upper-level trough is forecast to move across our
area during the overnight. Any shower or thunder is expected to end
very early as the main short wave energy is offshore. There should
then be some subsidence overspreading the area as surface high
pressure starts to arrive toward daybreak.

The sky is anticipated to become mostly clear as a result with any
clouds due to daytime heating flattening and then dissipating in the
evening. We are expecting enough drying along with wind above the
surface to limit any fog development overnight. Low temperatures are
mostly a blend of continuity and mos.

Long term Wednesday through Monday
Highlights:
1. Heat index values near 100 possible for the urban corridor
Saturday.

2. Highest chance of thunderstorms centered on later Saturday
into Sunday when isolated svr may occur.

500 mb: a cold trough over the northeast usa tonight weakens to
the maritimes by Thursday night as heights rise-warm over the
mid-atlantic states. The warm ridge aloft, almost 2sd above
normal, on Saturday over the northeast gives way to a broad
trough over our area early next week.

Temperatures: calendar day averages will be about 5 degrees below
normal Wednesday average near normal Thursday then 5 to 8 degrees
above normal Friday through Sunday, cooling slightly on Monday. For
june, the result should be an average temperatures generally 1 to 2
degrees above normal at our NWS primary climate sites except
around 1 to 1.5 degrees below normal at mount pocono.

Forecast basis: a 50 50 blend of 00z 27 GFS nam MOS Wednesday-
Thursday, 00z 27 gfsmex MOS Thursday night-Friday and then only
dewpoints MAX min temps from the 0601z 27 wpc grids for d4-8.

Other guidance including pops sky wind was continuity from the
330 pm Monday forecast.

The dailies...

Wednesday... Mostly sunny. Westerly wind.

Wednesday night... Clear, then high clouds toward dawn. Light
southwest wind.

Thursday... Partly to mostly sunny (high clouds early, CU and ac
fields afternoon-night in waa. Southwest wind gusty to 25 mph
during the afternoon diminishes somewhat at night but still a
stirring mild wind. Small chance of a shower showers late or
night except a thunderstorm north of i-78. SPC d3 consideration,
especially with bulk shear. Mlc is rather paltry Thursday so
from my view, this a leftover gusty thunderstorm Thu night.

Friday... Partly to mostly sunny. Southwest with gusts probably 20
mph or less. Heat index should rise to 95 to 97 i-95 corridor.

Saturday... After predawn patchy fog or stratus, partly to mostly
sunny. Southwest wind. Thunderstorm potential ahead of cold
front later in the day or at night. Mlc 1800j. Bulk shear is
currently modeled low. Widespread heat index of 95 to 100 i95
with a wpc around 30 percent probability of hi in phl.

Sunday... Partly to mostly sunny. Depending on psn of the cold
front there could be leftover showers and tstms. West southwest
wind.

Monday... Chance of a shower in the fcst but for now odds favor a
decent Monday. Low confidence on this day:

Aviation 10z Tuesday through Saturday
The following discussion is for kphl, kpne, kttn, kabe, krdg,
kilg, kmiv, kacy and surrounding areas.

Today...VFR overall with a ceiling at times at or above 6000 feet. A
few additional showers possible this morning, then isolated to
perhaps scattered showers storms should occur this afternoon. Our
confidence regarding timing especially this afternoon is low and
therefore a mention is not included in the tafs. Mostly light and
variable winds, becoming west or west-southwest and increasing to
around 10 knots later this morning and afternoon. Some local gusts
up to 20 knots are possible this afternoon.

Tonight... Any spotty shower storm ends early, otherwiseVFR with any
lingering clouds tending to dissipate. West to northwest winds
mainly 5 knots or less.

Outlook...

Wednesday...VFR. Mainly a west wind.

Wednesday night...VFR. Light southwest wind.

Thursday...VFR with occasional variable cigs AOA 5000 ft.

Southwest wind gusts to around 25 kt in the afternoon. Chance of
a shower.

Friday...VFR. Southwest wind may gust to near 20 kt in the
afternoon.

Saturday... Patchy ifr conditions possible predawn in fog or stratus.

ThenVFR most of the day. Southwest wind. Thunderstorms ahead of
a cold front are expected but timing uncertain.

Marine
The conditions are expected to remain below small craft advisory
through tonight. A southwesterly wind will become westerly late in
the day and tonight as a weak cold front moves offshore. This
offshore flow will increase at times tonight with some gusts to near
20 knots. A few isolated thunderstorms will be possible mainly this
afternoon.

Outlook...

Wednesday... No marine headline. Rather quiet sea state.

Thursday... SCA possible for the near shore waters in the afternoon
then a possible atlantic waters SCA for hazardous seas during Thursday
night.

Friday and Saturday... Just below SCA threshold.

Rip currents...

the forecast conditions for today should result once again in a
low risk for the development of dangerous rip currents.

Climate
June average temperature: temperatures are expected to generally
average 1 to 2 degrees above normal at our NWS primary climate
sites except around 1 to 1.5 degrees below normal at mount
pocono.

Phi watches warnings advisories
Pa... None.

Nj... None.

De... None.

Md... None.

Marine... None.

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.
