Synopsis
Bermuda high pressure will remain in control of the weather much of
the weekend. A few weak system will move north of the area tonight
and Saturday. A strong cold front will approach Monday and cross the
area by Tuesday. Cooler and drier air will follow this front and
remain into the middle of next week. High pressure will settle
across the area from the great lakes region. &&

Near term until 6 am Saturday morning
**excessive heat warning in effect**
main story in this near term period is the building mid-level ridge
the excessive heat. Latest 2 pm observations show dewpoints in the
middle to upper 70s and heat indices in excess of 105. In the most
urban environments overnight tonight, temperatures may not drop
below 80 degrees. And that's the issue... Lows around 80 will offer
very little recovery before temperatures climb once again after
daybreak Saturday. Elsewhere, low temperatures will be in the 70s,
this includes the poconos and NW nj.

It appears the majority of the region will remain lightly capped
into this evening. This will help to prevent convection. But there
are some showers and thunderstorms developing out ahead of the mcv
well to our west. These showers and thunderstorms may clip our zones
tonight north of i-78.

Skies will be partly cloudy north to mostly clear south overnight.

Winds will be light from the southwest. Some light fog is possible
around daybreak.

Short term 6 am Saturday morning through 6 pm Saturday
**excessive heat warning in effect**
Saturday will be the hottest day of the year thus far (Sunday could
top Saturday). Actual air temperatures will be in the 90s. The most
urban areas will approach 100. Dewpoints will be similar to today,
in the mid to upper 70s. So with the added heat, apparent
temperatures will exceed today and climb into the 110 to 115 range.

Winds will be out of the west southwest 10 mph or less. There will be
little breeze to offset the heat. The exception will be the beaches,
close to the water and where a seabreeze should develop. With the
westerly flow, the seabreeze will not penetrate far inland.

With all the heat, soundings show a capped environment most of the
day tomorrow. There may be a little window of opportunity for
convection to develop across terrain or the surface trof. No more
that slight chance pops have been added across our western zones.

Most will remain dry.

Long term Saturday night through Friday
**excessive heat warning in effect into Sunday.**
a transition from heat wave back to below normal temperatures
during the long term. As usual, a round of tstms will occur
during the transition. The extremely humid air mass will cause
the tstms to be accompanied by heavy rains and possible flooding.

Sat night... Mostly fair but a few showers tstms possible across the
southern poconos. Hazy. Hot and humid. Lows in the upper 70s to low
80s.

Sunday... Continued hot and humid, but TSTM chances higher then sat
with an approaching cold front nw. Highs again upper 90s with some
100's in some areas. Excessive heat warnings will continue.

Sunday night thru Monday night... A cold front slowly crosses the
area. Occasional tstms with severe weather and flooding possible.

Highs Monday about 10 degrees cooler than Sunday (mostly low 90s),
but humidity still high.

Tuesday and Wednesday... A few showers early across delmarva,
but overall fair and much more comfortable. Highs will be a
little below normal with readings Tue Wed in the low mid 80s.

Thu fri... Much uncertainty. Temperatures back near normal.

Mostly fair, can't rule out a few afternoon showers both days.

Aviation 19z Friday through Wednesday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Tonight... MainlyVFR. There could be some MVFR visibilities across
the climatologically favored terminals toward daybreak. Variable
wind 5 kt or less.

Saturday... GenerallyVFR. MVFR is possible due to visibility
restrictions in haze... Mainly in the morning. West-southwest wind 5
to 10 kt.

Outlook...

Saturday night... Hazy. MVFR vsbys possible.

Sunday thru Tuesday... Sct tstms with low vsbys and CIGS possible.

MVFR haze outside of the showers tstms. Best chc for tstms Monday.

Wed...VFR. Fair weather.

Marine
Tonight... Sub-sca conditions expected. There could be some wind
gusts from the southwest in excess of 20 kt this evening, but they
will subside into the 10 to 15 kt range overnight. Seas will be in
the 3 to 4 foot range.

Saturday... Sub-sca conditions expected. Winds less than 10 kt with
seas 2 to 3 feet.

Outlook...

winds will remain well below SCA criteria Saturday night and early
Sunday. After that, winds and seas will increase, but probably still
remain sub-sca as a cold front approaches the waters. Thunderstorms
with strong winds gusts are possible Monday into Tuesday.

Rip currents...

breaking waves around 2 to 3 feet are expected along with a medium
period south to southeast swell. As a result, there should be a
low risk for the development of dangerous rip currents for the
rest of today.

Conditions are forecast to be similar on Saturday, with the low
risk expected to continue.

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.
