High pressure builds over the mid- atlantic region through
today. The high will move offshore Thursday and Friday, returning
our area to southwest flow. Another weak cold front is expected
this weekend, bringing a chance of showers through early next
week, especially if the front stalls.

Near term through today
Early this morning... Mostly clear. Light northwest winds.

Today... Sunny or mostly sunny and comfortably cool for summer
with few or sct sc 16z- 21z AOA 5000 ft, mainly northwest of
i-95. West northwest wind gusting 15-20 mph this morning
becoming more westerly this afternoon and diminishing slightly.

Dewpoints in the 40s while MAX temps 2 to 7 degrees below
normal. One of the nicest days we'll see for quite a while.

Forecast basis: a 50 50 blend of the 00z 28 GFS nam mos.

Short term tonight
Tonight... Mostly clear with some cirrus after midnight, especially
northwest of i-95. Lowered 50 50 blended 00z 28 mos GFS nam temps
a degree or two from that guidance due to light wind. These
temps 1 to 4 degrees below normal.

Long term Thursday through Tuesday
The long term starts out with surface high pressure just off
the mid-atlantic coast and associated fairly pleasant weather.

However as the high moves farther offshore and low pressure
moves into the great lakes, a more typical summertime SW flow
will set up over the region. This in turn will cause increasing
heat and humidity over the forecast area through the end of the
week and into the weekend. At this point it appears that
Saturday may be the most uncomfortable day with heat indices
reaching the mid 90s along the i-95 urban corridor.

Along with more heat and humidity will be gradually increasing
chances for afternoon showers and thunderstorms. For Thursday
and Friday it looks like any precip should remain well to the
northwest of phl. By Saturday an upper-level trof and associated
cold front are forecast to approach the mid-atlantic and also a
surface trof is forecast to develop from eastern pa south
to near the chesapeake bay. Enhanced low-level convergence is
expected to result in more widespread afternoon convection on

For Sunday and beyond the forecast becomes more cloudy, as the
models seem to disagree on whether a surface cold front can push
through our area or whether it will stall out. Given the
uncertainty, the forecast maintains at least a slight chance for
showers t-storms through early next week. Temperatures are
expected to be near or slightly above normal at that time.

Aviation 06z Wednesday through Sunday
The following discussion is for kphl, kpne, kttn, kabe, krdg, kilg,
kmiv, kacy and surrounding areas.

Through today... .Vfr. Few or sct clouds AOA 6000 ft. West northwest
wind gust around 15 kts.

Tonight...VFR. Broken cirrus probably arrives toward dawn Thursday.

Light southwest wind.


Thursday and Friday...VFR conditions expected. Southwest winds
gusting up to 20 kt in the afternoon both days.

Saturday and Sunday... MostlyVFR conditions but lower at times
in scattered mainly afternoon showers and thunderstorms.

Sca issued around 140 am for de bay early this morning where
widespread gusts 25-30 kt. These gusts should diminish toward

Otherwise, no headlines through tonight. Northwest wind gust
15-20 kt at times during the daylight hours becomes south to
southwest late this afternoon and continues tonight. Gusts to 25
kt possible late this afternoon nnj waters.


Thursday and Friday... SCA conditions may develop Thursday afternoon
and continue into Friday due to increasing SW winds and building

Saturday and Sunday... Winds and seas are expected to be somewhat
below SCA levels.

Rip currents... The forecast is for a low risk of rip currents
for Wednesday. However, southwest winds will increase to around
15 kts with higher gusts by late afternoon. With a 9-second
period from a southeasterly direction, this may increase the rip
current risk level, especially on the new jersey coast.

At 5 am: we will finish off the marginally warmer than normal
month of june temperature assessment (except kmpo).

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. It is not checked for accuracy either by anyone at 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.
