Synopsis
A cold front will cross the middle atlantic region this afternoon.

It will be followed by high pressure from the ohio valley which will
be across the area through Friday. Another low pressure system and
cold front will affect our area Friday night and Saturday. More high
pressure will move in for the end of the weekend and into early next
week.

Near term until 6 pm this evening
Cold front is expected to arrive later today. Pressure gradient,
especially behind the front will increase significantly. As a
result, expect gusty conditions and strong cold air advection.

One thing we are not expecting much of with this front is
precipitation. Dew points have dropped into the 30s and 40s across
the region after the cold front from 2 nights ago. There will not be
any significant moisture advection today ahead of the front. Thus,
precipitation, if any, will be limited. Have kept only a slight
chance mention across the southern poconos and NW nj.

Short term 6 pm this evening through 6 am Thursday
Behind the front, expect continued dry and cold air advection
overnight. Consequently, we could see the first freeze of the season
for some of our area. There are however a few unknowns that could
have an impact on how widespread the freeze will be. First of all,
winds are not expected to decouple much overnight, but rather should
remain near or above 10 mph. As a result, we likely won't see much
in the way of a frost. However, this could also limit radiational
cooling. Secondly, if mid level clouds that are expected this
afternoon with the front are slower to clear out, that could also
limit radiational cooling.

Freezing conditions look to be most likely in the southern poconos
where we have issued a freeze warning. For far NW nj, confidence is
lower, so have issued a freeze watch for sussex county. For the rest
of NW nj, lehigh valley, and berks county, we will likely see lows
in the mid 30s, but are not planning any frost advisory at this time
as the winds should preclude the development of frost.

For areas along and southeast of the i95 corridor, expect lows from
the mid 30s to lower 40s.

Long term Thursday through Tuesday
Thursday thru Friday... Mostly fair this period with a ridge of
high pressure affecting the region. Some gusty winds early
Thursday will diminish by afternoon. Temperatures well below
normal Thu then a little below normal for Friday. Increasing
clouds are expected later Friday.

Friday night and Saturday... The wettest part of the long term
with a low pressure system moving north of the area and a cold
front expected to cross the region. Pops were raised from the
earlier fcst with high chc low likely pops now in the grids.

Temperatures will be close to normal Sat with higher humidity
levels too. The cold front will cross the area during the
afternoon, so showers are possible until after the front passes.

Gusty winds are possible sat, but nothing too serious.

Sunday thru Tuesday... Mostly fair weather is expected this
period, however a couple showers may occur across the northern
counties Mon night and Tuesday. High pressure from the west will
build in Mon and the move offshore tue. Temperatures will be
mostly below normal Sun Mon then rebound back to near normal for
tue.

Normal highs: phl mpo ged : 64 55 66
normal lows : phl mpo ged : 46 34 43

Aviation 08z Wednesday through Sunday
Today...VFR conditions expected. Winds will shift from southwesterly
to westerly to west northwesterly through the day. Gusts around 25
kt or more will be possible, primarily between 15 and 00z. High
confidence.

Tonight...VFR conditions expected. Northwesterly winds will
gradually diminish to near 10 kt overnight. High confidence.

Outlook...

thu thru fri...VFR expected. Gusty NW winds Thu morning.

Fri night sat... Sub-vfr possible with showers. Gusty winds sat.

Sat night Sunday...VFR expected. Gusty winds again Sunday.

Marine
Winds will be increasing, especially through the afternoon with gale
force gusts expected to develop by early this evening on all waters
except the upper delaware bay. There is a chance that gale force
gusts could develop a few hours earlier, but don't have enough
confidence at this time to move up the start time of the gale
warning. Gale force gusts should continue for most, if not all of
the overnight hours. On the upper delaware bay, expect small craft
advisory conditions through out the period.

Outlook...

thu: early gales will settle to SCA conditions then drop below SCA later
Thursday. Fair weather.

Thu night thru fri: sub-sca, but winds increase Fri late
afternoon. Fair.

Fri night thru sat. Showers. SCA conditions expected.

Sat night into Sunday..A continuation of SCA conditions with
some low-end gales possible. Fair weather.

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.
