Synopsis
A warm front is forecast to lift through our region this
evening and overnight. A cold front approaching from the west is
expected to move slowly across eastern pennsylvania,
northeastern maryland, delaware and new jersey on Wednesday.

High pressure is anticipated to follow for Thursday and Friday.

The main center of the high should move out to sea over the
weekend but it is expected to continue influencing our weather
into early next week.

Near term until 6 am Wednesday morning
Warm front currently extends across central pennsylvania
southeastward into delaware and southern new jersey accompanied
by cluster of heavy showers and thunderstorms. This front
connects back to a surface low moving NE across eastern canada.

As we head through tonight, have concerns once again for heavy
rainfall with an associated flash flood threat. The main concern
right now is across eastern pennsylvania where 1-hour flash
flood guidance is around 0.50 inches or less. Heavy rain is
falling from these storms and can easily produce upwards of 2-3
inch per hour rates.

Thinder chances will continue through the next few hours but the
best instability is already waning and lapse rates are weak
across our region. Have reduced the thunder threat through the
overnight hours to a slight chance, removing any mention of
thunder by daybreak.

Showers storms will move out through the predawn hours as the
low tracks into quebec with the cold front right on our doorstep
by morning. It will be a mild, muggy night in the warm sector
with lows generally in the upper 60s to low 70s.

Short term 6 am Wednesday morning through 6 pm Wednesday
Low pressure will move northeast across quebec through the day
with its attendant cold front slowly moving south east across
the forecast area through the day. Also, the upper level trough
will be continuing to linger over the NE CONUS in the system's
wake. As a result, expect considerable cloud cover to persist
across the area with some scattered showers and storms possible.

Highs will generally be in the low to mid 80s except 70s across
the southern poconos. The main change through the day though
will be falling dew points as the front moves across. It will
start out quite muggy but by late day expect dew points in the
low to mid 60s... Much more comfortable in comparison!

Long term Wednesday night through Tuesday
A long wave mid level trough is forecast to be located over
eastern canada and the northeastern states on Wednesday night
and Thursday before it lifts northeastward and away from our
region. The mid level pattern is expected to flatten a bit over
the weekend before some ridging begins over the eastern states
early in the new week.

Surface high pressure is anticipated to be centered in the
middle mississippi river valley on Wednesday night. The high
will build eastward with its center forecast to pass through our
region on Friday before moving out to sea. Dry weather is
expected for Thursday and Friday with noticeably lower humidity
than we've been experiencing. Dew point readings should drop
into the 50s.

The surface high is expected to get absorbed into the large
high over the western north atlantic. The surface flow should
begin to favor the south and southwest resulting in an increase
in heat and humidity during the period from Saturday through
Tuesday. The anticipated rise in humidity levels may bring about
isolated showers and thunderstorms on Monday and Tuesday mainly
during the afternoon and early evening hours.

Daytime highs should favor the upper 70s and lower 80s on
Thursday and Friday, the 80s on Saturday and Sunday, and the
upper 80s and lower 90s on Monday and Tuesday. Overnight lows
should also increase gradually during the period, starting in
the 50s and 60s on Wednesday night and ending in the upper 60s
and lower 70s on Monday night.

storms are expected to push to the north and east through

East southeast winds around 5 to 10 knots will continue through
tonight. Winds will turn more to the south and then southwest
overnight.

Wednesday... MVFR ifr conditions likely in the morning
with conditions lifting to lowVFR by early to mid afternoon.

Scattered showers and thunderstorms with sub-vfr conditions
possible as a cold front shifts offshore. Southwest to west
winds around 10-15 knots with gusts up to 20 to 25 knots through
the afternoon. Winds will turn more to the northwest late in
the TAF period.

Wednesday night and Thursday... MainlyVFR. Northwest wind 5 to
10 knots.

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 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.
