Synopsis
High pressure weakens and moves farther into the northern
atlantic well away from the region today. A warm front will
approach from the south today and move across tonight. A cold
front will then move across Wednesday into Wednesday night. High
pressure builds in from the west Wednesday night through
Thursday. The high moves off the northeast coast Friday and
remains through the weekend. The high moves east Monday as a
weak cold front approaches.

Near term through tonight
The warm front and better forcing remains well to the west,
across southwestern pennsylvania into the central appalachians,
with a few showers ahead of the front. Updated the
probabilities, lowering and delaying the onset of precipitation
early this morning. Also updated the temperatures and dew
points for current conditions and trends.

In the mid levels, a trough approaches from the west, but
lifting farther north as it moves closer to the local area.

The region will have SE flow today with high pressure weakening
and drifting well northeast of the region, allowing for flow to
reorient with approach of a warm front to the west. Expecting
clouds to stay abundant especially along coast. Gmos was used for
max temperatures, taking more from the the cooler side of
guidance. Chances for showers slowly increase during the day,
but may have some initial drizzle before rain showers move in.

There will be a moderate risk of rip currents at the atlantic
ocean beaches today.

Short term Wednesday
The trough moves in with greater height falls entering the
local region tonight and the jet streak in the upper levels
will be approaching near the base of the trough.

A warm front moves in at the surface. Forecast has this front
moving across the region overnight into early Wednesday.

The humidity will be greater tonight with the 1000-850 mb
mixing ratio increasing 2-3 g kg. Further evidence of this will
be the precipitable waters increasing to 2 to 2.1 inches. Min
temperatures likewise will remarkably warmer than the last few
nights, ranging from the upper 60s to lower 70s using the ecs.

The showers will become quite numerous tonight with a chance of
thunderstorms as well. Instability will be increasing and some
low level wind shear will be present, making for potentially
some stronger thunderstorms. There will be a limit to the
instability and lapse rates do not appear too steep.

More height falls at about the same rate continue during the
day Wednesday. The upper level jet streak moves across the
region. At the surface, the cold front will move across the
region from west to east by late in the day. Expect some showers
and thunderstorms, mainly scattered during the day.

Highs Wednesday were a blend of nam12 ecs with a cooler
solution considering the showers and thunderstorms around the
region.

The risk for rip currents at the atlantic ocean beaches for
Wednesday will be moderate.

Long term Wednesday night through Monday
A surface cold front will be exiting to the east of the forecast
area at the very beginning of Wednesday night, and will have
probabilities just for the eastern ocean waters until around 00z
Thursday. The associated mid and upper longwave northern stream
trough will be slow to move east of the area and may delay the cold
frontal passage. With the slow passage of the upper trough clearing
will be slow.

Then an upper ridge moves through the area Thursday night through
Friday night, then slows as the subtropical bermuda high sets up
once again for the weekend. A weak surface trough develops Sunday
afternoon as a weakening upper trough moves into the ridge. Will
leave the area dry at this time with little upper support for
convection. However, the surface trough may become the focus for
isolated afternoon thunderstorms.

With the shortwave trough moving into the ridge Sunday into Monday
the flow becomes more zonal at all levels, and both temperatures and
dew points are forecast to increase. Another surface trough will
develop Monday and with increased surface instability, and
increasing lapse rates, will have slight chance probabilities for
thunderstorms across the interior.

Aviation 11z Tuesday through Saturday
Weak high pressure moves northward as a warm front approaches
from the south today and moves across the area tonight.

Generally looking atVFR conditions today, but can not rule out
some MVFR cigs. Bkn or ovc CIGS around 4-5kft for much of the
day today, however there could be some MVFR CIGS that move in
earlier than forecast. Then, around 22z-00z, CIGS fall to MVFR
and remain down overnight as a warm front approaches. Rain
chance also increase tonight. Ifr CIGS possible after 05z. There
is also a chance of thunder, but timing and placement of any
convection too low to include in the TAF at this time.

A light easterly flow can be expected this morning. By late
morning early afternoon winds will gradually shift towards the
se as a warm front approaches. Speeds this afternoon will remain
below 10kt. Winds become more southerly after 06z, once the
front starts to lift north across the region.

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.
