Synopsis
Following a few lingering showers over the south and east this
morning, dry and seasonable weather can be expected for the
remainder of the week.

Near term until 6 pm this evening
Updated at 720 am to tweak pops according to radar trends. Showers
have edged a bit further east and have reduced rain chances a bit
across the southeast to account for this. With the upper trough
stalling over the region today, still anticipate a few showers to
refire along the ridges this afternoon in shallow instability. Rest
of forecast on track for now.

Previous discussion...

upper trough will stall over the region today. This halt to the
eastward progress will be due to a shortwave which will dive south
from the northern great lakes this afternoon, and cause the trough to
deepen. I think the main affect for the area will be a slowing of
the eradication of the cloud cover and continuing the risk for
isolated to scattered showers over the SE ridges.

Short term 6 pm this evening through Thursday
Trough axis finally rotates through the area late tonight. Models are
indicating an area of showers and cloud cover, associated with the
main wave rotating through the trough, diving southward from lower
mi in northern oh this evening. Would expect the showers to dissipate
as they move southward, as they will be encountering a much drier
atmosphere. However, we will likely see some increase in cloud cover
overnight, as the wave digs southward toward the trough axis.

The area will remain under the influence of the trough on Wednesday.

This should promote at least scattered CU on Wednesday.

Broad surface high pressure will provide a beautiful day on Thursday
with warm temperatures, comfortable conditions and fair weather cu.

Long term Thursday night through Monday
Temperatures will rebound by the weekend as southerly flow returns
and high pressure slides off the atlantic coast. At this point,
ensemble guidance continues to suggest dry weather through at least
Saturday before increasing gulf moisture on the western edge of the
atlantic ridge returning precipitation chances.

Aviation 12z Tuesday through Saturday
MVFR ifr ceilings did indeed develop over southwest pa and northern
wv this morning due to lingering low level moisture and a crossing
trough. Expect these ceilings to lift during the mid to late morning
as low level mixing commences, withVFR conditions expected at all
terminals by 17z or so. Scattered to broken cumulus will persist
through the afternoon, along with northwest wind of around 10 knots.

There is some potential for fog overnight, which will be assessed for
future TAF issuances.

Outlook
PrevailingVFR expected for much of the week, outside of any morning
fog.

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.
