Synopsis
Strong to severe thunderstorms remain possible this afternoon
and evening ahead of a front. After a relatively quiet Friday, a
wet weekend appears likely, perhaps with more strong storms
Saturday.

Near term through Friday
A weak boundary has sagged into the area without any further
impetus to further perpetuate its continued southerly travels.

Thus, it will linger over the area, providing a conduit for
continued convective debris to float down through the night.

While it does remain overhead, instability has really diminished
owing to a few factors: the diurnal, an unfavorable upper level
thermal environment, and a lack of synoptic scale support. Thus,
once the ongoing weak convection in the southeastern portions of
the area fades, no additional rainfall is anticipated for the
remainder of the night.

Convective debris and a soupy boundary layer should keep
temperatures up well above climo at all sites overnight. Fries

Short term Friday night through Sunday
Will hang on to some slight chance pops on Friday across the
southern counties as there is still a touch of uncertainty just
how far south the boundary will be pushed by tonight's
activity. The models also look a touch slower with the next wave
in the northwest flow pattern, and have backed off precip
chances a bit here.

The weekend looks wet, as great lakes low pressure passes to the
north, and several shortwaves run down the northwest flow. Flow
over our area turns more zonal by Sunday, which will slow
progression of the associated frontal boundary. Kept likely pops
going through this period with several rounds of rain expected.

Rainfall totals will have to be watched for problematic areas.

Additionally, there appears to be a risk for severe storm
Saturday, especially if some cloud breaks can form, given decent
mid-level flow.

Temperatures will start a slow fall this period, held in check
by the clouds and rain. Minimal changes were made.

Long term Sunday night through Thursday
A general great lakes northeast u.S. Trough will be carved out
by Monday, with this pattern holding into mid-week. Temperatures
will fall back to near or just below normal during this period.

After lingering precipitation Monday, Tuesday and Wednesday
appear dry at this distance. A return to northwest flow may
herald increasing rain chances Thursday.

Aviation 01z Friday through Tuesday
As of 2330z, most lightning has come to an end across the
region, and have removed all mention of thunder in tafs.

Showers will continue to affect terminals from pittsburgh to the
south and east into the evening hours, with diminishing coverage
after midnight. Considering most locations received at least
some rainfall, have added a mention of fog at all TAF sites,
especially considering the last two 12z soundings at pittsburgh
have shown an extremely shallow layer of moisture at the
surface. Added ifr mentions at locations that dropped to those
conditions earlier this morning. Some scattered convection may
occur at zanesville Friday afternoon, but did not have enough
confidence to include in the TAF at this time.

Outlook
Additional rounds of storms are expected through the weekend,
and morning fog is possible as well.

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.
