Synopsis
A scattered shower or storm is possible mainly south and west
of pittsburgh today. Warm and humid conditions will continue
into early next week.

Near term until 6 pm this evening
Increased and extended pops just a bit further eastward than
previous forecast, into the pittsburgh area. 12z kpit sounding
shows little capping in place initially, and instability appears
sufficient to extend slight precipitation chances a bit.

Forecast largely on track otherwise.

Previous discussion...

short wave trough will remain to the west of most of the region
today, stretching from western lake erie southward through
central western ohio and into kentucky. This large scale
ascension and a modestly unstable atmosphere, may be enough to
fire scattered showers and storms this afternoon. Warm mid
levels and subsidence should keep activity suppressed to the
east of the trough. Another warm day with temperatures well
above normal.

Short term 6 pm this evening through Friday
Shortwave will phase out tonight as upper level heights begin to
rise in earnest. Upper level ridging will become even more
firmly entrenched over the ohio valley great lakes through the
end of the week as a deep trough digs over the western u.S..

This will lead to dry weather and further warming through
Friday. Highs in the mid 80s will be common.

Long term Friday night through Tuesday
Little change in the large-scale circulation pattern is expected
during the extended period, with the western trough eastern
ridge setup maintaining, if not strengthening, through early
next week. As a result, a dry and quite warm forecast continues.

With 850mb temps soaring to the 17-19c range, most locations
outside of the ridges will rise well into the 80s.

Aviation 14z Wednesday through Sunday
Fog development has not been very uniform in the valleys even in
areas that have been relatively clear all night. Localized ifr
conditions will be likely through sunup around fkl duj, however
elsewhere restrictions are likely to be more spotty. Regardless,
all areas will beVFR by 13 or 14z with only a few showers
possible this afternoon as a weakening mid-level low moves to
our south. Fries

Outlook
Other than local morning fog, no widespread restrictions
expected through Sun with building ridging.

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors.

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.
