Area Forecast Discussion National Weather Service Pittsburgh PA 526 PM EDT Wed Aug 12 2020

SYNOPSIS. Warm, humid weather will continue through the week, with a daily chance for afternoon showers and thunderstorms, mainly south of Pittsburgh.

NEAR TERM /UNTIL 6 AM THURSDAY MORNING/. Radar shows a few showers/storms have initiated in the high terrain in the Allegheny Mountains of Tucker, Preston, and Garrett counties and in near vicinity of a quasi-stationary frontal boundary. Mesoanalysis shows MLCAPE in the vicinity of 1000 J/kg due to diurnal destabilization of the warm, moist boundary layer underneath modest mid-level lapse rates. With lack of deep-layer shear, pulse- storm mode should be maintained through dusk. Given lack of storm coverage, especially over the lower elevations, have reduced POPs across the southeast CWA. Storms will diminish later this evening with the loss of heating.

SHORT TERM /6 AM THURSDAY MORNING THROUGH FRIDAY NIGHT/. A similar forecast will continue through Friday as the quasi- stationary front meanders over the mid-Atlantic region. Persistent, weak shortwave troughing will result in daily, diurnally-supported convection with low-level moisture near the aforementioned boundary.

Above average temperature can be expected for the period.

LONG TERM /SATURDAY THROUGH WEDNESDAY/. Showers/storms will become more likely and widespread this weekend as an upper low lifts out of the Mississippi Valley into the Ohio Valley Friday into Saturday. Seasonable temperatures are expected this weekend. Frontal passage is progged on Monday, with high pressure and drier/cooler weather building into the region by Tuesday.

AVIATION /22Z WEDNESDAY THROUGH MONDAY/. VFR will remain at all terminals overnight, with sufficient cloud cover overnight to prevent the development of widespread fog Thursday morning. Brief restrictions will be possible if isolated showers and thunderstorms develop near any terminals Thursday afternoon.

Outlook. Restrictions will be possible as widespread precipitation is likely for the weekend.

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.
