Area Forecast Discussion National Weather Service Pittsburgh PA 741 PM EDT Tue Jul 7 2020

SYNOPSIS. Well above average temperatures and scattered showers and thunderstorms mainly during the afternoon and early evening will persist through the week.

NEAR TERM /UNTIL 6 AM WEDNESDAY MORNING/. Showers and thunderstorms should continue to gradually diminish this evening as instability wanes, and a weak shortwave trough begins to exit the region. Dry weather is then expected overnight, though with the recent rain, patchy fog and stratus are expected. Lows are expected to range from 5 to 10 degrees above average.

SHORT TERM /6 AM WEDNESDAY MORNING THROUGH THURSDAY NIGHT/. Ridging will build on Wednesday leaving the best chance for showers/storms over the ridges during the afternoon. High temperatures in the low 90s will persist.

Higher pressure returns on Thursday as the upper ridge axis crosses the region. This will lower, but not eliminate, afternoon convection chances. Have maintained slight chance thunder for much of the area, with higher chance PoPs across the WV/MD ridges.

LONG TERM /FRIDAY THROUGH TUESDAY/. The long term period marks an eventual transition to cooler temperatures and more unsettled weather as upper troughing digs across the Great Lakes and Upper Ohio Valley into the weekend. Friday/Saturday will feature better organized and more widespread rain chances with crossing shortwaves in advance of a frontal passage on Saturday.

At least one of these weekend days may need to be monitored for a severe or flash flood threat given the abundant moisture present ahead of the approaching disturbances.

Temperatures will moderate back towards average through the weekend into early next week, with highs in the lower 80s by Sun/Mon.

AVIATION /00Z WEDNESDAY THROUGH SUNDAY/. Showers and thunderstorms should continue to diminish this eve as instability wanes and a weak shortwave trough exits. MVFR to IFR fog and stratus is expected late tonight, especially for ports that saw rain today, with the low lvl moisture in place. This should dissipate after sunrise Wed with VFR expected, though another, weaker shortwave trough and daytime destabilization should result in sct aftn tstms.

Outlook. VFR is expected to prevail, with exceptions for daily sct aftn and eve convection.

CLIMATE. Based on the 30-year climatological average, here is the "normal" number of 90-degree days per year at each of the local climatic sites:

Pittsburgh: 6.9 days Morgantown: 8.0 days Wheeling: 5.0 days Zanesville: 10.0 days Dubois: 1.0 day

90F+ temperatures are still forecast through Friday, barring interference from well-timing thunderstorms. Based on historical stretches of 90F days, here is a summary of the most-recent such stretches at each site:

Pittsburgh (7/3-7/10/2020): prior 8-day stretch ended 8/20/1995 Morgantown (7/2-7/10/2020): prior 9-day stretch ended 8/4/1995 Wheeling (7/4-7/10/2020): prior 7-day stretch ended 7/27/2016 Zanesville (7/4-7/10/2020): prior 7-day stretch ended 7/8/2012 Dubois (7/5-7/10/2020): would be longest 90F stretch at DUJ.

Dubois most recently had a 5-day stretch of 90F days ending 7/23/2011. Dubois also is the site with the greatest potential variability in the forecast maximum during this forecast period, and therefore the most likely not to reach 90F on any given day.

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.
