Area Forecast Discussion National Weather Service Pittsburgh PA 107 AM EDT Sun Jul 17 2022 .SYNOPSIS... A series of low pressure systems will bring increased shower and thunderstorm chances through Monday night. Hot and humid conditions return by the middle of the week. && .NEAR TERM /THROUGH TODAY/... A weak shortwave, moving southeast in the northwest flow aloft, is interacting with a surface warm front/dewpoint line and sparking showers and some storms near the boundary. Models are not in great agreement overnight, but it does look like this activity will shift eastward overnight. Have increased PoPs overnight and included the mention of thunder. Higher dewpoints will drift northeastward overnight. A warm front will traverse the entire forecast area this morning, placing the region in a high humidity airmass. Once the boundary parks to the north, the flow aloft will become zonal. Then a series of shortwaves will make their way across the Upper Ohio Valley. Timing, location, and intensity of these waves remains uncertain, as models are not in very good agreement. However, there will be a chance for a shower or storm at any time during the day, with the highest probability late this afternoon and evening. The threat for severe weather (in the form of damaging wind) this aftn/eve will be predicated on enough warming to destabilize the region, given shear values will struggle to reach 30kts. This will be difficult as clouds will be plentiful and showers and storms will be around for most of the day. In these scenarios, localized flash flooding is a threat due to the high moisture content in the atmosphere (surface dewpoints in the upper 60s to lower 70s) and the risk for repeated heavy downpours over the same locations. && .SHORT TERM /TONIGHT THROUGH TUESDAY/... Another, more pronounced, trough will slowly slide across the region Monday while a series of shortwaves round its base. The increased jet ascent, continued moist advection ahead of the trough axis, and an approaching cold front will promote another round of showers and storms. Precipitation chances will diminish Monday night with frontal passage and the transition of the trough east. Tuesday looks dry with increased sunshine as high pressure moves south of the area. && .LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/... The region likely will dry out and see temperature rise to about 5 degrees above average under weak NW flow and surface high pressure to the south. The next upper trough and sfc cold front should impact the region mid to late week as its drops out of Alberta, CA toward the upper Great Lakes. Timing of trough/front through the region remains uncertain, but the development of showers and thunderstorms is likely prior to its passage at some point during this period. Synoptic details remain too fuzzy for any discussion of severe/flood threat for the system at this time. && .AVIATION /06Z SUNDAY THROUGH THURSDAY/... Scattered showers and thunderstorms will continue to move across portions of the Upper Ohio Valley tonight. All PBZ terminals with the exception of FKL and DUJ will likely see rain at some point, though likely brief. Lightning is occurring across eastern Ohio with these cells and may likely affect HLG and perhaps LBE, MGW, and AGC overnight.. though considering this a rather low confidence forecast. Ceilings are widely VFR with these cells and vis drops to MVFR/IFR only in the center of the strongest cells. Have included TEMPO groups in most likely time showers/storms will pass. Convective activity will wane towards dawn and be at a minimum through early afternoon. Then scattered to widespread thunderstorms are expected with an approaching low from mid- afternoon through at least dusk. IFR restrictions likely with thunderstorm passage, but then MVFR/IFR likely into the night as plentiful low-level moisture remains without much mixing. Wind will remain light/southerly through the majority of the time, though afternoon thunderstorms will hold strong wind gust potential. .Outlook... Degraded conditions are likely from Sunday evening thunderstorms through much of Monday. Improvement is likely into midweek. && .PBZ WATCHES/WARNINGS/ADVISORIES... PA...None. OH...None. WV...None. &&

Hazardous weather is not expected at this time. .DAYS TWO THROUGH SEVEN...Sunday through Friday. Dependent upon enough heating, there is a conditional threat for isolated thunderstorms capable of producing damaging wind Sunday afternoon and evening. Periods of showers and thunderstorms Sunday into Monday may produce heavy rain. Localized flooding, with a higher likelihood in urban and poor drainage areas, could develop if heavy rain falls for a long enough period. .SPOTTER INFORMATION STATEMENT...
