Area forecast discussion, Jul 11, 3:34 PM EDT, 49 minutes before
Area Forecast Discussion National Weather Service Pittsburgh PA 334 PM EDT Tue Jul 11 2017 .SYNOPSIS... Showers and thunderstorms will continue to plague the region as a series of upper disturbance interact with a meandering frontal boundary. && .NEAR TERM /THROUGH WEDNESDAY/... A quick update was issued to adjust PoPs and other hourly trends. Showers and thunderstorms will continue to blossom this evening as a shortwave (with embedded MCV) emerge from the midwest. That system is pumping abundant moisture into a weak frontal/convergence zone stretching southeastward across Ohio and northern West Virginia. The main problem of the evening will be locally heavy rainfall as that boundary is shunted across areas from around New Philadelphia to near, and north of Morgantown. Rainfall is expected to be enhanced via warm rain processes as warm, moist advection continues into the mid levels. Given those warm mid levels, expect convection to ease with the heating and eastward progress of the supporting disturbance. Wednesday will feature enhanced warmth and continued humidity with warm advection under flat ridging. No change was needed to the temperature forecast about 5 degrees above the averages or the scattered convection prognosis focused near the northward lifting frontal boundary. && .SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/... A dry Wednesday evening is forecast in the warm sector although low pressure tracking across the Great Lakes along a nearly stationary boundary may fire a few showers and storms mainly north of Pittsburgh by Thursday morning. Precipitation is forecast to spread across the entire region Thursday with encroachment of the front. Weak flow/deep layer shear are expected to inhibit the severe threat with that system. Frontal passage is not likely to be decisive and convection chances will linger until a more significant disturbance drives it through on Friday. .LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/... Surface high pressure looks to finally build over the area for the weekend after the projected frontal passage Friday. Another shortwave and front look possible for Sunday, but timing remains uncertain. For now, dry weather is expected Monday with a transition to an upper ridging pattern, which could hold into the middle of next week. && .AVIATION /19Z TUESDAY THROUGH SUNDAY/... Abundant moisture and convection will plague area ports this evening, while residual stratus and fog are possible at sites that receive rainfall and along the northward lifting frontal boundary in the morning. Rainfall is expected to be focused along that boundary, which is forecast to drift acrss the HLG and MGW areas this evening. .OUTLOOK... Periodic restrictions are expected in convection through out the week. && .PBZ WATCHES/WARNINGS/ADVISORIES... MD...None. OH...None. PA...None. WV...None. && 15
