409 FXUS61 KPBZ 291754 AFDPBZ Area Forecast Discussion National Weather Service Pittsburgh PA 154 PM EDT FRI JUL 29 2016 .SYNOPSIS... A series of weather disturbances will keep showers in the forecast through the weekend. && .NEAR TERM /UNTIL 6 PM THIS EVENING/... Stratus has largely lifted into broken cumulus south of a boundary that is laying basically along I-80. A weak wave will shift to the southeast toward evening. Hi-res/HRRR guidance all develop convection in SE Michigan by afternoon and intensify it a bit as it interacts with the lake breeze along Lake Erie by later afternoon. It continues southeast toward our area during the evening, likely weakening as it does so. Fries && .SHORT TERM /6 PM THIS EVENING THROUGH SUNDAY/... Very little change to the overall pattern, with zonal flow aloft and shortwaves riding eastward in the flow. The risk for showers and storms will continue through the entire weekend, with best timing linked to the passage of aforementioned waves. Continued humid with near seasonal daytime temperatures. && .LONG TERM /SUNDAY NIGHT THROUGH THURSDAY/... Appears to be enough low level moisture for low chance pops in the ridges Monday, otherwise a weak bubble of surface high pressure looks to bring warm temperatures with little chance for showers Tuesday and Wednesday. A frontal boundary may get close enough for chance POPs on Thursday. A modified Superblend was used for the extended period. && .AVIATION /18Z FRIDAY THROUGH WEDNESDAY/...
-- Changed Discussion --
VFR conditions this afternoon with minimal thundershower chances. Exception being KFKL and KDUJ where some MVFR conditions and TS possible. given low level moisture tonight expect a return to some fog and stratus...but not as dense and as long lasting as this mornign. Precipitation chances will increase for saturday ahead of an approaching shortwave. .OUTLOOK /FRIDAY NIGHT THROUGH TUESDAY/... Broad upper troughing should maintain periodic shower and thunderstorm restriction potential through Monday.
