Generally fair and dry weather will persist across the bulk of Pennsylvania through this last weekend of July. A weak trough of low pressure and tongue of low-level moisture streaming north ahead of it will create a few isolated showers or a thunderstorm along the western edge of the Allegheny Mountains this afternoon and evening. Lower dewpoints and pockets of minRH in the low to mid 30s will occur across the Susquehanna Valley and points east this afternoon. A gradual increase in the coverage of showers and thunderstorms and humidity will occur across the Western half of the Commonwealth Sunday afternoon and will peak Monday afternoon and Tuesday as a warm/cold front tandem moves east across the region. && Warren- Including the city of Warren 343 AM EDT Sat Jul 25 2026 Today Tonight Sun Cloud Cover Pcldy Pcldy Pcldy Precip Type Tstms Tstms Tstms Chance Precip (%) 20 30 30 Chance of Thunder (%) 20 30 30 Temp (24h trend) 79 (+1) 56 (+2) 82 RH % (24h trend) 55 (+14) 100 (+14) 52 20ftWnd-Val/AM(mph) Lgt/Var Lgt/Var 20ftWnd-Rdg/PM(mph) Lgt/Var Lgt/Var Lgt/Var Precip Amount 0.03 0.01 0.03 Precip Duration 1 1 1 Precip Begin 8 AM Continuing 2 PM Precip End Continuing 11 PM Continuing Mixing Hgt(ft-agl) 3300 400 4760 Transport Wnd (mph) S 12 SW 5 W 7 Vent Rate (kt-ft) 33000 1600 28560 Dispersion 5 1 5 DSI 2 2 Sunshine Hours 7 7 Max ADI Early 29 Fair 5 Very Poor 21 Fair Max ADI Late 42 Gen Good 2 Very Poor 40 Fair Max LVORI Early 4 7 9 Max LVORI Late 2 9 2 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
