Heat and humidity are expected to continue to increase through the end of the week. Heat index values will reach into the upper 90s to near 100F across much of southeastern Pennsylvania Thursday and Friday. Multiple rounds of showers and thunderstorms will continue through Friday. A few storms could produce damaging winds, but the main impact will be some beneficial rainfall for much of the area. Only brief breaks in the chance for rain exist through Friday. A cold front pushing through on Friday/Friday night will force widespread showers and storms and perhaps severe thunderstorms. Relatively drier air is expected this weekend, with relative humidities diving back down into the 30-40% range across much of central Pennsylvania for Sat and Sun. && Warren- Including the city of Warren 252 PM EDT Wed Jun 10 2026 Tonight Thu Thu Night Fri Cloud Cover Pcldy Mcldy Pcldy Mcldy Precip Type Tstms Tstms Tstms Tstms Chance Precip (%) 60 70 40 90 Chance of Thunder (%) 50 50 20 50 Temp (24h trend) 67 (0) 87 (+3) 66 83 RH % (24h trend) 96 (0) 55 (-1) 100 46 20ftWnd-Val/AM(mph) SW 5 G14 SW 6 G16 20ftWnd-Rdg/PM(mph) Lgt/Var W 7 G16 Lgt/Var W 6 G16 Precip Amount 0.07 0.18 0.08 0.09 Precip Duration 2 4 2 7 Precip Begin 10 PM Continuing Continuing Continuing Precip End Continuing Continuing Continuing 6 PM Mixing Hgt(ft-agl) 440 4030 470 3550 Transport Wnd (mph) SW 8 W 20 SW 9 W 18 Vent Rate (kt-ft) 3080 68510 3760 56800 Dispersion 2 5 2 5 DSI Sunshine Hours 5 6 Max ADI Early 60 Gen Good 52 Gen Good 44 Gen Good 41 Gen Good Max ADI Late 8 Poor 81 Good 8 Poor 72 Good Max LVORI Early 6 5 6 5 Max LVORI Late 6 1 6 2 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
