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 storms will continue Wednesday and Thursday. 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 319 AM EDT Wed Jun 10 2026 Today Tonight Thu Cloud Cover Mcldy Pcldy Mcldy Precip Type Tstms Tstms Tstms Chance Precip (%) 70 50 70 Chance of Thunder (%) 50 50 50 Temp (24h trend) 83 (+2) 68 (+3) 87 RH % (24h trend) 64 (-6) 94 (-2) 61 20ftWnd-Val/AM(mph) SW 5 G13 SW 5 G14 20ftWnd-Rdg/PM(mph) SW 6 G15 Lgt/Var W 7 G16 Precip Amount 0.15 0.07 0.13 Precip Duration 5 2 6 Precip Begin 6 AM Continuing Continuing Precip End Continuing Continuing 6 PM Mixing Hgt(ft-agl) 3360 450 4710 Transport Wnd (mph) W 18 SW 9 W 18 Vent Rate (kt-ft) 53760 3600 75360 Dispersion 5 2 5 DSI 2 2 Sunshine Hours 5 6 Max ADI Early 25 Fair 57 Gen Good 67 Good Max ADI Late 71 Good 8 Poor 91 Good Max LVORI Early 7 6 6 Max LVORI Late 3 6 1 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
