Rain will gradually sink to the south of PA tonight and Wednesday. The forecast will then be dry for a long stretch. While a strong weather system will develop off the East Coast over the next few days, it will stay far enough off-shore that only light rain is expected over far eastern PA this weekend, and the rest of the state will remain dry into the middle of next week. && Warren- Including the city of Warren 343 PM EDT Tue Sep 22 2026 Tonight Wed Wed Night Thu Cloud Cover Mcldy Pcldy Mclear Mclear Precip Type None None None None Chance Precip (%) 0 0 0 0 Chance of Thunder (%) 0 0 0 0 Temp (24h trend) 47 (-1) 67 (+5) 43 67 RH % (24h trend) 94 (-3) 41 (-31) 91 37 20ftWnd-Val/AM(mph) E 6 G17 Lgt/Var 20ftWnd-Rdg/PM(mph) E 5 G13 E 6 G16 Lgt/Var E 5 Precip Amount 0.00 0.00 0.00 0.00 Precip Duration Precip Begin Precip End Mixing Hgt(ft-agl) 440 3940 430 4110 Transport Wnd (mph) E 10 E 15 E 9 E 10 Vent Rate (kt-ft) 3960 51220 3440 36990 Dispersion 2 5 2 5 DSI 2 2 Sunshine Hours 6 10 Max ADI Early 7 Poor 48 Gen Good 21 Fair 10 Poor Max ADI Late 7 Poor 72 Good 4 Very Poor 10 Poor Max LVORI Early 7 6 4 6 Max LVORI Late 7 1 6 6 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
