Our lengthy string of dry and mild early Autumn weather will continue right through the upcoming weekend with an essentially zero percent chance of measurable rain and very little in the way of cloud cover. Afternoon dewpoints were adjusted slightly lower Sunday (especially across the Central Ridge and Valley Region) based on the location of the surface and upper level high pressure over Eastern PA and observed mixing trends (and similar mixed layer depth) that have occurred over the past few days. && Warren- Including the city of Warren 257 AM EDT Wed Oct 21 2026 Today Tonight Thu Cloud Cover Mclear Mclear Mclear Precip Type None None None Chance Precip (%) 0 0 0 Chance of Thunder (%) 0 0 0 Temp (24h trend) 64 (-2) 31 (-1) 62 RH % (24h trend) 27 (-11) 100 (+1) 47 20ftWnd-Val/AM(mph) Lgt/Var Lgt/Var 20ftWnd-Rdg/PM(mph) Lgt/Var Lgt/Var N 5 G13 Precip Amount 0.00 0.00 0.00 Precip Duration Precip Begin Precip End Mixing Hgt(ft-agl) 2720 370 3280 Transport Wnd (mph) N 6 N 7 N 15 Vent Rate (kt-ft) 13600 2220 42640 Dispersion 5 1 5 DSI 1 1 Sunshine Hours 10 8 Max ADI Early 8 Poor 4 Very Poor 27 Fair Max ADI Late 20 Gen Poor 4 Very Poor 59 Gen Good Max LVORI Early 6 8 8 Max LVORI Late 2 9 1 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
