Two distinct boundaries will be located over Pennsylvania during the upcoming 30 hours. The first is a stationary front located from Northwestern PA to the South-Central part of the state. the second will be a slow-moving backdoor cold front across from the Endless Mountains of Northeastern PA to the Lower Delaware Valley. These two boundaries will help to focus periods of rain with progressively cooler air from east to west across the state. The heaviest rain will likely be across the Northern Third of Pennsylvania. It will be overcast tonight and much cooler on Saturday with periods of rain ending early Sunday. && Warren- Including the city of Warren 247 PM EDT Fri Apr 24 2026 Tonight Sat Sat Night Sun Cloud Cover Mcldy Mcldy Mcldy Pcldy Precip Type Tstms Tstms Showers None Chance Precip (%) 80 90 40 0 Chance of Thunder (%) 50 20 0 0 Temp (24h trend) 48 (0) 59 (-16) 40 64 RH % (24h trend) 100 (+34) 68 (+23) 96 43 20ftWnd-Val/AM(mph) Lgt/Var Lgt/Var 20ftWnd-Rdg/PM(mph) Lgt/Var SW 5 G13 Lgt/Var Lgt/Var Precip Amount 0.35 0.37 0.07 0.00 Precip Duration 6 11 3 Precip Begin 6 PM Continuing Continuing Precip End Continuing Continuing 6 AM Mixing Hgt(ft-agl) 350 1550 1120 4630 Transport Wnd (mph) E 8 NW 10 NE 12 E 9 Vent Rate (kt-ft) 2450 13950 11200 37040 Dispersion 1 5 3 5 DSI 1 2 Sunshine Hours 2 7 Max ADI Early 5 Very Poor 17 Gen Poor 9 Poor 49 Gen Good Max ADI Late 7 Poor 19 Gen Poor 10 Poor 52 Gen Good Max LVORI Early 4 7 6 4 Max LVORI Late 6 4 6 1 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
