Clouds will increase tonight with isolated to scattered showers and a few possible thunderstorms streaming east-northeast over western and central PA. Tuesday will be the warmest day of the week with increasing odds for rain expanding from northwest to southeast through Tuesday night into midweek. Recent coordination with DCNR fire partners indicates that the Spring fire season is largely over for areas to the south of I80 due to a very warm April and early greenup. While it will be breezy Tuesday afternoon, minRH in the 40-50% range across the northern tier which would not be favorable for an elevated risk of wildfire spread. && Warren- Including the city of Warren 251 PM EDT Mon May 4 2026 Tonight Tue Tue Night Wed Cloud Cover Pcldy Mcldy Cloudy Mcldy Precip Type Tstms Tstms Tstms Showers Chance Precip (%) 70 70 100 80 Chance of Thunder (%) 50 50 50 0 Temp (24h trend) 52 (+8) 68 (-1) 43 54 RH % (24h trend) 93 (+25) 51 (+16) 100 69 20ftWnd-Val/AM(mph) SW 9 G23 Lgt/Var 20ftWnd-Rdg/PM(mph) SW 7 G22 SW 9 G23 Lgt/Var Lgt/Var Precip Amount 0.16 0.21 0.47 0.45 Precip Duration 5 5 12 9 Precip Begin 6 PM Continuing Continuing Continuing Precip End Continuing Continuing Continuing Continuing Mixing Hgt(ft-agl) 630 3550 570 1660 Transport Wnd (mph) SW 14 SW 29 NE 5 N 8 Vent Rate (kt-ft) 7560 88750 2280 11620 Dispersion 3 5 1 4 DSI 2 1 Sunshine Hours 2 2 Max ADI Early 28 Fair 65 Good 13 Gen Poor 10 Poor Max ADI Late 15 Gen Poor 74 Good 4 Very Poor 15 Gen Poor Max LVORI Early 4 5 7 9 Max LVORI Late 5 1 8 5 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
