A weak and dry cold front will drift Southeast from the Lower Great Lakes, bringing some clouds to the Northwest and North- Central Mountains of Pennsylvania this morning. Otherwise, high pressure will dominate our weather through the rest of this week with a relatively light northerly wind for today and Wednesday. Another cold front will push through the Commonwealth Wednesday night into Thursday followed by a moderately gusty northerly wind, enhancing the risk of fire spread. Min RH values this afternoon and again on Wednesday will be in the 30 to 40 percent range. && Warren- Including the city of Warren 333 AM EDT Tue Oct 20 2026 Today Tonight Wed Cloud Cover Mclear Clear Mclear Precip Type None None None Chance Precip (%) 0 0 0 Chance of Thunder (%) 0 0 0 Temp (24h trend) 67 (0) 31 (-5) 66 RH % (24h trend) 38 (+15) 100 (+1) 29 20ftWnd-Val/AM(mph) Lgt/Var Lgt/Var 20ftWnd-Rdg/PM(mph) Lgt/Var Lgt/Var Lgt/Var Precip Amount 0.00 0.00 0.00 Precip Duration Precip Begin Precip End Mixing Hgt(ft-agl) 3380 400 2490 Transport Wnd (mph) NE 13 E 8 N 7 Vent Rate (kt-ft) 37180 2800 14940 Dispersion 5 2 5 DSI 1 1 Sunshine Hours 9 10 Max ADI Early 17 Gen Poor 5 Very Poor 8 Poor Max ADI Late 49 Gen Good 4 Very Poor 20 Gen Poor Max LVORI Early 7 6 8 Max LVORI Late 2 9 2 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
