Multiple rounds of showers and storms will continue through the rest of the week and into the weekend, especially across the northwest where rainfall totals may exceed 1-2 inches between today and tomorrow. Some storms may be severe with damaging winds on Wednesday. However, locations in south-central PA will see a continued stretch of dry weather, particularly if showers and thunderstorms weaken or dissipate before making it southward into this area each day. Min RH values are expected to dip into the 30s to lower 40s this afternoon. Thursday is looking to be the driest day with min RH in the 20s and 30s. Combined with the low RH values, wind gusts above 20 mph Thursday afternoon may result in an elevated risk of wildfire spread. && Warren- Including the city of Warren 1018 AM EDT Wed Apr 15 2026 Today Tonight Thu Cloud Cover Mcldy Mcldy Mcldy Precip Type Tstms Tstms Tstms Chance Precip (%) 90 80 70 Chance of Thunder (%) 70 50 20 Temp (24h trend) 76 (+3) 59 (+2) 76 RH % (24h trend) 64 (+1) 98 (-1) 55 20ftWnd-Val/AM(mph) SW 7 G17 SW 5 G17 20ftWnd-Rdg/PM(mph) SW 7 G19 SW 5 G13 SW 7 G22 Precip Amount 0.28 0.36 0.13 Precip Duration 5 9 5 Precip Begin 6 AM Continuing Continuing Precip End Continuing Continuing Continuing Mixing Hgt(ft-agl) 3060 420 4810 Transport Wnd (mph) SW 20 SW 10 SW 26 Vent Rate (kt-ft) 52020 3780 110630 Dispersion 5 2 5 DSI 2 2 Sunshine Hours 3 3 Max ADI Early 8 Poor 8 Poor 8 Poor Max ADI Late Very Poor 8 Poor Very Poor Max LVORI Early 9 6 8 Max LVORI Late 4 6 3 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
