Scattered to numerous light rain showers will gradually shift east this morning as cooler temperatures move in behind a cold front. Northwest winds will gust 20 to 30mph this afternoon as minimum RH values dip into the 30s (and perhaps as low as the mid 20s). Some light snow is possible in the Laurel Highlands and northern mountains tonight and on Monday. Light accumulation is possible at higher elevations. RH values will drop below 30% on Monday and Tuesday. Monday looks breezier than Tuesday, though temperatures will be relatively chilly on Monday (highs between 35 and 50F). Tuesday trends warmer but winds will be lighter. Another batch of light rain on Wednesday will give way to a dry end of the week. Temperatures trend warmer each day through Friday with highs getting back into the 70s to near 80F. && Warren- Including the city of Warren 334 AM EDT Sun Apr 19 2026 Today Tonight Mon Cloud Cover Pcldy Pcldy Pcldy Precip Type Snow Showers Snow Showers None Chance Precip (%) 20 50 0 Chance of Thunder (%) 0 0 0 Temp (24h trend) 47 (-31) 23 (-17) 40 RH % (24h trend) 37 (-5) 84 (-13) 35 20ftWnd-Val/AM(mph) W 7 G19 NW 6 G16 20ftWnd-Rdg/PM(mph) W 10 G21 W 6 G17 NW 7 G16 Precip Amount 0.03 0.04 0.00 Precip Duration 0 2 Precip Begin 6 AM Continuing Precip End Continuing 6 AM Mixing Hgt(ft-agl) 7580 1200 6460 Transport Wnd (mph) W 28 NW 15 NW 18 Vent Rate (kt-ft) 181920 15600 103360 Dispersion 5 3 5 DSI 2 2 Sunshine Hours 4 7 Max ADI Early 12 Poor 85 Good 73 Good Max ADI Late 143 Very Good11 Poor 112 Very Good Max LVORI Early 6 4 4 Max LVORI Late 2 4 1 Remarks: ADI is Atmospheric Dispersion Index by Lavdas.
