FNUS71 KRLX 150904 FWSRLX Spot Forecast for Upper Greenbrier North RX...West Virginia Division of Forestry National Weather Service Charleston WV 504 AM EDT Wed Apr 15 2026 Forecast is based on ignition time of 0600 EDT on April 15. If conditions become unrepresentative, contact the National Weather Service. .DISCUSSION... Summer-like weather will continue through the week, with highs in the 80s, which will keep the fire danger high because of minimum afternoon relative humidity percentages around 40s, and breezy conditions with 20-foot wind gusts of 15 to perhaps 20 mph. Showers and storms are most likely with a system Thursday night, and then again with a strong cold front Saturday night. That cold front will bring much cooler air, along with another stretch of mainly dry weather, for the end of the weekend and the start of the next work week. Minimum afternoon relative humidity percentages are expected to be in the 20s for much of the area next Monday and Tuesday. .TODAY... Sky/weather.........Sunny (15-25 percent).
