 Fire Weather Planning Forecast

 .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 in the 20s and 30s, and 
 breezy conditions. Mainly afternoon and evening showers and storms 
 are possible each day. Any thunderstorms that do form in interior 
 southeast Ohio this afternoon and evening can become strong to 
 marginally severe. Otherwise, showers and storms are most likely 
 with a system late Thursday through Thursday night, and then again 
 with a strong cold front late Saturday through 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.
