209 PM EDT Thu Apr 17 2025
.Discussion...
Dry conditions and a warming trend continue through Friday. Deep
mixing will foster wind gusts in the 25 to 35 MPH range during the
afternoon. Minimum relative humidity will improve slightly as
compared to today, but still will be in the 30 to 40 percent range
across much of the region. Thus, some fire weather concerns may
exist tomorrow afternoon. This will not be the case by Saturday.
Shower and thunderstorm chances return this weekend as a cold
front approaches and wavers in the area.
