Southside will likely be the exception, as our front meanders nearby. This will also be a focal point for a few storms Thursday afternoon. The better chance, at the moment, appears to be in areas along and south of US 460 during the afternoon and evening. That timing may change.

This same high pressure, with clockwise wind around it, will direct a plume of Saharan dust into the region by late Saturday and Sunday.

The chance for storms is fairly scattered by Sunday. If it were to storm near you, a portion of dust could actually be brought down to the surface within the raindrops.
