 Taking a look at the four things you need to know. Heat advisory is in effect now through Thursday night because we're going to see more upper 90s and 100s. Dry lightning expected Wednesday, which has us under a weather alert day. We want you to be aware with dry thunderstorm activity and the opportunity or the chance for seeing, again, some lightning-caused fires in some of our forested areas. It's going to be the entire region. It's all day Wednesday, but really for us, it looks to be Wednesday afternoon and Wednesday evening.
