**Heat Advisory for our area until 9 pm**

While the temperatures themselves haven't been too hot, we are making up for it with absurdly high humidity levels and the resultant 100°F or higher heat index value. The heat will continue into Tuesday, though the humidity may be a little lower as a cold front changes our winds to northwest. We're already back below average on Wednesday through Friday, as morning lows could dip into the upper 50s. There's a slight chance of a storm Thursday, and a better chance on Friday. Stay cool!
