The heat is on in Mississippi with heat index values into the triple digits for most of us Friday. A heat advisory has been issued by the National Weather Service from the southern edge of northern Mississippi all the way to the Gulf Coast.

There’s also another chance for dangerous flash flooding in Mississippi Friday. A Level 1 threat has been issued for much of central Mississippi from near Greenwood to the Alabama state line and down to Meridian. Up to three inches of rain are expected Friday afternoon.

It looks like we’re about to have another tropical system in the Atlantic Ocean. There’s a 70 percent chance of development for this cluster of storms. Even if it does develop, it’s far enough north that we don’t have to worry about it along the Gulf.
