Activity is beginning to show up on radar over eastern Mississippi late this morning.

They are approaching the Alabama border counties of Lamar, Pickens and Sumter Counties.

Temperatures are passing the 90 degree mark at most locations. They will end up in the middle and upper 90s this afternoon.

Storms will be on the strong side this afternoon across the area, with lots of heat and humidity in place. Storms will produce very heavy rainfall over a short period of time, potentially severe wind gusts, some small hail and lots of dangerous lightning.

Take cover in a substantial shelter if a storm forms near you.
