Temperatures are cruising toward the 90 degree mark in nearly all areas this afternoon with a nice field of puffy cumulus clouds forming across Alabama.

There is some instability across Central Alabama this afternoon, with CAPE values expected to be between 1000 j/kg and 2000 j/kg.

A broad ridge of high pressure in the upper atmosphere over the southern third of the U.S. is in control of our weather for now, so only isolated storms will be able to form today across the central part of the state.

If any do form, they will tap that high instability and could be strong.

A frontal system lies to our north over Missouri, southern Illinois and southern Indiana this afternoon. This front will sag southward to near the Alabama/Tennessee border overnight, where it will likely go stationary. It could trigger a few storms late today or tonight over North Alabama.

Showers and storms will form tomorrow as the front comes south. Some of them could be strong to severe, with damaging winds the main threat. Lightning will be a problem, and heavy rains could be a problem also.

Tropical Storm Arthur was named at noon as it moved into Belize. It is weakening but could become a tropical storm again tomorrow as it moves back over the southwestern Gulf. It is not expected to affect the U.S. However, the region from the southern Gulf back into the northwestern Caribbean will remain on the nervous side this week.
