The National Weather Service is monitoring the possibility for severe weather in Alabama over the weekend.

A strong storm system will bring a cold front across the state and generate another round of rain and storms.

This system will also bring back the possibility of tornadoes to Alabama, which has already seen its fair share so far this year (40 statewide, according to the weather service).

Forecasters are cautioning that damaging wind gusts, frequent lightning and heavy rain will all be possible as well.

The timing is still evolving, but as of Thursday night it appeared the risk of tornadoes was increasing for Sunday morning, according to Spinks Megginson of Red Zone.

“Severe weather parameters are increasing for Sunday morning when a vigorous line of strong to severe thunderstorms will move across south Alabama and northwest Florida from west to east,” he said. “There are some model indications that point to this being a line of supercell thunderstorms. That scenario would likely increase the tornado potential, as compared to a classic squall line that is more common around our region. In addition to tornadoes, damaging straight line wind gusts, small hail, and lightning are also likely.”

Megginson said the Storm Prediction Center continues to include the entire region (all of south Alabama and northwest Florida) in its Level 2 (out of 5) risk zone.

The 12-hour window when severe weather will be most likely is from 4 a.m. to 4 p.m. on Sunday with the core window being from 7 a.m. to 2  p.m., he said.
