An Update on the Alabama Weather Situation Just Before 6 p.m.

SPECIAL NOTE AT 601 PM
Keep an eye on the storm near Winfield in Marion County. It is lifting northeastward and will likely intensify as it moves across Winston and into Cullman county.

ORIGINAL POST
Severe storms are over Northwest Alabama at this hour.

A tornadic storm is just east of Russellville. It shows a strong tornado. A tornado warning was just issued for parts of Franklin and Lawrence Counties. This storm will move near or just south of Moulton and will pass near Hartselle, Priceville or Falkville depending on which directions it takes. The storms should start eventually turning more east-southeast along the warm front, but for now they are moving east or east-northeast.

The warm front extends along the Tennessee River between Florence and Decatur and turns southeast over Marshall and DeKalb Counties. So don’t let your guard down to the east and east-southeast.

The line of storms extends as far south as Okolona, but it having trouble forming any further south so far. It remains to be seen whether it can develop further south.

A couple of severe thunderstorm warnings are in effect for Itawamba County just west of Marion County Alabama. The severe storm near Fulton will pass near Hodges, Hackleburg and Phil Campbell.

We will have to watch the cell near Okolona. It is moving into an area of highest instability and low-level shear. The significant tornado parameter is over 6 over parts of Marion and northern Lamar Counties.

Over the rest of North Alabama, there are showers near Fort Payne in Northeast Alabama, but everything else is quiet for now.

The HRRR seems to have a good handle on the storms for now. They will pass through Marion, Winston, Lawrence, Morgan, Cullman, Blount, Marshall, Etowah, DeKalb, Cherokee as well as Calhoun and Cleburne Counties.

Additional storms may form to the north over Limestone, Madison, and Jackson Counties. They will likely become severe as well

To the south, it remains to be seen whether storms can fire up far enough south to affect Tuscaloosa and Birmingham and areas south. For now, the HRRR says no. The 3 km NAM is more bullish on the idea.

If they do, they will be tapping some very volatile air.

We will be watching.
