Rain, Some Thunder Across Central Alabama, Severe Storms Moving Across Tennessee Valley; More Strong Storms Later Today

| June 23, 2018 @ 10:46 am

The showers and storms that moved through the Birmingham area earlier have weakened into an area of moderate to heavy rain moving through Talladega, Clay, Coosa, and Tallapoosa Counties.

Moderate rain still covers much of Jefferson, St. Clair, and western Calhoun Counties.

Storms have strengthened in the past few minutes over Walker County. Lots of lightning and thunder around Jasper right now. These storms will push eastward, affecting southern Cullman, southwestern Blount and northern Jefferson Counties around Hanceville, The Colony Hayden, and Warrior. They are not severe and are not expected to be, but will have heavy rain, lightning, and gusty winds.

There are severe thunderstorms over Northwest Alabama. The NWS in Huntsville maintains severe thunderstorm warnings for parts of Colbert, Franklin, Lauderdale and Lawrence Counties. The latest warnings are on the blog.

This is for the MCV or mesoscale convective vortex that has moved rapidly from Memphis to Muscle Shoals in less than 5 hours this morning. Damaging winds are the main threat with this system as it pushes through the Tennessee Valley through the rest of the morning.

There are signs that there will be additional shower and thunderstorm development this afternoon in the I-22/US-280 Corridor from Jasper to Birmingham to Alex City around 2-3 p.m. this afternoon. It will not be widespread or especially heavy.

But it does appear that another complex of storms could develop and push across Central Alabama from west to east in the 5-10 p.m. time frame. The system should weaken after crossing I-65. These storms will be associated with an area of high moisture and strong instability, so severe weather is possible along with heavy rain and dangerous lightning. We weather aware the rest of the day.

A slight risk severe weather outlook is posted by the SPC through the day and into the overnight for the northern half of Alabama.
