The supercell that has produced a long history of damage and one fatality in Mississippi is moving northeast at about 50 MPH. This storm is isolated and it is riding the northern edge of the higher-dewpoint air (higher instability).

That unstable air is moving north; we may have to deal with this storm between 3 and 5 PM in Winston, Lawrence, Morgan and/or Cullman Counties. That’s obviously a long way off, but it’s something we’re watching closely.

Brandon Chambers April 11, 20132:08 pm

Radar at 2:00PM.. Heavy storms producing lightning, heavy rain, and occasional gusty winds. Very slow eastward movement. 15-20mph. No active warnings for the WHNT viewing area.

Jason Simpson April 11, 20132:17 pm

Severe weather threat ending soon for The Shoals area; temperatures are dropping quickly and the wind is from the northwest. Severe weather threat continues in Marion, Winston, Franklin, Colbert, and Limestone Counties and all points east.

Brandon Chambers April 11, 20132:39 pm

The tornado watch has been cancelled for Colbert, Franklin(AL), and Lauderdale Counties… and has been expanded to included Franklin(TN), DeKalb, and Jackson Counties until 7PM. No active warnings in effect for the Valley

Jason Manset in Moulton (@jmanset_2 on Twitter) tells us that the rain is extremely heavy but the wind is actually stronger before the thunderstorms arrive. That’s good news for now. He sent us this photo of a ragged, low cloud – it’s likely “scud” associated with the cooling effect of the rain. Use #valleywx if you’re tweeting us!

Power out.

A look at radar at 5:10PM… severe T’storm warnings continue for Jackson, DeKalb, and Marshall Counties. High winds over 60mph are the main threat. Also, watch out for street flooding.

Jason Simpson April 11, 20135:27 pm

This is what the severe storms look like on the front end before they get to you. Severe thunderstorm warnings remain in effect for Jackson, DeKalb and Marshall Counties.: (from @TerriMonroe11 on Twitter in Rainsville)

Brandon Chambers April 11, 20135:37 pm

The only severe t’storm warning in effect for the WHNT viewing area is NE Jackson and Northern DeKalb until 5:45PM for the potential for winds over 60mph

Jason Simpson April 11, 20135:53 pm

Severe thunderstorm warnings have expired, but there is still a risk of severe weather in eastern Jackson, most of DeKalb, Etowah and Cherokee Counties in North Alabama. The risk of severe storms will end by 7:00 PM in these counties. There is no more severe weather coming behind this line:

This is a view from S. Memorial Parkway in Huntsville when the severe storm was coming through South Huntsville. It looks like a tornado, but it is actually a view looking from north to south toward Walmart on Mem’l Pkwy. I believe it’s a shelf cloud. Thanks to Amanda Smith (@ayeksmith) for the Twitpic.

Jason Simpson April 11, 20136:33 pm

We’re still watching for any signs of severe weather in DeKalb, far east Jackson, Etowah, and Cherokee Counties in North Alabama. Everyone else is in the clear except for some light/moderate showers for the next 2-4 hours. This is the view from Fort Payne on Lookout Mountain from Jenna Wright (@ALshortie)

Brandon Chambers April 11, 20136:39 pm

That National Weather Service will be going out tomorrow to survey the damage that occurred today over South Huntsville to determine if the damage was caused by a tornado or straight line winds.
