4/15/2011: Storm Chase Log Part I

Friday, April 15, 2011 proved to be one the most intense chases we’ve ever been on, and was certainly the most intense chase we’ve had in the state of Alabama. For nine straight hours the western portion of the state was battered by supercells and tornadoes. This is a recap of that day from our perspective.

We departed our office around 8:00AM and met with our rider, Justin Chandler, for the day in Birmingham. We then traveled to Tuscaloosa and initially were going after some storms that had fired to the north of there. While we were sitting in traffic on the bypass, a supercell erupted just across the Alabama/Mississippi border in Wayne County, MS and immediately began rotating. This storm went tornado warned within the first 20 minutes of its life. We spun around and headed south down I20/59 then AL28 toward Livingston, AL. We intercepted the storm just south of Linden in Central Marengo County, AL. Timing and placement were perfect. Just as we approached an open intersection at AL69 and AL10 a massive multi-vortex tornado appeared from our right. Below is a video clip from that. We would later learn that this tornado killed a person in a mobile home just southeast of Linden. Due to our partnership with WBRC-TV FOX-6 in Birmingham, Brett was in contact with Robert (Our Producer) for the afternoon.  Here is a view LIVE of what Mickey Furgueson and the rest of the FOX-6 Storm Warn team were viewing from our vehicle during the noon newscast.

This really set the tone for the rest of the day and the outbreak.  The storms was really wrapping up as we sat at the intersection of AL-10/AL-69.  Here is our view of the radar as the cell approached and came right over our location.

This was radar imagery of the tornadic circulation as they approached us and crossed our area.  Figures 3 and 4 show the significant inbound and outbound winds showing strong rotation and the tornado as it approached and passed us.  This was our first storm intercept of the day….and there were several more.  I will be making an updated post of the next few videos that I take off when I get a chance. 

I will leave you with this radar and Water Vapor image of the entire outbreak.
