Radar Analysis of Jackson County Storm
An upper-level low to our northwest has been responsible for all the rain and storms we’ve had in the Tennessee Valley over the past week. Each day, many communities experienced some form of wind damage or flash flooding, mostly tree and power line damage and brief street flooding. Many Jackson County residents in Jackson County called our newsroom and sent us pictures Tuesday of damage they say was caused by a tornado. We decided to dig through the radar data from yesterday to see what we could find.
Above is the radar image at 1:27 p.m. Thursday. At this point, there was a severe thunderstorm warning for the storm in DeKalb County, and storms were just pushing into southwestern Jackson County.
At 1:41 p.m., you begin to see some evidence of at least a core of intense wind velocity (noted by the bright ball on the right-hand side) close to Goosepond, moving toward Scottsboro.
At 1:46 p.m., the core of intense wind is still noted in the velocity as the storm is crossing HWY 35 on the north bank of the Tennessee River.
The strongest indication of a possible tornado shows up on radar at 1:51 p.m. between Scottsboro and Hollywood. Notice the tiny, but tight couplet in the wind velocity image on the right side.
At 1:56 p.m., this storm appears to have several areas of rotation (noted by the green matching up against the red), with the strongest just south of HWY 72.
The storm continued up HWY 72 through Fackler and Stevenson. The image above is yesterday’s radar at 2:00 p.m.
We received damage reports in Bridgeport as well, but based on the presentation of radar velocity, that may have been caused by straight-line wind.
Keep in mind, only the National Weather Service can rule whether or not damage was caused by a tornado and if so, how strong it was. Meteorologists with the National Weather Service in Huntsville and at the University of Alabama in Huntsville are working to determine if a tornado caused the damage in Jackson County.
Below are the reports of damage received by the NWS in Huntsville. View the interactive map of storm reports here.
