The NWS posted a video of the radar on social media Friday afternoon, with the following description:
“Our survey team confirmed an EF-2 tornado in Scott County, TN. Here is radar as the tornadic cell tracked through between 5:50 & 6:30PM yesterday evening. A reflectivity hook developed as it approached Norma (top left) with a rotational velocity couplet tightening (red/green close together at top right) & correlation coefficient showing debris in the air (dark blue/green mass near Norma bottom left). At the same time, normalized rotation also strengthened near Norma indicated by the bright green dot at bottom right. This strong rotation with debris seen in the air continued as the storm tracked south of Pioneer indicating a tornado on the ground. The rotation and hook echo became less defined as the storm continued east of Pioneer with an overall weakening trend.”
The length and width of the storm has not yet been released by the NWS. However, an EF-2 tornado — which is the third step on the NWS’s six-step Enhanced Fujita scale and is considered a strong tornado — packs maximum winds of 111 mph to 135 mph.
