2.2 SSW Trinity Representatives from the National Weather Service and Morgan County Emergency Management completed a survey of damage in the city of Trinity, AL. The survey found evidence of an EF-0 tornado on the Enhanced Fujita S cale, with highest winds of 65 mph. The damage was confined mostly to uprooted trees and snapped limbs. One residence sustained some damage, mainly to sheds and fencing at the back of the property. An upper level circulation or disturbance known in meteorology as a Mesoscale-Convective-Vorticity center tracked eastward through the central Tennessee Valley during the morning hours. A moist an unstable airmass enabled rapid low-topped shower development by late morning as this system tracked through the area. A brief weak tornado was sighted in Trinity. This was in close proximity to the upper level circulation mentioned above. As this shower entered Madison, AL further to the east, a NWS employee observed thunder being heard, likely from a cloud to cloud lightning flash. Otherwise, no other cloud to ground lightning was noted, making this tornado an interesting phenomenon for further study. The University of Alabama-Huntsville ARMOR dual-polarization radar located at the Huntsville International Airport was in close proximity to this tornado and identified a couple of small low-level circulations within a band these showers, one in the vicinity of the tornado. Start: 34.5900/-87.0900 End: 34.5900/-87.0900
