DISCUSSION...Latest analysis shows a surface outflow boundary which has settled southward in a west-to-east manner, and is now residing just south of the Nashville metro area. Repeated bands of showers and embedded thunderstorms have moved across this region this morning and afternoon, within an environment of minimal CAPE (as sampled by the BNA 18Z RAOB) but strong deep-layer speed shear. Within the past hour, a stronger convective cell briefly acquired low-level rotation -- as it interacted with the aforementioned outflow boundary, but quickly weakened thereafter. Similar behavior with one or two other cells may occur over the next couple of hours, where the main severe risk would be a brief tornado, or a locally strong/severe wind gust. Overall severe risk should remain low however, within the broad low-level warm advection regime beneath weakly anticyclonic mid-level flow. As such, WW is not anticipated at this time. ..Goss/Guyer.. 02/06/2019 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...MRX...OHX...HUN...MEG...
