The storm line itself is moving east very, very slowly. It weakened considerably overnight. This morning, the line is located between Memphis and Nashville. There are no watches or warnings in effect.
The storms inside the line are moving north-north-east.
As the line itself crawls east over Davidson & Williamson Counties, storms are expected to “regenerate,” move north-north-east inside the line, and likely strengthen into strong or severe thunderstorms. Our NWS:
THUNDERSTORMS WILL STRENGTHEN AFTER 8 AM THIS MORNING WITH THE ACTIVITY LIKELY APPROACHING SEVERE LEVELS BY 10 AM OR NOON ACROSS WESTERN AREAS OF THE MID STATE. THE SEVERE THREAT WILL THEN MOVE EASTWARD THROUGH THE DAY WITH THE THREAT REACHING THE PLATEAU BETWEEN 5 PM AND 8 PM. WE ARE STILL LOOKING AT DAMAGING WINDS BEING THE PRIMARY SEVERE WEATHER THREAT. HOWEVER...LOW LEVEL SHEAR APPEARS TO BE STRONG ENOUGH SO THAT ISOLATED TORNADOES CANNOT BE RULED OUT.
The best severe wx potential for us is from noon to 3pm today:
