Meteorologists at the National Weather Service Office in Old Hickory are keeping their eyes on a storm system expected to move through Wilson and other counties in Middle Tennessee on Thursday which could produce damaging winds and a spin-up tornado.
The storm system was expected to move through between the hours of 5-10 a.m., but meteorologists on Wednesday pushed back the arrival time to between 10 a.m.-3 p.m., said Capt. Stephen Spencer, EMA planning officer with Wilson County Emergency Management Agency.
This means the heating of the day could influence the strength of the storms compared to a daybreak impact time, he said.
A Special Weather Statement from the NWS said a squall line was expected to move east from Arkansas and would be along the Mississippi River by 1 a.m. It was expected to weaken as it neared the Tennessee River around 8 a.m., Thursday, but showers and thunderstorms are expected to regenerate during the morning with a few possibly becoming strong to severe as they move eastward across Middle Tennessee during the day on Thursday.
The main threat will be damaging straight line winds, the statement said, adding large hail was possible, also.
The weather service does not expect a large tornado outbreak from this event, however strong winds and a spin-up tornado from a thunderstorm cell is possible, but no large tornado outbreak, Spencer noted.
The statement said that for the first three months of 2013 there have been 27 tornadoes in Tennessee with no fatalities. During the first three months of 2012, there were also 27 tornadoes and three fatalities.
