UPDATE 6:18 PM: The tornado watch has been canceled.
The Storm Prediction Center has issued a tornado watch for the Lowcountry, including the entire Charleston Tri-County area, until 9PM. We in #chswx continue to watch an area of low pressure strengthen as it heads eastward. While instability is lacking, wind shear is plentiful, and the approaching low pressure will only assist in ramping this up. Thus, the watch.
