Severe threat

. Anywhere in Western KY and Middle TN needs to watch out for tonight and early tomorrow morning. An extensive squall line/perhapes even serial derecho is expected tonight. Bow echos and supercells will be present along this line. Development out ahead of the line cannot be ruled out. Anyone in a mobile homes needs to stay the night somewhere else as these homes can be tossed around in 80+MPH winds. The wind damage will likely be widespread across the area tonight as 60-80MPH(locally up to 100MPH winds may occur) due to the intense shear. Tornadoes are a threat as well. The EF-2 Tornado that hit the industrial park in Hopkinsville on 4/4/2011 and the Parsons TN EF-2 that hit on 2/24/2011 are examples of tornadoes that can form in squall lines. This shows that we cannot rule out a tornadoes in events like this. Keep NOAA Radios and any other sources charged up and battery powered and ready to go. I will post an updated map by 4pm.
