Area Forecast Discussion National Weather Service Morristown TN 733 AM EDT Mon Apr 8 2019 .AVIATION... The 12z TAF period will be a difficult one, with multiple rounds of showers and thunderstorms affecting most terminals, especially KCHA which will be closer to the upper low that is responsible for convection. Timing in significant breaks will be difficult, but have tried to show a break beginning late this morning before next wave of convection arrives in earnest late this afternoon and evening. KCHA is likely to see several hours of VCSH/VCTS this afternoon through tonight as upper low draws near. && .MRX WATCHES/WARNINGS/ADVISORIES... NC...None. TN...None. VA...None. && CD
