Looks like there will be some periods of ifr and lifr weather through the early part of the forecast as a strong short wave trough makes progress from the Lower Mississippi Valley across the Southern Appalachian region. CHA will be impacted early with a nice strong southerly flow streaming in ahead of the wave. This strong low level jet will typically create downsloping scouring of lower ceilings and visibility in rain at TYS and TRI for several hours during the early part of the aviation forecast. Eventually ceilings will lower along with lowering visibility in heavier rain after sunrise into the later morning hours at these terminals. The rain wraps up from west to east through the middle part of the day at CHA and TYS but should continue into the later afternoon hours at TRI. There could be some clearing at CHA and TYS during this late portion of the forecast as drier air builds in behind the departing system.
