FLIGHT CONDITIONS WILL CONTINUE TO DETEORIATE ACROSS CHA AND TYS THIS MORNING AS THE FIRST BAND OF SHOWERS AND POSSIBLY A THUNDESTORM MOVES ACROSS THE TENNESSEE VALLEY. MAIN CONCERN THIS MORNING WILL BE LOWERING OF VISIBILITY DUE TO SHOWERS WITH CEILING REMAINING GENERALLY ABOVE 3KFT. FOR THIS AFTERNOON...GENERALLY VFR CONDITIONS AT ALL TAF SITES...EXCEPT WHERE SCATTERED SHOWERS OCCUR. THE OVERAL COVERAGE OF THE SHOWERS WILL BE LESS THIS AFTERNOON...BUT AS FRONTAL BOUNDARY APPROACHES CHA AND TYS THIS EVENING...COVERAGE AND INTENSITY OF THE SHOWERS AND THUNDERSTORMS WILL INCREASE. ALSO...FLIGHT CONDITIONS WILL DROP TO MVFR AND IFR AT CHA DURING THE EVENING. FLIGHT CONDITIONS WILL DROP TO IFR AT TYS AND CHA AFTER 06Z. TIGHT PRESSURE GRADIENTS AHEAD OF INCOMING FRONTAL BOUNDARY WILL PRODUCE BREEZY SOUTHWEST WINDS THROUGH THE PERIOD...ESPECIALLY DURING THE AFTERNOON TODAY AND IN/NEAR STORMS. COLD FRONT WILL MOVE ACROSS THE TAF SITES OVERNIGHT (CHA 04Z...TYS 06Z AND TRI 08Z). WINDS WILL BECOME NORTHWEST 12-17KTS WITH GUSTS UP TO 25KTS AT CHA AND TYS.
