West Tennessee is leading the heat parade, hitting 80 degrees this afternoon. Middle Tennessee climbs to 78. Over in East Tennessee, you're looking at 75 degrees — still perfect weather for a cookout. But hold on. Changes are brewing out west. Thunderstorms develop between 6 P.M. and 10 P.M. Around Memphis. Lows dip to 65 degrees there. Middle Tennessee stays mostly cloudy with a low of 64. East Tennessee drops to 53 under partly cloudy skies — the cool spot tonight. Thursday keeps the summer vibe going.  ...
