IN THE WAKE OF A COLD FRONT THAT DROPPED THROUGH THE REGION EARLY THIS MORNING...MUCH COOLER/DRIER AIR HAS FILTERED INTO THE SOUTHERN APPALACHIANS AND TENNESSEE VALLEY. WITH A DOME OF HIGH PRESSURE BUILDING IN...A CLEAR SKY HAS PROMOTED GOOD RADIATIONAL COOLING THIS EVENING...AS TEMPS HAVE FALLEN WELL INTO THE MID 50S TO LOWER 60S AS OF 9 PM EDT. WITH DEWPOINTS IN THE MID TO UPPER 40S...LOWS SHOULD HAVE NO PROBLEM BOTTOMING OUT IN THE MID 40S TO LOWER 50S ACROSS MOST OF THE VALLEY LOCATIONS BY EARLY TUESDAY MORNING. IN ADDITION...THE CLEAR CONDITIONS ALONG WITH THE COOLER AIR TEMPS AND WARM WATER TEMPS WILL ALLOW FOR A GOOD SETUP FOR FOG DEVELOPMENT ALONG AREA LAKES/RIVERS TONIGHT. THUS...HAVE ADDED THIS TO THE ZONES...THOUGH THINK NORTHERLY WINDS WILL BE JUST PERSISTENT ENOUGH FROM MAKING THIS FOG DEVELOPMENT TOO WIDESPREAD.
