AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 253 PM CDT MON JUN 28 2010 .DISCUSSION...COLD FRONT MOVING INTO KY WITH SCATTERED THUNDERSTORMS DEVELOPING AHEAD OF IT. A LINE OF THUNDERSTORMS FROM KY INTO NORTHWEST TN APPARENTLY ALONG PREFRONTAL TROUGH. ALL OF THIS ACTIVITY WILL INCREASE AND COVERAGE AND SOMEWHAT IN INTENSITY AS THE FRONT COMES INTO THE WARM AND HUMID AIR ACROSS MID TN THIS EVENING. A FEW STRONG TO SEVERE STORMS MAY PRODUCE LOCALIZED DOWNBURST WINDS. FREQUENT LIGHTNING AND HEAVY DOWNPOURS WILL BE COMMON ACROSS THE AREA. ACTIVITY WILL DIMINISH LATE TONIGHT WITH LOSS OF HEATING. PATCHY LATE NIGHT FOG IS POSSIBLE. THE FRONT WILL SLOW DOWN AS IT REACHES OUR SOUTHERN COUNTIES...SO AT LEAST A SMALL CHANCE FOR SHOWERS/STORMS WILL CONTINUE OVER THE SOUTH HALF THROUGH TUESDAY. ONLY LIGHTLY DRIER/COOLER AIR WILL BE PUSHING IN FROM THE NORTH...SO TEMPS NEAR 90 EXPECTED. ANOTHER PUSH OF COOLER AND DRIER AIR WILL COME IN TUESDAY NIGHT INTO WEDNESDAY...BRINGING CLEARING SKIES AND MUCH MORE PLEASANT CONDITIONS FOR SEVERAL DAYS.
