AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NASHVILLE TN
1043 AM CDT THU AUG 21 2014

.UPDATE...FOR MORNING DISCUSSION.

&&

.DISCUSSION.

WITH THE INFLUENCE OF THE UPPER LEVEL RIDGE SITUATED JUST OFF TO
OUR WEST...RAIN CHANCES WILL BE CONSIDERABLY LOWER THAN YESTERDAY.
SHOWERS AND THUNDERSTORMS OFF TO OUR NORTH WILL CONTINUE TO
TRAVERSE THE TOP OF THE RIDGE AND IF WE END UP WITH ANY CONVECTION
IN MIDDLE TENNESSEE TODAY...IT WILL LIKELY BE CAUSED BY OUTFLOW
BOUNDARIES PROPAGATING INTO THE AREA VERSUS HOMEGROWN THUNDERSTORMS.
WILL CONTINUE WITH JUST A SLIGHT CHANCE TO CHANCE POP EAST OF
INTERSTATE 65...WITH THE BEST CHANCES FOR CONVECTION AND ONE OF
THESE OUTFLOWS BREAKING INTO THE MID-STATE OVER THE NORTHERN
PLATEAU REGION LATER THIS AFTERNOON.

OTHERWISE...TEMPERATURES WILL SOAR INTO THE MIDDLE 90S THIS
AFTERNOON. DEW POINTS ARE EXPECTED TO DIP INTO THE MIDDLE 60S
/CURRENTLY IN THE LOW 70S/ AS MID-LEVEL DRY AIR EVIDENT IN THE
LATEST WATER VAPOR IMAGERY GETS MIXED DOWN TO THE SURFACE. THIS
SHOULD ALLOW FOR HEAT INDEX VALUES IN THE 99-101 RANGE ACROSS OUR
FAR WESTERN COUNTIES...KEEPING US BELOW HEAT ADVISORY CRITERIA.

UPDATES OUT.
