.DISCUSSION...Will see little change in the weather pattern 
with high pressure remaining in control.  A few isolated 
thunderstorms will develop over higher elevations today. It is 
possible a stray storm could drift into the TN Valley but this 
coverage should be quite limited. Any storm that does develop will 
be capable of brief heavy rainfall.  The main concern continues to 
be the heat. High temperatures this afternoon will again reach into 
the upper 80s and 90s and with dewpoints in the 70s...expect to see 
heat indices reach into the mid to upper 90s. A few 
showers/thunderstorms are developing this morning...earlier than 
expected.  As a result...will update the current forecast 
package for the increased chance of morning convection.
