.DISCUSSION...


A slight cooling period will continue, with temperatures in the 
Mountains expected to be in the low to mid 80s, and Piedmont 
locations likely remaining in the 90s. This will mean heat index 
values will peak in the low 90s across the mountains, and the low
upper 90s across the Piedmont. Each day the region looks to cool 
by a few degrees, which will bring temperatures back to seasonal 
values for this time of the year. 

Increasing chances for showers and thunderstorms beginning 
today and into next week may cause issues with lightning- 
started fires; however, they will also bring much needed rainfall
to the region.
