.DISCUSSION...

...HEAT ADVISORY IN EFFECT FROM 11 AM TO 8 PM EDT FOR TODAY 
AND FRIDAY FOR THE LOWER ELEVATIONS...

...EXTREME HEAT WARNING IN EFFECT FROM 11 AM to 8PM EDT TODAY
AND FRIDAY FOR PARTS OF SOUTH CENTRAL VIRGINIA...

Heat risk increases to hazardous levels this week into
the holiday weekend. Additional advisories/warnings will likely 
encompass much of the region east of the Blue Ridge for the end of
the week into the holiday weekend.

An upper level ridge of high pressure will build across the
eastern U.S. this week. This feature will facilitate warming
temperatures with highs in the 80s to lower 90s in the mountains
and upper 90s to around 100 for the foothills and piedmont. 
The hot temperatures will combine with elevated dewpoints near
70 to produce peak heat indices of 95 to 100 in the mountains 
and 105 to 110 in the foothills and piedmont.

Increasing chances for showers and thunderstorms beginning 
tomorrow and into next week may cause issues with lightning- 
started fires.
