.DISCUSSION...

Moisture will gradually increase today into the weekend as a 
cold front approaches from the Great Lakes region. Coverage 
of showers and thunderstorms today will be isolated to widely 
scattered mainly in the mountains, however coverage will 
increase for Saturday as the cold front draws closer. Some 
storms could be strong to severe with damaging winds as the
main threat. Despite smoke from wildfires in Canada passing 
across the region, strong heating today will allow for minimum 
RH values this afternoon to fall into the 30s and 40s percent 
across the Piedmont, and mainly higher values over the 
mountains. Winds today will remain less than 10 mph areawide.
