DISCUSSION
Key message 1: Dry through mid-week before daily shower and thunderstorm chances return in association with a cold front starting Friday. Above normal temperatures return for the rest of the week.
It appears summer is not quite done with us yet. Another large upper anticyclone dominates the pattern through Thursday allowing for mostly dry conditions. Highs will exhibit a warming trend through Friday but more humid conditions should hold off until Thursday. Despite a cold front tracking across the forecast area on Friday, the heat and humidity will stick around through early next week as no real airmass change is expected. Temperatures will remain above normal through the period. Heat index values should remain below Heat Advisory criteria each afternoon, especially with daily chances for convection ahead of and along the cold front on Friday and as the front stalls just south of the western Carolinas this weekend. Shower and thunderstorm chances should return again Monday, mainly across the mountains.
AVIATION /12Z TUESDAY THROUGH SATURDAY/
At KCLT and elsewhere: KAVL and KHKY saw fog and stratus develop overnight with both dropping to LIFR. Fog and stratus will lift shortly after daybreak. Dry through the 06Z TAF period. East of the mountains VFR will prevail with mainly E/ENE winds. Winds at KAVL will pick up out of the SE after daybreak. Winds will go calm again at KAVL this evening into tonight. A few terminals east of the mountains should also see winds go calm this evening into tonight. Fog and low stratus may develop again at KAVL and KHKY overnight.
Outlook: Dry and VFR through Thursday outside of morning mountain valley fog and low stratus each day. A cold front should bring back daily shower and thunderstorm chances (and possible restrictions) Friday into the weekend.
