DISCUSSION

Key message 1: Dry conditions with a warming trend through Saturday. Shower and thunderstorm chances return early next week.

Deep layer ridging over the southeastern CONUS remains in place through Saturday. Mostly clear skies with periods of cirrus are expected. Max temperatures are expected to be near normal this afternoon and nudging up a few ticks on Saturday with widespread mid to upper 80s outside the mountains and major mountain valleys, with even a few spots flirting with the 90 degree mark along and east of I-77. Dewpoints are on the rise, but still at values to make conditions outside feel fairly comfortable for early June.

Vigorous shortwave will move towards the eastern CONUS and allow for the ridge to gradually breakdown, while a surface high shifts offshore the Mid-Atlantic Coast during the early part of next week. A backdoor front shown moving towards the area and could allow for weak CAD to develop late Monday into Tuesday. With the damming high in place with more clouds and higher PoPs, expect temperatures to return back to normal values or even slightly below. A warming trend returns later next week after Tuesday with 90s possible by the end of the forecast period. Chances of mainly diurnal convection increases next week as well with better moisture influx from the Gulf and a relatively active synoptic setup.

AVIATION /00Z SATURDAY THROUGH WEDNESDAY/

At KCLT and elsewhere: Expect dry, VFR conditions to continue thru the 00z TAF period. SCT to BKN cirrus this evening will diminish later tonight with more SCT cirrus expected again tomorrow afternoon/evening. Another round of patchy mountain valley fog/low stratus is likely around daybreak Sat, but it is not expected to reach KAVL. SWLY winds will weaken tonight/ overnight with some sites likely going calm. Winds pick back up from the SW again tomorrow afternoon with speeds between 5 and 10 kts.

Outlook: Expect dry, VFR conditions to continue into the weekend. The potential for morning mountain valley fog/low stratus will gradually increase each day. Diurnal convection returns early next week.
