.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 /18Z FRIDAY THROUGH WEDNESDAY/...

At KCLT and elsewhere: VFR conditions will prevail through the

forecast period with patches of thin cirrus expected. There will

be another round of mountain valley fog/low stratus by daybreak

Saturday, but expected to remain away from KAVL. Light southwest

winds through this afternoon and becoming light and variable

overnight. Winds pick up out of the southwest again by Saturday

afternoon at 5-10 kts.



Outlook: Expect dry, VFR conditions to continue into the weekend.

The potential for morning mtn valley fog/low stratus will gradually

increase each day. Diurnal convection returns next week.
