.DISCUSSION...

KEY MESSAGE 1: Dry conditions will persist through the weekend 

with rain chances increasing early next week. 



Deep-layered high pressure will maintain its influence across

the Southeast U.S. through the weekend yielding seasonable

temperatures and rain-free conditions. A modest sea breeze is

likely each day, but will have little impact on the convective

environment given the synoptic subsidence aloft. It will only

bring an increase in low-level moisture and a bit of gustiness 

each afternoon. Highs will warm into the upper 80s/lower 80s 

Friday and Saturday afternoons, reaching the lower-mid 90s by 

Sunday. Overnight lows will drop well into the 60s away from the

immediate coast with 70s at the beaches and Downtown 

Charleston.



Rain chances will begin to increase early next week as a broad

weakness develops aloft and low-level moisture begins to

increase. A weak cold front coupled with some sea breeze

influences could enhance the convective potential on Tuesday,

but the pattern will mostly favor typical, diurnally driven

showers/tstms from Wednesday on.

.AVIATION /00Z FRIDAY THROUGH TUESDAY/...

0Z TAFs: VFR. A sea breeze should result in SSE winds around 10

kts by early Friday afternoon. 



Extended Aviation Outlook: There are no concerns.



&&



.MARINE...

Seas have diminished enough over the Georgia offshore waters to

end the Small Craft Advisory.



Through Tonight: Sea breeze influences along the land/sea

interface and Charleston Harbor will diminish as the evening

progresses. Otherwise, southerly winds will back more northerly

overnight in response to inland cooling. Speeds will remain 10

kt or less with seas 2-4 ft.



Friday through Sunday: Marine conditions will remain on the 

quite side as high pressure prevails through the weekend. Expect

a typical summertime pattern with the modest surge of winds 

along the coastline as the afternoon sea breeze tracks inland.



Rip Currents: A moderate risk for rip currents continues through

early this evening. There is a low risk for all beaches on

Friday and Saturday.
