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 /18Z THURSDAY THROUGH MONDAY/

04/18z TAF Discussion: KCHS/KJZI/KSAV: VFR through 05/18z. Some gustiness will accompany the sea breeze this 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.
