.DISCUSSION...
KEY MESSAGE 1: Dry weather and above-normal temperatures will
continue through the weekend.

Prominent ridging aloft and subtropical high pressure at the surface
will continue to support dry weather and above-normal temperatures
through the weekend. Temperatures will range into the upper 80s to
low 90s this afternoon and through the weekend. These values would
be on the order of 10 degrees (or more) above normal. High
temperatures could approach the daily records today, with the
best chances of reaching records on Friday and Saturday (see
Climate section below). The beaches will feel considerably
cooler (possibly 10 to 15 degrees cooler) with onshore flow and
water temperatures remaining in the mid-60s. The combination of
well above normal temperatures and no rainfall will only serve
to further worsen ongoing Extreme (D3) drought conditions
highlighted by the U.S. Drought Monitor.

.AVIATION /06Z WEDNESDAY THROUGH SUNDAY/...
15/06z TAF Discussion:
KCHS/KJZI/KSAV: VFR for much of the 06z TAF period. Some shallow
ground fog could develop just before daybreak similar to the
past several mornings. No meaningful impacts are expected,
although a brief period of MVFR vsbys could occur.

Extended Aviation Outlook: VFR.

&&

.MARINE...
Atlantic high pressure centered well offshore will maintain a
southerly flow regime into Saturday. This pattern favors robust sea
breeze surges each afternoon with the highest winds remaining
confined to areas near the land/sea interface as well as the
Charleston Harbor during the mid-afternoon to early evening hours.
Gusts in these areas could reach as high as 20 kt at times.

A strong cold front is expected to push across the coastal waters
Sunday which will bring a dramatic increase in both winds and seas,
likely reaching as high as 25-30 kt with gusts near gale force.
Small Craft Advisories will most certainly be needed with Gale
Watches/Warnings possible, especially over the 20-60 NM offshore
zones.

Rip Currents: A moderate risk of rip currents is in place for all
beaches through Thursday. The combination of 2-3 ft swell with a
period of ~10 seconds, moderate onshore winds and an increasing
astronomical influence from an approaching full moon will be enough
to support a higher rip current risk. An elevated risk for rip
currents will likely persist into the weekend and especially into
early next week as a pinched gradient, northeast wind event develops
behind a strong cold front.
