WHAT HAS CHANGED

The Aviation Section has been updated for the 13/12z TAFs.

KEY MESSAGES

- 1) Dry weather and above-normal temperatures through next weekend.

DISCUSSION

KEY MESSAGE 1: Dry weather and above-normal temperatures through next weekend.

Prominent ridging aloft and subtropical high pressure at the surface will yield a rain-free forecast with well-above average temperatures across the region for the next 7 days. Temperatures will range into the low to mid 80s through Monday, then mid 80s to low 90s on Tuesday through the weekend. These values would be on the order of 10 degrees (or more) above normal. High temperatures could approach the daily records as early as Tuesday and continuing into the weekend (see Climate section). Also, certainly not the most ideal setup with the ongoing Extreme Drought (D3) impacting much of the area on the U.S. Drought Monitor.

AVIATION /12Z MONDAY THROUGH FRIDAY/

13/12z TAF Discussion: KCHS/KJZI/KSAV: Shallow ground fog will quickly mix out just after daybreak. VFR will prevail. Another round of shallow ground fog could impact the terminals again early Tuesday morning, but no meaningful impacts are expected.

Extended Aviation Outlook: VFR.

MARINE

There are no meaningful concerns this week. Stubborn subtropical high pressure centered well offshore will maintain a broad southerly flow regime across the waters through Friday. Typical sea breeze surges are likely each afternoon, mainly along the land/sea interface and Charleston Harbor.

Rip Currents: The combination of a slightly stronger sea breeze circulation this afternoon coupled with a 3 ft, 10 second easterly swell will support a moderate risk for rip currents along the Georgia beaches today. Swell heights will run tad lower along the lower South Carolina coast (2 ft), so a low risk was maintained there. A low risk was highlighted for all beaches for Tuesday; however, the risk will be near moderate thresholds for the Georgia beaches similar to today. So an upgrade to a moderate risk may be needed later.
