Marine Weather and Tide Forecast for Myrtle Beach, SC

NEAR TERM /THROUGH FRIDAY/
A cold front will pass through the area this evening, accompanied by sct-bkn clouds but little or no rain. Cooler and drier air will filter in behind it resulting in slightly below normal temperatures tonight and Friday. Lows tonight will fall to the upper 50s to lower 60s. Highs Friday will be in the upper 70s to lower 80s.

SHORT TERM /FRIDAY NIGHT THROUGH SATURDAY NIGHT/
High pressure will dominate through much of the weekend. Dry air and cooler temperatures will hover at or slightly below normal for late May. Expect afternoon highs around 80 with overnight lows in the lower 60s. Saturday morning could start in the mid and upper 50s.

LONG TERM /SUNDAY THROUGH THURSDAY/
Flattening mid level flow over the southeastern US and a frontal boundary to our south will reintroduce rain chances on Sunday (especially over southern parts of the area). The front lifts toward the area on Monday with a coastal trough developing offshore as a broad area of low pressure also builds across the southern Plains and southeastern US. A series of weak shortwaves will follow the front through early next week. The best chance of showers and thunderstorms looks to be Tuesday as a wave of low pressure moves across a stalled frontal boundary which will reside across the area.

AVIATION /18Z THURSDAY THROUGH TUESDAY/
High confidence in VFR conditions through 18Z Friday. Main issue this afternoon will be gusty W-SW winds which will shift to the W- NW after a cold front moves through this evening.

Extended Outlook... High confidence in VFR through early Sun.
An increasing risk for flight restrictions starting late Sun through Tue as a frontal system affects the area.

Friday Night through Tuesday... High pressure settles overhead this weekend, expect light and generally offshore winds. Nearly perfect boating conditions with seas around 1-2 feet. On Sunday, high pressure moves offshore and southerly winds develop as a weak frontal boundary approaches from the south. Onshore flow increases on Monday as a coastal trough develops and the weak front inches closer. Unsettled weather is expected to develop along this trough early next week.
