Grand Strand Forecast: Sunny Mid-Week Stretch Before Weekend Rain

Grand Strand residents, visitors, and business owners can look forward to several days of pleasant fall weather before tropical moisture brings unsettled conditions and heavy rain to the region by the weekend.

The mid-week forecast features clear skies and comfortable temperatures. On Wednesday, high temperatures are expected to reach the mid-to-upper 70s with very low humidity and plenty of sunshine. Dry conditions will carry through the rest of the work week, with Thursday and Friday seeing morning cool spots and afternoon highs reaching the upper 70s to low 80s. Cloud cover will gradually build starting Thursday afternoon and turn mostly cloudy by Friday, though conditions remain dry through Friday evening.

Weather patterns will shift over the weekend as tropical moisture associated with a developing system in the Gulf of Mexico pushes into the Carolinas. While the center of the system is forecasted to move inland along the Gulf Coast without making a direct landfall in South Carolina, its counterclockwise flow will funnel deep tropical moisture across coastal areas.

Saturday daylight hours are expected to remain manageable for outdoor plans, though cloud cover will thicken throughout the day. Rain showers are expected to increase starting Saturday afternoon and into the evening.

Sunday will bring the most significant impacts, with widespread, soaking rain and high humidity forecast across local communities. Total rainfall amounts are expected to range from 1 to 3 inches. While this moisture is beneficial for the area, it may cause minor ponding on coastal roads and disrupt outdoor activities. Meteorologists are also monitoring a low-end severe potential for isolated spin-up thunderstorms, which can occasionally occur on the eastern side of tropical systems.

Residents and commuters planning weekend travel or outdoor work should monitor local forecasts closely and prepare for wet driving conditions, particularly on Sunday.
