Sunday will bring another hot and humid day, and usher in the beginning of a wetter pattern across the area.

Saturday brought temperatures in the 90s again, with humidity making some areas feel like 100°. However, more cloud cover offered slight relief from the intense heat.

Sunday will have another mild and muggy start, with temperatures in the low to mid 70s under partly to mostly cloudy skies.

Sunday will mostly mirror the recent weather, other than an increase in cloudiness. Temperatures will climb into the 90s, with humidity slightly raising the heat index.

A cold front approaching the region will decelerate as it reaches the Coastal Empire and Lowcountry, likely triggering isolated showers and storms on Sunday afternoon due to its timing.

A few pockets of heavy rain may create localized flooding in areas that drain poorly. Rain chances will diminish after sunset.

A Look Ahead

The stalling front offshore will focus moisture and increase rain chances from Monday to Wednesday. Each day will start with mild temperatures and bring scattered showers, and possible thunder, both around daybreak and later in the afternoon.

Next week, temperatures will dip to below-average levels. Mornings will gradually cool to the 60s, while afternoons will peak only in the low to mid-80s.

As the week progresses, rain chances will decrease to 20-30%, allowing for more sunshine. By the week’s end, afternoons will warm slightly, with temperatures reaching the upper 80s.

Tropics

The tropics continue to bring better news as a tropical wave, designated as Invest-91L, now only has a 20% chance of developing into a depression or named storm. Dry, stable air continues to limit thunderstorm development and organization.

The disturbance will move westward into the Caribbean Sea but does not appear to have any significant development based on computer model data.

There are no tropical threats to the Coastal Empire and Lowcountry at this time.
