After a few welcome rain-free days, shower and storm chances return to the forecast for Sunday as a cold front moves into the area. We’ll start the day in the low 70s, working our way into the upper 80s in the afternoon before showers and storms kick off. Some rain could be heavy at times, and lightning may be an issue particularly inland where some stronger storms may be possible. It won’t be an all-day rainout, thankfully, but you’ll want to have your indoor plans ready to go if thunderstorms approach.

Isolated salt water flooding may also be a concern around the 7:47 PM high tide. The current total water level forecast brings the tide right to around 7′, which may be enough to cause a little flooding on the most vulnerable roads in downtown Charleston. The risk for coastal flooding around times of high tide increase throughout the first part of the week with the combination of the full moon, lunar perigee, and northeasterly winds in the wake of Sunday’s front, so stay tuned for Coastal Flood Advisories from the National Weather Service.

Warmer and a little more humid air will return to the area Friday as winds go more southerly. With high pressure remaining in control for a few more days, though, we’ll stay largely quiet weather-wise this weekend before a front starts to affect the area later Sunday.
