CHARLESTON, SC (WCSC) - Unseasonably hot and humid weather will cover the Lowcountry for the next few days, pushing the heat index into three digits over the weekend.
The heat index is expected to approach 100 degrees on Friday, according to Live 5 Meteorologist Brad Miller. But the heat index on Saturday and Sunday could surpass the century mark.
The National Weather Service will issue a heat advisory if the heat index is expected to reach 105 degrees for at least four hours on either Saturday or Sunday.
Despite the heat, temperatures should still be below record highs, Miller said. Friday's record high is 96, set in 2010; while Saturday's record is 99, set in 2011. Sunday's all-time high of 99 was set one year earlier in 2010.
The first day of summer is Sunday, June 21.
