The heaviest of the rain is over for the Grand Strand, but cold temperatures could mean issues with black ice on roadways early Friday, according to the National Weather Service in Wilmington, N.C.
“Rain is quickly exiting the coast at this time, but periods of light rain and drizzle will persist through late morning,” said Joshua Weiss with the weather service Thursday. “At the same time, colder air behind the departing low pressure system will begin to filter southward toward the area.”
In a special weather statement issued at 2:17 p.m. Thursday, forecasters said patchy ice is expected to develop overnight as temperatures dive to near 30 degrees.
“Freezing fog is expected to develop late [Thursday] as temperatures drop below freezing and then continue into early Friday morning,” forecasters wrote in the statement. “This fog will coat exposed surfaces with a very fine layer of ice.”
Visibility is expected to be reduced to two miles or less in most places, but some areas residents could see dense fog with visibility restricted to a quarter mile.
“Late [Thursday], temperatures will drop to well below freezing across most of the area,” Weiss said. “This may produce some black ice issues due to re-freezing, especially along elevated and secondary roadways.”
Motorists, especially those who drive secondary roads, are warned to use caution late Thursday and Friday morning, particularly around bridges and overpasses, officials said. Some walkways and other wet places also could freeze overnight, as well.
Daytime highs on Friday will be about 48 with partly sunny skies, but overnight lows will dip to near 29 degrees with windy gusts up to 21 mph, according to the forecast. On Saturday, partly sunny skies return with a high near 43 and overnight low of 32 degrees, but the windy conditions remain with gusts expected near 23 mph.
