There is increasing chance for icy roads and a wintry mix falling on South Mississippi, the National Weather Service advised Tuesday evening.

Temperatures are expected to drop the lowest they’ve been all season, and wind chill values are likely to be into the single-digits across the Coast.

Radar showed a band of moisture moving southeast toward the area at about 5 p.m. has held up pretty well and not dissipated much in the windy conditions.

The precipitation is still expected to be “very light” but the frigid temperatures mean any wetness on the roads could freeze into black ice and stay that way until temperatures rise above freezing after noon Wednesday.

The Harrison County Emergency Management Agency warns accumulation of a trace to just over an inch is possible.

“Whatever falls and accumulates now will not melt,” the agency warns. “This will lead to icy spots on elevated roadways, bridges, and overpasses tonight and well into tomorrow. This threat is possible across the north and south shores along with coastal Mississippi if we see any accumulating precipitation tonight.”

As of Tuesday evening, precipitation is possible across the Coast from midnight through 4 a.m.

A winter weather advisory is in effect until midnight Tuesday, meaning winter precipitation will make travel dangerous. A wind chill advisory is in effect until 11 a.m. Wednesday. A hard freeze warning is in effect until noon Wednesday.

Wednesday’s high is only expected to warm to the 30s, and wind chill could make it feel like the 20s. Clear skies and low humidity will allow Wednesday night’s temperature to again dip into the 20s.

Several Coast schools have canceled Wednesday classes.
