Beware of black ice Tuesday evening as ‘a rapid freeze up’ sets in after day of rain – Charlotte Observer

This story was updated at 6 a.m. Tuesday.

Chances of snow have diminished Tuesday afternoon in the Charlotte region, but the possibility of black ice remains as forecasters predict a drastic drop in temperatures after a day of rain.

There is a 90 percent chance of precipitation Tuesday afternoon and a 50 percent chance Tuesday night, when temperatures will fall to 22 degrees, says the National Weather Service.

If snow falls near Charlotte, it would “brief and light,” starting after 4 p.m., forecasters say.

“A strong cold front will cross the area,” say NWS forecasters. “Very cold air will move in behind the front. Average temperatures may be nearly 15 degrees below normal Wednesday and Thursday which could cause significant impacts.”

Chances of accumulation are unlikely in the Charlotte region, say forecasters.

AccuWeather is calling for “a rapid freeze up” as temperatures dip below freezing at 6 p.m. and fall to 26 degrees by midnight.

WBTV meteorologist Al Conklin says the region will not likely get much snow.

“However, black ice will still be a possibility with temps crashing to around 20° for lows Tuesday night after the rain ends,” according to Conklin’s report on WBTV.com.

“A winter weather advisory has been issued Tuesday for the mountains and northern foothills, where the cold air and moisture will likely have better luck over-lapping.”

On Monday morning, the National Weather Service upgraded that advisory to a Winter Storm Warning for higher elevations in southwest North Carolina.

“There remains a flash freeze potential across the mountains this afternoon, so we will wait to see how that evolves,” says the National Weather Service.

Snow will begin falling in that region after midnight, with dangerous wind chills and “isolated to scattered downed trees and power lines,” says the National Weather Service.

Up to five inches could fall in western counties and wind chills could be a low as negative 10 degrees in Newland and negative 3 degrees in Burnsville, says the NWS.

The wind chill in the Charlotte region could be around 17 degrees as the front passes through, says the National Weather Service.

“Bitter cold” will follow later this week, with highs in the 30s Wednesday and Thursday and lows in the 20s, according to WBTV.
