MONDAY OUTLOOK

• Temperatures will not rise above freezing until Monday afternoon.
• With low temperatures, the rain freezes on contact with the ground, creating icy conditions. Black ice is a big threat.
• Full sunshine returns Monday, so we will warm up to near 40 degrees by the afternoon.
• Any ice that doesn’t melt will refreeze Monday night into Tuesday morning, as temps fall to below freezing overnight.
• Be prepared for several days of impact!
• Expect more sun Tuesday, and more melting with highs in the mid 40s.
• Rain chance to move in late Wednesday, but it looks like just the mountains could see some snow.
• We will watch another system on Friday that could bring another wintry mix areawide though.

Winter storm brought snow, sleet, ice to the Carolinas Sunday

A winter storm combining high winds and ice swept through parts of the U.S. Southeast on Sunday, knocking out power, felling trees and fences and coating roads with a treacherous, frigid glaze.

More than 1,800 NCDOT employees in 1,200 trucks applied nearly 10,000 tons of salt while plowing essential routes by 3 p.m. Sunday.

Tens of thousands of customers were without power in North Carolina and South Carolina Sunday evening, including 10,000 Duke Energy customers in the Charlotte area.

Highway patrols reported hundreds of vehicle crashes across the Carolinas, and Charlotte-Mecklenburg police said it responded to 53 wrecks Sunday.

The winter storm also impacted airlines, with more than 1,200 Sunday flights at Charlotte Douglas International canceled – more than 90% of the airport’s Sunday schedule, according to the flight tracking service flightaware.com.

Flight cancellations continued into Monday, with American Airlines, which operates 90% of CLT flights, canceling more than 100 flights for Monday.

Ahead of the storm, North Carolina Gov. Roy Cooper and South Carolina Gov. Henry McMaster issued state of emergencies as workers in both states spent days getting state roads ready for the storm -- particularly preparing for ice.
