Another chilly start to our day with temperatures flirting with the freezing mark at sunrise this morning. Cold high pressure over Canada is extending south into the Mid-Atlantic region this weekend. This cold air will eventually clash with our approaching storm system incoming out of the southwest. The threat of snow, sleet and freezing rain will linger tonight through early Sunday.
Winter Storm Warnings and Advisories will go into effect for much of central and western North Carolina at 6 PM Saturday and last until 6 PM Sunday.
Other than the cold, our weather through much of our Saturday will be a non-issue. Cloudy skies as temperatures gradually warm from cold to not as cold. Highs today will be below average ranging from the low to mid 40s. A few snowflakes may make their way to the ground throughout the day. But most of the precipitation that will fall during the day will evaporate before reaching the ground due to dry air still dominate in the area.
Moisture will increase this evening and tonight as our storm system marches northeast into the region. Most will experience a cold rain tonight and overnight. But for area north and west of I-85 the potential for freezing rain, sleet and snow will be present after 8 PM.
For areas north and west of Raleigh, a tenth of an inch of ice accumulation is possible. That amount increases the farther north and west you go. For portions of the Greensboro-Triad area, some locations may receive two tenths to a third of an inch of ice. Remember thats total accumulation between Saturday and Sunday evening.
Power outages will be possible due to snow and ice accumulation, and be cautious on the roads Sunday morning. Bridges and overpasses are the most susceptible to ice accumulation.
Thankfully this is not looking like a repeat of our snow event back in December last year. Many will primarily deal with a cold rain tonight and through much of Sunday morning. Precipitation will taper off through Sunday afternoon.
High pressure will build into the region Monday as our storm system exits the area and move offshore. Monday will be a dry but still cloudy and bitterly cold day. Temperatures will begin to rebound Tuesday with the return of bright and sunny weather.
