The coldest air-mass in years has settled into the Coastal Empire and Lowcountry on Monday morning.
A weak disturbance riding along a trough of low pressure has interacted with cold air to produce areas of freezing drizzle and perhaps a few sleet pellets across areas mainly north of the Altamaha River.
Remaining moisture may freeze on elevated surfaces, including bridges and overpasses, enough to produce slippery road conditions. A very thin glaze of ice may also accumulate on trees and power lines. However, amounts will not be great enough to cause any tree damage or power outages.
While the risk is still low, please use extra caution if you must travel before 10 a.m., especially if driving on a bridge, overpass or elevated portion of a roadway.
The sky clears out as drier air moves in later this morning, allowing temperatures to warm above freezing and any risk of ice to decrease.
While ice is not a risk tonight, cold temperatures and frigid wind chills are likely to develop across the much of the southeast.
Wind chill values may dip into the single-digits before 9 a.m. Tuesday.

Our next, presently low risk of wintry precipitation arrives Wednesday as an area of low pressure passes offshore; possibly sending moisture into our coastline with cold air already in place. If this were to happen, sleet and snow would occur primarily across the southeastern half of the WTOC Viewing Area.
However, the exact track of the low is uncertainty and even a 50-mile shift in the movement would have huge impacts on our local forecast.
We’ll keep you updated on TV, at WTOC.com, and in the WTOC Weather App.
