A Winter Weather Advisory has been announced for much of the eastern part of the U.S. starting at 1 a.m. Monday morning and continuing through 10 a.m. Tuesday, according to the National Weather Service.
“NWS expects three to five inches of snow and sleet to fall, and a tenth of an inch of ice from freezing rain.”
According to Insta-Weather PLUS meteorologist Tony Pann, snow will begin falling during the day Monday, followed by warmer air from the south in the late afternoon and evening that is expected to bring with it a round of sleet and freezing rain. WBAL reports that the NWS Winter Weather Advisory expects accumulation to reach between two and four inches of snow and sleet, with precipitation turning to rain by late Monday night or early Tuesday morning. Temperatures are expected to remain in the teens Sunday night and Monday morning before rising into the upper 30s by Monday night.
“Snow and ice will cause slippery roads and travel will be difficult. A Winter Weather Advisory means that periods of snow, sleet or freezing rain will cause travel difficulties. Be prepared for slippery roads and limited visibilities. Use caution while driving.”
The current Winter Weather Advisory also includes a Winter Storm Warning for areas further west, including for Frederick and Washington counties in Maryland, and parts of Loudoun County in Virginia, reported CBS D.C. In these areas, the NWS expects between four and eight inches of snow and sleet, followed by at least a quarter inch of ice from freezing rain.
The storm’s effects will be felt as far west as Ohio, Indiana, and Illinois, and as far south as Georgia, with the NWS issuing a Winter Weather Advisory for the entire region and The Weather Channel making the decision to name the front Winter Storm Olympia. This important designation signals that officials expect the storm to affect more than two million people.
The Weather Channel also reported that winter storm watches have been issued by the NWS from parts of northern Georgia all the way through the Appalachian states and into the mid-Atlantic region.
“An expansive winter storm will spread snow, ice and even rain in some northern locations of the East, South and Midwest through the Presidents’ Day holiday and Tuesday.”
The Winter Weather Advisory comes as a blast of Arctic air is ushered in by a strong high pressure system, bringing the coldest temps seen so far this winter to the northeast over the weekend. A low pressure system tracking up the east coast is bringing cold winter weather to the entire region, with light to moderate snow falling from the upper Midwest into the lower Ohio River Valley, with sleet and freezing rain possible in southern Missouri, northern Arkansas, western Kentucky and west Tennessee.
Snow is also expected to fall in other parts of the Ohio Valley, as well as the Appalachians and Piedmont of the Carolinas Sunday night. Some freezing rain is also possible on the southern end of the band of precipitation Sunday.
“Slick roads (particularly bridges/overpasses) are possible due to sleet/ice accumulations in Missouri/Arkansas. Ice accumulations look light enough to avoid widespread power outages and tree damage impacts.”
The current Winter Weather Advisory follows a round of record snowfall along parts of the east coast earlier this winter.
