It may not be a snow storm, but even a light glaze of ice has the potential to cause isolated power outages and treacherous roadways. The good news is that temperatures will be rising throughout the day Saturday and conditions should improve around mid-morning.

The advisory calls for a trace of snow and sleet along with a tenth of an inch of ice. Precipitation will start around midnight as snow or sleet. Up to a half-inch of\u00a0snow is possible\u00a0in the College Park area, but lesser amounts are likely. Northern regions of Maryland can expect as much as 1 inch. Snow and sleet will transition to freezing rain around 4 am and leave a thin glaze of ice by morning. Winds will be out of the south at 5 to 10 mph.<\/p>\n<div id=\"attachment_1563\" style=\"width: 1076px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-1563\" class=\"wp-image-1563 size-full\" src=\"http:\/\/weather.umd.edu\/wordpress\/wp-content\/uploads\/2016\/12\/StormTotalSnowWeb.jpg\" alt=\"NWS snow forecast shows less than 1 inch is likely across the region\" width=\"1066\" height=\"788\" srcset=\"https:\/\/weather.umd.edu\/wordpress\/wp-content\/uploads\/2016\/12\/StormTotalSnowWeb.jpg 1066w, https:\/\/weather.umd.edu\/wordpress\/wp-content\/uploads\/2016\/12\/StormTotalSnowWeb-500x370.jpg 500w, https:\/\/weather.umd.edu\/wordpress\/wp-content\/uploads\/2016\/12\/StormTotalSnowWeb-800x591.jpg 800w\" sizes=\"auto, (max-width: 1066px) 100vw, 1066px\" \/><p id=\"caption-attachment-1563\" class=\"wp-caption-text\"><em>NWS snow forecast shows less than 1 inch is likely across the region.
