...HAZARDOUS TRAVEL CONDITIONS TO PERSIST THROUGH THE EARLY
MORNING HOURS...

While additional frozen precipitation is not forecast through the
early morning, many road surfaces, especially secondary and rural
roads, remain sleet and ice covered, slick and dangerous. Use
caution when driving or walking on icy surfaces. Additionally,
even in locales where roads have been cleared and treated, lows in
the mid teens to near 20 could cause those surfaces to refreeze
as well, potentially as black ice.
