A mixture of freezing rain, sleet, and snow have been seen across the St. Louis region on Sunday. FOX 2 extreme weather specialist Chris Higgins explains the difference between freezing rain and sleet and the danger they bring to roadways.

Winter storm warnings will take effect at noon on Sunday. On Sunday, the morning will stay dry, but snow will move in by the afternoon. Highs will reach the upper 20s to low 30s. Snow will mix with or transition to sleet and freezing rain by Sunday evening and continue through the early overnight hours.

When it comes to winter storms, ice can be particularly hazardous. Not only is freezing rain challenging to forecast, but ice storms can wreak havoc on electrical infrastructure and vegetation, knocking power out for weeks and leaving roadways impassible. Travel becomes dangerous if not impossible, with roads becoming ice rinks.
