ST. LOUIS, MO - Warmer temperatures are finally in the forecast for the St. Louis region, but so is a storm system that looks to bring a mix of precipitation to the area on Sunday. After sunny and cold Saturday, clouds return ahead of a warm front Saturday night. Temperatures dip Saturday evening before starting to rise again overnight. Light snow develops early Sunday then mixes with freezing rain and sleet by late Sunday morning as temperatures above the surface climb above freezing. The icy mix gradually changes to a cold rain Sunday afternoon and evening as temperatures climb before ending as wet snow and sleet late Sunday night or very early Monday morning.
Some ice accumulation is possible so travel could be dangerous. Ground temperatures are well below freezing so even after the air temperature warms to above freezing icing will be possible.
