ST. LOUIS -- Temperatures remained below freezing across the St. Louis area overnight as a wintry mix moved through the region from the west and southwest.

Although road crews spread salt to battle the mixture of freezing rain, sleet and snow, driving conditions across the region could still be hazardous. Untreated surfaces will be glazed with ice and even treated surfaces may see some icing as temperatures drop into the upper teens and lower 20s by daybreak Sunday

Mostly snow fell farther north and west of the metro area with a mix of freezing rain and sleet for most of the metro. Farther east and southeast, it was mostly freezing rain creating a dangerous glaze of ice.

Winter weather advisories remain in effect into early Sunday morning for the entire 5 On Your Side area.

Total accumulation of snow will be from one to two inches farther northwest of the metro with a dusting to a half an inch of sleet and snow expected for most of the metro after a bit of a glaze of ice. In the areas south and east that see mostly freezing rain, up to .15" of an inch of glaze is possible.
