WINTER WEATHER ADVISORY in effect through the morning drive until 9:00 AM Wednesday from St. Louis to the north. Pockets of freezing drizzle expected with a light glaze possible.
Tonight: Low 32. Patchy fog and drizzle, freezing in spots where it's cold enough creating patchy icy spots. We'll need to monitor roads closely through the morning drive. Especially on elevated surfaces like bridges and overpasses.
Wednesday: High 35. Mostly cloudy skies. Winds: North 5 mph.
Wednesday Evening: Mid to Low 30s. Watch for a round of light rain or light freezing rain depending on temperatures. Get an update on timing in case some freezing drizzle affects the evening commute, but current thinking is it will develop near or after 9PM into Thursday morning. best chance for ice is north of St. Louis, but a close call and worth monitoring.
