Big changes are in store for the bi-state as a strong cold front approaches the area on Wednesday.
The morning commute in the metro will likely be dry, but a few storms are possible west of St. Louis back toward Mid-Missouri by mid-late morning.
Showers and storms increase along the cold front as it sinks southeast through the afternoon. The heaviest rain will likely be after the lunch hour on Wednesday.
Some embedded strong to severe thunderstorms will be possible, as the atmosphere will be marginally unstable and have enough wind shear to support stronger thunderstorm updrafts. This means some of the storms that develop in the afternoon could contain small hail and gusty winds up to 60 miles per hour.

Behind the front, temperatures will plunge into the 40s by daybreak Thursday. Cool, Canadian air will settle in with high pressure on Thursday and Friday, keeping high temperatures only in the low to mid-60s.
