Pressure and weather in Lemay​

Lemay is in the south part of the St. Louis area on the west bank of the Mississippi, close to where the Meramec joins it.

Summers are hot and sticky, with clusters of thunderstorms. Winter can bring ice storms and heavy snow along the track of a strong low with pressure falling for a day or more.
