Red Flag Warning issued March 19 at 6:55PM CDT until March 19 at 7:00PM CDT by NWS St Louis MO

While winds will remain strong and gusty tonight, relative
humidity values are rising as colder air rushes into the region.
Therefore critical fire weather conditions are ending. Additionally
areas of light rain will overspread the region from the west.
This will help to raise humidity further through the evening.
