ST. LOUIS — Portions of the St. Louis area may see the first frost of the season this weekend. This is a little surprising, with temperatures near 90 degrees today. That’s just St. Louis weather. We will be going from 15 degrees above to 10 degrees below normal by Saturday. You will feel a real fall chill in the air this weekend.
Meteorologist Chris Higgins reports that a new cold front will approach the area Wednesday, with a good chance for showers and storms by Wednesday night. Following the cold front will be some much cooler temperatures later in the week. Daily highs will dip into the 60s with overnight lows in the 40s near the city, and some 30s in outlying areas by the weekend.
According to the National Weather Service, frost could develop if conditions are just right with clear and calm conditions. Some of the low valley regions of the eastern Ozarks southwest of St. Louis may see their first frost over the weekend. But this is not a concern for St. Louis.
