St. Louis forecast: Near record high temperatures Monday

Above average temperatures expected all week

ST. LOUIS — Sunshine will be the rule for the next few days with clear, mild nights.

Winds out of the south will tend to keep temperatures higher than average overnight. Southwesterly winds will bring near record heat to the St. Louis area on Monday.

Monday and Tuesday will be much above average with highs at or just above 90°,. Monday's record high temperature is 92° set just a couple of years ago in 2019 and is in jeopardy. Humidity levels will remain reasonable as the temperatures climb.

While the trend will be for temperatures to drop a few degrees by midweek, the overall above average pattern will continue into next weekend. That means September will end up nearly three degrees above average for the month. 

There is not much of a chance of rain over the next week based on what we are seeing right now. There is a small chance for a few showers by Thursday and again over the weekend, but widespread significant rain doesn't appear likely anytime soon. October looks to begin with above average temperatures and below average rain chances.
