There will be a chance of thunderstorms beginning Tuesday night and continuing into Thursday night. There is also a low chance for strong storms over parts of the area on Tuesday night as well as locally heavy rainfall. Go to weather.gov/stlouis to get your local forecast.
Elevated fire danger is forecast across much of the area on Monday due to the combination of gusty southwest winds, low relative humidity values, and dry fuels.
Near-record heat will give way to showers and thunderstorms by midweek. A stronger cold front arrives late in the week with cooler, below normal temperatures.
Although frost is unlikely over the next week, we are approaching the time of fall that we commonly see our first frost and freeze. Plan ahead with the local fall frost and freeze climatology for select locations across the region. For more information, go to weather.gov/lsx/frostfreezepage.
