Rainfall is expected to soak the area Thursday. This, along with heavy rain that fell to the north, will result in rising rivers. You can monitor area rivers by visiting weather.gov/stlouis and click the Rivers and Lakes link near the top of the page.
Widespread rain will overspread the area from late tonight through Thursday and continue into Friday morning across the area. 1 to 2 inches of rainfall with locally higher amounts are possible, with the greatest amounts over parts of central and northeast Missouri and west central Illinois. This round of rain may cause rises on area rivers and streams into early next week.
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.
