The biggest impact from these waves of rain will be the potential for excessive rain. Multi-day rainfall totals will be heaviest in a band from southwest Missouri into central Missouri where six inches or more could fall. Totals in the St. Louis area will range from as low as one inch east of St. Louis to as much as four inches west of St. Louis.

Most of this unsettled period will be in the form of non-severe storms. However, we need to watch a line of storms Monday night that could produce some stronger wind gusts.
