ST. LOUIS — A prolonged period of active weather will start to unfold Saturday evening and continue through at least midday Tuesday. Multiple rounds of rain and thunderstorms are expected through that period.
It will not be raining the whole time. The most likely times for rain will come late Saturday night into early Sunday morning, with much of Sunday being rain-free. Then more waves of rain Sunday night through early Tuesday.
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.
