* from this evening through late Sunday night
* Recent rainfall has set the stage for a significant flooding
event this weekend. A slow moving and potent storm system will
interact with a very moist airmass to produce heavy rainfall
over the weekend. Rainfall totals of 3 to 5 inches are likely
with locally higher amounts possible across southeastern
Missouri and southern Illinois.
* Heavy rainfall will result in flooding of low lying or poor
drainage areas…and ultimately dangerous flash flooding on
smaller creeks and streams. Moderate to major flooding is also
possible on larger streams and rivers.
