...Potential for Significant Rainfall Next Week...

An active weather pattern will continue next week across the
Midwest. Current indications are for two strong low pressure areas
to affect the area, first on Monday through Monday evening and
then on Wednesday through at least early Thursday. Plenty of
moisture will be available to both of these storm systems,
increasing the potential for heavy rain rates and significant
rainfall amounts with them. For the first system, confidence is
currently highest in rainfall amounts approaching or exceeding
one inch occurring along and southeast of Interstate 55, though
significant rain remains possible area wide. For the mid to late
week system, heavy rainfall is possible area wide depending on the
track of the low pressure area. Between the two storms, at least
parts of the area could experience total rainfall amounts of 2 to
3 inches or more. Given the saturated ground and ongoing minor
river flooding from the March 30th event, this potential heavy
rain could result in areal flooding of low lying areas and renewed
sharp river rises. Residents living in low lying flood prone
areas and along rivers and streams should pay close attention to
later forecast information.
