(National Weather Service/Dsm) — A storm system moving across the Southern Plains and lifting into the Ohio Valley will produce snow over Southeast Iowa today through Wednesday morning. Moderate to heavy snowfall is still expected across far Southeastern Iowa and parts of Missouri and Illinois. Strong north winds will cause blowing snow and reduced visibility in these areas, making travel hazardous. Winter storm warnings are posted for parts of Southeast Iowa with winter weather advisories for parts of South central to East central Iowa. The snow will end on Wednesday, with cool and dry weather expected for the remainder of the week.
