A low pressure system will be placed in eastern Colorado by later this evening with rain increasing across Iowa 6-9 PM tonight. A decent slug of heavier rainfall will slide through the state overnight into Monday morning with the main axis of moisture extending from southwest through central and into eastern Iowa. Due to the heavy rainfall, ponding and localized stream flooding is not out of the question. Also need to watch south central into extreme southeastern Iowa early Monday morning for a few stronger storms that may contain some hail and damaging wind gusts. This activity will taper off across western Iowa mid-morning, central Iowa by late morning and eastern Iowa by early Monday afternoon. The numbers have been crunched for the system with rainfall amounts of 1-2" expected for a large portion of the forecast area and some locations on the lower end of that scale. I continue to think that a cut-off will be seen across interior northwest Iowa from 0.25-0.50" to 0.50-1.00" leading to totals that can underachieve in this zone.

In addition, we will have southeasterly winds sustained 10-25 MPH with gusts 25-35 MPH. Once Monday morning hits, the surface low will track over the southeast portion of Iowa with the wind quickly switching around to the northwest at 10-30 MPH with gusts 30-45 MPH. The wind will subside by late Monday night as the system works off to the east of the state. We are watching for a few different storm systems in the pipeline next week with more details to follow on that later.
