Yesterday we first told you about the chance for severe weather tonight and yet again on Tuesday. The storm prediction center has issued a slight risk for severe weather across the western half of the state. The main risks with these storms will be large hail, damaging winds, and locally heavy rain. If you are in a stronger storm, rainfall totals could approach one inch. There is even the possibility that some rainfall totals will be over an inch. Otherwise, rainfall totals will be between a quarter of an inch to a half inch.
Stronger storms will move out of Nebraska later on this afternoon into early evening. Storms will begin to enter western Iowa after 4pm this afternoon and will continue to push to the east. As they begin to reach central Iowa, the will begin to lose their steam as they will be losing the heating of the day.
After storms move out of the state by Monday morning, we will have a brief break from the rain before another round on Tuesday. This round on Tuesday will bring a chance of severe weather for the southern two thirds of Iowa. Highs Tuesday will be in the upper 70s to lower 80s with dew points in the 60s. A warm front will be lifting to the north from the south throughout the day on Tuesday, and this will spark afternoon thunderstorms. The main threats will be large hail, and a widespread damaging wind threat. There is the potential for isolated tornadoes but at this current time, the tornado potential is not the greatest threat. The greatest threat will be the widespread damaging wind threat. Heavy rain and the potential for flash flooding is also a significant risk. This threat will need to be closely monitored as there is the potential for an upgrade to a moderate risk in the coming outlooks. We will continue to keep a close eye to this forecast in the coming days and will update you on the very latest online and on our Facebook and Twitter pages.
