FIRST ALERT: Two Storm Rounds Expected Friday, Some Could Be Severe A storm system is set to bring two rounds of weather activity to eastern Iowa on Friday, with the potential for strong to severe thunderstorms. The National Weather Service has issued a First Alert Day due to the risk of dangerous conditions. The first wave of storms is expected to develop later tonight, following a period of dry and mild weather. A shift in air masses will introduce warmer, more humid, and unstable conditions, leading to thunderstorms near or after midnight. These storms will move northeastward, bringing heavy downpours, frequent lightning, and a small chance of hail, possibly reaching quarter-sized in some cases. The storm activity is likely to peak between 3:00 a.m. in western Iowa and 8:00 a.m. in the eastern part of the state. Showers and storms could linger into the early afternoon, though drier conditions are expected during the day. Unstable air will continue to build, providing additional energy for new storm development later in the evening. While the energy levels are modest for this time of year, they should maintain the risk of strong to severe storms. The second round of storms will develop in central and western Iowa by mid-evening, spreading into eastern Iowa between 7:00 and 9:00 p.m. The latest forecast data suggests areas near and north of U.S. Highway 30 may experience the strongest storms during the evening. These could bring damaging winds, large hail, and an isolated tornado. The duration of severe weather will depend on how storms evolve later in the evening and into the early hours of Saturday. If an organized line of storms forms ahead of a cold front, damaging winds could persist until around 1:00 to 3:00 a.m. on Saturday.#national_weather_service #kcrg_tv9 #us_highway_30 #noaa_weather_radio #kcrg_com
