Ice Storm Warning Counts
17 Dec 2024 05:30 AMThe freezing rain event this past weekend prompted the National Weather Service to issue an Ice Storm Warning for much of eastern Iowa. Among the warning types issued for Iowa, the Ice Storm Warning is one of the least frequently used. The featured map presents the number of such warnings by county over the period of record, which dates back to around 2006. Freezing rain setups require the juxtaposition of warm air aloft and freezing temperatures near the surface and the surface low pressure track between the two, so southeastern Iowa is certainly a bit more favored for such setups than other portions of the state. It is interesting to note the two northeastern Iowa counties (Howard and Chickasaw) without a single such event, again since at least 2006 (the advent of programatic event tracking by the NWS).

Ice Storm Warning
02 Jan 2023 05:34 AM2023 is getting off to an active start with the National Weather Service issuing an Ice Storm Warning for much of northwestern Iowa. The featured map presents the most recent year that a given county in Iowa was under such a warning. The IEM's database only goes back to 2008, but the Ice Storm Warning is one of the rarest headlines issued in Iowa by the NWS. This map indicates that four counties have not seen such a headline over this period.
