Day 5 30% Risk

Posted: 28 Mar 2023 05:30 AM

It is Severe Weather Awareness Week in Iowa, so it seems fitting that a significant severe weather event is forecast for Friday. Based on yesterday's forecast, the Storm Prediction Center has a chunk of southeastern Iowa highlighted for a 30% risk of severe weather at forecast day five. This is a high probability at a forecast time of five days out and something that happens only a handful of times each year. The featured map shows the most recent year a given location was under such a forecast risk of severe weather. This map does not directly show this, but this is practically the first such 30% risk for Iowa at day five since 2015 (the start of this threshold's archive). Much can certainly change by Friday, but it is a good week to prepare for the worst and follow along with the awareness week at hand.
