This week is Severe Weather Awareness Week in Iowa and the featured chart looks at today's topic, Severe Thunderstorm Warnings. The chart displays the weekly frequency that at least one Severe Thunderstorm Warning was issued by the NWS per year. Four states are plotted for comparison. Iowa's season starts ramping up very late March and peaks mid July. Being the furthest north of the four states compared, it takes a bit for the really warm and moist air to reach us from the Gulf of Mexico. Severe Thunderstorm Warnings are certainly not too common during the winter months in Iowa as compared with the other states.
