Air temperatures in the 90s and dew points well into the 70s created for dangerous heat index values on Thursday. The featured map displays a grid analysis of maximum heat index values based on hourly NWS NCEP data from the realtime mesoanalysis. This product indicates a few places in Iowa reached 110+ degrees on Thursday and nearly all of the state over 100 degrees. The current near term forecast has a respite from the extreme heat and more frequent chances of rain.
