Warm-humid air will continue to push into western and central Iowa this afternoon. Air temperatures are forecast to reach the lower 90s, with dewpoint temperatures in the low to mid 70s. This combination will result in heat index values in excess of 100 degrees, with a few localized spots possibly reaching 105 degrees for a brief period this afternoon. Warmest conditions will occur between 1-4 P.M. Limit outdoor activities if possible today. If you must be outside, take frequent breaks, and remain properly hydrated.
