Posted: 17 Sep 2013 05:44 AM
The featured map presents the IEM computed percent of average number of
tornado and severe thunderstorm warnings issued per NWS forecast office
for the year to date. The average is computed for the same year to
date period over the years 2003 to 2012. Most of the Iowa forecast
offices are below average for warning counts, except LaCrosse. The
largest positive departures are out west with some offices 200% of
average. The southeastern US is generally below average with many
offices below 50%.
