Second, select specific chart options::
Plot Description:This application generates a map displaying the number of LSRs issued between a period of your choice. These are the preliminary reports and not official totals of events.
For plots that compare against an "average" value, the period of record is used (since 2002).
NOTE: If you choose a period longer than one year, only the "count" metric is available. Sorry.
Caution while plotting by county: The raw NWS LSR product text only contains a free-text name and state. The IEM attempts to use some heuristics to associate those with an actual political boundary. This fails about one percent of the time.
Based on a sampling of recent timings for this application, plot generation time has averaged 7 seconds. Hold on for the plot is generating now!
