Most Recent Observation

This application displays the last observation received by the IEM from this site. The time stamp is in America/Detroit timezone.

This station reports observations in SHEF format. The following two tables break these SHEF reports into recently made reports and those older than five days ago. The IEM's archive of raw SHEF text products is only five days, so thus why the Product links are only for the first table.
