What was reported inside it

Time	Report	Where	Remark
Jun 27, 10:00 PM CDT	Thunderstorm Wind 0	Mckenzie, ND

NCEI Storm Data entries that began inside the alert's area while it was in force. Before 2003 the local storm report archive is thin, so this is the record of what happened rather than what was phoned in. Storm Data before 1996 records only tornadoes, thunderstorm wind and hail.
