Monarch Butterfly Migration Update: June 17, 1997
Why was May so cool--and the monarchs so late? According to meteorologist Ken Barlow of the Minneapolis Star & Tribune, the jet stream remained in its fall and winter mode right through the month, and brought persistently cool weather throughout the country. It has now finally shifted into its spring/summer mode.
Today's report includes 46 new sightings. If you still have not seen--or reported--your first monarch, please do so today! We will post a final migration update on July 8th, along with a map summarizing this spring's migration.
