July skies in the northland are often changing as quickly as the weather changes. A nice day by Lake Superior can turn on you in a heartbeat. Within minutes, the temperature can drop by 20 or more degrees as the wind shifts around from the east off the lake. Even on an eighty degree day you need to keep a jacket handy for such occasions.
