Some relief is in store today for northern Minnesota, while central and southern Minnesota see the mercury rise into the 90s accompanied by high relative humidity. Heat index values will surpass 100 degrees again this afternoon from around Morris, Minn., through the Twin Cities into Wisconsin.


High temperatures could top out above 100 degrees in far southeast Minnesota and Iowa. Light winds today will offer little relief from the oppressive conditions. Avoid being in the direct sunshine from mid morning through mid afternoon.
