Wednesday, July 14 was very tropical-like over east central and southeast Minnesota with monsoon-like rains and very humid conditions. A heat advisory was in effect for parts of central and southern Minnesota on Wednesday, July 14th as very steamy air moved into the state out ahead of a cool front over eastern South Dakota.

Dew point temperatures rose into the middle and upper 70's with a 79 degree dew point temperature at the Twin Cities International Airport at 1pm. This is the highest dew point temperature seen at the Twin Cities Airport since 78 degrees on June 26, 2007.
