MINNEAPOLIS -- We're dealing with record dew points this week all across the state.  We tied our all-time state record of an 86 degree dew point on Sunday in Madison, Minnesota.  The previous record was in St. James and Pipestone in July of 2005.

The Twin Cities tied its all time highest dewpoint of 81 degrees Sunday night at 9 p.m. and then trumped it Tuesday at 3 p.m. when the dewpoint hit a tropical 82 degrees.  The previous record prior to this week for the Twin Cities was in July of 1999. Both of those dew points occurred after rain had moved through allowing even more moisture to pool in the atmosphere.

Tuesday at 2:30 p.m. we tied for the highest heat index at Minneapolis-St. Paul International Airport, reaching 118 degrees. The last time it felt like was July 11, 1966. At 4pm in Eden Prairie we reached 120 degrees for the heat index.

Another day of high heat and oppressive humidity is on tap for Wednesday. Hang on, a brief respite from this stretch of heat is on the way.

Temperatures will creep towards the century mark Wednesday afternoon along with tropical dew points in the 70s and potentially a few low 80s. The humid air will push the heat index into the dangerously high 110-115 range.

Later Wednesday night, a few possibly heavy thunderstorms are possible ahead of a front which will be rolling through triggering our cool down.

This will set the stage for more comfortable air with much lower humidity and somewhat cooler temperatures on Thursday.

But by Thursday night, another warm front will push through bringing dew points in the 70s with isolated t-storms likely on Friday. July certainly is living up to it's reputation as the warmest month of the year.
