Records Fall Before Temperatures Crash

***Watch WISN 12 News for the latest weather information!***

Thank you for stopping by the Weather Watch 12 blog!  Record heat gripped the Milwaukee area for a second straight day.  The high heat will stick around one more day, before temperatures take a nose-dive to end the week.

Temperatures sizzled across southeast Wisconsin on Tuesday.  The official high in Milwaukee at Mitchell Airport was 97 degrees!  This broke the previous record of 95 set back in 1933 for June 7.

The high of 97 was significant for many reasons…

  • Record high for June 7
  • Hottest June day since June 16, 1994(100 degrees)
  • Hottest day since August 1, 2006(97 degrees)
  • Tied for 8th hottest day in the past 20 years

Record to near record heat will hang around again on Wednesday.  Highs will generally top out between 88-94 degrees across the area.  A lot will depend on how morning showers and t-storms track.  If you remember Monday, the showers and storms made it into southeast Wisconsin.  As of this writing I think there is a small chance of some morning showers or a t-storm, best bet in western or northern counties.

Assuming the morning round clears and allows in some hazy sunshine, another record high is possible in Milwaukee.  Record high for June 8 is 93 set in 1933.  But again a lot will depend on the morning convection, where it moves, and also how many clouds hang around.

The heat is one concern for Wednesday, the second is the potential for strong to severe storms.  The Storm Prediction Center has outlined southeast Wisconsin as an area that could see severe storms occur.  Main threats would be large hail and strong winds.  Below is the map, with the yellow area showing the slight risk.

Severe Weather Outlook Wednesday

The timing of the potential showers and storms looks to be in the later afternoon or evening.  Below is the RPM forecast map at 7pm Wednesday.  This model, one of many we look at, shows strong storms pushing through southeast Wisconsin.  We’ll keep a close eye on the storm potential for Wednesday, and if any turn severe we will give you updates on WISN 12, and here on 

RPM Surface Forecast Wednesday, June 8 

As the cold front passes, winds will shift to the northwest, and by Thursday morning the north-northeast.  This shift in the wind will drop temperatures into the 60s inland by midday Thursday, and potentiall as cool as the 50s lakeside!  Below is the RPM temperature forecast at noon Thursday.  Yikes!  That is cool in Milwaukee!

RPM Temperatures Thursday June 9

Highs will likely be stuck in the 50s for a good part of the metro on Friday assuming some clouds, showers, and east winds hang around.  The cooler weather will continue into the weekend.

  1. Big change for Thursday, but not unprecedented. Often these early season heat waves come to a very abrupt end–one extreme to the other. Tonight would be a perfect Summerfest night. Please save some of these for 3 weeks from now.

    • Patrick,

      Hopefully Summerfest gets some nice weather. The severe threat tomorrow lines up with April 19(most of that stayed in IL), and also November 22 which hit parts of SE WI. November 22 was 1 degree shy of a record high. So this part of the pattern did produce warm temps once. With the jet farther north now I should have seen at least a warm-up for this period. Likely would not have seen the mid 90s though:)


  2. Had a brief thundershower move through the Lomira area this morning (Wed.) about 6:20 AM. It was accompanied by some hail. Fortunately it didn’t last long.

  3. Thursday, June 9, 2011 7:01 am

    Rainfall report: As of 7am, 0.80 inches.
    Storm report: No damage of any particular significance in my immediate location. Was a rather strong gust front from the storm. Not real confident about my estimation, but I’ll say it was in the 45 – 50mph range.
