Monday morning weather update

I'm sure by now you've heard that it's going to be a hot one the next couple of days.  Temperatures over the weekend were in the 80's on Saturday and upper 80's/low 90's on Sunday.  Monday and Tuesday high temperatures are expected to reach the low to middle 90s with the heat index likely reaching the upper 90's.  While I'm not expecting those storms to move this far south because the upper level winds should take them over Lake Michigan, we will see a little extra cloud cover today than what we had yesterday.  Dew points, which are a measure of how much moisture we have in the atmosphere, will likely be in the middle 60s which will keep the heat index today in the middle and upper 90s.  Tuesday a weak cool front will slide through Wisconsin and down Lake Michigan and as it does moisture will likely pool, or collect, right along the front causing the dew point numbers to rise.  This will cause the humidity to rise as well. 


Heat Advisories and Excessive Heat Warnings have been hoisted for Minnesota, Iowa, Missouri and parts of the central Plains.  This is where the core of the heat will reside right under the ridge of high pressure.  There, the threat for storms or clouds will remain minimal allowing temperatures to rise into the upper 90's with the heat index values well over 100°.  Either way, coming off of several weeks of cooler than normal temperatures the late summer heat is something we haven't experienced too much of this summer.  Be sure to drink plenty of water and if you have to be out for a prolonged period of time try to take frequent breaks and wear light weight and light colored clothing.
