The weather graphs are interesting. What is causing the fluctuation in temps during daylight hours? Is it the sunshine dimming and brightening through the various density of clouds as they pass? But then, what would affect the dew point fluctuations?
I went back and looked at the wind charts. Since the winds were light and variable both days with partly cloudy sky, the brief fluctuations in temperature can be attributed to passing clouds or the shadow of a mature con-trail, especially since there was no onshore/offshore Lake Michigan breeze component involved. The Lake Michigan onshore/offshore breeze component is usually quite dominant here and can cause temperature fluctuations as much as 10' F or more several times a day when landmass winds are from a slight westerly component to either 180 or 360 degrees. Concerning the dew point fluctuations---the dew point dropped because the temperature dropped while the amount of moisture in the air stayed the same. The per cent humidity would go up, if it could be measured for such a brief interval.
I have the exact same weather station (that I got for Christmas) but I'm waiting for some time and a nice day to set it up. When that happens, you'll be able to go on line and see all my weather conditions.
