No not the Bob Seger song but it is now time to turn the page to June and the start of summer 2020. This will be a different kind of summer for me as this will be the first time since 1966 that I will not be working during the summer months (or it looks that way now) This week I will look at June and the meteorological summer.

It should be noted that “average” temperatures, rain fall and snow fall will soon be updated and the temperature will more likely then not be adjusted upwards. The same may happen to snowfall and rain fall as well.
