NOAA's temperature map for June shows cooler-about normal-warmer weather for the U.S.
For the first two weeks of July here in southeastern Michigan, we are running more than 3° below normal... but we expect a brief warming trend this week before it goes back below normal.
My prediction is this year in Michigan will be below average overall ... at least around here. This may be part of a return to cooler weather trends caused by changes in the weather patterns which may be affected by changes in the Pacific Ocean.

Look for price increase in ethanol and Tostitos.
Of course, one benefit will be that we don't have to water the lawn anymore. Haven't done that once this year...
