Evanston, August 17, 2018

Another very nice day. There was rain overnight and rain in the area, but no thunder so we, Jody, Bill and I, could swim. It was mostly cloudy and threatening rain, but the rain held off. No obvious wind. The surface water was still 76 but there was a very definite thermocline about a foot below the surface in many places, the water below was in the 60's. We suspect that this is telling us that our warm 70's will not be here long. But so far there is no confirmation from the Wilmette bouy.
