2/18/2017 7:00 AM 0.00 0.0 M M M Great day yesterday! Another one on the way, but when..., will the other shoe fall! Chicago has a notorious tendency for significantly changing weather. The news media said we broke a temperature record yesterday (60 Deg in 1880), but the old record was taken down by the lakefront where it was much cooler yesterday. By my reporting station, it was not that warm. Away from the lake, it was significantly warmer, so the new record is false. How can you break a record at a location over 20 miles inland from one of the largest bodies of fresh water on the planet?!

7/28/2017 7:00 AM 0.00 0.0 M M M Just a beautiful morning. A bit humid, but it is July, almost August. My vegetable garden this year is the best I have seen in 10 years! With the late May, early June rains, I did not get plants in the ground until 14 June. Now, about a month or so later, I have 5-7 tomatoes on each plant, 2-3 eggplants per plant, almost ready to pick cucumbers, acorns squash, cabbage, and lots of peppers. All growing wonderfully!

8/12/2017 7:00 AM 0.00 0.0 M M M Beautiful August morning. Took our new puppy out at 6 AM for a walk, nice temps near Lake Michigan, and almost no breeze. PERFECT! I will have to remember this day in early January. Planted our garden late on 14 June due to the May/June Rains; My first tomatoes are red, harvested 3 eggplants already, several cucumbers, and our first acorn squash is ready! Best year in 10!

8/15/2017 7:00 AM T M M M M Light sprinkles fell several times after 7:30 PM. Enough at times to wet the ground, but all it did was raise the humidity more. Felt like a "Chicago Summer" of the 70's.

I was never able to grow a good beefsteak, now I have at least ten of them turning red and they are at least 2-3 pounds each.
