Wednesday was beautifully sunny and cool, with the coolest max temp in almost 2 months (68.2 on July 21). But that was a rainy, cloudy day- the last rain free day in the 60s was a 67.1 max on June 5, a variably cloudy day. Overnight tonight temperatures will be dropping into the mid 40s, most likely our coolest minimum temperature of the season, coolest since late spring. Thursday should be sunny and a bit milder, with high temps in the mid 70s. Thursday night should be clear and not quite as cool, with lows in the mid 50s. Friday we should warm some more, with highs around 80. Saturday we should have some clouds around as a front approaches from the west, with highs around 80s and a 30 POP for showers during the afternoon and a 40 POP for showers on Saturday evening. Sunday should clear off with highs dropping down into the low 70s. Monday and Tuesday should see more nice, cool weather, with highs in the upper 60s and lows in the upper 40s. Moderating temperatures should follow mid-week, but no real organized storms of rain and wind in the foreseeable future. The first day of astronomical fall is coming at the end of this week, and it is definitely showing itself of late. No real leaf change around these parts as yet.

Currently the Eastern US radar screen is showing rain showers in parts of western Michigan- quite possibly instability showers from WNW flow off Lake Michigan - forerunner of the lake effect snows coming later this year - really sooner rather than later actually.
