Sunset on Lincoln Lake Weds. evening from Pamela Newman. We have 3 dry and pleasant days coming up. Low temperatures this Friday AM included 43 at Baldwin, 41 at Houghton Lake, 39 at Grayling and 37 at Leota in Clare Co. (after a high of 81 yesterday). Through Thu. 8/22, Grand Rapids is 3.4 deg. cooler than average for Aug. and cool nights will keep us below average today and tomorrow. It’ll be hot next week. We’ll make up a good portion of that, but we’ll still end the month a little below avg. for temps. There could be some isolated fog in the early morning. Temperatures will be near 80 this afternoon, low-mid 80s Saturday and upper 80s on Sunday. The overnight run of the European model gives G.R. only 0.04″ of rain next Weds…that’s it out to 7 days. The ACE Index, a measure of both the number and intensity of tropical storms/hurricanes is at it’s lowest annual level for this date since 1988. We have had 5 named tropical storms, all weak and short-lived. Because of satellites and air recon., we name storms that never would have been named 50 years ago. From July 24-Aug. 19, the Continental U.S. had 2,899 record low temperatures and 677 record high temperatures. Keep in mind there are thousands (tens of thousands) of weather stations now than we had 75 years ago and they have varying lengths of record. A weather station with data only going back to 1980 would have missed the heat of the 1930s or the cold winters of the late 1970s. Some heavy rainfall totals: Richland MI is up to 6.35″ of rain for August. Peru, IL had 3.08″ yesterday, 6.47″ fell southeast of Daytona Beach FL and 2.93″ fell in 45-minutes just north of Colorado Springs. Yesterday was the first day since July 17 that the high temperature in Los Angeles (LAX) was warmer than average (77 vs. 75). The cool water off California is responsible. The 77 yesterday was the warmest high temperature since July 12th. The 80-degree temperatures at LAX on January 20 and 22 were warmer than any day they’ve had since an 81 deg. reading on July 1. The warmest temperature at LAX this year was 90 on May 3rd. The average high temp. at LAX goes from 64 in early Jan. to 75 in late August…only an 11 degree difference between winter and summer. Storm chasers could see some big thunderstorms across the U.P. and at least northeast Lower Michigan next week. The dry weather from G. R. north has caused some leaves to turn brown and fall. We always get a little of that in late August, but dry conditions accelerate that. I’m still concerned about a mid-late September frost, a little earlier than average. This dry air (low dew points) air allows for significant temperature falls at night and the nights are getting longer. We are losing daylight now at the rate of 2 1/2 minutes per day.
