Live radar here – Numerous storms across the Great Lakes this Friday. They had lots of wind damage reports from the U.P., a 69 mph at Aurora, Illinois west of Chicago this PM out of a relatively small storm. Plainfield IL had small hail and 1.25″ of rain in 25 minutes. Houghton has picked up 1.32″ of rain since 11 pm
95 Thursday in G.R. The 3rd time this week we’ve reached 95 and the 5th 90-degree day in a row. It was 97 in Cadillac, 96 in Traverse City and 84 on the beach at Muskegon with a SW wind coming across 100 miles of water. Note the circulation in the image here…with the center of the heat bubble near Cincinnati. (satellite loop, current temperatures/weather obse11 PM rvations, Michigan weather map). The Lake Michigan water temperatures have reached their highest of the summer Thu. AM with 78 at both Grand Haven and Saugatuck, 73 at Mears. The winds, storms and northerly breezes will likely start to sent those temperatures down as we head into the weekend. Someone asked about Clean Air Action Days (formerly Ozone Action Days). None have been called during this heat wave. Here’s their website. Over the last few decades, many pollution levels have been going down, including CO2 emissions in the U.S. Read this. While CO2 emissions are going down in Europe and the U.S., they are soaring in China. The USA has already reduced its CO2 emissions/head by ~32% since its peak in 1970. Here’s a good article with lots of facts, data, graphs, references on the topic.
The Thurs. morning run of the NAM model (not the best model, but the first to come out) only gives G.R. 0.20″ of rain between 4 PM and midnight Friday (that looks underdone). It also does take us above 90 degrees tomorrow before the rain and it has southwest winds of up to 20 knots tomorrow afternoon – which could create a significant breakwater current at Grand Haven State Park tomorrow midday into the evening – don’t swim or jump off the breakwater tomorrow at Grand Haven. If you’re swimming at Grand Haven St. Park tomorrow (or the side of any breakwater open to a southwest wind) stay well away from the breakwater.
