Upwelling Sends Water Temps. CrashingAugust 13th, 2014 at 11:01 pm by Bill Steffen under Bill's Blog, Weather
Click on the graph to enlarge. This is a graph of the water temperature at the Port Sheldon Buoy which is about 3 miles to the northwest of Holland St. Park. You can see the water temperature was in freefall Tuesday as we had a fairly strong north wind that caused upwelling to occur. Warmer surface water was pushed away to the south and southwest as colder water from +100 feet below the surface rose to the top. The water temperature at the Ludington buoy had a drop of 18°. Here’s a graph of wave height from the mid-Lake Michigan buoy about 40 miles west of Holland. You can see how quickly the wave height increased (to 8.2 feet) and then subsided. The beach water temperature was 49° Weds. AM at Holland St. Park and just 53° at Grand Haven St. Park and Hoffmasteer St. Park. Inland temperatures are much warmer. The water temperatures Weds. evening of Reeds Lake in East G.R. was 74° (2-foot depth).
Also: Portland, ME, picked up 4.49″ of rain in 3 hrs…Updated total: 13.57” of rain fell in last 24 hours in Islip, NY, smashing the state-wide rainfall record, 8.94″ at Chester CT…5.7 magnitude earthquake in Chile Weds. everning…here’s Storm Reports from Weds. There was one tornado (in of all places, Washington State)…the largest hail fell near Meacham, Oregon…the fastest wind gust near Twin Falls, Idaho and a severe storm in Hidalgo, Texas along the Rio Grande River destroyed two mobile homes. I talked to a meteorologist from Brownsville, Texas once and he said they have a Severe Weather Watch about 4 times a year, that’s all.
