Grand Rapids Thermometer Reading Too WarmAugust 3rd, 2014 at 4:27 pm by Bill Steffen under Bill's Blog, Weather
If you’re using the GRR thermometer for forecast verification, you’ve got a problem. Yesterday GRR had a high of 86°. Not only was that the warmest temperature around, but it was several degrees warmer than other close-by thermometers (81° Ionia, Fremont, 83° Kalamazoo, Battle Creek, Hastings, 79° Allendale, Sparta, Hudsonville and Sturgis. Today at 4 pm – GRR is 88°. The closest reading to that is 84° at Fremont. Both WOOD-TV here at Heritage Hill and GVSU downtown report 81°, Calvin College is 83°. This may be because the the dry weather as baked out the ground and grass around the weather station (best guess) or there could be a problem with the thermometer. In any case, I can’t forecast to verify for that thermometer, when it’s not representative of the area. Picture is from mid-afternoon at the Muskegon Channel, where the air temperature at 4 pm was 71.6°. Water temps. include 61° at Muskegon, 62° at Duck Lake and Saugatuck, 63° at Holland St. Park and 64° at Grand Haven. Watch me on the news tonight for the updated forecast (t-storms tomorrow).
