Here’s the Great Lakes and Lake Michigan satellite pictures from Saturday afternoon. Click the pictures to enlarge, or the links in the first sentence for full screen. In the picture, you can see that with a S to SSE wind, the lake-effect clouds were over the lake. You can see Torch Lake, east of Traverse Bay still has open water. Torch Lake is Michigan’s longest (19 miles) and 2nd biggest inland lake. It averages 111 feet deep and it’s deepest point is 285 feet. Compare that to Lake Erie with an average depth of 62 feet and a deepest point of 210 feet or the Great Salt Lake in Utah (the biggest salt water inland lake in the Western Hemisphere) with an average depth of 16 feet and a maximum depth of just 33 feet (the level of the lake varies a great deal). GRR reported 100% sunshine on Saturday. I was in Rockford during the afternoon and we had some high clouds in the later half of the afternoon, including some textbook “mare’s tails” cirrus clouds. The NWS also reported that from midnight to midnight, the average wind speed was just 4.7 mph. You can see there isn’t much snow down in Indiana. See what else you can see in the pictures.
The overnight model data rain developing Sunday PM from SSW to NNE across the area. The temperatures will be around or slightly above freezing when the rain starts. If you’re driving, keep an eye on the car thermometer. Keep in mind that even if your thermometer is reading a degree or two above freezing, the ground is cold and it’s not impossible that there could be a little ice forming. Even if that were to happen, it wouldn’t last, as temperatures will slowly climb to a high in the low 40s after midnight. Rain may total 1/4 to slightly over 1/2″ (the Euro.has 0.54″, the NAM 0.45″, the GFS is lowest at 0.19″ for G.R.). It’ll get breezy by evening and downright windy on Monday (gusts to 35-40 mph). The rain will change to snow and the models are printing on the possibility of an inch (2 at the most) of backlash snow. In any case, Monday won’t be the best day to be out and about. The models are confirming what I have suspected…that we’ll be cool for mid-month, with below average temperatures from the 15th to 17th.
