Chance of ShowersOctober 20th, 2013 at 4:17 am by Bill Steffen under Bill's Blog, Weather
Monday PM - Jim Leyland retiring as Detroit Tigers Manager. Still a few sprinkles, mainly east of a line from Battle Creek to Lansing. With quite cool (for this time of year) air coming over Lake Michigan, expect the clouds to hold and a few lake-effect showers (mixed sleet) will likely develop. We had a couple flashes of lightning around Muskegon/Grand Haven with the showers overnight. - With this pattern, there is always the chance of a random waterspout on Lake Michigan. Cold air coming over relatively warm water produces bigger waves than warm air coming over cold water…so it’s best to stay off the breakwaters most of the time when we have a pattern like this. The models have temperatures in the 40s by late today and we may not see 50 the rest of the week! The European has G.R. getting a little below freezing early Weds., Weds. night, Thurs. night and Fri. night. 850mb temps (about 5,000 feet above ground) go to -4C by Monday evening and stay between -4C and -7C until next Saturday. The model is probably not catching the warmth of Lake Michigan (at 60F), but the contrast from the water to less than a mile above will be very significant. There is the potential for some significant sleet and even snow with a pattern like this and even (if ground temps. reach the upper 20s and it can snow hard for awhile) slippery roads. Stay up with the latest forecasts this week, we’re definitely in for some interesting late fall/early winter weather this week. Check out the links below:
