This is the overnight run of the European model for Monday evening. Click the image or click here to enlarge. Sandy moves right on top of New York City, cold north wind in Michigan. Check out this animation of Sandy, making the loop on the East Coast. This is the GFS – huge area with damaging winds, heavy rain. Heavy snow in mountain areas of W VA and PA – snow to the NE Carolina. This image was tweeted out by Dr. Ryan Maue of WeatherBell. The center of Sandy is over Chesapeake Bay. The counter-clockwise circulation is quite large and brings a north wind to Lower Michigan. Initially, the air is dry and the wind moves from NW today (Fri.) to due North…so the wind will not be coming off Lake Michigan…so no lake-effect and a dry weekend. Eventually, as Sandy comes northwest, we’ll pick up clouds and some rain. It’s not impossible that there could be a mix, but with temperatures near to above freezing and a warm ground, we shouldn’t get accumulations. The European (which appears to have been the best model on Sandy so far), gives G.R. another 0.70″ of rain from Tues. night to Thurs. night. The GFS has only 0.05″. The GFS would have a chance of light rain, a chilly NNW wind and about 40 degrees for trick-or-treat. We have had at least a trace of rain on 19 of the last 24 days and measurable rain on 15 of those 24 days. We are up to 6″ of rain for the month in G.R. and over 7″ in Holland and Saugatuck. Interesting note – yesterday the average wind was 16.1 mph and that made it the windiest day since mid-April. We haven’t had a lot of really windy days of late. We had record highs of 76 in MKG and 78 in G.R. on Thurs. It made 80 at the Regional Airport in Holland. There were 5 wind damage and 2 severe hail reports in northern Wisconsin Thursday. Northern Lower Michigan and Eastern Upper Michigan should get some snow from Sandy. October rainfall so far: Holland 7.35″, Muskegon 6.67″, Grand Rapids 6.07″, Kalamazoo 4.76″, Battle Creek 4.68″. The average high/low for Grand Rapids is 56/39 today. We continue to lose daylight at the rate of nearly 3 minutes per day. Partly to mostly sunny this afternoon.
