Two weak systems have come together and induce surface low formation. This surface low will likely move just south of our area tomorrow, and this will provide the first widespread accumulating snow of the season for Southeast Michigan. There will likely be two different rounds of snow with this system. The first will occur as the surface low passes just to our south. This round of precipitation will start in the mid-morning timeframe tomorrow, and will continue until about rush hour tomorrow evening. This precipitation may start off as rain, but should quickly turn over to snow. Total accumulations for this first round of snow will likely be in the 1-3" range. Dry air will then work into the area late in the afternoon tomorrow, which will stop the snow for a while. However, a second round of snow is then likely to occur starting early Tuesday Morning as wraparound moisture and a favorable NNW wind off of Lake Huron will combine to send lake-enhance snow showers into our area. These snow showers will likely be heavy at times, and will probably give us at least another inch of accumulation, maybe even two. Due to this I am forecasting Lake Orion to receive 3-5" of snow with this system. This obviously won't be enough for a snow day, but it will be our first real accumulating snow of the season.
My forecasted accumulations between 8 a.m. Monday and 8 p.m. Tuesday
