Colder Pattern – Slick Spots SundayJanuary 11th, 2013 at 12:59 pm by Bill Steffen under Bill's Blog, Weather
This is the GFS model run from Friday AM – valid for the morning of 1/22. Now it’s the GFS…so don’t get too excited if you’re a winter lover…but this is a real shot of Arctic air, complete with lake-effect snow showers and single digit temperatures. We do know that colder air will start to come in Saturday evening. A wave riding the front to our east will bring a period of mixed precipitation (rain, freezing rain, sleet and snow) to the area Saturday night (mainly after midnight) into Sunday AM. There will be some slick spots on the roads Sunday AM, beware of that. The cool air sticks around next week with temperatures back to normal January levels. UPDATE: The European has a major cold shot starting the afternoon of the 17th. We go to -25 at 850 mb and the temperature Friday afternoon in G.R. is around +7F. So…while timing is different…both the GFS and European have MAJOR cold shots for Lower Michigan…and…with the Lake Michigan water temperature still up around 40 degrees, we can expect at least snow showers, if not some more significant lake-effect snow. We’ll have at least a couple shots of at least light snow next week, so the ground will get white again. Catch me on TV for the latest. ALSO: Satellite images: Mt. Fuji with cap cloud, large mine sculpture “Lady of the North” from N. England and St. Peter’s Square on Easter Sunday.
