Michigan had some significant issues with heavy rainfall earlier this week, as dams stressed by the new rainfall failed northwest of Saginaw, near Midland and Edenville, forcing thousands to evacuate. Hopefully, a couple of days of calm quiet weather are on their way, and Michiganders can dry out and put things back together.
At 1053AM, ET, Detroit was reporting a temperature of 65 degrees with mostly cloudy skies. At the surface, things were tranquil with high pressure in the area, but an upper level low churning over Kentucky and Tennessee is smothering the region in clouds and an unusual southeasterly flow across Michigan. A result of this is that warmer temperatures are found north of Detroit, while it gets a bit cooler to the south.
The low is cut off from the primary flow in the region, which is coursing through central Canada. The feature approaching Appalachia will have no direction, save to attempt to drift towards a jet trough in northern Quebec. The circulation in the eastern Midwest won’t drum up much energy in Michigan, but moisture will probably be persistent in the mid and upper levels, suggesting mostly cloudy skies to begin Memorial Day weekend, though the low level moisture shouldn’t be available to lead to much rain, though drizzle will be possible. Expect some dreary times and temperatures not reaching their potential, but certainly not a terrible start to the weekend.

My original draft had no precipitation in the Detroit forecast, but then I got cold feet, because they have a local source of moisture just to the east. Still, it’s remarkable to see precipitation forecasts all over the map like this. Should be an interesting verification. Let’s check out this satellite image, with clouds smothering the area just south of Detroit.
