Fairly Quiet, Brief Rain Or Snow Showers...

Good Morning!

Cloudy and gray to start here in South Central Michigan.  Expect a just a hint of very light snowfall or snow showers today.  We'll dive into some detail for you here, but let's have a look at the radar first to see what's going on:


As you can see, some precipitation is moving through the area.  What you see is very light rain or a wintry mix as long as you stay south of Ithaca and Saginaw.  My guess is quite a bit of that is not even making it to the ground.  North of that line, it's all snow.  A similar situation south, with a mix of precipitation possible, especially around Onsted and Jonesville.  Get a mask and some air on, time to take a deeper dive!

SUMMARY:  Cloudy skies today as a low tracks across north-central Michigan, touching off some light to moderate snow along and north of M-46.  South of that, snow showers or some rain.  The low exits the area during the evening hours, winds swing around to the northwest and pick up just a bit, then the fridge and freezer open up, allowing cold air in from Canada.  Temperatures drop 10-15 degrees across the board in the next 12-24 hours.  Gray and cold for the most part the next few days, then we get to next week, where we have a shot at some snow and possibly rain as well.  See my prior post for detail on that.  Clearing and cool for the middle of next week, then we cloud up and crank up what looks to be a fairly significant storm system near next weekend.

PRECIPITATION:  A little bit of rain or snow shower activity this morning and into the afternoon.  It'll be gone by the evening drive home.  Not much in the area, maybe a coating to an inch in the north zone of the blog, but I really think most of we do get will be liquid or freezing, so slippery roads as night falls are more of a concern.  As winds turn northwesterly off Lake Michigan, the lake-effect snow machine starts up, several inches of snow possible close in to the lake shore starting tomorrow evening.  I don't see that reaching this far inland, we'll check it once the low passes through and the winds shift.  We have to see how the wind field evolves before we start extending lake-effect snow forecasts inland.  In short, after tonight, fairly quiet through the weekend, unless you head west of US 131.

Here's a look at surface temperatures around the US at this hour, and a look at the infrared satellite image, showing the clouds swirling around the center of the low (look at the almost complete circle with Madison, WI near the center part).

Monday, a bit of early sunshine, then clouds increasing, milder, high 36.

Tuesday, cloudy skies, expect some snow showers, high 36.

There's a look at your forecast for the next six days, I hope you have a great day!  Blessings.
