WEST MICHIGAN — While temperatures on Sunday are expected to reach the upper 20s/near 30, it will be extremely short-lived. Another Arctic blast will plunge in to Michigan, but this will be a little different from the last one.
First, the air won’t be quite as cold as before, although single digits/teens are expected for highs. It also appears as if the winds will not be as strong as before, which means wind chills will be running below zero, but probably not the 20 to 30 below we experienced before. That said, the cold blast will set up shop a little longer (from Monday through Thursday) before moderating back to around 20 on Friday.
The other good news? We are not expecting another 6″-12″/12″-18″ snowfall like last time. We have several chances through the next several days for accumulating snow, but we’ll probably nickeled and dimed throughout the week with a few inches from time to time here and there. It will come from both lake-effect/lake-enhanced as well as system snow as weak disturbances ride through the upper flow across the Great Lakes.
Take a look at the GFS computer forecast model temperatures below. This would be the air mass temperature at about 850 millibars, or around 5,000 feet above the surface. The map is valid for Wednesday morning and shows temps at -22 degree Celsius (about -7.6 F), which will equate to only 10 to 15 degrees at the surface (note the maroon color). While the forecast models aren’t showing heavy lake-effect snows at this time, ample moisture coupled with weak disturbances can change that as we move a little closer, so stay tuned to later forecasts!
