The next large area of heavy rainfall with this mighty storm will hit Michigan Saturday night and Sunday. Here is the general weather scenario we can expect.
We saw the first precipitation round. The next round of precipitation will develop overnight on Saturday night. Rainfall will spread overnight, with significant rainfall, especially when it comes to winter precipitation.
Here is the constantly updated radar loop showing rainfall on Sunday.
The main rainfall over night and Sunday morning should be icy rain. Another 0.25 to 0.50 ice accumulations are likely in all locations in the southern half of Lower Michigan. Late Sunday morning and Sunday afternoon, temperatures in the southern half of Lower Michigan should warm to over 34 degrees. This temperature level should help to melt some of the ice accumulation.
The northern half of Lower Michigan will get the same area of steady solid precipitation, but it will be a mixture of snow, sleet, and freezing rain. The mixture of precipitation will be on late Sunday morning in the direction of mostly freezing rain and sleet. Look for 1 "to 3" of snow and sleet, and 0.25 to 0.50 "freezing rain, temperatures may not warm enough to melt ice from trees and power lines, and salted roads may improve in the afternoon, but untreated roads will be an ice rink.
The upper peninsula will be in another round of heavy snow with occasional sleet, very heavy accumulations of 7 "to 18" additional snow are likely on the upper peninsula, traveling could be impossible in parts of the UP Sunday
Rainfall will be more sporadic on Sundays, but not all together will end, cooler air will recapture, and all precipitation will turn to snow.
Snow showers can be expected Monday and Tuesday Spotty, fast 1 "to 2 "Piles of snow are possible, but roads should be warm enough to avoid greater icing.
