Some modest snowfall reports came in Saturday evening, mainly in the Cooper Country and Keweenaw. The highest report so far was of 3.8" in Mohawk-no surprise there! Mixed precipitation falling across the Upper Peninsula will eventually change to all snow from west to east overnight, even in the southern counties. Snowfall on Saturday night will amount to an additional 2-4" along on the higher terrain, west and the Keweenaw. Elsewhere, mixed precip will be slower to change to snow, and accumulation will be limited to an inch or less.
Winds shifting from the northwest and temperatures falling into the upper 20s/low 30s will keep things on the cool side into early Sunday. High pressure will slide just to our south Sunday. This means low level clouds will gradually break up, giving way to blue skies into our Sunday afternoon. Daytime highs in the southern half will reach the low 40s. Those northwesterly winds will keep temperatures more modest, in the upper 30s.
Then as quick as it came, that drier air will be gone by Sunday night. In fact, although some of our long-term weather models hint at warmer weather, it looks like we may continue to see a series of disturbances next week that will teeter between liquid and frozen precipitation. The first in that series will arrive late Sunday night with mainly snow. Depending on how much warm air is associated with that system, we may very well see some sleet and/or freezing rain mixing before dawn on Monday. Although limited snow accumulation is expected, we could see some slick roads during this time. Temperatures peaking well above freezing on Monday will allow a changeover to all rain by late morning/early afternoon on Monday. Rain will change BACK to snow Monday night! Tuesday looks dry for now. Then we'll be brushed by several disturbances for the rest of next week!
