An Alert Day is in the forecast for Friday night and Saturday. Accumulating snow is likely through the period. Right now, it looks like snow totals will range from an inch or so northwest of Dane County to up to 4 inches elsewhere. There may be locally higher amounts of 5 or 6 inches in a few spots.

Skies will become mostly cloudy tonight as a cold front moves through southern Wisconsin. Temperatures will fall to the middle 30s by late evening; overnight low temperatures will fall to the lower 30s by morning. This same cold front will slow down it’s movement as it heads southeast. A deepening area of low pressure will move along the cold front through Illinois from later Friday into Saturday. This means we’ll likely see a rain snow mix developing Friday afternoon, with highs into the upper 30s.

The mix will change to snow on Friday night with some accumulation by Saturday morning, with the heaviest amounts likely to be over southeastern areas. Saturday will be mostly cloudy, windy, and colder with snow tapering to flurries in the afternoon from west to east; additional snow accumulations are possible, again, with the heaviest accumulations more likely southeastern areas.

Dry air to the north of this system will lead to a very sharp cut off in totals on the northern edge. As a result, total storm accumulation will likely range from around an inch northwest of Dane County, to around two to four inches in and around Dane County. Farther south and east, a wintry mix could linger a little longer, which may cut into totals, as a result, the range is for a trace to 4 inches there.
