The first fall cold snap arrived today with highs in the lower 50s, a brisk wind and some clouds, and tomorrow morning will be the coldest of the season so far with lows in the 30s and even a few 20s well inland and widespread frost. The chill continues through the weekend with highs only in the upper 40s to lower 50s on Saturday and some clouds and a NW wind at 10-15 mph. Sunday will have more sun, less wind and highs in the lower 50s, but Saturday night will be even colder than tonight with lows near freezing in Milwaukee and 20s inland. The fall colors are peaking two weeks early, and the first frost of the season for Milwaukee is also about 2 weeks early. The average date for Milwaukee’s first frost is October 17. Extreme northern Wisconsin will get 1-3" of snow tonight and a few flurries are possible Saturday morning as far south as the Fox River Valley, but no snow in Milwaukee.. However, Saturday is the anniversary of the earliest measurable snow in recorded history for Milwaukee with 0.1” back in 1889. We do get back to normal temps on Monday and Tuesday with highs in the lower 60s before another cold front drops us into the 50s for the rest of next week. Like it or not, fall is here.
