First snow could come overnight
Earliest trace of snow occurred Sept. 23, 1928
MADISON, Wis. — Southern Wisconsin could see the first snowflakes of the season late Friday night or early Saturday morning.
News 3 meteorologist Haddie McLean said cold air will sink southward out of Canada throughout the day Friday, and temperatures will fall to the middle 30s overnight. Scattered light rain showers are expected to redevelop later Friday and continue Friday night. Temperatures will be cold enough aloft that some flurries may mix with the rain.
Areas north and northwest of Madison have the best chance of seeing snowflakes Friday night.
Any rain snow mix will diminish Saturday morning, but it will remain chilly through the rest of the day with highs only in the middle to upper 40s. Normal highs for this time of the year are in the middle 60s.
The earliest trace of snow in Madison occurred on Sept. 23, 1928 with the average first trace of snow occurring on Oct. 25. The earliest measurable snow happened on Oct. 6, 1964 when a half-inch of snow fell.
