Cold air gripping much of the United States will stick around, at least for our part of the country. Saturday will be cold, temperature-wise and wind chill-wise. After starting off in the single digits, high temperatures will be half of what they should be for early December. Our forecast high for Rockford is 18 degrees; our average high for December 7th is 36 degrees! On the positive side, ample sunshine will take us through the day thanks to high pressure. Clouds will thicken up Saturday night, keeping temperatures somewhat tolerable in the lower teens. Sunday will be a mostly cloudy day with a high near 25 degrees. A system that will bring snow to California will merge with a piece of atmospheric energy in the Rocky Mountain states. Our cold air combined with moisture lifting north from the Gulf of Mexico will all come together with this system and bring some light snow to the Stateline.
Light snow should develop during the afternoon hours of Sunday, with accumulating snow in the evening and nighttime hours. A few lingering light snow showers and flurries may pass by during the early hours of Monday morning.
When it’s all said and done, 1 to 3 inches of snow accumulation is possible. The higher totals will be near and north of US Route 20 and especially in southern Wisconsin. Parts of central Wisconsin and Iowa may pick up 2 to 4 inches. -Joe
