The snow accumulation forecast for Arlington Heights and nearby communities is 7.1 inches; however, the combined action of “overperforming” lake effect snow could result in 9 inches of snow accumulation. The highest snowfall rates, associated with a Winter Storm Warning, are expected to occur between 2:00 p.m. and 10:00 p.m. Saturday, New Year’s Day 2022. Forecast snow accumulation totals have decreased about 1-2 inches since the Winter Storm Watch associated with the upcoming winter storm was issued Wednesday evening, but for populations closest to Lake Michigan, enhanced lake snow could bring snowfall accumulation amounts higher than the current forecast.




A Winter Storm Warning was issued Friday afternoon December 31, 2021 and continues to be active Saturday morning, and effective 12:00 p.m. Saturday until 6:00 a.m. Sunday CST.

There are seven primary concerns as the winter storm approaches …

1. Freezing drizzle may develop in far northeast Illinois, which could result in light icing on untreated surfaces. The icing period in Arlington Heights is forecast to last from 7:00 a.m. to 11:00 a.m. while picking up in intensity about 9:00 a.m. Northwest Cook County, northeast Kane County, most of McHenry County (east) and all of Lake County are forecast with the best potential for Freezing Drizzle Saturday morning.

2. There is a slight decrease in forecast snowfall accumulation totals, but hazardous travel conditions are still expected to develop this afternoon through late evening. The forecast for snow accumulation in Arlington Heights is 7.1 inches. Around 1:00 a.m. Saturday, the forecast snow accumulation was 9.3 inches. See #4 (below) regarding lake snow, which could leave us with more than 9 inches of snow anyway.

3. Gusty winds will create potential for some blowing snow — especially west and northwest of I-55 after sunset. Winds gusts ≥25 MPH are forecast for the entire day Saturday, and will exceed 15 to 20 MPH from 12:00 a.m. to 3:00 p.m. Sunday. Winds are forecast to peak over 30 MPH around 3:00 p.m.

4. There is uncertainty regarding the forecasting of the accumulation of snow from lake enhancement. However, snowfall amounts of 5-9″ amounts possible for far northeast Illinois have not been ruled out as of 7:45 a.m.

5. The arrival time of snowfall, currently 12:00 p.m., has trended later and the end time of snow fall has remained the same. Therefore, the duration of snowfall has shortened since the forecast from two days ago. Travel conditions are expected to degrade during early afternoon with about 2.5 inches of snow on the ground with gusty winds in Arlington Heights by 6:00 p.m. (for example).

6. The snow wetness has not been established in the forecast from the National Weather Service — only that the snow will be wetter in a gradient from far west Chicagoland to the lake shore of Lake Michigan. In other words, snow will be fluffier and drier west and wetter and heavier near the lake with a lower snow/water ratio near Lake Michigan. The snow will be wetter near the lake due to additional moisture available from the existence of Lake Michigan water temperatures that are on the warm side for this time of year. Therefore, the heart health risk related to overexertion with hand shoveling is higher, the closer the shoveler is to Lake Michigan.

7. Falling temperatures will drop to 22°F by 3:00 a.m. Sunday, 17°F by 8:00 a.m. Sunday, rise to only 19°F about 12:00 p.m. to 2:00 p.m. Sunday, and then drop the rest of the day to a low of 4°F from 3:00 a.m. to 8:00 a.m. Monday morning. Wind Chill is forecast down to -7°F at 8:00 a.m. Monday, January 3, 2022.
