Chicago records first snowfall of season – NBC Chicago

Chicago officially recorded its first snowfall of the 2022-23 season Monday morning.

The National Weather Service reported that O’Hare Airport saw snow beginning at 9:21 a.m., which “will officially be the first snowfall” for Chicago.

The weather service noted that while this is the first “trace of snowfall”, since a snowflake has hit the ground, it is not the first measurable snow.

“If snow accumulates to at least 0.1″ then this would officially become the first measurable snowfall, but it hasn’t happened yet,” the NWS tweeted.

So how early is it?

According to the NWS, the average date that Chicago sees its first traces of snow usually falls around October 31.

Snowfall at O’Hare International Airport on Monday means the city is two weeks ahead of schedule for the first snowflakes of the season, but it’s not the earliest on record.

The first trace of snow on record in the city occurred on September 25, according to the NWS, and the last occurred on December 5, 1999.

However, in 2021, Chicago didn’t see its first trace of snowfall until November 12. And, according to records, the first measurable snowfall – defined by NWS as a tenth of an inch of snow or more – did not occur. until December 28, 2021, the last first measurable snowfall in recorded history.

While Chicago may not see measurable snowfall Monday, two northwestern Indiana counties are under a winter weather advisory warning of the potential for up to 3 inches of snow.

Porter and Jasper counties are subject to the 4 p.m. notice Monday through midnight Tuesday. There, forecasters say a period of “heavy, wet, wind-driven snow” is possible Monday afternoon and evening, with some areas seeing up to 3 inches of snow, especially those away from Lake Michigan. .

But the advisory warns of some uncertainty surrounding the forecast.

“There is a higher than normal degree of uncertainty with the snow forecast,” he said. “If the snow is less intense than expected or remains to the east of the area, then little or no snow accumulation would occur.”

Either way, commuters in the area should be prepared for the potential for slippery and dangerous road conditions.

For those worried about snow accumulation, however, a combination of above-freezing temperatures and warm ground temperatures should ensure no snow accumulation occurs elsewhere in the Chicago area.

The NBC 5 Storm team said Monday will be windy and cold, with below-average temperatures in the low 40s and wind gusts of up to 35 miles per hour.

However, the wind chill will make things feel more like winter, creating a day that feels more like temperatures in the 20s and 30s. And, some areas may even see their first snow showers of the season.
