Despite some brief early afternoon snow, it appears temperatures could reach as high as 32 degrees in the county Thursday, which would be the first time in three weeks the high got at or above freezing.
If the high does reach 32 degrees, it would be the first time in more than three weeks that the area has been at or above freezing, according to National Weather Service meteorologist David Beachler, using information from the Marengo data site.
Beachler said McHenry County has a "pretty close shot" of getting to 32 degrees today, but could not be certain due to increased cloud cover throughout the day.
"With clouds rolling in, it's going to be a little more challenging," he said. "But we are adding more minutes of daylight, so we'll see more of the sun."
The last day Marengo saw temperatures at or above freezing came on Jan. 21 when the high was 35 degrees, Beachler said.
"It's not necessarily uncommon to have these stretches (of below freezing temperatures)," he said. "But overall, as a winter itself, we've definitely been much colder than usual."
This winter is on pace to be one of the coldest on record. The average high this winter has been around 24 degrees, with the average low of 4.3 degrees, according to National Weather Service data collected in Marengo. The historical average high is 31 degrees with a low of 14 degrees. The coldest average high temperature for a winter was 22 degrees in 1935.
There is a chance for temperatures to reach the 40s by the middle of next week, but not before a potential light snow accumulation on Saturday and a possibility for freezing rain on Monday, Beachler said.
