Sunny and dry but then cold weather hits and possibly snow
Many Chicagoans are likely to don sunglasses as Thursday gets underway. The morning’s abundant sunshine represents quite a change in a month which has seen just 28% of its possible sunshine.
Even more significant Thursday is the absence of rain. Rainfall totaled 0.64” at O’Hare and 1.14” at Midway. The final round of rainfall with the second autumn storm to sweep the Chicago area Tuesday night and Wednesday was just hours from winding down at this time 24 hours ago.
There’s a chill in the air Thursday morning. Overnight readings have dipped into the 20s away from the city and the “warmth” of Lake Michigan’s low-50° waters. And even chillier temperatures are predicted Thursday night. Mid-20s are likely at the coldest inland locations by daybreak Friday.
But early indications point to an outbreak of the season’s coldest air to date next week. Temperatures then could register the lowest readings seen here in nearly 7 months.
The possibility of some snow or mixed precipitation is being monitored for Tuesday, and in areas closest to Lake Michigan, possibly into Wednesday as well. These are preliminary indications and not yet carved in stone. We’ll keep you posted.
