Chicago can expect more unseasonably mild weather on Monday.
According to the National Weather Service, the city’s forecast includes sunshine and highs in the mid to low 50s to start the week, though storms could bring sleet and snow in the coming days.
“We definitely continue to be above average here. We are caught in this warm pattern,” said NWS meteorologist Kevin Birk.
Temperatures are expected to dip into the mid-30s on Monday evening while skies remain clear.
Warmth is expected to return Tuesday with a forecast high of 50 degrees, but possible afternoon showers and late-night showers will cloud skies, the NWS predicts. Strong winds are expected to gust up to 40 mph. Windy conditions are expected on Wednesday with partly sunny skies and a high temperature near 50 degrees.
A second storm system is expected for Wednesday night, bringing possible sleet to the area with snow on Thursday. NWS forecasters said highs would drop into the mid-30s.
Snowy conditions are expected to be roughly divided along I-55, with snow or rain and snow anticipated to the north and mainly rain to the south.
“Depending on the exact track, there could be some accumulated snow in Northwest Illinois and Wisconsin,” Birk said. The storm could affect central Illinois, but Chicagoans can expect “probably not much in the way of snow.”
Temperatures are expected to drop as low as 18 degrees with “thunderstorm” conditions on Thursday night and stay below 30 degrees on Friday before dropping back into the mid-40s during the day.
With an average high temperature of 35 degrees in mid-February, this week’s high marks once again hotter than normal.
“The February heat continues,” the NWS wrote on Twitter.
Still, Birk thinks the rainfall and storm system mean Chicago “could be active again” in the latter half of the month and early March, with the region’s weather possibly reverting to a cooler pattern.
“Beyond Monday, it’s possible that there could be further precipitation and cooler air, but it’s hard to say right now,” he said.
