The first “significant” winter storm to affect the Chicago region is scheduled to start Monday night, with meteorologists predicting 2 to 5 inches of snow accumulation and wind gusts up to 30 mph across portions of central and northeast Illinois and northwest Indiana.
A winter weather advisory goes into effect at 8 p.m. until noon Tuesday in the Chicago metro area as well as in parts of DuPage, Will and Lake counties.
Ricky Castro, a meteorologist with the National Weather Service in Romeoville, said the city will probably see about 2 to 5 inches of wet snow during the advisory. Temperatures will hover around freezing, at 31 to 39 degrees, throughout this period.
“The snow’s going to develop later this evening, overnight, and be heavy at times, and probably produce some winter travel impacts to the commute tomorrow,” Castro said.
The storm will likely be split into two rounds, according to the NWS. The first will arrive this evening starting around 8 p.m., with much of the snow accumulating in a brief window from 1 to 5 a.m., just before the early morning commute.
Snow rates may exceed 1 inch per hour during this round, the NWS said. Officials also warned that slippery road conditions could greatly increase travel times Tuesday during the morning rush hour.
“Leave plenty of extra time if you have to drive,” Castro said. “If you have the ability to work from home, if you have that flexibility, that’s not a bad idea.”
The city Department of Streets and Sanitation is planning to send out more than 200 salt spreaders to make sure conditions on DuSable Lake Shore Drive, bridges, overpasses and other roads are “safe and passable” for vehicles, according to a news release from the the city’s Office of Emergency Management and Communications.
The city urged drivers to have a full tank of gas before heading out on the roads, yield to emergency vehicles and snow plows when driving and to carry an emergency kit with a cell phone charger, food and water. Overnight parking bans are also enforced on more than 100 main streets in the city from 3 a.m. to 7 a.m. until April to allow enough space for snow removal.
By Tuesday midmorning, snow will fall mainly across northwest Illinois. Castro said temperatures could warm in the Chicago area at this time, leading to a possible change of rain instead of snow.
The NWS said minor snow accumulations and gusty snow showers are possible Wednesday night and Thursday night. A potentially “more significant” system approaches Friday night, with a winter storm.
Due to a strong El Nino, scientists predict that Chicago’s winter will be milder and drier than normal. Castro said it’s been a mild winter so far, with Monday’s storm shaping up to be the first “noteworthy” storm this season.
Conditions at 8:30 a.m. at Midway Airport are overcast at 34 degrees.
