Chicago is under a winter storm watch, as the city expects the first major snowfall of the season.
Meteorologist with the National Weather Service Chicago Kevin Doom said Sunday night he expects additional lake effect snow to move down the lake and steer toward the Chicago Metro.
"We expect the snow within this band to be very heavy snow rates, maybe upwards of two to three inches per hour, so very heavy snow," he said. "In conjunction with that, some pretty strong winds, which will even worsen visibility."
Doom said the heaviest impacts are going to be around the bend of Lake Michigan.
"We're probably going to see some pretty hefty totals, but on more of a widespread basis, as opposed to a localized, really heavy snowfall," he said.
He said this means travel conditions Monday morning will likely be rough.
"There's a good chance that we could have completely impassable roads, near white out conditions, especially when you tag on 30 to 35 mile an hour gusts during the morning," he said.
He said this includes aviation as well.
"If you have a flight planned, it's likely going to see some pretty heavy snow at the airports, at least for a portion of the morning as well," he said.
He reminds people to have their travel plans figured out before heading out the door.
"I'd really advise you to avoid travel if you can," he said. "If you have to travel, maybe just wake up a little bit earlier tomorrow, give yourself some extra time. Assume that conditions are going to be bad."
