Breaking: Snow, ice expected this morning through Wednesday morning in DeKalb County

January 22, 2019

DeKALB – This storm could be nasty, with precipitation putting down layers of concerns for commuters today and Wednesday morning, according to a National Weather Service meteorologist.

NWS has issued a winter weather advisory from 9 a.m. today to 9 a.m. Wednesday, and Ricky Castro said at 8:30 a.m. there had already been reports of freezing drizzle to the west, in Whiteside County – so it could start here in DeKalb County any minute.

“The initial concern with this system will be the development of icy conditions,” he said.

He said more than one-tenth of an inch of ice is expected, but here’s the bugger – one of a few: It’s probably going to snow first, then turn over to freezing rain, then back to snow later this evening, creating a blanket of wet snow over ice.

“People have to go to work, but the big thing is to check road conditions and plan for longer travel times,” Castro said. “Use an extreme abundance of caution while driving.

“Anybody who can postpone travel or can work from home, we certainly encourage it.”

So, those other buggers? While temperatures are expected to reach the 30s around 5 p.m., that isn’t necessarily a good thing. First off, because we’ll be cloud-covered all day, the road temperatures will “lag,” Castro said, so freezing will persist. And the snow that falls overnight will likely be particularly wet snow, which will freeze when the temperature starts plummeting again around sunrise Wednesday morning.

“The potential is there for the storm to significantly impact both commutes – both today and tomorrow morning’s commutes,” Castro said.

All told, we’re expected to get between two and four inches of snow, although the northwestern part of DeKalb County could see more.

But wait, there’s more bad news: After the mercury dives below 30 degrees overnight, it isn’t expected to get back to 20 until Sunday. Thursday’s forecast calls for a low of 12-below, and a high of one degree is expected Friday.
