Snowfall is coming tonight and could make roads slippery overnight. and tomorrow morning

ROCKFORD (WREX) – The No. 2 of 3 round for snowfall arrives tonight and packs probably the best punch. A few inches of fluffy snow could make the roads slippery overnight.

Tonight, in Tomorrow:

A fairly fast moving mower system moves tonight into the wee hours of Sunday morning. It’s not a very strong system, so the snow stays light in accumulations. The snow showers begin around 8 p.m. and are relatively light. Between 11 p.m. and 4 a.m. Sunday, we were able to see a moderate rate of snowfall, where an inch per hour could fall.

The greatest accumulations will occur south of the WI border where we may see accumulations between 3 and 5 inches possible. Snow is light and fluffy in nature, which means it accumulates a little faster than wetter, heavier snow.

It will also be easier to clean the driveway and sidewalks because it is so fluffy. Although the majority of the snow falls overnight, be careful with your evening plans if you go out late. Watch out for slippery roads.

Winter weather advisories will be in effect from 9 p.m. tonight until 6 a.m. Sunday morning for all of northern Illinois. This advisory is in place as the roads are slippery on the way. Drive very carefully and slow down if you have to go out late.

With snow falling before sunrise on Sunday, the rest of the weekend promises to be dry. Roads can be a little slippery in the morning where the plows haven’t been, so take it easy for church or brunch.

Round 3: Sunday afternoon to Monday

Another round of snow is possible late Sunday through Monday, this snow will be wetter snow compared to Saturday night’s snowfall. As temperatures warm up on Monday, the snow could turn into a wintry mix before dissipating by early evening. This system could bring an inch or two for snow accumulations.

Back to the freezer, let’s go!


Temperatures drop back below zero on Tuesday and Wednesday as another arctic air mass settles behind these clipper systems. High pressure dominates the Stateline for the day Tuesday and into Wednesday, so high temperatures will only reach the teens and low temperatures will hit the single digits below zero, a pair that with light winds , will result in temperatures of -10 degrees below zero or colder!
