ROCKFORD (WREX) — Light snow started up early Wednesday afternoon, and won't quit until after sunrise Thursday. As temperatures drop below freezing, snow starts to stick to the roads.
Early in the storm, temperatures stayed at or above freezing, preventing the snow from sticking to the roads. Temperatures fall into the teens by Thursday morning. We may see some slush on the roads as a result.
Once we get beyond midnight, snow showers become light again, or even down to just flurries at times. A second wave of light to moderate snow is possible around sunrise. This may cause roads to get slushy or snow-covered again during the Thursday morning drive. Plan on slippery spots on the roads in the morning. The showers wind down by 8 am, with a dry and very cold day after that.
As for amounts, the Stateline stays on the lighter end of the storm. We didn't see snow as early, and won't get the heavier snow for as long as other areas nearby. In general, 1-3" of snow looks to pile up once the showers end Thursday morning. The higher end of that range will be along and south of I-88.
Further to the south and east, 3-6" look possible. This includes DeKalb and Chicago, so if you have to head in that direction Thursday morning, keep in mind you may be running into a lot more snow-covered roads and slippery conditions. Snow may linger as late as noon closer to Chicago, which may prevent clean roads for a while in those locations. Winter Weather Advisories highlight where travel conditions may be treacherous.
Once the snow ends, Arctic cold invades for Thursday and Friday. The weather stays dry during the extra chilly stretch, then warmth returns this weekend. We have a chance at additional flurries on Saturday. Next week, the weather warms enough that rain showers may fall on Monday, then change back to snow by Tuesday.
