ROCKFORD (WREX) — A storm system cut off from the jet stream will spin its gears over the Stateline, giving us a couple days of snow.
The showers remain light, so accumulations won't pile up much and impacts remain low through Friday morning. Friday evening to Saturday morning could get tricky, however, as heavier snow may pop up toward the end of the storm.
Through Thursday evening, light snow falls almost continually. We may see 1-2" of snow by the end of Thursday.
The milder air in place may help cut down on the net amount of snow. We'll be above freezing Thursday afternoon, which causes some of this new snow to melt. Same goes for the roads. The milder road temperatures may melt the snow faster than it can pile up. Since we are close to freezing, road salt works much more efficiently, helping keep roads clear of snow and ice. That said, untreated roads and side streets may get a little slushy at times. Be careful driving if you see snow sticking to the roads, especially Thursday morning.
We'll repeat this process Thursday night into Friday as the storm continues to spin overhead. Another 1-2" of snow is possible. The Friday morning commute may get a little slick on side streets and untreated roads. A little rain may mix in with the snow by Friday afternoon, and temperatures rise above freezing again. This helps cut down on the new snow piles.
The storm picks up in intensity starting Friday evening through Saturday morning. Another couple inches of snow may fall, and could fall fast enough to pile up before the road can melt it. Friday night could be our best chance for snow to stick, so adjust your plans accordingly. We'll keep you up to speed as we diagnose whether the heavier snow lines up over the Stateline, and how much could fall as a result.
Snow showers wrap up Saturday morning. We'll stay dry and above freezing during the day over the rest of the weekend.
