ROCKFORD (WREX) – Sunny skies to start this morning, but the clouds will slowly creep in.
Things remain dry, despite the fact that we will see that increase in cloud cover. The potential snow-maker that moves towards the Stateline overnight into tomorrow is already streaming cloud cover through the state of Illinois. Snow is breaking out across Missouri and Arkansas, where they are also dealing with a mix of sleet and freezing rain in spots.
Before diving into the details of the approaching snowy conditions, let’s discuss today’s forecast. Some sunshine is out there this morning, with cirrus clouds beginning to stream in from the south as moisture in the upper-levels begin to increase. Through the morning into the afternoon, clouds will continue to be on the increase, but we remain dry. Temperatures today rise into the 30’s in most areas.
It isn’t until well after midnight when snow showers begin to develop. Light snow will start first south and west of Rockford between 4 AM and 6 AM. Shortly after mid-morning, snow showers move into Rockford. As far as accumulations go, it looks like along Route 20, up to an inch of snow is possible. The closer toward I-80, the more likely snowfall of 2″+ is. There will be a very tight gradient between those that receive 2″ and those that barely see any flakes fly. Any shift in the track of the low pressure could alter these snow totals, so keep that in mind.
If you have travel plans toward central or southern Illinois, take special care to pay attention to the forecast. There are still details that are subject to change, particularly if the track shifts. Some spots could see close to a foot of snow.
Once we get past the brush with snowfall late-tonight into tomorrow, things dry out for Sunday with temperatures remaining several degrees warmer-than-average.
