A strong winter storm will move across the country this week. Clouds will thicken Tuesday with some light snow arriving late in the day. Snow will switch to a wintry mix in the evening and overnight, and should turn to rain Wednesday morning. It will be wet the first half of Wednesday, but strong winds will bring much colder air and change the rain back to snow later Wednesday. As of right now, the timing may work out that there isn't much snow accumulation, but we shall continue to update the forecast frequently the next 48 hours.
This storm will produce heavy snow to our west (near and west of Chicago into the upper Great Lakes & midwest through the northern and central plains). Those with travel plans Monday night through early Thursday to points westward need to monitor upcoming forecasts. Blizzard-like conditions may affect parts of the northern plains by Wednesday with significant snowfall accumulations.
