UPDATE: for the latest information and forecasts, click here.
Light snow began falling in parts of our area overnight as a major snowstorm, expected to bring a one-two punch of snow to the area, moved into the region.
We won't see much accumulation Sunday night into Monday. However, the second half of the storm is when the real damage will be done as the storm could intensify enough to bring 18 inches of snow or more to parts of the region.
A fast-moving Alberta clipper moved in between late Sunday and will last into the Monday morning commute - dropping 1 to 3 inches of snow during the day Monday. The second part of the storm will bring major accumulations.
