THE FLAKES ARE FLYING....

The cold moved in and then the flakes started to fly. Snow showers and flurries moved through Iowa and Illinois during the day Saturday. Some accumulation occurred in spots, including in Waterloo, Iowa:

This is pretty impressive, considering 36 hours prior the temperatures were near record highs in the 60s and 70s.

There may be flurries around Sunday but more sunshine is likely. It will be another cold day:

Monday will be dry and cloudy but slightly warmer:

The bump up in temperatures will be ahead of a disturbance that will move in late Monday into Tuesday:

This will lead to slick conditions on the Tuesday morning commute. Here's a look at the snowfall projections on the Euro:

And the GFS:

The NAM, timing is a little later Tuesday into Wednesday:

There's still uncertainty on the timing and the intensity. There may be two systems between Monday night to Wednesday that lead to the accumulation.

Definitely looking like more accumulation and the potential for 1-3" of snowfall.

We'll keep updating you on the latest trends, but here comes winter!
