Thursday in a post I mentioned that a clipper disturbance might catch the northeast parts of my area with some snow as it digs southeast. Recent runs have been digging and tracking the system further and further west and now it looks like the southwest half of the region has the best chances for snow and the northeast may miss out altogether.

This is where the NWS in Des Moines showed the highest threat of snow late Thursday. Well, things change and now we have a different scenario.

To give you an idea of how fast things change, this is what the afternoon run of the 3k NAM looked like for snow.

The night run just 6 hours later shows a significant push west of the heavier snow taking much of my area except the far south out of the snow band. I don't like to see swings like that at the last hour.
