A powerful pacific storm system moved across the plains and great lakes region later Thursday night through Friday unleashing heavy snowfall and strong north/northwest winds with gusts of 30-50 MPH which led to blizzard conditions Friday 1/12 through Saturday 1/13. Heavy snow moved into the state from later Thursday night into Friday morning with snow continuing to fall across Iowa. Eventually this activity began to taper off from west to east by Friday afternoon. Heavy snowfall rates of 0.5-2.0″ an hour occurred across central and southeast zones in the pre-dawn hours of Friday.
This resulted in a widespread swath of 6-12″ of snow across the central and southeast half of the forecast area. The highest amounts were across extreme southeast Iowa near Davenport where upwards of 14-15″ was seen with the system. Strong surface winds with ongoing blizzard conditions continued through Saturday evening for most zones before the system finally moved off to the northeast. This was a forecast that came with some headaches but overall, a good snowfall forecast to close an extremely active stretch of weather.
