The seasons first snow likely later this week


    Light snow/flurries possible Thursday night.

    A preview of winter is on the way lasting into the weekend which includes snow chances and near-record cold by Saturday morning.

    Two waves of light snow are possible. One late Thursday night and another arriving Friday afternoon.

    The first will be tied to a storm system that will pass to the south in Missouri on Thursday. Eastern Iowa will be on the northern fringe of that system. Cold air will be in place and with just enough moisture there is the chance for light snow showers Thursday night. There will be a lot of dry air to overcome so it may be late evening or after midnight before any flakes start to fly.

    Minor accumulations of a dusting to a half inch are possible by Friday morning.

    A clipper system will then dive southeast into Iowa Friday afternoon leading to the chance of additional snow. The latest trend of weather models continue to shift the main snow axis further southwest.

    Considering the latest shift and between the two waves snow amounts of a dusting to an inch are possible with the highest totals in the far southwest.

    Minor accumulations are possible.

    There is still the possibility the axis of snow could shift further so that will continued to be monitored and updated if needed in future forecasts.

    Behind the snow the coldest air of the season will settle into eastern Iowa. Temperatures will drop into the teens Saturday morning and will be close to records especially if there is snow on the ground.
