Now to the weather. A cold front will move south across Iowa around midday switching the wind direction from the SW to the NW. Here is the forecast position of the cold front Tuesday evening.
Temperatures will slowly warm into the teens by sunrise Tuesday and eventually into the low 30s by early afternoon. Not only will the wind direction change, as the front crosses, the temperatures will begin to fall in the afternoon as well. Late Monday night and Tuesday is going to be WINDY. Wind gusts to near 40 mph are possible. The wind diminishes Tuesday evening.
Clouds increase Tuesday night as we track low pressure southeast. Here is the forecast track.
Light snow will develop late Wednesday morning and spread southeast across eastern Iowa in the afternoon. Your Wednesday evening commute could be slick with about 1″ of snow. The snow tapers off before 10 PM Wednesday. Here is the probabilities for 1″+ and 2″+.
It should be a powdery snow since the temperatures will be so cold Wednesday…highs in the teens. A light wind is expected as the snow falls.
The next chance of snow will come Saturday afternoon or evening through Sunday. Early indications are that several inches of snow are possible with this storm. Exactly where that heavier snow falls is unknown this far out. The pattern is expected to start to change this weekend. When weather pattern goes through a change like this the models have a hard time in the extended forecast. We will continue to track the storm and have more details as the weekend approaches.
