A wind chill advisory is in effect for northern Iowa tonight and tomorrow morning. Wind chills will drop to -20 to -30. You can see the counties in the advisory are shaded in light blue.
The NW wind will gust to over 30 mph. We will have dangerous conditions for all who might be caught in the cold tonight.
There is also a chance for light snow Thursday. This will allow for little more than a dusting. There could be some slick roads...but much of that will come from the melting today and re-freezing after sundown.
A more potent storm is setting course for Iowa Friday. There is a good chance for 1 to 3 inches of snow in Des Moines. Right now the forecast is showing more snow in northern Iowa...but if the storm track moves to the south we could see additional snow.
This is the more active weather pattern we expected at the beginning of the season. La Nina usually means a peaceful start to winter...but more significant storms for the second half of the season.
Looking ahead... there is a stronger storm that is brewing for next week. This one looks like it will be in the area Tuesday and could have rain/freezing rain and snow. It is far too soon to give an accurate measure ...but is one to certainly watch.
Stay warm and make sure to check on pets and those who are not able to stay warm.
