Retirement news!

I’ve had an enjoyable 8 years as weekend meteorologist at MPR. It’s been great covering Minnesota and western Wisconsin weather for MPR News network listeners and Updraft readers.

I’ve forecast Minnesota weather since the late 1970s, with stints as a TV weather anchor and a radio meteorologist. I also owned and operated my own weather consulting business for 8 years. I am now retiring.

Thanks to all who watched, or listened to, my weather segments over the years!
