The warm up has begun... and it felt great Saturday! Sunshine and temperatures in the 20s and 30s... the warmest we've been in two weeks. Here's a look at the high temperatures across the Midwest:

Sunday will be a mild day, but it comes with a side of snow. Temperatures will get an extra little boost from the storm system coming in:

And then snow moves in from west to east across the area Sunday morning through the evening. Here's an animation of the hi-resolution NAM model from 2 am Sunday to 2 am Monday:

This will be a quick-hitting system, but with how cold it's been lately the snow will accumulate on the roads as several inches fall. As such, the National Weather Service has issued Winter Weather Advisories.

Here's their latest snowfall forecast:

This is pretty consistent with my forecast and I'll show you some of the latest data. The hi-res NAM:

The HRRR (which is overdoing SW Iowa):

The GFS:

After this snowy bump in the road... the warm up continues as we head into the new week! High pressure will build in the upper levels of the atmosphere and will attempt to warm things up.

It will be fighting a deep snowpack so temperatures won't be as warm as they could be, but we should be near and above the freezing mark Monday-Wednesday:

The pattern does remain active and picks up again later next week. More on that tomorrow...

BOOK ENDORSEMENTS: *This book has been quite the talk with the Iowa State Library promoting it. I have never seen the State Library promote any books like this unless it was an award winner of particular interest to libraries. Hopefully your sales are through the roof! Jolene Kronschnabel-Director of Hawkins Memorial Library, La Porte City, Iowa *I ordered one of your Derecho books about the storm in Cedar Rapids, IA back in December. I love it! I had also bought one that the Cedar Rapids Gazette sold. Your book by far is so much better, you have a lot more pictures and it just tells more of the story. Thank you for putting a wonderful keepsake together! Do you have any left? If so can you tell me how to get at least one more. Thank you so much! Penny Brecke *911, IOWA'S INLAND HURRICANE-Great stuff! I couldn't put the book down and read it in one night! Lynn Taylor *Hi Terry and Carolyn! Thank you for my book, the kind dedication and wonderful job on the book warmed my heart!! Loved all the info-great job Terry! Carolyn the stories brought tears to my eyes. I have to admit it was difficult to read at first-reliving that day, but joy also with the way you wrote them in such good faith! We are living in town as our house is still gutted. Work is slow but progressing. The damage was far greater than we thought, but it will be glorious again one day! Love and prayer. Jenny Janssen *I received my book yesterday (just in time for Christmas). Thank you for all the hard work it took to put it together and trying so hard to get this book out. My husband will love it. Enjoyed your Christmas Video. Karleen Booth *Got the book today and am reading it now! Very well done. Thanks. Jack Wiley
