WINTER STORM WARNINGS, ADVISORIES NOW UP....

Winter Storm Warnings and Winter Weather Advisories have been posted now for the snow coming in tonight into tomorrow. The battle lines have been drawn...

Here's a look at the animation of the storm starting Sunday evening through Monday night:

There will be some rain around this today and tonight. Late tonight into early Monday morning there will be a transition to the wintry mix and snow (starting in eastern Iowa around 4-5 am). There will be some periods of heavy snow with this system as well.

Here's a look at some of the latest data.

HRRR:

Hi-resolution NAM:

NAM:

GFS:

Euro:

You can see there are still some differences in the models, particularly the HRRR going overboard and the NAM models showing lower totals around Highway 30. There are some uncertainties... when does the changeover happen, when does snow start accumulating (there will likely be some melting initially), and where does the band of heavy snow set up.

Here's a look at the National Weather Service showing ranges due to the uncertainty and the heaviest snow likely in northern Iowa:

Roads will likely get sloppy, slushy and slick during the Monday morning commute through about 3-4 pm. Thereafter, we'll be watching another storm system on Wednesday.

More updates to come as precipitation gets closer!

BOOK ENDORSEMENT.

*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!
