I like this output from the High Resolution Rapid Refresh model that displays the snowfall from 4PM CST today to 5AM CST on Friday morning. It gives a good representation of where the heaviest snow is most likely to accumulate.
For tonight’s event they paint greater than four inches in the yellow colored area, mainly along and south of the Minnesota River Valley. Notice the expansive extent of the expected accumulating snow, which goes all the way down to Kansas City.
Poor travel conditions will be encountered tonight south and west of the Twin Cities. Snow is likely to continue falling along Interstate 35 into central Iowa Friday morning.
Good news, that should be of great joy to all the people, the snow is expected to exit most of the state by mid afternoon on Christmas Eve day. Look for seasonal temperatures for Christmas and Sunday.
Glad Tidings to you.
