Winter starts with a chill in the air but milder weather coming for Christmas week

MILWAUKEE (CBS 58)--Finally, Mother Nature taking a cue with the calendar. Winter begins on Sunday, and it will be on the chilly side.  Highs only in the 20s. At least there's less wind today. A weak system will give us the chance of some light wintry mix on Monday.  Then another weak system will throw some rain showers in the forecast later on Christmas Eve, lingering through Christmas and the day following. Yes, it'll be warm enough for rain.  It doesn't look all day though.  More nuisance stuff. Highs on Christmas should be around 50 before becoming more seasonable into the weekend. Next weekend's weather still looks questionable. The computer models aren't in agreement. Stay tuned.
