A Christmas Day storm could bring Colorado its biggest overall snow event in a month. Here's the chances of snow creating a white Christmas.

It's the first full day of winter, but it's not going to feel that way with daytime highs running well above normal. Sunday will be mild and dry with unseasonably warm temperatures. Daytime highs will reach into the upper-50s and low-60s which is 15 to 20 degrees above normal for this time of year.

Most of Connecticut will see a bit of a white Christmas with snow expected overnight into Tuesday morning, the weather service says.
