The weather pattern is slowly transitioning to winter. Colder air is filtering into the Midwest and Plains and eastern North Carolina should have a glancing blow from the chill. Most of the colder air will stay to our west but we should see cool afternoons and chilly nights for the remainder of this week. We'll see a warming trend by the end of the weekend followed by another blast of chilly air by the middle of next week. The colder air will come and go over the next two weeks. A prolonged period of cold air is unlikely through the middle of December as there is nothing to lock it in place. Consequently, near normal temperatures with oscillating cooler and milder periods can be expected through mid-month. Most of the area missed a White Christmas by one day last year. I'll take a better look at the overall pattern we get closer to the holiday season in a couple of weeks. I'm sure some of us would like to see that White Christmas.
