TENNESSEE VALLEY (WHNT) – While everyone is putting the finishing touches on their holiday plans today, wrapping the last of the presents, a classic Winter Storm is taking shape out to our west, which could bring severe weather and snow to the Tennessee Valley Christmas Day and Wednesday.  Before we get consumed with Christmas Day, let’s talk about Christmas Eve, showers continue to track east and will gradually exit the region from west to east this afternoon as a weak cold front moves through. Clouds are expected to hang around for most of the day, though a peek or two of sunshine is not out of the question.

If you have plans for this evening, expect cool and cloudy, but quiet conditions, with temperatures cooling into the mid to upper 40s through the evening.  Overnight temperatures will drop off into the low to mid 40s.

As you wake up for Christmas Day and start to unwrap presents, expect dry conditions. Since we have entered a more active weather pattern over the past few weeks, we have had a few chances for severe storms, but those chances never really materialized due to lack of instability/moisture.  A critical component for severe weather to develop is moisture surge ahead of the storm system to fuel storms.  If moisture is not there, then it doesn’t matter how dynamic a storm system is, storms will not develop.  This is the main question mark for the potential for severe storms Christmas evening and night across the Tennessee Valley.  As you might expect, the closer you are to the coast, the greater the moisture and therefore there is a higher potential for severe storms across central, southern Alabama, stretching westward into Mississippi and Louisiana.
