Tornadoes, wind, hail, and snow all possible on Christmas

TYLER, TX (KLTV) -

Now that I have your attention we have a very complex weather system heading towards East Texas tomorrow that will cause a wide range of weather across our area. Christmas will start off cool and rainy with embedded strong storms with our southern counties warming into the lower 60s around mid morning. As this happens, we could see a few tornadoes develop in the stronger storms before much colder air moves in behind our cold front.At this time, especially across the I-30 corridor, rain could mix with or change to snow. So here is how it looks to unfold right now.

Around 3 a.m., a warm front will begin to move north across Deep East Texas. To the south of this front, very warm and humid air will spread across the area. The big question right now is how far north this front will move. Right now it looks as though it will move as far north as a Palestine-to-Rusk-to-Carthage line around noon.

Along and south of this line, scattered surface based thunderstorms will develop, capable of ingesting air from the surface. It is here where there will be a threat of high winds, hail, and tornadoes. The atmosphere is set up to where there could be a strong tornado in this area, so if you live in the region please pay close attention to the weather through at least midday on Christmas.

North of the warm front, there will still be a threat of severe weather south of a line from Canton to Jefferson. Here the thunderstorms will be what we call elevated; meaning the air they ingest is not from the surface. This makes the tornado and wind threat very low but there will still be a large hail threat. Right now it appears the stronger storms in this area will be capable of producing quarter-sized hail.

Areas north of a line from Canton to Jefferson, it appears mainly a cold rain will fall across the area with a few embedded thunderstorms. The overall severe weather threat appears fairly low here, but there could be a few storms with small hail.

Once the area of low pressure moves to our east during the afternoon hours, cold air will sweep into to East Texas. This is when we could start to see rain mixing or changing to snow across the I-30 corridor shortly after 3PM. If there is enough moisture, we may see a few snow showers as far south as I-20 but right now it does not look too likely.

This is a developing weather situation and the forecast will change a bit as we head through tomorrow based on the exact track of the low pressure. If it moves farther north, much of East Texas will be under a risk of severe weather and tornadoes. If it moves farther south, then most of East Texas will be spared severe weather, but many areas could experience snow.
