Texas Snow?

Christopher Nunley

First off, I would like to apologize for the lack of updates as of late. As many of you know, I am super inundated with teaching, research, and wrapping up my PhD. With that said, I am enjoying every second of it.

I am keeping a close eye on cold temperatures and wintry precipitation chances for parts of the South from Wednesday afternoon through Thursday morning. An arctic cold front, which is currently oozing southward across central parts of the country, will move into the Southern Plains on Wednesday—and continue moving through southern parts of Texas on Thursday. This will usher in very cold temperatures—wind chills will be in the single digits and teens once the front moves through.

Thursday Morning Temperatures (NAM)

It is possible light wintry precipitation will develop behind this boundary during the day on Wednesday. The greatest chance will be across northern Oklahoma, southern Kansas, and northern Arkansas. A dusting to 1 inch is possible in these areas, but dry low-levels should limit higher amounts of wintry precipitation.

Another area of interest is parts of Texas late Wednesday into Thursday. An upper-level jet streak that will trek across Texas, which will aid in enough lift, combined with adequate mid-level moisture, to generate wintry precipitation.

The precipitation will start out as light sprinkles, then transition into snow once the atmosphere moistens and cools. Accumulations do appear to remain light at this time, but an isolated dusting to (at the very most) 1 inch is possible. The greatest chance for snow will remain south of I-20 in northern Texas, the Texas hill country, and parts of western Texas.

I will continue to monitor the latest guidance and have updates as needed.
