Wintry weather will impact parts of western Texas this weekend, which may cause a few travel issues for parts of I-10 & I-20. A potent upper-level low will move out of northern Mexico into western Texas on Saturday. This upper-level low will generate strong lift, leading to the development of precipitation. This precipitation will fall in the form of snow across western Texas due to the cold air mass in place.
Moisture is minimal with this system, which will limit the snow potential; however, enough moisture is in the atmosphere to allow for a few inches of snow. The heaviest snow will fall in the Big Bend of Texas where up to 4″ may fall. The best timing for snow will be early-Saturday morning continuing into the early-afternoon hours.
Snow may impact travel, thus, a Winter Weather Advisory is in place for this region. Parts of I-10 & I-20 will be impacted by the snow. If you have any travel plans along these Interstates, prepare for icy conditions.
