Unusual cold and a potent storm is combining to bring more snow, icy weather and travel hazards from New Mexico to Texas and Oklahoma through Sunday.
Friday's slick travel over parts of the Southwest and southern Plains was just a preview of what is to come for the remainder of this weekend.
The treacherous travel will unfold through Sunday as accumulating snow spreads eastward across New Mexico, western Texas and western and central Oklahoma.
Worsening the situation for motorists will be an icy mix preceding the snow.
The snow will total 3 to 6 inches in Albuquerque, N.M., and Amarillo, Texas, and around 3 inches in Lubbock, Texas. Between 1 and 3 inches is expected in Oklahoma City, Okla., and Abilene and Midland, Texas.
The icy mix and snow will wait until Sunday to reach Oklahoma City.
While the same cannot be said for the accumulating snow, ice pellets will spread eastward to Tulsa, Okla., and Dallas and Austin, Texas, on Sunday. That is especially true in the afternoon.
San Antonio will narrowly escape the wintry weather, but will still be dampened by a chilly rain through Sunday.
The snow and icy mix threatens to cause treacherous travel on Interstates 20, 25, 27 and 40. Even stretches of I-10 through West Texas will turn slippery.
Those traveling by foot should also watch for slick spots on untreated sidewalks, while airline passengers--including those starting their Thanksgiving vacation early--may face delays.
Residents should prepare for possible disruptions to weekend plans.
Sunday night through Monday morning, the icy mix and travel hazards will center on central and northern Texas and surrounding areas. This zone encompasses Oklahoma City and Dallas and stretches eastward to Shreveport, La.
Setting the stage for the wintry weather is the unusual cold gripping the nation's south-central states.
Temperatures on Sunday throughout New Mexico, Texas and Oklahoma will be held 20 to 30 degrees below typical late November highs.
Temperatures will fail to climb out of the 40s on Sunday in Brownsville, Texas, where the normal high this time of year is in the upper 70s and a stretch of highs in the upper 80s occurred this past Wednesday through Friday.
Drier weather and a rebound in temperatures will finally grace the southern Plains by midweek, just in time for the busy Thanksgiving travel day of Wednesday.
