Drier air has filtered in from the north and shut off precipitation to most of the D/FW Metroplex. Road conditions are looking good and the worst stayed off to the south and to the east (Canton and points east, Corsicana and south). Very chilly conditions will continue today with temperatures in the 20s and wind chills in the single digits and teens.
Get Texas road conditions at drivetexas.org. Road conditions, especially bridges/overpasses in Austin, San Antonio, east into the Brazos Valley, and Southeast Texas will go downhill this morning. Travel is discouraged if possible
The freezing line currently extends from Eagle Pass to Brackettville to Uvalde to the south side of San Antonio to Victoria to El Campo to Brookshire to Humble to Cleveland to just north of Jasper. This freezing line (the 32F degree line) will continue moving south this morning.
Ice is being reported on elevated roads and bridges in Austin, Cypress, the Woodlands, and Conroe. Expect bridges to become icy in San Antonio and the northern half of Harris County over the next sixty to ninety minutes as light to locally moderate freezing rain/sleet continues.
Light to locally moderate snowfall continues to fall in East Texas this morning. Interstate 20 is in bad shape from Canton into Lousiana with Interstate 30 a mess from near Mount Vernon into Arkansas. One to three inches of snow accumulation has been reported. Snow should taper off over the next two hours north of Interstate 20.
Patches of light freezing rain, mixed with sleet at times, is expected to continue in Central Texas and South-Central Texas through 9 AM. As temperature profiles continue to cool we may see a switch to a light sleet/snow precipitation mode. Light accumulations are possible, but anything that does fall will only continue to cause road conditions to deteriorate in the Austin and San Antonio metros; and across the region. We’ll see precipitation start moving off to the south and east of Central Texas by the late morning to early afternoon. Temperatures will not get above freezing today.
Ice is already being reported on elevated objects just north of the Houston metro as of this writing. Considering the event is just beginning in Southeast Texas that doesn’t bode well for bridge conditions in the coming hours. Patches of light sleet will continue through the morning across Southeast Texas. As temperatures continue to fall we’ll see minor accumulations, especially on elevated surfaces. Expect elevated roads and bridges to ice up in the Houston metro in the next two hours. Expect the freezing line to make it to the coast later this morning. Light sleet may mix with or switch over to light snow by late morning before precipitation becomes move isolated this afternoon.
The High-Resolution Rapid Refresh model is indicating a secondary band of light precipitation this afternoon across South Texas, the Middle Coast, and the Coastal Plains. This light rain will switch to light freezing rain/light sleet as temperatures fall below freezing in portions of South Texas, the Middle Coast, and the Coastal Plains. A thin layer of ice may accumulate on elevated surfaces. Bridges and overpasses could become slick and hazardous in places like Freer, Corpus Christi, and Rockport by late morning and into this afternoon.
