Timing and Overview:
A freeze warning is in effect for western counties tonight. There is a slight chance of rain overnight for this area. Any rain that falls could lead to slick spots, especially on elevated roads, thus a Winter Weather Advisory may be necessary later tonight.
Very cold air moving into the region Sunday night and Monday will bring an increasing chance for freezing precipitation to the area. The primary precipitation type will be freezing rain as very cold, shallow air moves into the region overnight. Rain changes to freezing rain from west to east as temperatures drop to freezing and continue to drop. Ice accumulation up to a tenth of an inch are possible, with up to two tenths of an inch possible for the Victoria Crossroads. Sleet will likely mix in with the freezing rain Monday morning. Some light snow is possible north late in the event as well. Precipitation will decrease through Monday morning. Due to freezing rain being the main type of wintry precipitation expected, even small amounts of freezing rain can lead to big impacts in either Advisory or Warning situation. With that said, very dangerous travel conditions are likely Sunday night into Monday.
Overnight lows are expected to reach freezing temperatures area-wide starting Sunday night. Very cold temperatures are forecast Monday night through Tuesday morning, with minimum temperatures ranging from the teens across the northern Coastal Bend and Brush County to the lower 20s along the coast and Rio Grande Plains. This would result in a hard freeze across the region. Wind chills will fall near or below freezing as early as tonight, but dangerous wind chills of 5 to 20 degrees are expected Sunday night and Monday night.
South Texas Impacts:
Expected Accumulations: Accumulations up to 0.10 inch are possible, with up to 0.20 inch possible for the Victoria Crossroads
Impacts:
A hard freeze will have a significant impact on sensitive plants and pets. Elderly persons or your children could suffer hypothermia if exposed to a long duration of extremely cold temperatures. Exposed water pipes could break.
Dangerous travel conditions are likely as many secondary and elevated roadway surfaces will become slick and dangerous causing many vehicle accidents. Exposed outdoor objects, including trees, utility lines, and vehicles will become ice covered. Scattered power outages could last for several days.
Wind chill values of 20-30º starting tonight dropping to 5-20º Monday night through Tuesday morning
