β An impressive low pressure system with its own cold air will dump over a foot of snow in the west Texas high country...
Winter Storm Ivy will deliver a hefty dose of snow to west Texas tonight into New Year's Eve, Thursday. While snow is not ucommon in this area, it still is surprising to see amounts over a foot. Highs are usually in the 50s in west Texas, but with a very impressive cold 500 millibar low, temperatures will hover around freezing at the surface. The upper levels are plenty cold for snowfall, so expect heavy snow late this afternoon through tomorrow evening.

Precipitation will begin late morning or early adternoon as a period of light rain. As colder air begins to move in, rain will begin to mix with freezing rain and sleet. Light ice accumulations can be expected. As the upper level low moves farther north and east into the panhandle of Texas into southwestern Oklahoma, the colder air will really dig in, and change any precipitation to snow. Accumulations will vary from a few inches to potentially 20 inches in the best axis of lift. 2020 goes out with a BANG for west Texas.
- π‘ Winter Snowfall Forecast
Show and hide layers π‘ The 2020/21 SWC Winter Snowfall Forecast illuminates a wintry picture over a large portion of America. A La Nina favored large-scale pattern with upper-level ridging in the west and troughing in the east was considered in developing this forecast. Other influences, from the Arctic to the North Atlantic, could play a major role on how storm systems progress across the country.
