A winter storm warning is in effect in the region until Friday, extending as far north as northwestern Oklahoma, where up to six inches of snow is forecast.

Just more than one inch of snow had fallen in the Midland area, according to National Weather Service forecaster Douglas Cain.

Sleet and freezing rain were falling in San Angelo, according to forecaster Kelli Barendse, who said the total amount of snowfall will be affected by when the precipitation becomes snow.

“It really depends on when the wintry mix transitions over to snow, we’re anticipating late this morning or early this afternoon,” Barendse said.

No damage has been reported, both Barendse and Cain said.

In Odessa, Texas, in the Permian Basin oil patch, a winter weather shelter was opened that would be available through Friday. Federal guidelines for social distancing to stop the spread of COVID-19 will be enforced at the shelter, the city said.
