Wintry mix might arrive tonight, but a post-Christmas storm could bring heavier snow

Precipitation may return on Monday night — Christmas Eve — in Nebraska and western Iowa, but the chances for heavier snowfall come later in the week.

A low-pressure system is expected to lift out of the Texas Panhandle, according to the National Weather Service office in Valley. It’s possible that enough cold air will be filtering in on the back side of the system to produce light snow, mainly north of Interstate 80, on Monday night. Areas along and south of I-80 could see some light freezing rain by early Tuesday.

“Monday night, a little weather system could possibly bring a rain and snow mix,” said meteorologist Cathy Zapotocny. “A more significant storm system is heading this way Wednesday through Friday. The big thing is for people to be aware of it, because it will be a big change from the weather we’ve been seeing.”

Above-normal temperatures were expected to continue, with afternoon highs in the low to mid-40s through Tuesday. Forecast models generally show chances for snowfall increasing though the region this week.

On Sunday, the potential for the heaviest snowfall accumulations remained focused on portions of northeast Nebraska.

“But the storm system is still too far away for accurate predictions,” Zapotocny said. “Monday or Tuesday we’ll have a lot more data.”
