Recent warm winter weather, commonly associated with a La Niña weather pattern, will usher in colder temperatures and possible moisture during the upcoming weekend.

Jennifer Stark, head meteorologist with the National Weather Service in Pueblo, said Colorado has been in a "weak La Niña for the last couple of months."

She said this week a ridge of high pressure in the atmosphere has been building over the Colorado Rockies and it brought in "quite a bit of warm weather.

"It has been kind of quiet. It has not been a very active period for weather."

She described this particular La Niña season as atypical because of recent snowfall.

"We had a couple of big snow events in December. This is a little out of the ordinary," Stark said.

Colder than average sea surface temperature in the Eastern Pacific Ocean and around the Equator influences location of the jet stream. She said during La Niña, the jet stream is usually driven "pretty far to the north."

Last winter there was a lot of snow in the west and north central United States, and in the mountains of Colorado, Stark said.

"This year it is kind of reversed ... the plains and southeast portion of the state have had more snow than this time last year."

Stark said forecasters are predicting 50-degree weather for the Salida area early this week, and a chance of snow at the end of the week.

"It's hard to say with the timing and strength where the snow will be ... we will have a little better idea as the week develops. The storm could be defined to the mountains rather than lower elevations, but it is something we will have to watch," Stark said.
