Snowfall Monday?

Snow across the northern mountains today becoming lighter overnight. The heaviest rates are expected from now through 5pm. Travel may be impacted along U.S. 64, NM-17, NM-38, and NM-518. A Winter Weather Advisory is in effect for the Tusas and Sangre de Cristo Mountains through 11 AM Sunday.

A storm system will bring light rain and high mountain snow to the region today into tonight. Heaviest qpf (snow) amounts will be above 8,500 feet in the Tusas Mountains east of Chama and in the Sangre de Cristo Mountains. Slick mountain passes (i.e. U.S. 64, NM-17, NM-38, and NM-518) may develop due to the snowfall. Rainfall amounts generally below 0.25 inches across lower elevations of western and central NM.

Windy conditions will prevail across east central and northeast NM on Saturday. Strong crosswinds may impact I-25 from Raton to Las Vegas, U.S. 285 between Clines Corners and Vaughn and other north to south oriented roads.

A potent cold front will blast through NM Sunday resulting in the the coldest temperatures since December 5th. Wind chills will be even colder. This cold air will be a big shock after the recent record warmth these past 2 to 3 weeks. These readings are only about 5 degrees below normal.

Lingering moisture along with much colder air behind a front will result in the potential for a band of snow to develop across south central and southeast NM Monday morning. Potential exists for light to moderate snowfall accumulations across south central and southwest Chaves County and southern Lincoln County on Monday. Forecast confidence for this snow is low at this time, so people planning on travelling across this area on Monday should stay tuned to the latest forecasts.
