A potent late season snow storm will impact parts of Southern CO and Northern NM over the next 48 hours. This has sparked a winter weather advisory for the Sangre De Cristos, Jemez Mountains, San Juans, and the Upper Rio Grande Valley. Significant snowfall, especially at higher elevations, will be possible this afternoon & tomorrow. In addition to our snow chance, we will also have some very cold temperatures headed our way. Daytime highs will only reach the 50s and 60s today, tomorrow and Wednesday. Today, mostly cloudy and cool with highs near 63°, spot showers possible.
