A Winter Weather Advisory is in effect through Tuesday for the Cascades and east slopes in Central Oregon, with 2-3 inches of snowfall expected daily. A Dense Fog Advisory is also in place for parts of the region this morning. Temperatures will be in the upper 20s to low 30s, with light rain and some snow mixing in this afternoon. Cooler temperatures, with highs in the mid to upper 30s, are expected throughout the week.

Why it matters

The persistent mountain snow and icy road conditions could impact travel and outdoor activities in Central Oregon this week. The dense fog also poses a safety risk for drivers during the morning commute.

The details

A low-pressure system moving in from the Gulf of Alaska is bringing the colder air and moisture to the region over the next several days. While snow accumulation on the High Desert will be limited, areas like La Pine and Sisters could see around an inch of snowfall. Temperatures are expected to drop, with highs only reaching the mid to upper 30s this week.
