A cutoff low currently located in central California is responsible for the heavy snows located in southern Colorado. Some light snow continues over our area as southwest flow is lifted by a dome of cool air over the valley, but the main action is to our south. There may be an additional 1-4” of snow overnight if the energy from the cutoff low wobbles northward, and maybe another inch or two during the day tomorrow before energy eventually sinks south of our area by Monday night.
Skies should clear for Tuesday as temperatures warm. But the break will be short-lived as a disturbance in northwest flow passes over the area on Wednesday. Additionally, some cool air from the western side of the still vigorous Hudson bay vortex will mix with the storm, with some models dropping the system a bit too far west for the best snowfall for our area. This may change, but current forecasts have snow starting around mid-day Wednesday with 3-6” falling by Thursday morning.
Snow will barely end before another major storm very similar to this past one begins to influence our area as soon as Thursday afternoon. Again, this looks like a long-duration event that may last through next weekend with some snow each day. Stay tuned for more details as the event draws closer.
