Saturday will start mostly sunny as a weak ridge of high pressure moves across the State. Temperatures will quickly warm into the mid to high thirties. Cloud cover will increase throughout the day on Saturday ahead of a low-pressure trough, which is currently pushing onshore from the Pacific. Expect light snow showers to begin over western Colorado by late afternoon. Scattered afternoon thunderstorms are possible as well.
The trough axis moves across Colorado late Saturday night. Snow will increase as the trough passes; however, this is a relatively weak, fast moving, system with little upper level support, so snowfall numbers should remain on the low side. Moisture lingers into Sunday morning, so expect a few orographic snow showers to persist over the mountains into the late morning hours on Sunday. Snow showers will diminish by midday on Sunday as another high-pressure ridge builds into Colorado ushering in another period of dry air, clear skies, and warm temperatures through Monday.
