A weak disturbance approaching from the south will result in mostly cloudy skies through most of the day on Tuesday along with some isolated showers and thunderstorms. However, moisture in the atmosphere is lacking so any rain will be brief and light.

Highs will reach the upper 70s on Tuesday afternoon with some clearing possible by late in the day. Breezy south/southwest winds can also be expected with gusts to 35 mph in the afternoon before decreasing in the evening.

Wednesday will be mostly sunny and dry with highs warming up into the low 80s. Winds will become breezy out of the south during the afternoon and will continue through Wednesday night with gusts to 30 mph.

On Thursday, a stronger disturbance will approach from the southwest and a cold front will arrive around midday. Highs in the low 60s will occur early in the day, before falling into the 50s in the afternoon with gusty west/southwest winds also expected.

Showers will develop behind the front during the afternoon and will be fairly widespread with wetting rains expected, though total rain amounts will not be particularly impressive. Showers will linger into Thursday evening before drying out overnight.

Temperatures will also be cold enough for light snow to fall across the higher elevations behind the cold front. Snow levels will start out around 10,000 feet before falling to 8,500 feet by mid-afternoon, and then as low as 7,500 feet by Thursday evening as precipitation tapers off.

Friday morning will start out chilly with temperatures likely dipping down to freezing in the valley, though it will depend somewhat on how quickly the cloud cover clears. Sunny skies will allow temperatures to rebound nicely in the upper 60s to near 70 by Friday afternoon, resulting in a beautiful day.

A significant warm-up will occur over the weekend as a ridge of high pressure builds over the Rockies, resulting in a return to above-average warmth. Highs will reach the low 80s on Saturday, but then will soar into the upper 80s on Sunday and into early next week, which is approaching record levels for this time of year.
