Conditions are starting out dry on Monday morning with mostly cloudy skies, but a system approaching from the west will result in rain showers developing by early afternoon and continuing into the evening hours. A thunderstorm will be possible on Monday afternoon as well. Highs on Monday will reach the mid 50s in the valley and the rain/snow line will be rather high, ranging from 9,000-10,000 ft. on Monday afternoon.
Winds will also become strong out of the west/southwest on Monday afternoons across all elevations. On Monday evening, a cold front will arrive with scattered showers persisting well into the night and snow levels eventually falling to 7,000-8,000 ft., though some flakes couldn’t be ruled out on the valley floor if any shower activity lingers into early Tuesday morning. Any snow accumulations at the higher elevations on Monday night will be light.
Tuesday is looking nice and sunny with highs warming up into the low 60s, though winds will pick up again during the afternoon out of the west/southwest. A big warm-up will occur on Wednesday as a strong ridge of high pressure builds over the Rockies. As a result, we’ll see mostly sunny skies and highs reaching the upper 60s to possibly 70 in the valley. The mid-week warmth will accelerate snowmelt and lead to an uptick in wet avalanche potential in the mountains.
On Thursday, the next system will arrive bringing a good chance of rain showers throughout the day with rain falling even at the higher elevations due to warm air in place. On Friday and Saturday, we will dry out more with only a slight chance of showers both days.
