Snowfall Expected in Central Wasatch by Early November
• The central Wasatch region is anticipating a shift in weather conditions as an upper-level trough approaches, bringing the potential for snowfall. Current forecasts suggest warm and windy conditions through Halloween, with temperatures near +1°C (33.8°F) at 10,000 feet. Snowfall is expected to increase starting Sunday, with the European Ensemble (ENS) predicting up to 20 inches of snow at Alta Collins by 0000 UTC on November
• However, the GFS model is less optimistic, forecasting around 13 inches of snow. The timing of the cold front and the transition to colder air remains uncertain, which could influence precipitation type and snow-to-liquid ratios.
Impact & Risks
The snowfall will primarily affect higher elevations above 10,000 feet, such as Alta Collins, where snow cover is already limited. Warm conditions through Halloween may lead to further snow loss in sun-exposed areas. The variability in model predictions introduces uncertainty in snow accumulation and precipitation type, with some scenarios suggesting rain at higher elevations. Skiers and outdoor enthusiasts should prepare for potentially wet or dry snow depending on how quickly temperatures drop.
