Tetons

Mountain temperatures are starting out near 30 degrees, and inverted conditions strengthened overnight with the valleys around 20 degrees cooler than the mountains. Above 9,000 feet, skiers and riders might be able to trigger a small, isolated pocket of slab in very steep, avalanche prone terrain with dry, wind drifted snow. Small wet loose sloughs could become possible in the afternoon on very steep slopes heavily impacted by the sun. The main hazard is still the lack of snow and the objects residing just below the surface. As high pressure continues, take a mental note where sun crusts and faceted layers have formed near the surface of the snowpack.

Mostly clear skies are in store for tonight and through the day on Monday as high pressure continues to dominate the weather pattern. Temperature inversions will rebuild overnight with the valleys dipping into the negative single digits. Overnight lows in the mountains will be in the mid-teens before climbing back into the mid-30s in the afternoon. Northerly to northwesterly ridgetop winds will range from 5 to 15 miles per hour.The snowpack is mostly stable, and the general avalanche hazard will remain Low on Monday. In terrain above 9,000 feet where snow surfaces have remained dry, skiers and riders might be able to trigger a small, isolated pocket of slab on very steep, avalanche prone slopes. The early season snowpack is becoming more noticeable on aspects significantly impacted by the sun.
