Tetons

Temperatures are starting out around 10 degrees warmer than yesterday morning. Skies were clear overnight, which enhanced radiational cooling, and wet snow surfaces were able to freeze. Abundant sunshine and very warm temperatures will bring back the chance for wet loose sluffs and wet slabs as the day progresses. The likelihood of cornice failures will also increase with daytime warming. Skiers and riders might still be able to trigger a shallow pocket of dry slab in mostly shaded, high elevation terrain where the winter snowpack is in the early stages of transitioning to a spring snowpack. Get an early start, monitor the sun’s effect on the snowpack and seek out cooler terrain once frozen surfaces breakdown.

Expect light showers to develop after midnight as southwesterly flow brings a weak Pacific disturbance to the region. Initially, the rain line will be around 10,000 feet before an associated cold front moves through bringing it down to 7,500 feet by morning. By Sunday evening, three to six inches of new snow could accumulate in the mountains. Up there, temperatures will be in the upper 20s by daybreak before climbing a few degrees during the day. Overnight lows in the valleys will be near 40 before climbing to around 50 in the afternoon. Southwesterly to westerly ridgetop winds will range from 15 to 25 miles per hour.The general avalanche hazard is expected to be LOW on Sunday. At the lower elevations, warming temperatures and rain will keep the threat of shallow wet slides possible.
