Weather Forecast

Glorious diurnal swings in temperatures making it positively spring like in the mountains this weekend. For Sunday, freezing levels cresting to 2100m with sun and little wind. More of the same leading into the week with strong solar effect and continued, rising freezing levels up to 3000m by mid week.

Snowpack Summary

Melt freeze, spring-like cycle beginning in ernest TL and below. Moist surface snow on steep, solar aspects. Less so in the Alpine where freezing levels (up to 2100m) and cooling winds are keeping the surface dry. Facetting has weakened the upr. snowpack in isolated, shaded areas through the forecast region. Wind effect in open areas in ALP and TL.
