Weather Forecast
A series of low pressure systems are approaching however models suggest they will be mostly played out by the time they get here. This should bring a few temperature variations however it looks like temperatures will remain below freezing at Little Prairie for the period. Precip amounts will be minimal with mainly cloudy skies and west winds.
Snowpack Summary
Surface hoar formed in open areas on the 10 to 20 cm of snow that fell Dec 13 on a solid rain crust. SW winds began redistributing this on Tuesday likely forming wind slabs treeline and above. Beneath the crust the snowpack is now beginning to refreeze giving it considerable strength treeline and below however basal facets may exist above 2300m
