We had an ice day today, with overcast skies, but managed to record some snow melt in the gauge - the sun has enough energy to heat up certain surfaces resulting in snow melt, even with cloudy skies and subzero temperatures, but nothing significant, and no melt on the garden, just on the roof. If tomorrow has sunny spells like forecast then it will really damage our snow cover. The good thing is, we may have drifts until April even here at low elevation, and probably until May for very high routes - that would be great.
