.DISCUSSION...Light snow is still forecast today, with the bulk of
that falling this morning. Gusty winds will likely producing some
blowing and drifting snow, but it should be anything widespread as
the strongest winds and finer snowfall should be at much higher
elevations. Occasional light snow is possible Tuesday night and
Wednesday, mostly toward Galena Summit and the Stanley Basin.
Winds also increase Wednesday ahead of the next storm. Winds may
indeed be strong enough for some blowing/drifting snow of any snow
that is on the ground at the time. We will remain with occasional
snow (nothing too heavy) heading into the weekend. The focus for
any periods that could bring more snow would be Thursday and
Saturday/Sunday.
