After I wrote my column Saturday afternoon — of course — one could see moisture streaming over the top of the massive ridge of high pressure and moving southward over the interior of British Columbia on Sunday. This produced enough moisture in the lower layers of the atmosphere and aided in providing a lift that produced some periods of light snow.
With cold air trapped in the upper few thousand feet and lots of containment air particles, it was perfect for some low-level snowfall. It was sunny at Timberline and warmer in some parts east of the mountains than it was right here in Clark County.
The first few flakes fell early Monday and picked up around noontime. Another band came through around 4 p.m. and whitened the ground again in Salmon Creek, where my high was only 32 degrees.
Given the changeable atmospheric conditions, some areas saw more snow than others. With temperatures at or below freezing Monday afternoon, this morning was expected to be icy, with the left over moisture on the roadways.
