The leading edge of a snow shower moves southeast across Montgomery County Tuesday afternoon. This photo was taken from a 5th floor office building in Tysons Corner, Virginia at 3:07 p.m.

As I drove into the parking lot of my Tysons Corner office building at noon on Tuesday, my car’s thermometer read 28 degrees. I noticed dark clouds gathering on the western horizon so I decided to take my camera into the building. My office is located on the 5th floor and offers a good view of the sky.

Between 1 and 2 p.m, scattered snow showers and snow flurries became visible in the northern sky. They were large cumulus clouds that resembled “pop-up” summertime showers. The base of the clouds were dark small shafts with precipitation falling.

By mid-afternoon, the clouds became much larger and began to resemble small thunderstorms. The snow showers and snow squalls were arranged in well-defined lines that moved northwest to southeast across our area. One snow squall over Montgomery County looked particularly threatening. Its photo is displayed below.

The snow showers moved very quickly, and unlike thunderstorms which have dark rain shafts below the cloud deck, the snow showers had white, wispy shafts of snow that were blown out ahead of the squall. It was an unusual sight for our area.

In Tysons, I never saw the first snow flake fall. Snow showers passed by me in all directions, but not overhead. I followed the radar and snow reports at the Capital Weather Gang and I got a call from home to tell me the ground was coated white near Oakton, Virginia. Despite the lack of snow in Tysons, the view of snow showers and snow squalls was quite amazing.
