A few inches of snow possible in some higher elevationsPosted Apr12, 2008 at 10:06 PM
All of this is being caused by a series of disturbances -- pockets of very cold air aloft -- that will be moving southeastward during the next 48 hours over the Canadian air mass that has moved in at the surface behind the cold front that moved through today. These pockets of very cold air will allow somewhat warmer air with some moisture to be lifted upward and squeezed out, producing showers of rain and snow on Sunday and Monday. As is typical in setups like this throughout the winter, the western slopes of the mountains will be favored for the heaviest precipitation, as the northwest winds guided up the mountain slopes produce extra lift. But even the lower elevations, such as the base of the Roanoke Valley, may see at least some flakes flying through the air by late Sunday night or early Monday. It may seem a little weird to have snow this late in the season, but really, it's not an extremely unusual event. In fact, we had snow showers in mid-April just last year, and the highest elevations in our region sometimes see at least some snow into May. |

John MKevin,
This morning, Sunday, we are experiencing light snow flurries already in the Indian Valley area, close to Indian Valley Elementary School. It started about 9am. Temperature is at 38 degrees and holding steady.
