Mixed Precipitation Possible This Week...

Colder air will filter back into the region tonight and tomorrow, setting the stage for a rather chilly and unsettled period during the coming week. A boundary setting up shop over the Mid-Atlantic will focus some moisture over us by Tuesday. This will be the result of milder air running up and over the colder air at the surface (known as overrunning). Temperatures at several levels in the atmosphere will be critical to what type of precipitation we receive. Right now, it looks like a mixture of precipitation types over central Virginia...mainly snow and/or rain. Any turn to a colder profile would provide the possibility of some accumulating snow, so we'll have to watch this developing situation rather closely. It appears that eventually the milder air will win out by Wednesday, meaning just rain showers. However, this is a rather dicey situation, so we'll just have to see how it plays out. Either way, it looks rather unsettled through the middle of the week. Stay tuned for updates...
