Snow next week? Maybe!

Well...if everyone is enjoying the wild cold weather, you may be in for a treat next week. After having a nice start to the workweek next week, changes may be in the works for mid-week. A shortwave low looks to develop next week and swing right over our region by Wednesday. This strong low will pull down cold air from the north just as it moves over SW Virginia. Below is the image of the 4-panel MRF view for next week, you can click on it to view the larger image:

Now, taking a look at 850mb temps for this time period. There looks to be a window of about 12 hours that 5,000' temps will be below 0°C. Luckily this area is right over SW VA. The forecasting QPF is showing up to .25" of precip, equating to about 2 or three inches of possible snow, but with ground temperatures still above freezing, it likely won't stay around for long, if it does happen. The 540 line is circle around us, but PU/MO counties are right on the edge of the rain-snow line at the surface. This is still a week away, so things can change, as they have over the past 24 hours with this model. I don't expect too much from this system that swings through, but it would be nice to see some snow showers before Thanksgiving break. I'll keep everyone up to date as the week(end) progresses.
