Saturday Update on the Coming Week...

We remain on schedule to see the arrival of Arctic air later this week, and certainly the coldest of the season. The question remains will we see any snow? There will be a series of disturbances travelling across the Mid-Atlantic through a developing upper level trough in the eastern U.S. Each one may bring a threat for precipitation. The leading edge of the Arctic air will be following a system that comes over us on Tuesday. This may trigger scattered rain and snow showers. Behind it, temperatures on Wednesday will probably struggle to get out of the 30s. The most intriguing situation to me remains late Wednesday night and Thursday, as the next disturbance comes through the trough. I have posted the European model charts for Thursday morning below. The upper left shows the upper level flow, and we can clearly see the trough digging south and east. The top right shows the surface features and the area of low pressure is tracking over northern Virginia. The bottom charts show moisture and all the models agree at this point with keeping most of the moisture north of us. This means there won't be much to work with, but don't be surprised if we can squeeze out something. This won't be a major storm, but I'm still suspicious we'll see some of the white stuff flying in the air on Thursday (at least snow flurries/snow showers). The bitter cold will follow on Friday into the next weekend. Stay tuned for updates...
