This is a graphic prepared by AccuWeather for predictions of snow accumulation on Saturday.
There’s a lot of discussion going on in the background today about a possible developing winter storm for the weekend here in Central Virginia. As I mentioned in today’s forecast, the potential exists for snow this weekend.
Forecasters in the NWS office in Sterling made this mention in their morning weather discussion:
Guidance now in very good agreement in developing a potentially sig
winter storm during the second half of the weekend in response to
deepening trough over the middle of the country Friday. However…guidance
remains somewhat split with gefs/NCEP means indicating a more of a
southern track (snow)from the southeast coast to cape hatteas and out to
sea while European model (ecmwf) is more robust and much slower indicating a 500 mb
closed low and a track further inland suggesting the possibility of
more of a mixed precipitation/rain event.
As I always say, if you are predicting more than 12-24 hours don’t depend on it, but this does at least raise my eyebrows and much of the data I see right now supports it. I’ll have more in the Wednesday weathercast out at 12:01 AM Wednesday. This event could last into Sunday as well.
