The National Weather Service has issued a Winter Storm Watch for much of the Washington, D.C. area Thursday and Thursday night for the potential for more than 5 inches of snow.
Our opinion is that this is premature and overdone, and that current available information does not support this forecast. 5 or more inches of snow is not impossible from this event, but is very unlikely - less than a 10 percent possibility. We would not have issued this watch - although we do think there is a possibility of accumulating snow - 1 to 3 inches perhaps being most likely. We would only give a 10 percent chance of 5 inches or more snow from this system.
We will have more details shortly.
