The following is provided by DC Severe Winter Weather:

Right now we are currently observing the potential for some wintry weather Wednesday night into Thursday morning. Although there are a lot of uncertainties with this storm we do believe that it will bring some sort of precipitation to the area.

The European model right now is showing 3-5 inches across the DC metro area, and although this snow will be wet and have a hard time sticking to roads due to the warm air earlier this week, we do believe that if this scenario were to play out, that we would finally have some delays and possibly even closures Thursday.

The other scenario is being shown by the North American Mesoscale (NAM). It predicts that there will not be enough cold air ejected to the storm to cause a significant impact on the area, and will have a hard time switching over to snow.

We currently slightly favor the European model at this time due to the Southern trend, although there is the potential for anything at the moment. We will have a more definite call tomorrow as the models will start to converge on a single scenario, and we will be able to produce a snow map.
