The European forecast model that came out was the last piece of information that I was waiting for. Sorry for not posting my updates earlier, I was sitting in rush hour. Models now agree on track (they moved slightly north today) with some slight differences in timing, speed and temperature profile. What the models do agree on is that a period of very heavy snow will fall Thursday morning between 4AM and 7AM across the immediate Washington Metro Area.
The image above is from the latest and greatest European Forecast Model (that is circulating on social media this morning) showing the potential for very heavy snow to fall during the pre-dawn hours on Thursday.
