Yesterday was supposed to be a record snow day in the Northeast. It didn’t quite turn out that way. There was snow — lots of it north and west of New York City. But, the urban centers got only eight to 10 inches. The snow was wet cement and it froze overnight, so one walking on it this morning didn’t sink in. The panic was caused by weather forecasters trying to figure out the collision of two low pressure systems from Washington DC through Massachusetts. Weather models couldn’t predict where the Nor’easter’s center would be and that would dictate the amount of snow cities would get. So, they sounded an alarm days in advance and governors and mayors of the affected states shut transportation down and readied their plows. The blizzard wasn’t a bust, but it also wasn’t the end of the world. The forecasters did their job as well as they could and publicized the potential danger. As a result, tens of thousands stayed home and off the streets. It was good they did.
