There have not been many posts with a title such as this one during the current winter season. Quite frankly, because there haven’t been many storm threats worth discussing. Rule number one is learn form the past, the past has taught us not stay grounded and be patient when the forecast models show a storm in the long range. We consider anything beyond 4 days to be the long range, weather forecasting becomes increasing fickle in the 5-7 day range. It becomes increasingly difficult for a forecaster in a storm-less winter to not pounce on every storm signal they see like a lion stalking a gazelle.
After much discussion between myself and Bill, we have decided that this once is worth stalking a bit more, not pouncing quite yet. Reason why we are stalking this storm is quite simple, model agreement/consistency, and the fact that by tonight or tomorrow the rumors will be flying anyway. As of this morning we have all major forecast models in alliance on the fact that a low pressure system will be along the East coast by the end of next week into the weekend. All models agree on the timing and all models agree on a significant snowfall in the Northeast. The reason we need to remain grounded is the detail of the strength and the exact track.
The biggest detail that will impact both the track and strength is the interaction between two pieces of energy, something we call a phase. If these two peices of energy phase to late we end of with a storm system that tracks further east, does not deepen to its full potential, is much more progressive with its track and focuses its precipitation to our South and East. On the other hand, if these two pieces of energy phase early we have a rapidly deepening Nor Easter with a track closer to the coast, much slower and the axis of heaviest snow pushes N and W and puts our region in the bullseye. The earlier phase is a snow lovers dream, this scenario puts storm going through rapid cyclogenesis, basically attacking a strong cold high pressure to the north, the result would be strong winds and snowfall amounts of 1-2 feet. The later phase is a decent storm, dropping a swath of respectable snowfall along the i95 corridor with our region in the 1-8 inches scenario.
As you can see, both potential outcomes have vast difference on the evolution of this storm, and with 5 1/2 days between us and this storm it will be important to stay grounded as we track its development. The ingredients that need to come together are not even on the playing field at this point, therefore the models still have a lot of data missing that is needed to come to the right conclusion. In closing, yes there is a storm brewing, yes it is one of the best shots we have had for a winter storm, yes it could be a major storm, but there are a lot of unanswered questions, this is update number one, there will be another update later tonight, and a daily update on this storm threat everyday going forward till it arrives or no longer exists. Everyone have a great day!
