4 Days Out: Sandy Could Be Historic, Ohio Snow?

With each model run, Hurricane Sandy looks to be headed toward the mid-Atlantic, with a probable Monday afternoon landfall. The NHC won't commit to that track, but the Euro model has been the most consistant and has been bringing it to the mid-Atlantic for the past couple days.

What makes this storm potentially historic is the way it will combine with a strong trough moving across the country right now. In a scenario not too different from "The Perfect Storm," the rare combination of an arctic system and a tropical system will create a super-storm over New England and the mid-Atlantic.

How this thing develops is amazing, considering the sheer magnitude of this.

Sunday the Euro model shows Sandy approaching the coast as our trough begins to stall over the Appalacians, leaving us in a cold pool this weekend. Our weekend cold front becomes the last piece of this huge puzzle:

By Monday afternoon Sandy makes landfall and combines with the energy from the cold front to become an absolutely massive storm system. Sandy's peak winds will diminish, but the overall Tropical Storm and Hurricane force gales could reach over 300 miles from the center, making this more than a landfall event. The circulation from Sandy will draw more cold air in to the mid-Atlantic:

Effects on Ohio
This is where the forecast gets interesting, and is still to be determined. IF enough cold air is brought down from Canada, and IF enough moisture makes its way across the Appalacians, we could have one of the earliest snow events in recent memory.

The latest Euro model is the first run to depict snow late Monday night in a band moving east to west across Ohio. With this scenario, accumulation would be light and would change over by daybreak Tuesday to an all rain event:



This is a stretch. So many things have to fall perfectly in place for this to happen. And even if this does happen, it'll be so minor in comparison to what the East Coast will see. However, it's exciting for snow watchers here in Ohio.

I'll write more tomorrow or Sunday, depending on the changing models.
