1. The NAO will go positive this weekend which means the blocking is currently weakening, and that by the weekend, we are into a whole new weather pattern. That pattern will be less stormy in the East and more stormy in the West. It also means the storm coming up is not going to last all that long, but during its stay, it will still cause problems as previously stated.
2. Adjusted the snow area east and put a 30% chance of heavier snow for southeastern Pennsylvania and New Jersey. The concern here is the heavier precip and the fact the storm is bombing out may cause a burst of heavy snow to develop that can give a quick 3-4 inches. The storm will weaken going north so snow area should dwindle down to an inch or two.
3. Wind, rain and coastal flooding predicted have not changed. It still looks bad for coastal areas hit by Sandy.
4. Severe weather threat will unfold this weekend in the midsection of the country as the next storm comes out of the Rockies. More on that Thursday and Friday.
