Spring is here, the bugs are coming back and short sleeves are breaking out. But just wait, because Winter plans to make a return. A trough will bring cold air back to the region by Saturday Night and by the time Sunday rolls around we will likely have a strong low pressure system off the coast. The big question is how far off the coast? This is the million dollar question that will determine everything.
Some models keep the storm just too far off of the coast to keep our impacts minimal while others indicate the storm will be slightly closer to the coast. With a -NAO and a -AO, this would be the ideal time for a first day of spring winter storm.
From here on out this will be a game of trends, even a 100 or 200 mile shift west will be the difference between a minor storm and a major winter storm. Even with a storm track staying well off the coast, Sunday will be very cold and snow showers will be likely in parts of PA.
This will greatly depend on timing, at this point in the year only a major winter storm will result in snow sticking to roads. Stay tuned!
