PHILADELPHIA WINTER OUTLOOK 2018-2019
The Winter of 2018-19 is trending to a weak to moderate El Nino and that means one of great potential for snow for Southeast PA, South NJ and Northern Delaware. We took a look at the 67 winters since they began tracking El Nino in 1950. 25 were El Nino years, 21 were La Nina and 21 were classified as neutral winters, meaning no El Nino or La nina.
Of those 25 El Nino winters here is the brekadown of what those El Nino's were like. A weak El Nino tends to occur the most since it is the closest to the normal sea surface temperatures and that's where we see this going this winter with a chance at also a moderate El Nino.
So we threw out the years before 1977 and took a look at the most likely winter for the Delaware Valley based off past weak and moderate El Nino's the past 67 winters. Here are the analog years or simply put...the years that match up most likely for the winter ahead (2018-19).
