General thoughts on the upcoming period from Mount Holly..
For Friday through Sunday...As the aformentioned upper-level trough continues to amplify its way into the East, our sensible weather will first be dominated by arctic high pressure centered across southeastern Canada and New England. A rather cold air mass is forecast to be in place, however incoming upper-level energy looks to initiate a wave along an offshore baroclinic zone. There is typically more uncertainty especially the details and timing this far out, however the overall pattern looks to favor some sort of cyclogenesis near or offshore of the East Coast over the weekend. We continue to maintain some chance PoPs for now in the Friday through Saturday time frame, however some guidance is slower with the storm development and delays it until Sunday.
