Folks in eastern Northampton County of PA and western Warren County of NJ will wake up Saturday morning to a cold rain. A changeover to snow is expected by early to mid afternoon, and a heavy, wet snow should continue through Saturday evening. A general 6" snowfall is anticipated, with more likely in higher elevation areas, and a bit less is some of the valleys. Generally, roads will turn slushy by evening, and some, especially less traveled ones, will see accumulating snow.
Our biggest concern from this storm will be an accumulation of snow on tree branches. With many leaves remaining on trees, the weight of the snow will cause branches to break, leading to road closures and power outages.
October snowstorms are rare, so expect some twists and turns to the forecast during Saturday and Saturday evening.
By Sunday, conditions will turn more seasonable, and trick-or-treaters should have no problems Monday night!
