After a week of warmer temperatures and many areas of Pennsylvania reaching 60 to even 70 degrees, it’s understandable that cold air won’t be in place for this storm in 90% of the state. However, the coldest region of the state – the northern mountains, will be seeing snowfall on Sunday.

This storm is so thread the needle in Northern PA, and most towns are in valleys which further complicates things. Elevation and latitude will play a huge role in this event. Mountaintops will receive noticeably more snowfall than surrounding valleys. Also, temperatures will be above freezing as the snow falls in the valleys, but we expect snowfall rates to cause roadway accumulations regardless.

Josh has been passionate about weather as long as his memory dates! From watching the Weather Channel at age 7, to making hand-drawn hurricane maps at age 11, starting his first weather site at 13, and founding PWA at 15 and forecasting for the state for the past 9 years, Josh's interest in weather has never dwindled! As difficult as it is, he greatly enjoys forecasting for Pennsylvania due to its countless microclimates. The state is an East Coast severe weather hotspot and nearly always home to the rain/snow line during winter storms!
