FIRST WIDESPREAD ACCUMULATING SNOW LIKELY -

This winter has gotten off to an extremely slow start but things are beginning to get exciting. While many are talking about the potential major winter storm next weekend, there is still much to be worked out with that.

A clipper system will dive down from Alberta bringing light snow to the entire state. Alberta Clippers are nearly always “cold air storms,” so we don’t expect any mixing issues in Pennsylvania.

Light snow will move into the state west-to-east. By noontime Tuesday, snow will likely begin to fall across Western Pennsylvania. By late afternoon, snow will move into Central PA and by evening we expect light snow to be falling in Eastern PA.

This will be powdery snow, and as a result it will accumulate fast. By Wednesday Morning we anticipate snow to be over across all areas of Pennsylvania with the exception of the Alleghenies. We predict Western PA will do best with this storm because they are west of the mountains. Here is our forecast map with the key below it.

AREA A – This is where we expect the best snow to fall. Light to moderate snow is likely from Tuesday Afternoon to Early Wednesday Morning. Total snow accumulation of 2-4″ is expected in this region.

AREA B – Light snow is likely from Tuesday Afternoon to Early Wednesday Morning. A short period of moderate snow is possible along a cold front as it sweeps through Tuesday Evening. Total snow accumulation of <1-2″ is expected in this region.

SNOW IS EXPECTED TO ACCUMULATE ON PAVED SURFACES ESPECIALLY TUESDAY EVENING AND EARLY WEDNESDAY MORNING.

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!
