First Cold Shot of Winter to Arrive Late This Week -

The past several weeks have brought nothing but abundant warmth. Temperatures have reached the 60s and even low 70s across much of PA both Saturday and Sunday. But we knew that at some point winter had to show up.

A deep trough will move into the Eastern US late this week and by Saturday highs in the 30s will be present throughout the entire state. This will continue into Sunday, through next Monday.

Lake effect snow bands will likely setup in Northwestern Pennsylvania next weekend as heavy westerly winds blow over Lake Erie. At this time we do not expect significant snow accumulations but light to moderate snowfall is definitely not out of the question. Stay tuned!

Lead Forecaster Josh Adams

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!
