Main Threats:
- Heavy snowfall is possible at times, especially in southern PA along turnpike and into central PA
- With southerly flow aloft, temperatures aloft could rise to above freezing above the surface allowing for freezing rain/sleet to fall.
- Once the main system pushes through on Sunday, temperatures will decline and any free standing water could refreeze and create black ice.
Main Risks:
- Upper-level southerly flow could bring warm air aloft across the southern tier, bringing rain/sleet/freezing rain into the region and decreasing snowfall totals
- A heavy band of precipitation could set up along the southern tier and into central PA, bringing potential heavy snow and increasing amounts along turnpike and into central PA
- Lake-effect snow lingering through Sunday could add additional snowfall to areas in northwest PA if bands set up for long duration.
