Winter Storm Bumblebee Tuna (Dec. 14-15)

Posted on

Event Start: Between 3AM and 6AM on Saturday

Event End:  Main precipitation moves out Sunday morning. Lake-effect continues into Monday near Great Lakes

Forecast For Various Western/Central PA Cities:

  • Erie: 6-10″
  • Edinboro: 4-8″
  • Oil City: 3-6″
  • Butler: 3-6″
  • Pittsburgh: Dahntahn 1-3″; ‘Burbs 2-4″
  • Uniontown: 1-2″
  • State College: 3-6″

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.
