Wider weather episode

Strong moisture advection combined with crossing low pressure to produce precipitation on January 1st. Subfreezing temperatures during the morning were slow to warm during the day, creating a period of freezing rain across the region. This freezing rain lasted the longest along east-facing slopes east of Pittsburgh, where upslope flow ahead of the advancing low allowed subfreezing temperatures to linger longer.
