NWS: 12 to 18 inches of snow to fall locally

Winter storm expected to begin mid-day today

A winter storm is expected to blanket much of the Juniata Valley with 12 to 18 inches of snow this weekend before giving way to bitter cold temperatures and sub-zero wind chills, according to the National Weather Service.

A winter storm warning has been issued for most of central Pennsylvania that is in effect through Sunday morning.

Winter Storm Harper is predicted to arrive by mid-day today with the heaviest snowfall forecast to occur overnight tonight into early Sunday morning. According to NWS models, the precipitation should finish falling no later than early Sunday afternoon.

Most of Mifflin County and a large portion of Juniata County are expected to receive at least a foot of snow. Other areas in those two counties are within the predicted range of 8 to 12 inches.

According to Phil Lucas, the Mifflin County Director of Emergency Services, there is a decreasing estimate of ice/sleet but due to the increasing winds and near zero temperatures, power outages due to falling trees/limbs are to be expected.

Lucas also said when traveling, be prepared for poor conditions during the snow storm followed by blowing and drifting snow.

Once the snow is done falling, the area is expected to be hit with a blast of arctic air, with temperatures overnight Sunday falling near zero. Monday’s high is expected to be in the teens with the low overnight Monday into Tuesday morning dipping below zero. Wind chills Sunday night are expected to be around minus-15 degrees.
