Memorial Day weekend normally signifies the unofficial start of summer. So, it only makes sense that a frost advisory and freeze warning will be in effect tonight.
Despite earlier summertime weather, a frost advisory will go into effect for Pittsburgh Saturday.
A Frost Advisory has been issued for parts of the area for the early Monday morning hours.
Reed Soergel of Soergel’s Orchard and Family Farm in Wexford estimates only about 30 percent of the apples in his orchard survived the snap.
The unusually warm spring has forced trees and perennials into full bloom, so the predicted cold snap with temps dipping below freezing could be a disaster for new growth.
