The October 2020 ice storm snapped many tree branches across the National Weather Center’s grounds, certainly including unaccustomed nonnatives like these Chinese pistachios. The early-season (fall) ice storm wasn’t large in magnitude, with accumulations generally around 1/4 to 1/3 inch here. However, because it happened while so many leaves still were green, or just starting to change color, and firmly attached to trees, that magnified the impact because of total ice load on trees similar to far greater accumulations in wintertime (about 3/4 to 1 inch).
