Weather For Mount Joy, PA On Tuesday, December 16, 2025

Summary

This morning when I woke up it was colder than yesterday. The temperature was in the lower teens. Shortly after I got up the temperature dropped into the middle single digits. Dawn brought clear skies and a low just below 5℉. That low was not uploaded because our internet was down. That fresh snow and fairly calm winds last night really helped the temperature drop! Late this morning it was into the middle 20s with bright sunshine. The high today was just above freezing.
