Weather For Mount Joy, PA On Friday, December 19, 2025

Summary

This morning when I woke up it was much warmer than it has been in a while. The temperature was in the middle 50s. The wind was gusty from the south with rising temperatures. Dawn brought cloudy skies with some rain and dropping temperatures. It was down to the lower 50s after a high in the upper 50s. We had some rain this morning that my weather station did not measure. It was down to the middle 40s by mid morning. The skies cleared late this morning and the temperature rose back to the lower 50s before clouds reformed. A squall line moved through shortly after lunch with very strong winds. I think my weather station measured too high but I think 60+ mph would be accurate. The temperature dropped like a rock after that. We had snow flurries this evening!
