Weather For Mount Joy, PA On Monday, December 29, 2025

Summary

This morning when I woke up it was much warmer than yesterday. The temperature was in the lower 40s. There was a fairly dense fog. My rain collector had those wacky measurements which I am sure were from the ice again. Dawn brought some fog and cloudy skies with the temperature remaining in the lower 40s. It was in the middle 50s by lunchtime but still cloudy. The clouds did look like they were drying out a bit though. Just after lunchtime the sun came out and wind started. By early mid afternoon it was mostly sunny with very gusty winds. In spite of the sunny skies the temperature began dropping quickly this afternoon after a high right at 50℉. It was in the lower 30s and windy late this evening.
