Weather For Mount Joy, PA On Friday, July 21, 2023

Summary

It was very warm and humid before the storms approached last very early in the morning. The temperature and dew point had been holding steady in the mid 70s. There were some nice strong winds ahead of the line of storms which my weather station grossly underestimated and then the normal rain and thunder and lightning with the storm. That brought the temperature down to a much nicer mid 60s. There was periods with a good bit of sunshine today. The high was in the middle 80s with it being less humid.
