SUMMARY: This was a typical July with the expected heat and humidity and scattered showers and storms. The first third of the month was relatively cool, but the latter two thirds were consistently warm, bringing the mean temperature up slightly above normal. There was a lack of organized, widespread rain events, so nearly all of the rain fell from hit-and- miss showers and storms. Thunder was observed on 10 days, but ironically the three heaviest rain days did not have thunder.
