Quick synopsis: For the month of July, mean temperatures were warmer than normal throughout most of the state with the exception of some coastal areas which were near average or slightly cooler than average. Precipitation was nearly non-existent with most of the state receiving less than 5% of the average amounts. It should be noted, however, that the state is usually quite dry this time of year.
