*NOTE: This data is only for the highest dewpoint recorded on a given day and does not take into account the lowest or average dewpoint for the whole day. The highest dewpoint is a good measure of the moisture content of the air. In the cool season, there is also an enhanced potential at severe weather occurring if the dewpoint reaches into the upper threshold (generally 95th percentile and above) for a given month.
