The weather over the past weekend continued the October trend of very mild and humid conditions. The featured chart presents some metrics on October dew point temperatures based on period of record archives from Dubuque. The top panel, which could use some tweaks for readability, presents the percentile values for dew point temperature by hour of the day. The bottom panel is more interesting and shows hourly dew point percentiles for each hourly report so far this month. Observed dew points for the entire month have been 90th and higher percentile range. Such high readings preclude any chance of the first widespread frost as humid conditions buoy temperatures during the night time. Our humid October does look to change later this week with more seasonable temperatures and values approaching the freezing level by next weekend.
