This is the 4,500th IEM Daily Feature! This near daily message started 17 years ago (yikes) as an attempt to entice folks to visit the website daily. I try to highlight an interesting plot or map each day relevant to the ongoing weather with some climatological context provided. I also want to provide reproducible plots with direct links to the website tool that generates the image. Some days are more relevant than others and thus you the reader are given the freedom to vote "Bad" if you don't like what you see or "Abstain" if you can't bring yourself to a binary decision. The featured chart today shows two metrics relevant to the daily feature. The top panel is the time of day the feature was posted and the bottom plot is the percentage of votes in the good category each day. Voting was not implemented until ~2005 and the blip downwards during 2014-2016 was due to a website quirk that was likely registering false votes. Anyway, thanks for your readership and here's to another 4,500 daily features to come!
