2017 Precipitation Bins

Posted: 27 Jul 2017 05:51 AM

The Sioux City Airport weather station reported just over 6 tenths of an inch of rain on Wednesday, which was very much needed. The location is still running a significant deficit for the year and the featured chart attempts to illustrate if the location has missed out on the big rainfalls or little rainfalls so far this year. The long term daily precipitation record is partitioned into five bins, with each bin contributing an equal amount of rain volume for the year. The chart shows the average number of days for the year to date period with that amount of precipitation being reported. The percentages express the difference in precipitation totals for this year from this average for the bin. So the plot shows that for the highest three bins, this year has come up short both on the number of days and total amounts. For example, we should have seen about ten days with a total of at least 0.53 inches. This year, only five have happened so far.

Good = 6
Bad = 0
