Water Year, Halfway Point
Posted: 31 Mar 2022 05:27 AM
It seems kind of strange to say it, but we are now about halfway through the "water year" which starts
on 1 October. One of the driest locations in the state over this period is Sioux City, but recent
precipitation events have helped the accumulation total. The featured chart presents the accumulated
precipitation totals to date for the water year with the envelope of observations shown by the tan area
and the NCEI climatology with the dashed black line. This year's total in red shows the recent up-tick
and values now not too far from average. The steepening of the climatology line tells a good story as
well with each day increasing our expectations for rainfall amounts and thus it becomes easier to make
up deficits as daily rainfalls increase as well as quickly increase deficits without rainfall as climatology
zooms higher.
