This paper identifies temporal and spatial patterns in the diurnal cycle of hourly warm season precipitation events over the Great Plains of the US. Results from 30 years of hourly precipitation records from 515 stations indicate that over 60% of all warm season rainfall (more than 0.25 mm) occurs at night from southern Nebraska to panhandle Oklahoma and portions of northern Texas. The larger precipitation events (more than 2.54 mm) display a much larger region where 60% of the warm season precipitation occurs at night. Harmonic analysis reveals a remarkably uniform longitudinal gradient in the timing of maximum rainfall frequencies across much of the Great Plains. The more precise identification of these spatial and temporal patterns should be particularly useful in 1) assessing the many theories of nocturnal precipitation in the central US, 2) verifying numerical precipication models for the region; and 3) generating rainfall forecasts for various times of the day.-Author
