Local Gradients

Posted: 23 Sep 2021 12:06 AM

The most recent rainfall event on Monday evening very much frustrated residents of Ames as higher rainfall totals were had just outside of town in seemingly all directions! The same residents complained that this "missing out" has taken place most every time it rains this year. To test this hypothesis out, the featured map presents total precipitation estimates by the NOAA MRMS project for the year over the Story County (Ames) area. Sure enough, some of the lowest rainfall totals on the map can be found over Ames and Nevada with 5-7 inches higher totals found just a few miles north and south of the area! The meteorological reason behind this gradient remains elusive.

Good = 14
