Following 2 rather wet years in 2018-19 (especially 2019), things took a noticeably-drier turn in 2020, sending nearly our entire 30-county coverage area  into varying degrees of drought during the latter half of the year. Based on ground-truth measurements from dozens of NWS and CoCoRaHS/NeRAIN observers and also radar-estimated analysis, roughly 90% of our area received at least slightly below-normal annual precipitation, and around half of it tallied no more than 75% normal (based on official 30-year normals from NCEI). With little exception, the overall-driest areas (overall and versus normal) focused within several Nebraska counties along and west of the Highway 281 corridor, along with portions of particularly Phillips/Smith counties in north central KS. In contrast, the overall-wettest areas concentrated mainly in far eastern portions of our Nebraska area (especially parts of Thayer/Nuckolls/Fillmore counties) along with much of Mitchell/Osborne/Jewell counties in KS. However, even in the comparably-wetter areas, Thayer and Mitchell were the only two counties in our 30-county area to see predominantly slightly-above normal precipitation.

As evidenced in the list of wettest/driest locations on the graphic, there were actually some fairly dramatic differences in annual totals between locations not all that far apart geographically. One prime example of this involved Hebron (37.22") versus Hastings airport (16.74"), an ASTOUNDING DIFFERENCE of 20.48" between locations barely more than 50 miles apart (as the crow flies)! In fact, versus its 30-year normal, Hastings airport was actually the overall-driest official NWS station in the entire area during 2020, registering its 9th-driest year on record out of 126 and measuring LESS THAN HALF of what fell in 2019 (16.74" vs. 35.20"). 

In summary: 2020 was considerably-drier than the preceding few years, as roughly 90% of our coverage area measured at least slightly below normal precipitation (with various locations mainly near/west of the Highway 281 corridor finishing 5-10" below normal).
