These images depict September 2018 monthly temperature departure from normal & precipitation percent-of-normal for both Nebraska & Kansas. Images are courtesy of the High Plains Regional Climate Center (HPRCC). Please note: These maps occasionally contain "bullseyes" of errant data. For precipitation, you can also generate departure from normal/percent-of-normal maps using the NWS AHPS page, or view local-area images generated each day by NWS Hastings.

Drought:

Summary of changes during September across the NWS Hastings coverage area:
Given that September rainfall was solidly above-normal within the handful of southeastern local counties that had previously featured Abnormally Dry (category D0) conditions throughout late July and August, this area of D0 went away completely from the ENTIRE NWS Hastings coverage area during the month! In other words, the entire local area was considered "drought-free" heading into October.
