Severe Weather Summary:
Following at least 2.5 weeks of bone-dry weather across all of South Central Nebraska and North Central Kansas, an expansive, slow-moving upper level low pressure system took aim on the Central Plains during a 3-day period centered from Friday, Oct. 7 to Sunday, Oct. 9, 2011. While locally heavy rain over the course of several days ended up being the main story across mainly western sections of the area (see Heavy Rainfall section below), there was one distinct episode of strong to severe thunderstorms that targeted mainly a narrow corridor across northern and western sections of South Central Nebraska on Friday the 7th into the post-midnight hours on Saturday the 8th. These storms resulted in several reports of damaging wind gusts and hail to the size of quarters. Although a few storms exhibited some rotation, no tornadoes occurred. Given that this activity took place on a fall Friday night, several area high school football games were affected.
Here are a few "highlights" of the severe weather event, based on PRELIMINARY reports from storm spotters, local law enforcement, emergency management, and the public:
Locally Heavy Rainfall and High Multi-Day Totals:
As described above in the severe weather section, the most significant impact from this slow-moving low pressure system ended up being hefty, multiple-day rainfall totals into the 2-7 inch range across much of the northwest half of South Central Nebraska, along with parts of mainly Phillips County in North Central Kansas. Even south and east of the primary zone of rain, many locations picked up at least 0.50 to 1 inch of rain. However, far southeast portions of the NWS Hastings coverage area really missed out, with places such as Hebron and Superior only mustering around
Despite putting a temporary halt to the fall harvest, this was much-needed rainfall, as the entire area had gone at least 2.5 weeks with NO rain, and the preceding month of September had featured well-below average rainfall. Fortunately, due to the dry conditions leading up to this event, widespread flooding impacts were held to a minimum.

Corresponding to the tables above, featured below are a series of GIS maps reflecting rainfall totals from this event. The top row of three maps reflects 24-hour rainfall totals ending around 7 AM on on Oct. 8th, 9th, and 10th, capturing the majority of multi-day rainfall amounts. These maps focus solely on the NWS Hastings 30-County Warning Area, with reports courtesy of NWS Cooperative Observers, Nebraska Rainfall Assessment and Information Network (NeRAIN) observers, CoCoRaHS observers and automated airport sites.
