If you thought July was unusually cool, you were right. In fact, when you combine June and July, it turned out to be the coolest two month period since 2004, and one of the coolest on record. A persistent upper level wind pattern kept south central Nebraska and north central Kansas on the edge of the heat to the southwest, and able to share in some unseasonably cool air positioned around the Great Lakes and eastern Canada. The pattern resulted in several cool mornings, many pleasant evenings and some not-so-hot afternoons.

The Tri-Cities of Grand Island, Hastings and Kearney provide a reasonable dataset for examining climate records in the area. Grand Island's data goes back to October 1895, and is considered the most complete and climatologically reliable. The Hastings data dates back to 1907 for temperatures, while Kearney goes back to 1901 for temperatures.  Climatological data for Grand Island and Hastings are collected by an Automated Surface Observing System at the airport at each city. Climatological data for Kearney is also from the airport area, but is collected daily by a NWS Cooperative Observer.
