August 13, 2025

Heat, storms, and heavy rain

The week began with seasonally cool temperatures and scattered showers and storms across southwest Nebraska and the Highway 81 corridor, with an area of heavy rainfall in eastern Knox County on Sunday. An observer just south of Bloomfield had over 4" last Sunday and almost 8.50" for the week. Additional showers and storms affected the eastern side of the state on Monday. Total precipitation for last week is shown below in Figure 1.

Temperatures began to warm up early in the week in the Panhandle with highs in the 90's starting on Tuesday as a southwest ridge began to build north. A complex of storms rolled around the ridge late Tuesday night into Wednesday morning bringing widespread 0.50-1.25" of rain to the eastern sixth of the state. Temperatures continued to warm in western Nebraska and peaked on Thursday in the Panhandle with sites around Chadron easily exceeding 104°F for a high temperature.

By Friday a sharp trough (Figure 2) had moved into northeastern Montana and a cold front was working its way through Nebraska at the surface. Elevated storms developed in eastern Colorado and southwest Nebraska on Friday evening just behind the front. Ahead of the front on Friday afternoon, it was a sultry afternoon in central and eastern Nebraska with temperatures in the 90's and dewpoints in the 70's.

The worst damage was in Fillmore, Saline, Seward, Lancaster, and Washington counties. Winds over 90 mph were reported between Geneva and Lincoln and winds over 80 mph also occurred between Valley and Blair. A more thorough report on the event is coming soon. In the meantime, the radar loop of the event is in the related links.
