NWS issues Lane County weather alert for heat, humidity and storms
Lane County was under a special weather statement through 3:15 p.m. as Eugene logged 81 degrees, 42% humidity and a thunderstorm moving north.
National Weather Service Portland issued a special weather statement for Lane County through 3:15 p.m. PDT as hot, humid air and scattered thunderstorms moved across the area. Eugene Airport recorded a thunderstorm earlier, and the activity was pushing northward across the region.
At Eugene, Mahlon Sweet Field, conditions showed 81 degrees, 42% humidity, a southwest wind at 16 mph and a dewpoint of 55 degrees. That mix put the next few hours in the highest-risk window for people working outside, driving between Eugene and nearby communities, or spending time in open areas where a fast-moving storm could force sudden changes of plan.
The weather setup also stood out against the drier backdrop already flagged by National Weather Service Portland. A drought information statement for the office carried a July 14, 2026 update, and the Eugene climate book page says its historical climate data for Eugene was most recently updated in May 2024. In other words, the county went from dry ground to sticky storm chances without much room in between.
Western Oregon has also seen summer thunderstorms turn serious before. NWS Portland’s archived event summaries for the July 1, 2019 Northeast Portland tornado and the October 28, 2018 North Portland tornado show that hail, rotating storms and tornadoes have all shown up in the region when thunderstorm lines organize along the I-5 corridor and beyond. That history does not make every storm severe, but it does underline why a thunderstorm warning over Lane County is not a routine summer note to ignore.
NWS Portland’s ThunderstormsToday page says thunderstorms can affect the Cascades in the afternoon and evening when another system approaches. With the special statement set to end at 3:15 p.m., the most immediate concern centered on the rest of the afternoon, especially for anyone caught between Eugene and the foothills as storms shifted north.
