It was quite a stormy Thursday evening throughout the Treasure Valley and Eastern Oregon!
The National Weather Service reported a record-breaking 68 mph wind gust from the outflow of a nearby thunderstorm at the Boise Airport as of 4:04 p.m. This was the strongest gust ever recorded at the Boise Airport in the month of May. At that same time, a storm east of Burns, OR, was producing radar-estimated 2-3 inch hail, according to NWS Boise.
The storms started to develop just after 3:30 p.m. and were mainly focused just south of the Treasure Valley, tracking southeast to northwest, and brought hundreds of lightning strikes to the Owyhee Mountains along with strong winds, large hail, and heavy rain.
Those severe thunderstorms rolled through the Treasure Valley yesterday afternoon around 4 p.m. and brought wind gusts up to 68 mph, power outages, downed trees, hail, and flying debris to the region. Erin Banks Rusby snapped the photo above of a downed tree in the Sunset neighborhood in north Boise.
Idaho Power’s outage map also showed over 6,000 homes losing power due to the storm system.
Looking ahead, scattered showers and weaker thunderstorms will linger over the West Central Idaho Mountains today and then decrease on Saturday with mostly dry conditions returning next week
