Thursday’s main severe-weather window runs from 2 PM to 2 AM Friday, with forecasters warning some afternoon and evening thunderstorms could turn strong to severe.
An erratic low-pressure system is pulling very warm, moist air north into colder air aloft, creating enough instability for damaging wind gusts, 1-inch hail and a quick spin-up tornado or two.
Friday and Saturday stay windy even after the thunderstorm threat fades, as a cold front pushes the system out and leaves behind pressure-gradient gusts strongest in the Kittitas Valley.
Temperatures add to the volatility: the Tri-Cities are expected near 90 Thursday, around 75 by Saturday, then back near 90 by next Tuesday.
