EUGENE, Ore. -- It's a smoggy start to the morning.
Some sun will try to sneak through the clouds and smoke this afternoon which will warm us up. This warming will create an unstable environment, which will set the stage for storms this evening as a trough of low pressure moves onshore.
The intensity of the storms will depend on whether or not we get ample sunshine. If the smoke remains stubborn, then the lower atmosphere will remain stable, thus limiting the chances of storms. However, as a westerly flow returns this afternoon, we should see some decent thinning of the smoke.
Storms will fire up between 5 and 8 p.m. and last for a few hours, ending prior to midnight. Off and on showers will continue Friday, but they'll be non-severe.
The biggest threats tonight will be small hail, damaging winds, and potential flooding. In fact, the dry vegetation won't absorb rainfall very quickly, therefore, any heavy rain will run off which could cause issues. For that reason, Flash Flood Warnings have been issued for parts of Linn, Lane, and Douglas counties this evening.
