As promised, here’s your updated outlook for potential thunderstorms along with the forecast for the rest of the week.

Confident:  Strong thunderstorms and heavy showers will develop during the day Wednesday through the evening somewhere north of Eugene all the way up through the Portland area.

Not so sure: Where these storms go no one can know for sure.

My best guess:   The Portland area and points north face the best chance for storms tomorrow.  Salem & Corvallis could see storms, but is currently looking less likely for everyone south of about Wilsonville.  The only exception would be the eastern Willamette Valley such as Silverton & Canby.  I believe that in general the closer you are to the Cascades the better shot you have at seeing a thunderstorm.

Final thought:  Storms could start as early as just after lunch time, so keep a close eye to the sky while you are out and about tomorrow 😉
