Looks like classic May weather is here for a few days. Lots of showers with occasional steady rain periods. But sunbreaks too. Unlikely that we’ll see more than a 6 hour dry period, except maybe some nighttime periods.
Pattern changes very little in the next 6 days. A cold trough remains offshore the next 3 days and then the entire thing moves inland Friday-Sunday. That means a cooler airmass late week (better chance for cold thunderstorms), leading to Cascade snow down to at least 5,000′. Cold (and crowded) camping ahead for the Memorial Day Weekend.
Beyond that, models seem to be a bit more reasonable for late May, with warming temps back to at least normal and not much rain after Sunday…Mark
