The calendar says it is May, but the weather says it is summer! Monday’s high of 86 was 21 degrees above average. Summer? Yes, indeed. It was in the low 80s Sunday. All this is on the heels of the warmest April on record.
Seattle aced out Vancouver by 1 degree with a high of 87. We thought those 85- to 90-degree highs in April were something. Will it last into summer and develop into a sweltering season?
As El Niño vanishes and La Niña is in the wings, I would be hard-pressed to say with certainty. Statistics suggest a warm, dry summer. More thunderstorms will likely mix in after a few hot days. The dog days may arrive early.
The clouds you saw Monday afternoon were trying to induce a few of those thunder boomers over the Cascades, but as of 5 p.m. not much over Clark County. Today through Thursday, we will have cooler temperatures and a risk of showers all three days. Nothing heavy, I don’t think.
