Sunday, May 9th, 4:15 A.M.
It’s a cloudy start to our Sunday across northwest Oregon and southwest Washington. A dying cold front will keep clouds around throughout the morning, and a sprinkle or two can’t be ruled out. Based off of computer model guidance, the best chance to see a light shower will be along the coast, the Coast Range and the west side of the Willamette Valley. Most areas should stay dry inland today. Between the afternoon and evening, the clouds will gradually clear out to a mostly sunny sky. High temperatures will be a few degrees warmer than Saturday, topping out somewhere between 64-68 degrees.
This upcoming week still looks warm and dry. If you were to glance at our forecast on paper, it looks more like a July forecast than mid May. High pressure will build in from the eastern Pacific starting Monday, bringing highs to about 70 degrees under abundant sunshine. We’ll climb well into the 70s Tuesday, likely finishing the afternoon around 75 degrees or so. The warmest days of the week should be Wednesday, Thursday and Friday with highs in the upper 70s and low 80s.
Sometime between Friday and Saturday, our models are hinting at the ridge breaking down and low pressure shifting in from the north. At the very least, we should see more cloud cover and slightly cooler temperatures. However, significant rain still doesn’t look likely for the next 7-10 days. Long-range guidance does suggest that a pattern change could occur during the back half of the month. This still doesn’t seem like a lock though.
Time to start watering the garden. Warm weather this week will leave our region even more parched than previous weeks.
