Chief Meteorologist Justin Stapleton‘s Daily Forecast Discussion:
Mild tonight and even with clear skies, temperatures won’t fall that much out of the upper 50s and low 60s. The morning clouds will move back in some spots, but there will be sunshine as well. Lots of interesting weather for the weekend forecast, including a chance for thunderstorms on both Friday and Sunday. Then we really see the heat bake the Pacific Northwest.
High pressure remains the dominant weather pattern for the rest of the week, weekend, and into next week. So, hot weather fans will continue to enjoy days climbing into low 90s and sunny skies. Heading into the weekend, an upper level low will swing in from off the California coast, helping to trigger thunderstorms across the Cascades and because of the hot and unstable nature of the air, we might see some hefty ones. Later that evening, some storms might try and slide on into the valleys. There’s a chance we won’t see any if storms fire earlier in the day in the Rogue Valley, as we’ll likely see cloudier skies AND the best part, would keeps highs in the upper 80s vs. low 90s.
Saturday most storms will fire in the Eastern Cascade slopes so mainly a threat for Central Oregon. However, wildfire concerns are high right now given the extrememly dry nature of the air and ground, lightning strikes may occur away from the main clouds and increase threats for new fire development. Sunday, another (stronger) low pressure slides up the coast, with the best threat for storms to fire in the Central and Northern Willamette Valley. Highs over the weekend will climb back into the low 90s.
Early next week, the ridge strengthens and we’re looking at mid 90s inland from Monday through midweek. No rain chances (aside from thunderstorms) nor a break from the heat is likely anytime soon.
Have a great Thursday night!
