Good day, sunshine!
We had gotten used to waking up to a cozy blanket of morning clouds over the last few days, but we lost our over-coating of overcast on early Saturday. Without it, the sunshine went straight to work, warming us much more quickly. The result? A spectacular Saturday afternoon around Puget Sound, with afternoon highs in the middle to upper 70s.
Like it warmer? Sunday will be "perfect at the pool", with temperatures soaring into the middle 80s from Vashon Island to Mercer Island. Not a bad way to wrap up a weekend!
Higher pressure will build up over the west coast, and as it grows, it will warm us up further. The sinking air beneath the high will push any would-be clouds out of the way, including any that try to form over the ocean beaches. As the coastal stratus melts away, we lose our natural air-conditioning, and that will allow all of Western Washington to warm up. Highs will warm into the upper 80s to low 90s around the Seattle metro area by early next week, which is about the same level we had during the wave of warmth last weekend. The difference this time is that the heat will hang on quite a bit longer, with at least 80s, if not 90s, forecast through the rest of the week.
This warm streak will lead to a round of higher fire danger, especially east of the Cascades, where temperatures will surge into the 90s and triple digits. We'll see similar toasty temperatures in much of Oregon, and an EXCESSIVE HEAT WATCH is in place in much of the Willamette Valley around Portland and Eugene.
So: toss off your bed blankets for now, and grab a beach blanket instead! Late July will be a hot one here in the Pacific Northwest.
Have a great night,
