The recent reprieve from the heat will end abruptly next week, as a summer-like ridge of high pressure builds into the region. Before that happens, relatively cool weather will continue on Saturday, as a chance of showers lingers especially in western areas. Although Sunday morning could be quite chilly in spots, temperatures will rebound nicely by afternoon. By the middle of next week, many areas should rise well into the 80s, with mild lows in the 50s as well. The trend will generally be toward sunny and calmer conditions next week.

Right now, it appears that the coast may not be quite as warm as it was during the last hot spell, while peak temperatures east of the Cascades will be slightly warmer than those experienced on May 1/2. Even so, most western areas will soar to well above normal readings. Sometime around next Thursday or Friday, the hottest areas of Washington should top out in the low 90s. Even the mountains will be subject to significant warming. Daytime temperatures at pass levels will rise from the 40s on Saturday to at least 70 degrees by mid to late next week. The warm high pressure ridge may weaken next weekend, although the magnitude and timing of the cooling is uncertain at this time.
