Hot temperatures will continue under strong high pressure Thursday and Friday. High temperatures will be running around 20 degrees above normal for this time of year. If you need to be outdoors during these warm temperatures be sure to stay hydrated and protect your skin by wearing sunscreen and loose, light colored clothing. NEVER leave pets or children in vehicles during these hot temperatures. Cracking windows is useless and offers no relief for living beings trapped in vehicles. A drastic cooldown is on the way for Saturday where high temperatures will return to normal and be around 20 degrees cooler than Thursday’s and Friday’s highs.

Low pressure will move into the area late Friday night into Saturday, bringing a drastic change in the weather for the weekend. After a period of hot temperatures, much cooler temperatures will be in place; on the order of 20 degrees cooler. This system will bring significant rainfall, possibly challenging some daily record totals for areas west of the Cascades. In addition to the beneficial precipitation, there will be chances for thunderstorms late Friday through the day Saturday. As this system moves through the area Saturday afternoon, strong winds are possible east of the Cascades. If you have outdoor plans on Saturday, you should consider rescheduling as it will be a rather soggy day. Plus with the possibility of thunderstorms across the area, it won’t be safe to be outdoors. Remember, “when thunder roars, go indoors!”
