It is going to be a great weekend!
Temperatures should climb to around or above 25°C Friday, Saturday and Sunday according to both EC and UWash. Orange areas below are 24-26°C (76-80F).
The hottest day will be Sunday according to UWash but Saturday according to EC. Either way, it witll be warm both days.
There will be a chance for showers in the afternoons, particularly along the mountains on Saturday and Sunday. Sunday there is actually strong showers in the UWash models possibly associated with Thunderstorms building from about 2PM onward.
Monday and Tuesday look like a washout. 😐 So enjoy the sun while you can!
