The weather pattern along the West coast from Washington state to California is very dull. In general, there is a ridge of high pressure at 500 mb in control.
This high is providing warm temperatures away from the immediate beaches but not excessively hot weather as we had in portions of Southern California late last week and over the weekend. Temperatures will be averaging above normal.
There is a broad and relatively weak, closed low well west of the southern Oregon/northern California coast. While this spins well offshore the next couple of days, it will eventually head east by Friday and the weekend. Models are in agreement on this. What they are not in agreement on is how far south the low will go. The main effect on the weather would be on how much cooler air occurs, especially in central and Southern California. Precipitation is not going to be much, though there could be a mainly afternoon shower or thundershower in a few spots over Oregon, northern California and northern Nevada. Monsoon moisture is not going to be a player.
With approximately 1.6 million acres burned so far this is about 600,000 acres less than last year
Within the three-state area of Washington, Oregon and Idaho, there are 21 large fire incidents ongoing.
The water level on this massive reservoir had never been lower than what was reached on July 9.
It has been pretty hot of late in the interior Northwest but even hotter weather looks likely by Sunday and Monday.
It does not usually rain this time of year; when it does, this is usually how it happens.
This is the beginnings of the summer monsoon pattern that typically starts around the first week in July.
