Lots of sun except for Sunday, but at least it won’t be raining on your picnic.

The good news is that a high pressure ridge (“Arch” shape) is moving in bringing us sunshine and much warmer temperatures for the long holiday weekend. A weak disturbance Saturday night and Sunday will bring clouds and no precipitation to Oregon, but that will cool down the temperatures more than I originally thought. More sunshine and warmer for the 4th.
