Summary:
- June held true to forecast with relatively mild temperatures over most of the west, with portions of California warmer than average and portions of Washington and extreme southern California cooler than average.
- Precipitation over the western US during June produced a slightly wetter than average north and much drier than average south.
- Short to long term drought concerns are forecast to remain in place or develop further for much of the west.
- The short-term forecast is pointing to seasonal conditions with onshore flow and marine layers in the western valleys and a generally cool month for all. No rain to speak of for all except maybe the extreme NW of Washington. Warmer second half of month likely over the west, but extreme heat does not look likely.
- The July through September seasonal forecast continues to point to the likelihood of a warmer than average period for much of the western US. The overall precipitation outlook is pointing to average conditions, which in the summer is dry overall. However, a precipitation event or two due to thunderstorms is highly likely later in the summer.
