A high pressure ridge (“Arch” shaped section of shaded area over western Canada and the Rocky Mountain states) has taken over and will be keeping the rain away for a quite a while. A weak frontal system has moved down the ridge and into the Pacific Northwest , but all it is doing is cool us down a bit and then about mid week we could see a chance of showers as an upper level trough of low pressure approaches. Summer officially begins a week from Monday June 21st at 4:28 AM Pacific Daylight Time.

Advisories: NONE AT THIS TIME.
