THU  MAY 21 2015

Longwave trough continues to camp off the West coast. As such, it will send a series of shortwaves inland, bringing unsettled weather to our entire forecast area. So showers & thunderstorms are possible, mainly in the afternoons and evenings thru Friday. A general decrease in shower activity over the weekend as the longwave trough moves east. But another system, running down the backside of the departing trough, looks to head thru the PACNW over the weekend. So I will throw in a chance of showers & thunderstorms along the Sierra Crest thru Memorial Day, under partly cloudy to mostly sunny skies. Stay tuned for updates on this.

Owens Valley:

Today: 40% chance of showers & thunderstorms. Highs 68 / Lows 42. Winds SE 10 – 15 mph.
