“Giving you the reasons why Eastern Sierra weather happens.”

FRIDAY April 20, 2012

Substantial warm-up in store for us through Sunday, as a building ridge of high pressure nudges overhead. There still exits a slight chance of afternoon and evening thunderstorms over the Crest today and Saturday.  The ridge moves east on Sunday, setting up a dry South West flow over California through mid next week. A fairly strong storm from the Gulf of Alaska will then drop south into the PACNW late Wednesday. Most of the moisture should stay to our north, but there is a chance some will make its way southward. Stay tuned for updates on this.

BTW: With the wet conditions so far in April, the State of California Snow Water Equivalent is now at 67% of normal.
