Summary: upper level high pressure remains over California. It extends westward well off shore and eastward into the Rocky Mountain region. The only inclement weather along the west coast is over Washington state which is dealing with a weak area of low pressure. That low will slowly develop a trough down into California. By midweek, it will extend from British Columbia southward through central California. Typically, this time of year these types of disturbances this far south are dry, and this will be no exception. However, the air aloft will begin to cool and the marine layer along the coast will deepen, allowing the marine air to spill inland with noticeably cooler weather beginning Wednesday as readings drop into the mid to upper 80s. Currently, the marine layer stands at 1,900 feet which is already moderately deep. However, surface pressure patterns will be flat through Tuesday, meaning there will be no trigger to nudge that modified marine air inland. Thus, mid to upper 90s will continue through Tuesday. The rapidly melting snow pack will release enough water vapor for a chance of isolated thunderstorms this afternoon and again Tuesday afternoon over the high Sierra. Otherwise, dry weather will prevail for the next week to possibly ten days.
Forecast: Mostly clear skies through Thursday night. Mostly clear skies will continue Friday through Monday.

Two Week Outlook: May 9 through July 4 This model projection indicates a weak trough of low pressure will be over central California. It may allow enough modified ocean air to enter to bring temperatures down to average levels. There will be a chance of afternoon and evening thunderstorms over the higher elevations of the Sierra Nevada, but no precipitation is expected on the valley floor.
May: This model continues trends during the month of May that we saw in April. Pressures will be lower than average along the west coast, resulting in the chance of above average rainfall and below average temperatures
May, June, July: This model doesn’t really move the needle either way for temperatures and rainfall over the next three months. being that we’re heading into the hot, dry season, it means little anyway.
Wind Discussion: Winds will be mainly out of the northwest at 5 to 12 mph afternoons and evenings through Tuesday, decreasing to 3 to 7 mph during the night and morning hours with periods of near calm conditions. Winds Tuesday night through Thursday will be mainly out of the northwest at 8 to 15 mph with gusts to near 20 mph, especially during the afternoon through the late evening hours.
Rain Discussion: Expect dry weather for the next week to 10 days.
Mid afternoon dew points: Low to mid 50s. Kern: Upper 40s to the lower 50s.
