The overall weather pattern is still governed by weak features. A weak trough of low pressure extends from Montana southwestward into southern California while weak upper level high pressure governs the eastern Pacific into northern California. Satellite imagery shows high clouds moving into southern California on a weak southwesterly flow aloft with another batch of high clouds over northern California. Most of central California is largely clear. This basic pattern will remain in place through the weekend. Since there is no feature strong enough to allow marine air into the valley, temperatures will remain marginally above average. It does appear, however, that a short period of hot weather will prevail Monday through Wednesday of next week. Models place the center of circulation of a strong upper high just west of San Francisco Monday, moving inland Tuesday and Wednesday. if models continue on this trend, readings will jump into the mid 90s Monday then heat into the lower 100s Tuesday and Wednesday. typically during the month of May, 100 degree heat is short lived and that will be the case this time around as a trough of low pressure will move into the Pacific Northwest and northern California Thursday of next week, allowing a strong push of marine air to move inland along with cooler weather aloft.
Forecast: Mostly clear skies through Saturday. Mostly clear Saturday night through Wednesday.

Two Week Outlook: June 2 through June 8: This model is indicating a zone of upper level high pressure will dominate the western 1/3 of the US during this time frame, resulting in above average temperatures. The typical dry conditions will continue.
June: This model is indicating a ridge of upper level high pressure will be more dominant over the Desert Southwest and, to a lesser extent, California, resulting in above average temperatures for the month with the usual dry conditions prevailing.
June, July, August: This model mimics the pattern of recent years, indicating high pressure over the Desert Southwest being the most dominant feature, resulting in above average temperatures. Theoretically, this pattern blocks monsoonal moisture from moving northward. Typically, there’s little to no precipitation anyway, and that will be the case this summer.
Winds Discussion: Winds during the afternoons and evenings will be mainly out of the northwest at 8 to 15 MPH with locally stronger gusts. Winds during the night and morning hours will be mainly out of the northwest at 5 to 10 MPH with periods of near calm conditions, through Saturday.
Rain Discussion: Expect dry conditions for at least the next 7 to 10 days.
Afternoon Dew Points Today: Low to mid 40s. Upper 30s to the lower 40s.
