July 3, 2019
Summary: Low pressure remains centered over Oregon this morning with a weak trough down into northern and central California. The winds aloft remain out of the west/southwest and there are a few high clouds embedded within this flow that will be visible from time to time. A rather robust onshore flow continues and it is still allowing modified marine air to move down the valley from time to time. Winds near the top of the dam at Pacheco Pass were out of the west sustained at 20 MPH at last report. Temperatures will remain somewhat below average through the Fourth of July then will begin to rise Friday as the trough weakens and retreats back into the Pacific Northwest. Warmest locations Saturday and Sunday will end up near the century mark.
Another downturn in temperatures will occur Monday and Tuesday as the trough again becomes reestablished down into northern and central California. This will be a temporary situation as we all know moderate temperatures do not last long during the month of July.
Models continue to trend towards a strong high developing over the Desert Southwest, expanding northwestward over California and as far north as the Pacific Northwest. This will begin to drive temperatures into the triple digits by Wednesday or Thursday of next week, setting up a prolonged period of typical valley hot weather. By next weekend, the flow aloft will become out of the southeast, possibly allowing limited amounts of moisture in for the possibility of thunderstorms over the high Sierra. No precipitation is expected on the valley floor for the foreseeable future.
Forecast: Mostly clear skies through Saturday. Mostly clear Sunday through Wednesday.

Two Week Outlook: July 10 through July 16: The trend the past couple of model runs is for dominant high pressure over the western one-third of the U.S. This will result in above average temperatures during this time frame with the usual dry conditions continuing.
July: July, of course, is typically hot and if this model has any credence, it will be hotter than average. With a dominant Four Corners high and a trough over the middle of the country, usual July dry conditions will prevail.
July, August, September: This model is indicating that the western U.S., including California, will experience above average temperatures overall during the mid to late summer period. Precipitation is expected to be near average, which, of course, is very little and there’s no reason to believe otherwise.
Winds: Winds will be mainly out of the northwest afternoons and evenings at 8 to 15 MPH with gusts to 25 MPH possible. Winds during the night and morning hours will be generally out of the northwest at 5 to 10 MPH with stronger gusts through Saturday.
Rain: Expect dry conditions for the next 7 to 10 days.
