July 30, 2018
Summary: Here we go with a brand new week with the string of 100+ degree weather continuing probably through Saturday. The high center has shifted just a little further east, allowing a southeast flow to move into southern and central California. This flow is pumping a minimal amount of monsoonal moisture over central California. This moisture will only add partly cloudy skies on the valley floor through Tuesday night. There will be an increased chance of thunderstorms over the higher elevations of the Sierra Nevada. Even that will begin to taper off on Wednesday, though.
The marine layer this morning is only 1,000 feet deep. It’s’ trickling through the Delta but with that strong high just to our southeast, there is no chance of that sea breeze affecting the central or south valley.
On Wednesday, the winds aloft will tilt from a southwesterly direction, nudging the monsoonal cloud cover into the Nevada. Model information suggests a southwest flow from Wednesday on, so even over the Sierra Nevada, thunderstorm activity will be minimal at best.
There is a chance of double digit temperatures early next week. A trough of low pressure will develop off the coast of the Pacific Northwest and, depending upon how far south this trough develops, there may be some influence on our temperatures. For now, it appears we may dip into the upper 90s Monday and possibly beyond to end this ridiculous string of 100+ degree weather.
Forecast: Mostly clear to occasionally partly cloudy through Tuesday night and continued hot. Mostly clear Wednesday through Monday of next week and continued hot.

Two Week Outlook: August 6 through August 12: Expect a continuation of hot conditions over central California and the southwest. Monsoonal moisture may occasionally make its way over southern California from time to time. For now, though, it looks like generally clear skies will remain over central California.
July: This model is indicating high pressure over the Desert Southwest will be stronger than usual. A fairly active monsoon is also indicated for periods of thunderstorms over the Sierra and hotter than average temperatures over the valley floor.
July, August, September: Like the 30 day outlook, this model is indicating we’ll have a hot summer, moving into the early fall. Above average precipitation is possible over southern California and the Sierra Nevada due to an active monsoon season with temperatures remaining generally above average for the next three months.
Winds: Winds will be generally at or less than 15 MPH through Thursday and mainly out of the northwest afternoons and evenings.
Rain: Expect dry conditions for the foreseeable future.
