August 5, 2017
Summary: The main feed of monsoonal moisture has moved northward into northern California. An upper level low is moving slowly northward along the northern California coast. Most of central and southern California cleared as a drier air mass associated with a west/southwest flow aloft is pushing the remainder of the monsoon east of southern California.
Temperatures will move into the lower 100s in most areas today as abundant sunshine will prevail with near average temperatures expected for the first part of next week. As high pressure builds marginally, 100 to 105 degree weather will occur from Wednesday through next weekend. Temperature forecasting for next weekend might be a challenge. Some models show an upper level low parking right off the central coast, deepening the marine layer and also causing some cloud cover to be flung over the region. For now, I’m operating under the assumption that the low will be too far to the west to have much of an impact with temperatures remaining in the 100 to 105 degree range.
In the medium range, it appears either a west or southwest flow will prevail with no chance of the monsoon returning next week and more than likely the following week.
Forecast: Other than occasional cloudiness, it will be mostly clear through Tuesday. Mostly clear Tuesday night through Saturday.

Two Week Outlook: August 12 through 18: Models show upper level high pressure again building over much of the west. This should result in another round of above average temperatures and possibly the return of the monsoon. Overall, conditions will be dry.
August: This model shows a significant trough of low pressure east of the Rockies and overall fairly strong high pressure dominating the western third of the U.S. This should create above average temperatures for the month with a chance of the return of the monsoon from time to time. Generally, temperatures will be above average with a slight chance of isolated showers and thunderstorms.
August, September, October: The trend towards above average temperatures shows up once again through at least August and September. October is more iffy. As far as precipitation is concerned, conditions will remain near average. Remember, the real rainfall season doesn’t begin until November so no significant amounts of precipitation are seen at this time.
Winds: Winds will be generally less than 15 MPH through Monday.
Rain: Expect dry weather for the foreseeable future.
