Summary: Upper level high pressure continues to be centered near the Arizona/New Mexico border. The other item of interest is a weak trough of low pressure over the Pacific Northwest extending southward into northern California. This will keep a dry, west/southwest flow going. The fact that central California is essentially between the high over the southwestern U.S. and weak low pressure to our north means temperatures will be fairly close to seasonal levels through Wednesday. The trough will be reinforced Thursday night through Saturday by another impulse moving into the Pacific Northwest which will lower temperatures a tad below average for mid July. Most locations Friday and Saturday will only top out in the low to mid 90s.
Hot weather is on the horizon, however, as there is a definitely trend indicating strong upper level high pressure will build over the Four Corners region beginning Sunday. It will expand northward and westward for much of next week. Again, central California will probably end up on the western periphery of this high which will drive temperatures into the lower hundreds. Winds aloft by Monday will be southerly, so any monsoon moisture which happens to be over northwest Mexico by early next week could be transported northward into central and southern California. Typically, this results in daily chances of scattered to isolated thunderstorms over the Sierra Nevada and isolated storms over the mountains and deserts of southern California. No precipitation is expected on the valley floor, but we may see mid and high level clouds from time to time.
Forecast: Clear skies through Thursday. Mostly clear Thursday night through Sunday night. mostly clear to occasionally partly cloudy Monday through Tuesday.

Two Week Outlook: July 22 through July 28: This model shows the main heat belt from the Rocky Mountains eastward while a weak trough is along the west coast. Since this trough is unimpressive, temperatures will remain near average with no chance of precipitation.
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 generally out of the northwest at 8 to 15 MPH afternoons and evenings through Friday with local gusts to around 25 MPH. during the night and morning hours, winds will be generally out of the northwest at 5 to 10 MPH.
Rain: Expect dry conditions for the next 7 to 10 days.
