Summary: The trough of low pressure which resulted in a strong push of modified marine air into the valley has now moved into the Rocky Mountain region. Winds at Traverse Air Force Base in the Delta are southwest at just 6 MPH, meaning the flow of cooler air into the valley is over for a time. The marine layer itself has shrunk back to 1,500 feet.
Upper level high pressure over the eastern Pacific is beginning to nose into northern and central California. This will result in noticeably warmer weather today with readings peaking out at or just above the 100 degree mark tomorrow and Monday. Fortunately, the center of the high will remain off shore, meaning no excessively hot temperatures are expected.
By Monday night, the high will begin to flatten out over northern California in response to a low moving out of the Gulf of Alaska. It will eventually be off the Oregon coast Wednesday then will move into the Pacific Northwest with a trough of low pressure stretching down into northern and central California. There will be a dry southwest flow aloft underneath the low and into central California. At the surface, a strong push of marine air inland will occur beginning Tuesday with very mild weather Wednesday through Friday of next week.
By next weekend, a flat zone of high pressure will move in from the west, nudging temperatures back up to near seasonal levels. There is definitely a trend developing on upper level high pressure developing over the Four Corners region during the first few days of July. Typically, this pattern results in hot weather for central California, but currently it appears the so far non existent monsoon this season will be suppressed to our south.
Forecast: Mostly clear skies through Wednesday. Continued to be mostly clear Wednesday night through Saturday.

Two Week Outlook: June 28 through July 4: This model shows the possibility of high pressure building over the Four Corners region. If this happens, we may see fairly hot weather during this time frame 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 at or less than 15 MPH afternoons and evenings through Monday and mainly out of the northwest. During the night and morning hours, winds will be generally at or less than 10 MPH with periods of near calm conditions. Winds Tuesday will be mainly out of the west to northwest at 10 to 15 MPH with possible gusts to 25 MPH, mainly along the west side.
Rain: Expect dry conditions for the next 7 to 10 days.
