June 19, 2023

Summary: Temperatures compared to 24 hours ago are down 8 to 10 degrees on the valley floor. a strong push of modified marine air has been underway for the past day and will continue from time to time through midweek, driving temperatures well below average. In some cases, readings will drop a good 15 degrees over their Saturday values. A rather robust low pressure system stretches from the Canadian Rockies southwestward to northern California. At the surface, pressures are considerably lower over the Great Basin than off shore. As of 5:00 am, the altimeter reading at San Francisco was 29.94 inches of mercury as opposed to 29.67, illustrating the strong on shore flow. California will pretty much be under a dry southwest flow aloft around the bottom side of the low. By Thursday morning, the low will begin to weaken with a weak upper low tagging behind over northern California. This will allow temperatures to slowly begin to recover by mid week, however temperatures will remain sub 90 degrees through Saturday. By early next week, pressures aloft will have risen enough to allow temperatures to approach seasonal averages which at this time of year is around 93 degrees.

 

Forecast: Mostly clear and mild through Thursday. Mostly clear Thursday night through Monday with a slow warming trend.

Two Week Outlook:  June 26 through July 2  This model is beginning to depict a high center developing over extreme over Mexico and southern Arizona and New Mexico, theoretically baking the Desert Southwest. Central California will be on the far northern fringe of this high, resulting in slightly above average temperatures and dry conditions.

 

June:  Of course, this time of year, 30 and 90 day outlooks are virtually useless as they’re essentially the same every year. Basically light all day and hot and light all night and warm. Essentially for June, near average temperatures and dry..

 

June, July, August:  The 90 day summary outlook is the same this year as it is every year. Generally dry with somewhat above average temperatures. The monsoon season hasn’t begun yet, so we’ll start taking that more seriously down the road.

 

Wind Discussion: Winds through Tuesday evening will be out of the northwest at 10 to 20 mph with local  gusts to 35, especially along the west side. Somewhat lighter winds can be expected during the later night and morning hours. Winds Wednesday and Thursday will continue to be mainly out of the northwest at 8 to 15 mph with gusts to 20 mph, mainly in the afternoon and evening.

 

Rain Discussion: Expect dry conditions for at least the next week.
