August 10, 2019
Summary: Today will be the coolest we will see for quite some time. Most locations will not reach the 90 degree mark this afternoon. At the surface, there’s roughly a 7 millibar difference in pressure between San Francisco and Las Vegas, which means a relatively strong onshore flow will continue. At the upper levels of the atmosphere, low pressure is centered near Eureka this morning and will move in during the course of the day. The air aloft has cooled somewhat as well with the latest freezing level over Vandenberg at 13,900 feet.
The traditional Four Corners high has shifted into Texas, but it will begin to migrate towards the west again Monday, settling over southern New Mexico and Arizona by midweek. Monday will be noticeably warmer with Tuesday and Wednesday topping out possibly as high as the lower 100s.
The positioning of the high will block moisture from the monsoon, preventing it from moving into California for at least the next week. By Thursday, a new low will develop just west of the northern Oregon coast. It will eventually form a trough into northern California. This will result in yet another strong onshore flow and lower pressures aloft for another round of below average temperatures Thursday, lasting through the following weekend. It does not appear temperatures will fall below the 90 degree mark.
Forecast: clear skies through Sunday and quite mild. Clear and warmer Monday through Wednesday. mostly clear and somewhat cooler Thursday through Saturday.

Two Week Outlook: August 17 through August 23: This model is projecting the triumphant return of our Four corners high, resulting in somewhat above average temperatures. There will be a small chance of thunderstorms over the high Sierra, but the rest of central California will remain dry.
August: This model projects fairly persistent upper level high pressure over the Desert Southwest. The monsoon shows up, as it typically does this time of year, but it generally produces little to no precipitation over the valley. The bottom line, temperatures will be marginally above average with typically dry conditions.
August, September, October: The 90 day outlook doesn’t really give strong indicators one way or the other. As far as precipitation is concerned, this model is projecting near average totals for the next three months. This model also projects above average temperatures for much of the western U.S.
Winds: Winds will be out of the northwest through this evening at 10 to 15 MPH with local gusts to near 25 MPH possible. Along the Interstate 5 corridor, winds as strong as 35 MPH are possible. Winds later tonight through Tuesday will be generally less than 15 MPH with periods of near calm conditions, mainly during the night and morning hours.
Rain: Expect dry conditions for the next week to ten days.
