June 29, 2019
Summary: The main feature of note this morning is rapidly weakening tropical storm Alvin which is literally unwinding. Mid and high level moisture from Alvin is now caught up in the southwesterly flow aloft and is transporting abundant cloud cover into southern California and Arizona. Interestingly, models show the northern edge of the cloud mess in the southern San Joaquin Valley tonight and Sunday morning, but no precipitation will occur. Otherwise, a trough of low pressure remains anchored over the Pacific Northwest and will remain there at least through the middle of next week and possibly through the Fourth of July. This will mean a dry westerly flow aloft will continue Monday through Wednesday. Temperatures will hover near to marginally below seasonal averages for early July.
Most models by next weekend are indicating upper level high pressure will be off the southern California coast interconnecting with another high building over the Desert Southwest. We could see triple digits as early as next Friday with a greater risk of hot weather next weekend. This pattern could also signal the return of the monsoon season as some models are showing moisture from old Mexico moving into Arizona and New Mexico about the sixth, which would be more or less typical this time of year. For now, none of this moisture is projected to move into central California.
Forecast: Mostly clear today. Variable cloudiness tonight and Sunday morning, mainly from Hanford and Visalia south. Mostly clear skies Sunday afternoon and on through Saturday of next week.

Two Week Outlook: July 5 through July 11: This model is indicating high pressure at the upper levels of the atmosphere building over the Desert Southwest and expanding northwestward into California. This pattern is conducive for above average temperatures, meaning triple digits. So far, it looks like the winds aloft will remain southwesterly so dry conditions will prevail.
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: During the afternoons and evenings, winds will be mainly out of the northwest at 8 to 15 MPH with stronger gusts through Tuesday. During the night and morning hours, winds will generally be in the 5 to 10 MPH range with periods of near calm conditions.
Rain: Expect dry conditions for the next 7 to 10 days.
