July 15, 2019
Summary: Even though it will be hot today, with most locations around the century mark, it will not be as hot as we observed over the weekend. Upper level high pressure is currently centered near the Arizona/New Mexico border, but is flattening out over its northwest flank due to a weak trough of low pressure moving into the Pacific Northwest. As a result, temperatures will incrementally come down as we move through the week, finally bottoming out Friday and Saturday with most locations in the low to mid 90s. the current level of the marine layer is only 1,100 feet deep, but that will increase, allowing a shallow intrusion of modified marine air to make it down the valley after midweek. Medium range models for next week are showing the possibility of a big ridge developing over the western states with its center over the Four Corners region. If this does happen, triple digits would again occur. The winds aloft rotating clockwise around the high would also be out of the south, possibly the southeast, which would favor monsoon moisture working its way into southern and central California. This would also favor afternoon and evening thunderstorms over the Sierra Nevada. It will be interesting to see if this trend continues on models as we progress through the week.
Forecast: Clear skies through Thursday and not as hot. Mostly clear Thursday night through Monday.

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 light this morning. This afternoon, winds will be out of the northwest at 10 to 15 MPH with local gusts to 25 MPH, mainly along the west side. Winds tonight will be out of the northwest at 5 to 15 MPH. Winds Tuesday through Thursday will be mainly out of the northwest at 5 to 15 MPH with local gusts to 25 MPH, mainly in the afternoons and evenings.
Rain: Expect dry conditions for the next 7 to 10 days.
