The strong high pressure area is still over the western U.S. The southerly flow around the westside of the high has tapped a good source of subtropical moisture and is pulling it northward over California. The moisture mixed with the hot and unstable airmass over our area is triggering widespread thunderstorms. The thunderstorms will continue today. Tuesday the storms will be along and east of the Sierra Cascade Crest. Gusty west to northwest winds will occur in some areas today and Tuesday.
The high looks like it will remain over the western U.S. for the next 7 to 10 days (see map below). Wednesday and Thursday temperatures will be slightly above normal. However, by the weekend and early next week we will see temperatures back to 5 to 10 degrees above normal. It looks like another surge of subtropical moisture could be pulled northward late in the weekend or early next week.
