The Bay Area will experience a cooling trend beginning Saturday, as the National Weather Service anticipates lower temperatures next week. A short-wave high-pressure ridge is currently in place but is being flattened by an upper-level trough, affecting temperature patterns differently than previous trends. Despite a long-term ridge potentially building later in the month, temperatures will remain below-normal for now. Specific areas like Brentwood and Antioch are forecasted to exceed 100 degrees, while other areas will see temperatures rise but remain less intense.
Right now, we're under the effect of a short-wave high-pressure ridge. But that ridge already is starting to be flattened by upper-level trough activity.
This upper-level trough is a different one in its movement than the trough pattern that hung out in the upper atmosphere for much of June.
It's not completely unusual. It's still relatively early in the summer, and the best chance for a thicker ridge and longer-term event might be the end of the month.
Temperatures in some areas of the interior East Bay will exceed 100 degrees. Brentwood is expected to pace the region with a high mark of 105.
