Coastal Cooling, Heat Inland

After high temp records fell in parts of the North and East Bay to start the weekend, Sunday is shaping up to be another hot day inland with highs again soaring into the 90s and 100s away from the bay. There is some hope for slight cooling near the beaches and into the inner bay thanks to a slightly stronger sea breeze for Sunday. This brief respite won’t last long as high pressure reaches its peak Monday into Tuesday. This means our inland temps will likely resume their upward climb, into the 105-110 range through midweek. As if that’s not enough to be concerned about, there’s also now a risk for elevated convection ( dry lightning ) late Monday night into Tuesday. The increased mid-level to upper level clouds may drop temps slightly from what s currently in the forecast now for Tuesday, however this could complicate fire danger concerns if enough of this high level moisture streams over the Bay Area. It will be far too dry in the lower levels of the atmosphere to support any rainfall, therefore lightning-sparked fires may become a concern. This will need to be watched closely early this week. Cooling will probably take a little longer to arrive for our inland areas, with temps hanging on to the 90s to near 100 now through 4th of July. Typical of supersized, strong ridges of high pressure the forecast models sometimes tend to break down these ridges too fast. For now its looking like inland areas should see more noticeable cooling by Friday into Saturday. Rob Mayeda
