Another upper atmospheric blast of monsoonal moisture was heading toward the San Francisco Bay Area Monday, bringing with it a chance of thunderstorms.
While the chance of a thunderstorm remains at just about 15-20 percent, the thought of even one lightning strike in the tinder-dry, drought-stricken hills sends anxiety levels soaring among local residents and firefighters. “Large monsoonal thunderstorms have been allowed to develop over the desert Southwest over the recent several days, with the latest being a massive convective complex that rampaged through Vegas last evening and is now bearing down on Los Angeles early this morning,” the National Weather Service said in a Monday forecast update.
