SAN DIEGO (KGTV) - Another round of thunderstorms could hit San Diego County’s mountain and desert areas as this week’s hot-and-humid spell continues.

According to Megan’s forecast, San Diego’s sticky and uncomfortable conditions will be replaced with cooler and drier air as we head into the weekend, thanks to a “trough of low pressure pushes” over the West Coast.
