Weather: Still hot, but drier
Triple-digit heat returns Friday to parts of inland San Diego County, but lower humidity levels should mean less potential for thunderstorms, lightning strikes, fire starts and flash flooding.
“Today is going to be drier, less humid, with a slight chance of thunderstorms in the mountains and deserts,” National Weather Service meteorologist Don Whitlow said. “It will be hotter today because there will be less cloud cover and moisture in the air.”
Coastal areas will remain temperate with forecast highs around 80 in San Diego and Oceanside, according to the Weather Service.
Further inland, Escondido and Julian will see highs around 90. In the desert, the forecast high in Borrego Springs is 115,, according to the Weather Service.
Peak heat levels in vulnerable areas during the current warm spell may last through the weekend, according to San Diego forecasters.
For desert areas where temperatures are expected to crest over 110, the Weather Service routinely issues excessive heat warnings.
“Excessively hot temperatures can be stressful to animals and humans ... making it hard for the body to acclimate and remain hydrated,’' the Weather Service said in a statement.
“Extremely warm overnight low temperatures do not allow the body to cool down properly overnight . . . and can make extreme heat even more dangerous,’' an excessive heat watch statement said.
