A heat advisory is in effect for parts of San Diego County until 8 p.m. Tuesday, according to reports from the National Weather Service.
High temperatures of 95 to 102 are forecast for San Diego County valleys, El Cajon, Escondido, San Marcos, La Mesa, Santee and Poway.
Hot cars are always a concern when the temperatures crank up. Meteorologist Dagmar Midcap says when it's 90 degrees outside it only takes the inside of a car with the windows rolled up 10 minutes to reach 109 degrees. After 20 minutes, it''ll be around 120 degrees, and after 30 minutes, it could be as hot as 129 degrees. Wait an hour and you could see temps in your car climb all the way to 133 degrees, so be mindful of children or animals being left in your vehicle -- look before you lock, Midcap says.
Residents of East County should also be aware that afternoon thunderstorms are possible for the mountains both on Monday and Tuesday, according to NBC 7's Sheena Parveen.
It is expected to be slightly cooler on Tuesday and Wednesday.
An isolated thunderstorm on Sunday over southeastern San Diego County produced 17 cloud-to-ground lightning strikes and 94 in-cloud flashes in about 30 minutes from 7 to 8 p.m.
