Hotter weather is back to end the month with excessive heat in our deserts.

August is typically our warmest month, and that is how it will end with temperatures trending trend 5 to nearly 10 degrees above normal for our inland communities, foothills, and deserts.

The heat peaks Thursday and Friday. An Excessive Heat Warning has been extended until Sunday at 9pm. Temperatures will average between 110 to 115 degrees, with 80s and 90s into the overnight hours. The warmer coastal areas will see 80s while inland areas will warm well into the 90s inland with low 90s in the mountains.

It will be a drier heat, with a shallow marine layer. Coastal areas will see few clouds, and the rest of the county will be hot and sunny. As temperatures go up and humidity stays low, it elevates fire danger. So, it is recommended to avoid power tools or anything that could potentially spark or start a flame.

Hazy skies continue due to smoke moving south from the fires burning in Northern Califonia. Air quality will drop to Unhealthy for Sensitive Groups. Areas to monitor include Alpine, El Cajon, and Escondido. If you want a closer look at the air quality numbers, check out the forecast at the Air Pollution Control District.

Temperatures will stay warm through the weekend; humidity will be trending upward on Sunday into early next week making it feel hotter and uncomfortable but also triggering showers and thunderstorms. The best chance for showers and thunderstorms will be Monday through Wednesday, for our mountains and deserts. We can't rule out the possibility of storms to break off and travel west into our valleys.

Our ABC 10News Pinpoint Weather Team will keep you up to the latest as monsoonal thunderstorms develop, and bring possible heavy rain. This may not be the last of monsoonal storms, we could see more events before the end of Summer. The average monsoonal season can last until September 30th.

Coast: 78-83°
Inland: 88-94°
