Cooler Temperatures Forecast For SoCal
LOS ANGELES, Calif. (KTLA) -- Cooler temperatures are forecast for Southern California Friday, ending an extended heat wave that sent the mercury soaring into the triple digits.

Expect a 10 to 15 degree reduction in highs as the onshore flow strengthens and pressure drops on Friday. Morning low clouds and fog will develop and spread over portions of the coastal plain. By mid-morning skies will be mostly clear across the region. Look for a temperature range from the low 70's at the coast to mid 90's in the valleys.

Saturday the cooling continues, with the addition of more clouds, as low pressure settles over Southern California. There is a slight chance of showers across the region; although we're expecting most of the activity inland over the mountains and deserts. Under partly cloudy skies, expect daytime highs near 80 degrees for metro Los Angeles and Orange Counties. The valleys should expect pleasant highs in the upper 80's to lower 90's.

Winds could become an issue into the weekend with low pressure creating stronger gradients. Wind Advisories may be need for the upper deserts and for the mountains.

The Los Angeles County Health Officer is reminding everyone that precautions should be taken, especially by those people sensitive to the heat.

"While people don't need to be told it's hot outside, they do need to be reminded to take care of themselves, children, the elderly, and pets when the weather gets hotter," said Jonathan E. Fielding, MD, MPH, Director of Public Health and Health Officer. "When temperatures are high, prolonged sun exposure may cause dehydration, heat cramps, heat exhaustion, and heat stroke. Never leave children, elderly people, or pets unattended in vehicles, even with the windows 'cracked or opened,' because temperatures inside can quickly rise to life-threatening levels. It is illegal, according to California law, to leave children alone in a car."

Also check on elderly neighbors and seek shade or air conditioned buildings during the hottest part of the day, the NWS warned.

If you plan to be outdoors, take precautions to protect yourself from the heat. Symptoms of dehydration and heat cramps include dizziness, fatigue, faintness, headaches, muscle cramps, and increased thirst. Individuals with these symptoms should be moved to a cooler, shaded place and given water or sport drinks. More severe symptoms such as diminished judgment, disorientation, pale and clammy skin, a rapid and weak pulse, and/or fast and shallow breathing may indicate heat exhaustion or impending heat stroke and requires immediate medical attention. breathing may indicate heat exhaustion or impending heat stroke and requires immediate medical attention.

Several tips for beating the heat include: -Wear light, loose-fitting, light-colored clothing.
-Drink water or electrolyte-replacing sports drinks often (do not wait until you are thirsty), and avoid drinking sweetened drinks, caffeine, and alcohol.
-Offer help to those in your neighborhood with limited access to air conditioning and transportation, such as seniors or those who are ill. Check on them frequently or take them to a location with air conditioning.
-During peak heat hours stay in an air-conditioned area. If you don't have access to air conditioning in your home, visit public facilities such as shopping malls, parks, and libraries to stay cool.
-Avoid unnecessary exertion, such as vigorous exercise during peak sun hours, if you are outside or in a non-air conditioned building.
-Stay out of the sun if you do not need to be in it. When in the sun, wear a hat, preferably with a wide brim, and loose-fitting, light-colored clothing with long sleeves and pants to protect yourself from sun damage. And remember sun screen and sun glasses.
