Heat Wave

A short heat wave this week could push temperatures above 100 degrees by Thursday in the valleys surrounding Glendale and Pasadena, according to the National Weather Service. Even today, daytime highs could hit the mid-90s as a high pressure system builds over the region, the weather service said. On Wednesday, expect highs of 100 degrees in the Burbank-Glendale area, and up to 102 on Thursday, Conditions should be slightly cooler in the Pasadena region, with daytime highs not expected to get past the high-90s, according to the weather service.

Red flag warnings were issued Wednesday across Southern California as heat and dry winds were expected to turn Los Angeles and Ventura County mountains and valleys into a tinderbox. The National Weather Service said the red flag warnings would be in effect through Thursday for the mountains of Los Angeles and Ventura counties, the Santa Monica Mountains, the San Fernando and Santa Clarita valleys and Ventura County valleys, the L.A. Times reported. Temperatures on Friday could rise past 100 degrees from Burbank to Pasadena, according to the weather service.

State forest firefighters will be on alert for brush fires in coming days as temperatures rise and strong winds prevail in Southern California. The Inland Empire already was experiencing high winds and rising temperatures early Wednesday, said Daniel Berlant, a spokesman for the state Department of Forestry and Fire Protection, commonly known as CalFire. Winds were picking up Wednesday “to allow for the possibility of a mild Santa Ana event,” Berlant said. “This puts us back into the peak of fire season down in Southern California.” After rain earlier this month, forecasts call for temperatures in the 90s Wednesday and Thursday, and in the high 80s and low 90s Friday.

With temperatures expected soar into the 90s this week, two cooling centers have opened in Glendale to provide seniors a place to stay out of the heat. The Adult Recreation Center, 201 E. Colorado St., will operate its cooling center 8 a.m. to 6 p.m. Monday to Thursday; and 8 a.m. to 4 p.m. Friday and Saturday. The cooling center at Sparr Heights Community Center, 1613 Glencoe Way, will run from 8 a.m. to 5 p.m. Monday and Tuesday; 8 a.m. to 6 p.m. Wednesday and Thursday; and 8 a.m. to 3 p.m. on Friday.

A combination of high pressure and offshore winds should send temperatures soaring later this week, according to the National Weather Service. After hitting the upper 70s on Wednesday, highs in downtown Los Angeles are expected to be well into the 80s for the rest of the week, according to Stuart Seto of the National Weather Service. Seto said the peak will likely come on Friday, which should see a high of 89 degrees downtown. In the Burbank-Glendale-Pasadena region, temperatures are expected to following a similar trajectory, possibly hitting 90 degrees on Saturday, according to the weather service.

More triple-digit temperatures are expected Wednesday as a ridge of high pressure settles in over Southern California and the area continues to swelter. The heat wave is expected to last through Saturday, with the highest temperatures likely from Thursday on. But the differences between Wednesday and the rest of the week may be slight. “It may be hotter later in the week but you're not really going to be able to tell,” National Weather Service meterologist Rich Thompson said.

You know it's hot when hitting 90 degrees is considered a cooling trend, but that's what region has to look forward to Sunday evening, when a week of triple-degree heat is expected to start subsiding. For now, the National Weather Service has issued excessive heat warnings through 8 p.m. Friday night, because of the combination of high temperatures and relatively high humidity for the Southland -- 20% to 30%. In the Burbank-Glendale region, temperatures could hit 105 on Friday, and then 102 degrees on Saturday, according to the National Weather Service.

Mark Humphrey The signs of a heat wave were palpable on Thursday afternoon, as people walked the streets covering their heads with newspapers, fanning themselves and ducking indoors to air-conditioned businesses to avoid the scorching weather. "I really hate the summer heat," said Sumit Shivnani, a cashier at Quizno's in the Glendale Marketplace. "But what can I say? Summer is summer." Thursday tied a record high for the date of July 21 at 96 degrees, but wasn't even close to the month of July's overall record of 106 degrees, set in 1988, according to Glendale-area climatologist Bob Gregg.

GLENDALE — A heat wave creeping into the Southland boosted Glendale’s temperature into triple digits Thursday after tying a record high Wednesday, and meteorologists say there is little sign of cooling until the middle of next week. A high-pressure system hovering over Arizona is heading north and cooking Southern California, prompting state health officials and local utilities to issue heat advisories this week as triple-digit temperatures blanket the area. “This large area of high pressure, which is pretty typical in the summertime, doesn’t like to move very quickly, so we’re looking at a heat wave that started [Wednesday]

Glendale residents waited and waited, but they never felt the severe heat that the National Weather Service warned about this week. A heat-wave advisory issued by the weather service for California mountain ranges, where record-high temperatures and low humidity have been reported, was set to conclude by Thursday night, according to the California Department of Forestry and Fire Protection. There is a heat wave — just not in Glendale, said Stuart Seto, weather specialist at the Los Angeles Forecast Office.

Public health officials today warned that the air quality in the Santa Clarita and east San Gabriel valleys is unhealthy, and those with respiratory ailments should limit outdoor activity.

Burbank and Pasadena are expected to remain in the 90-degree range throughout the week The air quality warning applies to people with heart disease, asthma or other chronic respiratory diseases.
