Los Angeles Breaks a Temperature Record

Just how hot was it?

It was 98 degrees Thursday in Chatsworth. It was 96 in Northridge. It was 99 in Woodland Hills. And expect more Valley temperatures in the upper-80s and 90s Friday.

The mercury in downtown Los Angeles hit 92 Thursday, ending a 279-day streak of below 90-degree temperatures.

The last time the temperature reached 90 in downtown was on Oct. 13 when the high was 98, according to the National Weather Service.

The 279-day streak between 90-degree days was the 10th longest since records began being kept in 1877. The longest streak was 358 days from Sept. 17, 1877 to Sept. 9, 1878.

A record high for this date of 86 degrees was set at Los Angeles International Airport, breaking the previous record of 84 set in 1951.

Other highs in Los Angeles County included 99 in Palmdale and Lancaster, 97 in Acton, Saugus and Van Nuys, 96 in Pasadena and Pomona, 93 in Burbank, and 92 at the Long Beach Airport and San Gabriel.

The high temperatures are the results of an offshore gradient in the morning and only weak onshore gradients in the afternoon, combined with a warm airmass left over from the passage of the remnants of Hurricane Fabio, according to the National Weather Service.

Highs of near 85 are forecast for Friday in downtown Los Angeles, near 81 in Long Beach, the lower-to-mid-70s at the beaches, the upper-80s and 90s in the San Fernando Valley, the upper-80s to mid-90s in the San Gabriel Valley, the 90s in the Santa Clarita Valley and upper-80s and 90s in the Antelope Valley.
