Record high temperatures are likely Thursday during what is expected to be the hottest day of the year so far in Southern California, where several wildfires broke out amid windy and dry conditions.
The region will swelter through another record-breaking day in the midst of a spring heat wave that brought red flag fire weather warnings during dry and windy conditions. Several brush fires broke out Wednesday, including destructive fires north of San Diego.
More than a dozen cities broke or tied high temperatures Wednesday for May 14. The high temperature reached 99 in downtown Los Angeles, breaking the old record of 96 set 124 years ago. Airports in Long Beach and Camarillo topped 100 degrees -- the warmest since 1981.

Thursday's winds will be somewhat weaker than earlier this week but gusts of between 25 and 35 miles per hour are forecast for the morning across the valleys and mountains, according to the National Weather Service. The region has been swept by Santa Ana winds since Sunday, but a gradual transition to onshore winds is expected through Thursday afternoon, the National Weather Service reported.
By Sunday, temperatures are expected to drop toward normal for this time of year.
"Change is on the way," said NBC4 meteorologist Crystal Egger. "Temperatures will be slowly cooling for the weekend."
