The heat may have peaked, but the HEAT WARNING has still been extended. Temperatures were well into the triple digits on Wednesday. Escondido hit 112 degrees, making it the hottest place in the county, including the desert. The high of 112 shatters the old record for this date of 104. Wednesday was tied for Escondido’s second hottest day ever, dating all the way back to 1893.
Wednesday was the 4th consecutive day of 93 degree or warmer weather at San Diego’s Airport. That’s the first time we’ve had four consecutive 93+ degree days in more than a decade (October 2015) And it’s only the 6th time ever we’ve had four or more consecutive 93+ degree days at the airport. The record is 6 straight in 1939. Through the first nine days of the month, this year is tied for the fourth hottest start ever for San Diego.
The HEAT WARNING for the coast and valleys will now stay in effect through Thursday evening. While Thursday is still going to be very warm, we can expect temperatures to slowly start cooling tomorrow and continue trending down into early next week.
Showers are still possible over the mountains each afternoon, but chances will drop as the week goes on.
The weekend will continue to cool. We should also see more morning marine layer clouds, and cooler overnight temperatures. The more seasonal temps continue into next week.
