Heat wave continues

SAN DIEGO - Already sweltering temperatures across much of San Diego County are expected to push a few degrees upward today toward their eventual peak at the end of the workweek.

On Wednesday, low thermometer readings of 71 degrees in Chula Vista, Escondido and at Oceanside Harbor topped by one degree previous records, set in 1981, 2011 and 1984, respectively, according to the National Weather Service. A low of 69 degrees in Vista equaled the previous Aug. 26 minimum temperature milestone, set in 1988.

Forecasters said high pressure aloft will keep inland areas hot through Friday.
