Southern California could see more record-setting temperatures Friday as a heat wave continues across the region. But relief may be in sight, forecasters said, with a slight cooling trend expected Sunday or Monday.

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%.

Lancaster and Woodland Hills, which topped out at a record-breaking 109 degrees Thursday, could see more of the same Friday.

The National Weather Service predicts highs in the upper 90s to near 110 across the western San Fernando Valley, 90s to about 102 in the San Gabriel Valley, the lower 90s near downtown Los Angeles.

“We’ll see a little more moisture and maybe some cloudiness by Saturday, but it may not be very noticeable,” said Todd Hall, National Weather Service meteorologist. “Sunday and Monday, we’ll get more of a real break,” when temperatures dip a few notches and winds shift to the southeast.

Even with the hot temperatures, Californians were being urged to reduce power consumption, especially during the hottest hours, to maintain power supplies and lower the risk of outages.

A "flex-alert" has been issued through Sunday by the California Independent System Operator, which manages most of the state's power grid.
