Temps keep slipping into the weekend

The coast & valleys felt relief from the heat while the desert stayed hot today. Hot highs will hold on for one more day, east of the mtns, before a cooler weekend.

Temperatures will take another hit tomorrow as high pressure continues to weaken and exit east. Behind it, an area of low pressure will close in on the State and trigger a strong onshore flow across Southern California. 

The marine layer will return tonight through tomorrow morning stretching farther inland over the valleys.

FRIDAY MICROCLIMATE HIGHS:

  • Coastal highs near 71°, normal around 69°
  • Inland highs near 78°, normal around 79°
  • Mountain highs near 80°, normal around 72°
  • Desert highs near 104°, normal around 97°

The onshore breeze will knock temperatures back to near seasonal, west of the mountains. On the flip side, temperatures will remain warmer than usual tomorrow for the mountains and desert. 

An Excessive Heat Warning remains in effect for the desert until Friday evening.

By Saturday, cooler air will spread farther east as gusty westerly winds knock temps back into the 70s in the mountains and 90s for the desert. Expect wind gusts up to 35 mph.

Once the low lifts out for the second half of the weekend, temperatures will rebound slightly. It will be a little warmer across the County. The bump up in temps will last through Monday.  

Cooler conditions will return by Tuesday as a trough of low pressure moves in over the West Coast. This will keep the marine layer intact each morning, afternoon sunshine with temperatures on the mild side.
