Temperatures In The 80s: La Mesa Weekend Weather Forecast

LA MESA, CA – A record-setting heat wave that has caused San Diego County to swelter is expected to continue Thursday and persist through Friday night.

The period of extended hot weather, which began Monday and reached its peak Wednesday, could push temperatures into the low 80s near the coast, mid 90s in the inland valleys and mountains, and up to the high 110s in the local deserts, according to the National Weather Service.

Though the peak of the heat wave was expected to be over, an NWS excessive-heat warning will remain in effect in the county through Friday at 9 p.m. The heat wave was originally expected to break Thursday night.
The warning lasts through Friday at midnight for the county deserts.

Although the strong high-pressure system is expected to weaken slightly over the weekend, temperatures will remain above average for this time of year, except near the beaches and at the highest local mountain areas, forecasters said.
