Upper level high pressure as exerted hotter weather into California as the "yo-yo low" from this past weekend meanders back to the west across northern Mexico. Our temperatures are forecast to heat up for the next several days to the mid 90s. A few spots in the south valley could get close to 100° for Saturday. This unseasonably hot weather has prompted the issuance of Heat Advisories in the Los Angeles area for the next few days. South valley highs will remain in the mid 90s all the way through next Tuesday.
The low pressure system will maneuver to a position southwest of Baja by this weekend. It is pushing a bit farther west than earlier estimates and will result in a lower probability of rainfall for southern California and Kern County. But there is still plenty of uncertainty with this feature. The American model is bringing the system through on Thursday with a chance for showers. So I've kept a 10% probability for Wednesday and Thursday in the forecast. Temperatures will drop a bit into the 80s for highs by Thursday.
At this point no heavy rainfall is expected with next week's system. The big news will be our lingering heat with daytime readings in the south valley running 10 to 15 degrees above normal for mid October.
