Southern California Heatwave Pushed Further Inland As Upper Lows Continue Abnormal Pattern


Not often does a switch happen in a long-range forecast, but I will be pushing the summer heat further inland and out of the metro zones for Father’s Day Weekend and canceling the posts on such any further as the final outlook for that weekend due to a pattern change.

An unusual weather pattern for June is continuing to bring colder than normal summer temperatures.  While so far this is in line with my summer forecast for cooler temperatures it still is unusual to see.

This is all happening due to a ridge of high pressure that is building in from Mexico.  It was building in rather fast and the ridge axis would move over Southern California by the 17th.  However, an upper-level low will drop down as it builds and block the axis from moving over, thus making Father’s Day Weekend a comfortable weekend, but not one where you break out the pool toys or go to the beach.

While the upcoming weekend will have temperatures that of spring, we will see a 20 degree jump from what they have been this month, which has been in the low to mid 60s in the metros lately.  The heatwave with over 100-degree temperatures and mid 90s will be in the deserts, with rogue zones like Kern Valley having mid 90s.

As long as these upper systems continue to drop into the region, summer heat will not start.  As stated before, June, July, and August on average together will have below normal temperatures.  Meteorological Summer started on June 1st and if we end this month without a major summer heatwave, June 2023 will be below average and 1/3 of the summer forecast would be coming true.
