Brace for a heat wave in one week?
After July 4th we will see a major increase in temperatures as one of the largest heat-domes (ridge of high pressure) develops directly in the center of the country. We will be on the southwestern edge of this clockwise flowing ridge of high pressure. This.. with major hurricanes to the south expected.. will create inverted troughs through the Southwestern United States, kicking off monsoon season with a bang with showers and thunderstorms all the way through metro Southern California by end this next week into next weekend..
If you have plans to go to Disneyland, Knotts, Magic Mountain, or Universal Studios.. change them. This type of heat in the basins is deadly. In addition to the heat, we will have unbearable humidity. So.. you have your warning from me.. in fact you’ve had it for well over a week or more now if you remain following me at Southern California Weather Force.
The reason we are hotter in the IE more-so than Palm Springs is the east/southeast flow right off the mountains, similar to an offshore wind (Santa Ana Pattern), however this will be a humid and hot even as shower/tstorm activity develops and moves through the area, utilizing the energy in the atmosphere (hot air rises) from those temps.
Catalina Island will be at 90F with humidity so this will be feel a lot like Hawaiian there so if you fancy a Hawaiian Vacation, hit that Island this next weekend (after the 6th) but take precautions hiking anywhere (not recommended)
Keep those pets, elderly, and you safe and I will report with additional warnings soon. The image above is my projected high temperatures by Friday or this next weekend (A week from now) …
