Yes, it may very well be true! A slightly cooler and drier weather pattern may FINALLY be on its way for a week or so, but not before one more round of humidity tracks into our area from the southeast on Tuesday.
The Palm Springs area will be on the extreme western edge of another southeast push of humidity creeping north from Mexico. Southeast winds are expected to bring elevated humidity levels tonight and Tuesday, with dew points rising back up to or over 70 degrees once again. Cloudiness may accompany the wind shift tonight and Tuesday, with even a very slight chance of a shower or thunderstorm tonight and tomorrow. Hazy skies are likely as well, and even a remote chance of a nighttime haboob if any thunderstorm complexes were to form tonight in the deserts near Yuma, Arizona. The Joshua Tree area has a higher chance of a thunderstorm tomorrow, as has been the case with recent monsoon flow events. The higher terrain helps initiate greater instability and cloud formation I'm that area.
The last bout of humidity and storms brought some much needed rain to the nearby mountains and deserts, as well as some incredible cloud formations and lightning shows.
HOW HOT HAS AUGUST BEEN?
Normal high/low temps right now are 106/78. A look at Palm Springs Airport shows that 79% of the daytime highs have been above average so far this month, and 100% of the nighttime low temps have been above average. This come on the heels of the hottest July on record. Here's how each day stacked up:
- Aug. 19: 114/85
- Aug. 18: 112/85
- Aug. 17: 103/85
- Aug. 16: 102/85
- Aug. 15: 106/82
- Aug. 14: 109/81
- Aug. 13: 110/84
- Aug. 12: 110/86
- Aug. 11: 109/85
- Aug. 10: 108/89
- Aug. 9: 104/88
- Aug. 8: 110/88
- Aug. 7: 111/86
- Aug. 6: 115/80
- Aug. 5: 115/81
- Aug. 4: 116/86
- Aug. 3: 116/86
- Aug. 2: 114/90
- Aug. 1: 113/88
The silver lining, if there is one, is that there has only been 1 night at or above 90 degrees... which is far better than July.
SLIGHTLY COOLER WEATHER ON THE HORIZON
By Wednesday, we expect the upper level air flow to switch from a southeasterly to a southwesterly direction. This tends to be a much drier pattern for our area. The lower level humidity levels will likely begin to diminish slowly starting Wednesday, and continuing though this weekend and into next week. This means dew points will likely drop once again into the 40's and 50's instead of the 60's and 70's... so evaporative coolers may in fact work again for those who appreciate the energy savings! Gusty northwest winds will become common again in the afternoon and evening hours along the I-10 corridor, occasionally lurching south for a few hours into the northern sections of the Coachella Valley communities over the next 7 days. Joshua Tree and Yucca will experience periods of gusty southwest winds as well, with a reduction of 5-8 degrees in temperatures over recent values as well.
As we head into next week, it appears a low pressure system may move into the Pacific Northwest. If this were to occur, even cooler temps are likely next week, with high temps potentially falling BELOW normal for the first time in a long time. It's too far out to predict those temps with certainty yet, but it would be a welcome weather pattern change if it occurs! Here's the current outlook:
- Tuesday: 109/85 (humid, slight chance of t storms)
- Wednesday: 108/82 (clear)
- Thursday: 108/80 (clear, breezy)
- Friday: 106/79 (clear, breezy)
- Saturday: 105/78 (clear, breezy)
- Sunday: 104/77 (clear, breezy)
- Monday: 103/76 (clear, breezy)
- Tuesday: 101/74 (clear, breezy
I can't speak for everyone, but I am ready for the humidity to depart for a bit. It's likely we will get a few more monsoon patterns the first few weeks of September... but climatologically they become more rare after Sept. 15th!
Have a great week! Enjoy the shortening days, as we lose several minutes a day of daylight right now as we head into fall.
