THE EXTREME HEAT CONTINUES....

The month of August is opening up with more relentless heat. It is summer, and hot weather is no stranger to the desert. However, this summer has been one for the record books.

Storm clouds from earlier July when 1.11 inch of rain fell in Palm Springs.

Storm clouds from earlier July when 1.11 inch of rain fell in Palm Springs.

To put this heat into perspective, here are a few interesting facts:

  • Average High temp at Palm Springs Airport: 109.8 degrees
  • Average Low Temp at Palm Springs Airport: 85 degrees
  • Average OVERALL temp for July, 2018: 97.4 degrees.

Palm Springs experienced 14 days over 110 degrees in July, with 9 of those days over 115! There were 5 nights where the low temperature was 90 degrees or higher!

The average high/low for Palm Springs in July is about 108/78. Sad to say, but most of us would dream for a comfortable 78 degrees some morning soon! Look at the toasty temps the past 5 days as well!

  • 8/3: 116/88
  • 8/2: 114/90
  • 8/1: 113/88
  • 7/31: 110/92
  • 7/30: 114/89

UPCOMING OUTLOOK IS VERY HOT WITH INCREASING HUMIDITY AGAIN....

For those hoping for some cooler weather, your hopes will be dashed the next few days. A massive high pressure system will be strengthening over our area through Tuesday. This will only tend to increase our heat by a few degrees the next few days. The only good news is that the humidity levels have dropped and dew points have retreated back into the 40s and 50s. This dry airmass should last until Tuesday or so. It's possible the nighttime lows may finally drop below 90 degrees as the lower humidity allows slightly better radiational cooling each night. We're really splitting hairs at this point though!

Sorry for the bad news.....

  • Monday: 117/88
  • Tuesday: 116/88

POTENTIAL HUMIDITY INCREASES AGAIN AFTER WEDNESDAY....

As the high pressure system over the desert Southwest weekend just a tad, and moves to the north by Tuesday night and Wednesday, the upper level winds will switch back to the southeast and east. This will allow the transport of moisture back into our area. This will support daily thunderstorms across Arizona and Northwest Mexico, which will increase the likelihood of gulf surges and thunderstorm outflows to increase humidity once again. It is quite possible we will experience humid and hazy conditions and southeast winds by Wednesday morning, with dew points over 65-70 degrees again. Afternoons may dry slightly, with more humid conditions returning in the late night and morning hours through the end of the week. The intensity of the humidity will be dependent upon exactly where the storms to our southeast set up, which is impossible to predict at this point.

Temperatures will likely cool a few degrees, as humid air is not as conducive for temps much above 115. Therefore, we may see high temps fall back into the 107-112 range for Wednesday, Thursday and Friday. Any organized storms could even drop those temps further - but this isn't highly likely. The best chance of afternoon and nighttime thunderstorms during this time period will be in the nearby mountains, as well as the Joshua Tree/Yucca area. Perhaps we will get lucky and score some rainfall. Too early to tell.

HURRICANES OFF MEXICO NEXT WEEK?

Long range forecasts are predicting a series of hurricanes to potentially develop off Mexico next week. At this time, they aren't expected to hit Southern California, and instead will curve out to sea off Baja. However, the circulation around the backside of these systems could only serve to strengthen the southeasterly wind flow, and potentially solidify the transport of humidity our way.  It will be interesting to see if the computer weather models change their tune, as a shift more north could support dramatically cloudier or wetter weather for Southern California. 

SEA TEMPS ARE TOASTY!

Just to our west, the water temperatures off the coast of San Diego have risen to a record breaking 77-79 degrees last week! This is far above the normal 68-71 degrees more typical for this time of year. Anyone traveling to the coast has likely felt the muggier conditions that are a result of these abnormally high water temps. Take a look at the imagery via this National Weather Service tweet, from a few days ago!

So, the screaming message this week is STAY COOL, and HYDRATE! Let's hope we get some moisture later this week! Enjoy the lack of humidity Monday and Tuesday while it lasts!
