Heat continues to dominate our weather headlines, but Friday’s also bringing slightly elevated storm chances back into the conversation especially after a pop up monsoon storm brought some showers to parts of the Las Vegas Valley yesterday.
We were forecasting an official high of 109 yesterday, but Mother Nature decided to blow that out of the water with a high of 112, which is our hottest temperature of the year… so far, since we’ll likely eclipse that mark at least once this weekend.
We were also forecasting a dry day for the Las Vegas Valley, with the bulk of the shower activity expected to develop to the north and east of us, but we saw a stray shower develop around the Chinatown area after 7 p.m. last night and move northwest before dissipating through Skye Canyon.
No rainfall was recorded officially at the airport, but the shower did make for a nice show, which we featured this morning on Good Morning Las Vegas, thanks to some viewer photos.

What happened yesterday is emblematic of monsoon season: if the conditions are there (increased humidity, daytime heating that generates convection), a stray storm with a very small coverage area can develop, even if it doesn’t seem likely in the forecast.
It’ll be a very similar set up today, with increased chances for pop up storms to develop after the 11 a.m. hour and through this afternoon and evening, but again, coverage isn’t anticipated to be widespread across the Valley.
We’re going for 111 for our official high temp on Friday, 112 with a lingering 10% chance of storms Saturday and 113 on Sunday, as our Extreme Heat Warning continues through Monday evening, thanks to these above normal high temps and exceptionally warm overnight lows that aren’t giving us much relief from the heat.
Stay cool this weekend, and take this heat seriously!
