PHOENIX – The Valley heads into the final weekend of summer and last stretch of the annual monsoon season with uncertainty in the short-term weather forecast.
Monday is the first day of fall, and Sept. 30 is the end of Arizona’s “rainy” season.
Isolated showers popped up throughout the day Friday in the wake of storms that developed the previous night and caused some flash flooding.
“As we head into later today, any sort of activity is expected to be mostly concentrated north and east of Phoenix toward the higher terrain areas, but we cannot rule out a few isolated showers and storms affecting portions of the Phoenix area later this afternoon into early this evening,” Gabriel Lojero, a meteorologist with the National Weather Service (NWS), told KTAR News 92.3 FM on Friday morning.
Is there any rain in weekend Phoenix forecast?
Looking ahead, Saturday’s forecast calls for sunny skies and a high in the upper 90s, about normal for this time of year.
“We’re still going to be seeing some humid conditions,” Lojero said. “The good news is that our temperatures are actually going to stay near to slightly below 100 temperatures for high temperatures, probably into early next week.”
Meanwhile, meteorologists are tracking another disturbance that could bring more rain to the Valley before the weekend ends — but the outlook is uncertain.
“We may see another shot of rain starting late Sunday and maybe it may extend into early next week,” Lojero said. “We have to wait and see how that forecast pans out.”
Phoenix adds to monsoon season rainfall total
Despite the recent precipitation, Phoenix is closing on its third consecutive monsoon season with under 1 inch of total rainfall.
A combined 0.23 inches fell late Thursday and early Friday at Phoenix Sky Harbor International Airport, which the NWS uses for the city’s official readings.
That increased the city’s monsoon season total to 0.91 inches, well behind he normal amount to this point of over 2.2 inches.
Unless the airport gets at least 0.09 more inches before the end of the month, 2025 will go down as Phoenix’s 14th driest monsoon on record.
