Tuesday’s Tucson Forecast: Brief downturn in storm development




Today – 20% chance of storms. 97°, southwest wind 5-10 MPH.

Tonight – Mostly clear late. 73°, southeast wind 5-10 MPH.

Tomorrow – 30% chance of storms. 94°, south-southwest wind 10 MPH.



After a loud & wet overnight, storms a little more miss than hit later this afternoon.

A worked over atmosphere likely limits storm development to the isolated variety. Tucson stands a 20% chance of storms between 2-9 PM, while areas south & east have a 30% chance. Daytime highs reach the mid to upper 90s metro-wide, with low 70s for overnight lows.

Today’s Monsoon Prediction Index is 2 out of 10 for Tucson, indicating a low storm risk.

Monsoon moisture increases tomorrow and Thursday, leading to a better chance of scattered thunderstorms. Thursday could be the most active day of the week, with rain chances at 40% during the afternoon and early evening hours.

Uncertainty remains with the Labor Day weekend forecast. Most models shows tropical moisture from what will likely become Tropical Storm Kevin staying south of Arizona. There is a 20% chance of storms Friday through Monday, but those rain chances may increase if some of Kevin’s moisture advances further north than anticipated.


Love both of these shots & for different reasons. Yours truly is a sucker for A) the soft sunset glow on the Catalinas during a storm and B) lightning shots with downtown Tucson in the foreground. Job well done by Nicole Tilicki in Oro Valley & Sean Parker in Tucson. It’s a tie for “Sky Candy of the Day”!
