Arizona – A biting, below-freezing start is gripping Flagstaff this morning, with temperatures near 27 degrees, but a rapid warmup and shifting spring pattern will bring storm chances and strong winds into the picture within the next 48 hours.
According to the National Weather Service, calm and clear conditions early will give way to highs near 69 degrees by this afternoon, with light winds increasing slightly later in the day. That sharp temperature swing sets the stage for instability heading into Monday.
By Monday afternoon, a 20 percent chance of showers and thunderstorms develops after 11 a.m., especially along corridors near I-40. While coverage remains isolated, brief downpours and lightning could create sudden travel slowdowns. Drivers should stay alert for changing road conditions.
Tuesday brings a return to dry air and sunshine, with highs near 68 degrees, but winds begin to ramp up. Gusts could reach 31 mph by afternoon, especially across open terrain and higher elevations. Loose objects may shift, and high-profile vehicles could feel crosswinds.
By Wednesday, winds strengthen further. Southwest gusts up to 39 mph are expected, with temperatures cooling to around 61 degrees. Blowing dust is possible in exposed areas, and visibility could drop at times along open highways.
Cool nights remain a concern. Temperatures dip into the 30s, raising the risk of localized “flash freezing” on elevated surfaces if any moisture lingers.
Plan ahead—secure outdoor items, stay weather-aware during Monday’s storm window, and prepare for gusty midweek travel.
