10/8/14 – Chances for showers will increase across northern Arizona today as moisture associated with the remnants of what is now post-tropical cyclone Simon interacts with a trough moving across the state. Areas of heavy rain and localized flooding are possible, mainly south of Interstate 40. A few thunderstorms could also develop but strong thunderstorms are not currently expected.

For Thursday the area of heaviest precipitation is expected to shift eastward roughly along and east of a line from Payson to Window Rock. Thunderstorm coverage is expected to increase on Thursday due to greater instability with the passing trough.
