You can probably put your umbrella away for a while!
Monday – Tuesday: There will be a chance of showers / thunderstorms, though most of the activity will be north of the Mogollon Rim. Some isolated severe storms are possible across the state. Storms that form will be capable of hail up to 1” diameter and gusty winds. Storms will generally propagate towards the northeast at 10-15 mph. Highs in the upper 70s to lower 80s. Lows in the upper 50s.
Wednesday – Sunday: Mostly sunny with light wind. Precipitation unlikely, except perhaps late in the day on Sunday. Highs in the low to mid 80s. Lows in the mid to upper 50s.

Hurricane Kay no longer exists, but the leftover moist air from the storm streamed across Arizona last weekend as the storm dissipated off the west coast of the Baja of California. This led to showers and thunderstorms around the state on Friday – Saturday. Then, late yesterday, a weak trough of low pressure left over from Kay began to drift northeastward across the state. This produced an area of cooler air and enhanced lifting and shearing that generated a line of thunderstorms moving northward across the Prescott area overnight. Rainfall totals this morning ranged from 0.25” to 0.75” across the area from last night’s fast-moving convective system and trailing stratiform rain.
Today and tomorrow, the atmosphere remains very moist, and with ample solar heating we will see scattered thunderstorms in the afternoon and evening each day, especially north of the Mogollon Rim. The Storm Prediction Center (www.spc.noaa.gov) is indicating a marginal “MRGL” chance of severe thunderstorms with possibly large hail and damaging wind gusts over much of Arizona today.
By Wednesday, westerly winds will bring drier air across the state and the air will gradually dry out. Skies will become mostly clear. There is some indication in the long-range forecast models that additional tropical moisture could move across Arizona next Monday – Tuesday as low pressure develops along the California coast and ushers southerly winds across the state. However, for now, it appears Wednesday – Sunday will be mostly sunny.
