TUCSON - At long last, signs of Monsoon life are set to appear this week in portions of southern Arizona.
According to News 4 Meteorologist Jeff Beamish, high pressure over El Paso will expand and move near the Texas/Oklahoma border by the middle of this week. This shifts winds aloft from the southwest to the south, drawing in Monsoon moisture.
Enough moisture will be in place to develop isolated thunderstorms starting Wednesday in the higher terrain of Cochise, Graham and Greenlee Counties. At this point, these storms will lack the upper air support needed to push off the mountains and into valley floors.
A few of these thunderstorms may also produce dry lightning, elevating the wildfire danger east of the Tucson metro.
