Gusty winds develop, extreme heat arrives late weekPosted: Updated:
PHOENIX -- Crews battling the Doce fire will be hit with another round of strong winds heading into Monday. Meanwhile, the Valley of the Sun is on par to get a true taste of summer later this week.
A trough of low pressure moving through the Pacific Northwest will be the trigger for gusts of up to 40 miles per hour along Northern Arizona. Southwest winds should be sustained at around 15 to 25 miles per hour. Relative humidity will also be low, so the National Weather Service issued Red Flag Warnings for the Mogollon Rim, the White Mountains north and the Yavapai County mountains starting at 10 a.m. Monday and expiring at 8 p.m.
Temperatures across the Valley Monday and Tuesday afternoon will be the lowest of the week, topping out around 105 degrees. On Wednesday, a heat wave begins to take shape as a strong ridge of high pressure builds over the Four Corners region. By Wednesday, most Valley communities will see temperatures around 110 degrees. From Thursday through Sunday, temperatures Valleywide will range from 113 to 117 degrees. The National Weather Service may issue Extreme Heat Warnings during this time.
Next weekend, our forecasting models indicate a tropical system developing near Northern Mexico. This could send some moisture in our direction from the east, which is one of the ingredients that we’ve so far been lacking from our monsoon season.
