Forecaster: Henz, D.
Yesterday’s forecast remains on track for the next few days with continuing above average temperatures and a low grade monsoon pattern in place for the remainder of the season. Looking at the big picture, high pressure over AZ continues to weaken and will begin shifting east into TX over the coming days. A modest moisture surge last night helped kick off a few storms which brought some localized downpours to parts of the Valley. We likely don’t see nearly as much activity today/tonight, but storm chances will resume on Wednesday (possible AM activity) and continue through Friday. Otherwise, high temperatures across the lower deserts will remain quite warm in the near term hovering around the 104˚F mark.
For today plan on sunny skies and hot conditions across the region. Afternoon temperatures will quickly warm into the 101˚F-104˚F range around the Valley. East winds will be breezy at times in the 7-14mph range with localized gusts around 20mph into the evening hours. Storm chances are expected to remain rather limited this afternoon/evening with most activity across southern AZ and the higher terrain up north. Our southwest zones could see some isolated activity later tonight and perhaps again tomorrow morning.
For tomorrow plan on a quiet start to the day around the Valley with perhaps some morning shower/storm activity across southwestern AZ. Daytime highs will climb into the 101˚F-103˚F range around the Valley. Variable winds will hover in the 5-10mph range with localized gustier conditions near any storm activity. Better storm chances will return tomorrow afternoon/evening with help of a passing disturbance to our south. Storms should initiate across southern AZ with activity trying to push north/northwest into portions of the County including the greater Phoenix Valley. Stronger storms will be capable of brief heavy downpours, gusty winds, and blowing dust. Temperatures will continue to slowly trend down as we move into Thursday and Friday. As mentioned above, modest storm chances will also linger through the end of the work week.
