Forecaster: Henz, D.

We’re in the midst of our first Monsoon break period since active weather began the second week of July. As mentioned yesterday, the Monsoon ridge has settled across NM/TX border promoting drier southwesterly flow through much of the atmosphere. Along with the drier air and lack of storm activity, comes warming temperatures. Daily highs will jump back well into the 100s today and Thursday before an uptick in moisture and t-storm chances return. Latest model guidance, shows an uptick in storm activity across the eastern third of the state tomorrow, which may also send outflow winds into portions of the Valley during the evening. Better storm chances begin as early as Friday morning and should continue to ramp up into the upcoming weekend.

For today plan on mainly sunny skies across the region. Daytime temperatures will easily climb into the 104˚F-106˚F range around the Valley. Southwesterly winds will generally remain in the light category with no gusts of any consequence. No storm activity across the County today. Overnight lows will fall into the mid 80s around the Valley under mostly clear skies.

For tomorrow plan another healthy dosing of sun as afternoon highs reach the 105˚F-108˚F range around the Valley. Light and variable winds may give way to localized gustier conditions from any outflow boundaries moving into the Valley. Storm activity looks to remain across the high terrain of central and eastern AZ. Though a large uptick in cloud cover and moisture is expected during the overnight hours into Friday morning even some rain showers for the Friday morning commute. Storm chances will continue to ramp up on Friday and Saturday with the help of easterly steering flow and possibly the passage of an easterly wave. Will have more details on this tomorrow.
