Synopsis: Lots to discuss in today’s forecast with a brief Monsoon pulse followed by another very hot weekend in store. High pressure to our east will continue to allow a surge of moisture north into AZ today through Friday resulting in a low grade Monsoon pattern. Scattered storm activity will be possible across southern AZ today with activity then overspreading the higher terrain areas well north and east of the Valley tomorrow. Moving ahead, the ridge will continue to progress west into AZ this weekend and daily highs will see a pronounced jump back towards the 110°F mark for Independence Day into early next week.
For today plan on partly sunny skies mixed with periods of passing clouds. Afternoon temperatures will warm into the 102°F-104°F range around the Valley with muggy conditions as dewpoints surge towards the low 50s. South winds will hover in the 5-10mph range with afternoon/evening gusts in the 15-20mph range. Scattered storms will be possible again across southern AZ and some of this activity will try and move north into the County later this evening/tonight in the form of gusty outflows, dust, and perhaps some sprinkles. Overall, we expect most locales to remain quiet and dry. Otherwise plan on overnight lows in the mid to low 80s around the urban corridor.
For tomorrow morning plan on a return to mainly sunny skies and warming temperatures. Daytime highs will climb into the 104°F-107°F range around the Valley. South winds will generally hover in 5-10mph range with localized greater afternoon/evening gusts. Isolated storm activity will be possible again with the focus across the higher terrain areas north and east of the Valley. Heading into this weekend, the warming trend will kick into high gear as moisture levels retreat and high pressure settles over the region. Daily highs on Saturday and Sunday will climb at or just above the 110°F mark. At this point, we’re not expecting any weather issues for your 4th of July festivities/bbqs other than the heat.
