Synopsis:
Yesterday’s forecast remains on track for today through the upcoming weekend with continuing excessive heat and drying conditions. Looking at the big picture, the monsoon ridge will continue to weaken and dip south/southeast into Mexico over the coming days. This will begin to limit daily storm/rain chances to only the higher terrain areas of eastern and southern AZ as drier air begins to filter in across the state. We’re going to be chasing daily temperature records again today and possibly tomorrow before daily high temperatures should start to see a modest downward trend into next week. For the time being, make sure to keep taking precautions in order to avoid heat related illness. 

For today plan on mostly sunny skies with continuing hazy conditions due to smoke. Afternoon temperatures will quickly warm into the 115˚F-117˚F range around the Valley (Record high of 115˚F, set in 2015). Variable winds will generally hover in the 5-10mph range with localized gusts in 15-20mph range into this afternoon/evening. Any storm activity later today should remain confined to the higher terrain areas north and east of the Valley.

For tomorrow plan on sunny skies and clearer conditions with less smoke being blown across the Valley. Daytime highs should climb into the 113˚F-116˚F range across the lower deserts. Variable winds will be breezy in the 7-15mph range with localized afternoon gusts reaching 25mph. Any storm activity later in the day should again be confined to the higher terrain areas north and east of the Valley. Drier air will continue to filter into the state on Sunday limiting storm chances and also potentially clearing out most of the smoke to the east. Highs will still climb to around the 114˚F mark, and we’ll see another round of breezy conditions with afternoon gusts reaching 20-25mph.
