Synopsis: Yesterday’s forecast remains on track for today through the end of the work week with a break period to the monsoon and strong upcoming warming trend. Looking at the big picture high pressure, currently centered over the lower Great Plains, will build back west into the Desert Southwest by Friday. In the near term, southwesterly upper-level flow will keep conditions dry and high temperatures near seasonal averages. Moving ahead the ridge will settle somewhere near the Four Corners region into this weekend and daily temperatures will see a boost towards 110˚F region. Despite the heat, the new ridge placement late week may also allow for a return to modest storm chances to southcentral AZ.
For today plan on mainly sunny skies across the region. Afternoon temperatures will warm into the 103˚F-106˚F range around the Valley. Variable winds will generally hover in the 5-10mph range with localized greater gusts around 15mph this afternoon/evening. No storm activity is expected around the region. Overnight lows will dip into the low 80s around the urban corridor under mostly clear skies.
For tomorrow plan on a near repeat of today with plenty of sun across the region. Daytime highs will climb into the 105˚F-108˚F range around the Valley. Variable winds will remain in the light category with localized afternoon/evening gusts around 10-15mph. No storm activity is expected around the County. The warming trend will kick into high gear on Friday with temperatures likely reaching the 110˚F mark followed by even warmer readings on Saturday and Sunday. We’ll keep a close eye on where the ridge eventually sets up as this will give us a better idea on temperatures and storm chances this weekend. Stay tuned!
