Yesterday’s forecast remains on track for a mid-week warming trend. Looking at the big picture, high pressure will develop across the Desert Southwest today into Thursday lending to a return to mid to upper 80s across the lower deserts. Quiet conditions will be short-lived though as another weather system will move out of the Great Basin and into AZ Friday lasting into Saturday. Expect another dramatic cool-down on Friday with highs falling back into the upper 60s to low 70s to go along with breezy/windy conditions and an outside shot at some light showers through the period.
For today plan on a healthy dosing of sun under clear skies. Daytime temperatures will rebound into the 84˚F-86˚F range around the Valley with higher terrain areas reaching the upper 70s to low 80s. Variable winds will generally remain in the 2-7mph range with localized afternoon/evening gusts around 10-15mph. Overnight low temperatures will dip into the upper 50s around the urban corridor under clear skies.
Tomorrow looks to be the warmest day of the week with daytime highs peaking in the 86˚F-89˚F range around the Valley. Plan on mostly sunny skies mixed with some passing cirrus clouds. Breezy conditions will begin in the afternoon hours in the 7-14mph range with gusts approaching 20-25mph through the overnight hours. A dry cold front will move across the region early on Friday bringing a dramatic drop in temperatures and continuing breezy/windy conditions. Highs will fall back into the upper 60s to low 70s. A few higher terrain showers will be possible beginning Friday and continuing on Saturday as the bulk of the system moves through. More details on this in tomorrow’s extended Outlook.
