Lots to talk about in today’s extended Outlook with a general cooling trend on tap for this weekend and into next week. For today, the back side of the departing ridge combined with warm air advection will yield a final round of mid to upper 80s across the lower deserts even despite increasing cloud cover and breezy conditions. A weak disturbance will then move east across the region overnight into early Friday bringing some light showers along with a weak cold front. Little if any measurable rain is expected across the lower deserts (virga and sprinkles) with higher terrain areas maybe seeing up to 0.10”. Sunnier conditions will return tomorrow into Saturday with highs stepping back into the upper 70s to around 80˚F before a follow up system arrives on Sunday knocking highs back into the low 70s.

For today plan on cloudier overcast skies especially into the afternoon/evening. Afternoon temperatures should still warm into the 86˚F-89˚F range around the Valley with low to mid 80s across the higher terrain locales. South/southwest winds will be breezy at times in the 7-14mph range with gusts around 20-25mph possible. Overnight lows will remain mild only falling into the mid to low 60s under cloudy skies mixed with light showers. Tonight/overnight rain chances are covered in Table 1 below.

For tomorrow plan on a return to mostly sunny skies across the region. Daytime highs will step back into the 78˚F-81˚F range around the Valley. West/southwest winds will hover in the 3-8mph range with localized gusts around 15mph. Plan for similar conditions again on Saturday with highs in the upper 70s. Additional cooling arrives on Sunday as a dry cold front moves across the region with another round of breezy conditions. Afternoon highs are forecast to dip into the low 70s and the colder air mass will remain in place into early next week.
