Forecaster:  Henz, D.
A cutoff disturbance will progress east along the AZ/Mexico border today providing some additional shower/rain chances followed by a quieter/drier period into Friday. This system mostly underperformed across Maricopa County instead focusing the bulk of the rain over SoCal and SW Arizona. For example, Yuma saw nearly a third of its yearly precipitation fall just yesterday! Moving ahead, guidance continues to show two more weather systems set to affect the region with one arriving later Sat into Sun and the second during the Mon/Tues period. Both of these progressive systems should provide better desert rain/mountain snow chances to our region along with much colder temperatures.

For the rest of this morning plan on lingering light showers/rain across portions of the County followed by eventual clearing/pockets of sun into the afternoon/evening. Daytime temperatures will warm into the 67˚F-70˚F range around the Valley. Variable winds will hover in the 3-8mph range with localized gusts in the 10-15mph range. Overnight lows will dip into the mid 50s around the urban corridor under partly cloudy skies and light winds.

For tomorrow plan on partly sunny skies mixed with periods overcast skies. Afternoon highs will climb into the 64˚F-67˚F range around the Valley. Variable winds will remain in the 3-8mph range with no gusts of any consequence. There could be some isolated light showers mainly across the higher terrain areas tomorrow afternoon/evening, though we’re not expecting much in the way of measurable rain. Moving ahead to Saturday, unsettled weather and rain chances will return to most of the region. Temperatures will fall back into the low 60s to go along with breezy conditions. As of now, the best chances for showers/rain look to be Saturday evening into Sunday morning. We’ll have more details on this and the second system arriving early next week in the coming days.
