Synopsis: We got a welcomed treat this morning with a band of showers moving north across Maricopa County bring light rain to most locations. These showers will continue to shift north/west for the next few hours before exiting the region. Overall, the next 5-7 days are still shaping up to be unsettled and wet with multiple disturbances forecast to move across the Desert Southwest. Our main focus for now is the first system currently digging south into the northern Baja before taking aim at southern AZ Wednesday and Thursday. We expect mostly quiet and warm conditions the rest of today before shower chances resume Wednesday morning. As of now, the best chances for widespread rain will arrive later Wednesday lasting into Thursday afternoon.
For the rest of this morning plan on cloudy conditions and lingering light showers for far northern/western zones. Afternoon temperatures will still warm into the 71˚F-74˚F range around the Valley with periods of afternoon sun. South/southeast winds will be breezy at times in the 7-14mph range with gusts in the 20-30mph range (especially across the higher terrain areas). Overnight lows will only fall into the mid to low 50s under overcast with some isolated light showers.
For tomorrow plan on another mostly cloudy start to the day along with possible light showers (favored across our western zones). Daytime highs will briefly reach the 68˚F-70˚F range around the Valley. Breezy south/southeast winds will continue throughout the day with gusts in the 15-20mph range. The main moisture surge associated with our disturbance will reach AZ by Wednesday morning followed by increasing showers from southwest to northeast during the afternoon/evening into Thursday morning. This period will present our best opportunity for widespread rain with most areas seeing anywhere from 0.20”-0.60”. Highs on Thursday are forecast to remain in the 60s with lingering showers and potential storm chances into the afternoon before conditions finally begin to clear. We’ll have more details on rain amounts and timing in the next Outlook.
