NWS Forecast Office Phoenix, AZ

Lingering light rain showers and areas of drizzle are continuing across central and eastern AZ early this morning. This activity will slowly come to an end through this afternoon. A few isolated thunderstorms will remain possible with this activity. Activity is expected to end across the Phoenix Metro by the mid-morning hours and across eastern AZ by late this afternoon. Additional rainfall amounts of 0.00-0.25" with locally higher amounts are expected.

The unsettled pattern over the Southwest US continues, as yet another weather system dives southwest of the region Friday and brings rain chances through at least Saturday night as it slowly progresses northeastwards through AZ. Due to this system's unique trajectory, the locations most favored for higher multi-day rainfall totals will be Southwest AZ and Southeast CA. Multiple rounds of showers can be expected, with the highest rainfall rates likely Friday as dynamic forcing ahead of the system is maximized. A few isolated thunderstorms cannot be ruled out.

Rainfall totals with this next system (Thursday night through at least Saturday night) are likely to be higher out west, across Southeast California and Southwest Arizona. Forecast rainfall totals for the multi-day event average around 0.5-1.5" across lower desert locations out west, with higher totals upwards of 1.5" confined to higher terrain such as the Chocolate Mountains, Western Joshua Tree National Park, and potentially the Kofas, to name a few. Forecast rain totals across South-Central AZ generally average between 0.2-0.5" over the same period.
