The weather system passing through the Desert Southwest late week into this weekend will bring chances for a few rounds of scattered showers across the area, and perhaps even a few isolated, weak t-storms on Saturday. Rain totals across the South-Central AZ lower deserts will mostly remain light, with probabilities for 0.25-0.50+" less than 50% across the Phoenix Metro Area. Better precipitation totals will be focused over southeast AZ and higher terrain areas east of Phoenix.
