SYNOPSIS

Expect dry and warmer weather over the weekend, then a chance of mainly rain showers Monday evening into Tuesday. Dry conditions with even warmer weather develops later next week.

DISCUSSION

A cut-off low is quickly retrograding to our southwest, and will stall off the coast of Baja California through the weekend. Warming temperatures with dry conditions across northern AZ can be expected through tomorrow. Breezy northeast winds today will become more localized into the evening/tomorrow morning, with much lighter winds setting in by tomorrow afternoon. By the beginning of next week, the cut-off low will finally begin to push eastward and bring a surge of moisture into the region. PW is forecast to exceed the 90th percentile for this time of year Monday evening into Tuesday. The trajectory/timing of the low will bring primarily rain showers, mostly to regions along/south of the I-40 corridor during this period. After the disturbance exits, there is good agreement in another warm and dry period as ridging builds along the west coast.
