Gusty Northeasterly surface winds will surface below passes late this morning and early afternoon, then winds will begin to diminish later today as the offshore pressure gradient weakens.

SYNOPSIS FROM THE PHOENIX OFFICE
A weak low pressure system will continue to strengthen today along the south central Arizona, Mexican border. This system will circulate an increasing amount of moisture north into central and eastern Arizona, for a good chance of showers and thunderstorms. The low pressure system will begin to track northeastward tonight, moving toward the four corners on Friday. This will continue to produce unsettled conditions in central and eastern Arizona through Friday. Clearing skies with warmer temperatures are forecast to develop this weekend, through the middle of next week
