building over eastern Arizona and New Mexico thru tomorrow will
bring another couple of degrees of warming on Friday with
localized low desert areas briefly hitting triple digits. Winds
kicking up a bit tomorrow but more so on Saturday associated an

portions of the White Mountains. Highs dropping back to around
normal this weekend then turning much warmer next week with more
widespread triple digit highs to close out the month.

Outside the official 7 day forecast period or into the first full
