Area Forecast Discussion
National Weather Service Flagstaff AZ
428 PM MST Tue May 26 2026

.SYNOPSIS...Windy and cooler conditions will continue through
Friday with a trough over the Great Basin. Warmer conditions and
lighter winds return over the weekend.

&&

.DISCUSSION...Temperatures will remain below average for the rest
of the week as an unseasonably cold upper level low parks over
Reno for the next few days. This is a little farther west than
originally thought and this places some of the stronger winds a
little further west tomorrow. Those western zones get close to
Wind Advisory criteria but have held off issuing one for now. It
will still be a breezy day across most of the area and with
relative humidity levels dropping, a Red Flag Warning has been
issued for portions of northcentral Arizona for Wednesday. On
Thursday the low will shift a little further southeast which will
give our region another breezy day and could lead to another Red
Flag Warning for portions of the region, with zones a little
further east likely being added. Unfortunately the system doesn`t
come south far enough to really tap into any moisture so no
precipitation is expected.

By Saturday the low begins to lift northeastward, dying out as it
does. A ridge building over the central part of the country puts
our region under a southwesterly flow aloft which will keep things
dry with high temperatures warming to average this weekend, and a
little above average by early next week.
