NWS Flagstaff

What forecasters said that day

The local office's own words before this red flag warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Flagstaff, AZ wrote its last area forecast discussion before this red flag warning went out at Jun 28, 9:47 AM MST, 2 hours 43 minutes earlier.

Area forecast discussion, Jun 28, 9:47 AM MST, 2 hours 43 minutes before
Area Forecast Discussion
National Weather Service Flagstaff AZ
947 AM MST Sun Jun 28 2026

.SYNOPSIS...Widespread dry conditions and gusty winds expected
again today, continuing the critical fire weather conditions.
Winds will decrease for the week, but still remain breezy each
afternoon out of the southwest and single digit to low teen
minimum RH values will keep much of northern Arizona in near-
critical fire weather conditions. Afternoon temperatures will also
slowly increase through the week, but remain mostly below normal
for this time of year.

&&

.DISCUSSION...A large low pressure system over the Pacific
Northwest continues to bring gusty southwest winds and mostly dry
conditions across much of northern Arizona. With winds forecast to
gust near 40-45 mph this afternoon and minimum RH values mostly
below 15%, the Red Flag Warning and Wind Advisory products remain
in effect through this evening.

The first noticeable break from these roaring winds will be
Sunday night/Monday morning, when typical light/terrain driven
winds return for our CWA. Much of the Western CONUS will remain
under a trough through the week, keeping afternoon winds out of
the southwest but speeds should drop to about 10-20 mph. Daytime
temperatures will creep up each day, but will remain below normal
for this time of year through the week. Dry conditions will also
be sticking around with minimum RH values dropping to single
digits across much of northern Arizona. This will keep us in a
near-critical fire weather conditions state. There may need to be
consideration for additional Red Flag Warnings for the eastern
portions of the Little Colorado River Valley for Monday, but no
additional products have been issued at this time.

You may be wondering if precipitation is going to return anytime
soon, and the only glimmer of hope is for some moisture to creep
in from the east by next weekend, but confidence is very low at
this time.

&&

.AVIATION...Sunday 28/18Z through Monday 29/18Z...VFR conditions
forecast through the period, with areas of HZ/FU near KFLG & KGCN
terminals due to local wildfires. FU may also impact KSEZ during
the overnight period. Southwest winds 20-30 kts with gusts 35-45
kts through 02Z-04Z, then lighter winds of 5-15 kts forecast to
return tonight into early Monday morning.

OUTLOOK...Monday 29/18Z through Wednesday 01/18Z...VFR conditions
expected through the period. HZ/FU possible near KFLG, KGCN, and
KSEZ terminals due to local wildfires. Expect southwest winds
10-20 kts, gusting 25-30 kts each afternoon. Light and variable
winds forecast during the overnight periods.

&&

.FIRE WEATHER...Sunday and Monday...Critical fire weather conditions
continue today, with gusty winds and widespread low RH values. A Red
Flag Warning and Wind Advisory remains in effect through this
evening for much of northern Arizona. Expect winds to be out of the
southwest 20-30 mph gusting near 40-45 mph this afternoon, becoming
lighter on Monday.

Tuesday through Thursday... Breezy and dry conditions forecast to
continue. Expect southwest winds between 10-20 mph each afternoon
with gusts near 25-30 mph. Minimum RH values will mostly be below
10% each day, keeping much of northern Arizona in near-critial fire
weather conditions.
