Day 1 Fire Weather Outlook 
NWS Storm Prediction Center Norman OK
0157 AM CDT Sat May 28 2022

Valid 281200Z - 291200Z

...CRITICAL FIRE WEATHER AREA FOR PORTIONS OF THE SOUTHWEST AND
SOUTHERN HIGH PLAINS....

...Synopsis...
Moderate southwesterly flow aloft over much of the western US is
forecast to intensify ahead of a deepening mid-level trough and jet
streak across the West Coast. A pair of surface cyclones will
intensify west and east of the Rockies, supporting strong surface
winds through much of the day. Warm temperatures and low humidity
will continue to keep fuels dry and receptive to fire spread. The
favorable overlap of a warm, dry and windy conditions will support
widespread critical fire weather concerns across the Southwest and
southern High plains Saturday.

...Southwest and Southern High Plains.
Low-level winds are forecast to gradually increase through the
morning in response to strong surface heating/mixing and deepening
low pressure over the southern Great Basin. By midday, flow aloft is
forecast to strengthen as the main western US trough approaches,
bolstering southwesterly low-level flow to 20-30 mph across much of
the Four Corners and Southwest. The deep mixing/warm temperatures
will also support dry conditions with widespread surface RH of
10-15%. The overlap of strong and gusty surface winds should easily
support widespread critical fire weather concerns across much of the
southern Great Basin, Four Corners and Southwest Saturday.

Farther to the east across the southern High Plains, strong
downslope winds are expected to increase south of the strengthening
lee low. Widespread winds of 20-25 mph appear possible along with
warm temperatures and afternoon humidity of 8-15%. Widespread
critical conditions are expected within drying fuels. Localized
high-end critical and extremely critical conditions may also develop
for a few hours across portions of northeastern NM, where surface
gusts aided by local terrain and a subtle mid-level jet may reach
30+ mph.
