.PREV DISCUSSION... /ISSUED 0202 AM CDT Mon May 20 2024/

...Synopsis...
A mid-level jet streak will overspread the Southwest this afternoon
as a mid-level trough amplifies across the western CONUS. A deeply
mixed boundary layer is expected across Arizona and New Mexico with
temperatures in the 90s. Some of this stronger flow will mix to the
surface amid the deep boundary layer. In addition, lee cyclogenesis
will tighten the pressure gradient in the region and aid in stronger
surface winds. Sustained surface winds of 25 to 30 mph are expected
across New Mexico with some sustained winds over 30 mph in northern
Arizona. Single-digit relative humidity is also expected across most
of the region. Fuels have started to dry to critical levels across
portions of eastern and northern Arizona. Therefore, a Critical
delineation is warranted.
