...CRITICAL FIRE WEATHER AREA FOR THE SOUTHERN GREAT
BASIN...SOUTHWEST...AND CENTRAL ROCKIES...
...CRITICAL FIRE WEATHER AREA FOR THE SNAKE RIVER PLAIN...

An area of Isolated Dry Thunder was introduced over portions of
central/northern UT and western WY on Day 2/Sunday near the
previously mentioned frontal boundary. Isolated thunderstorm
coverage amid a significant sub-cloud dry layer, combined with
limited precipitable water near 1/2 inch, and quick storm motion
near 25-35 kts over receptive fuels will lead to the threat of dry
lightning ignitions in the morning hours and again by peak heating
in the early/mid afternoon hours.

Regarding the surface wind/RH threat, a few small changes were made.
The Critical area was expanded over much of northeast AZ as the
latest forecast guidance has trended toward strong winds over this
region amid the hot and very low RHs. Keep in mind that should
ignitions occur over this region, burn periods will continue to
extend well into the overnight hours with RHs failing to rise above
20-30% in almost all drawn areas of the southern Great Basin and
Southwest. The larger Elevated area was also expanded over much of
the Mojave Desert as well as northern NM and across much of the
Front Range of the central Rocky Mountains. With this expansion,
there are high elevation portions of the central Rocky Mountains
included that are may struggle to meet wind/RH criteria amid less
critically dry fuel conditions. The targeted Elevated to Critical
threat across portions of the Snake River Plain remains on track
from previous forecast issuances.

.PREV DISCUSSION... /ISSUED 0159 AM CDT Sat Jun 06 2026/

...Synopsis...
The upper-level low over the Northwest will advance towards the
Northern Rockies, as a surface low intensifies over the northern
Plains with the trailing cold front moving through the northern
Great Basin. This will bolster surface winds across parts of the
Southwest and central Rockies mid a very dry air mass. Elevated to
critical fire-weather conditions are likely.

...Southern Great Basin and central Rockies...
Beneath the stronger flow loft, gusty surface winds are again likely
ahead of the cold front from southern NV, into UT, parts of western
CO and southwestern WY. Aided by deep mixing and 30-40 kt of
southwest flow aloft, afternoon surface winds of 20-30 mph are
expected. Poor to nonexistent overnight humidity recoveries and
afternoon minimums of 5 to 15 percent will exacerbate critical fuels
across the Southern Rockies and Southwest. The combination of very
dry air, strong winds and receptive fuels will favor several hours
of widespread critical conditions Sunday afternoon.

...ID...
Beneath the upper trough, continued strong southwesterly flow aloft
will bolster surface winds through the Snake River Plains and
southern ID. Gusty surface winds of 20-35 mph and RH of 10-20% will
support several hours of elevated to critical fire-weather
conditions Sunday. Gusty wind and low humidity may extend farther
eastward into ID and far western WY, but here fuels here have
received recent rainfall and are less receptive.
