Day 1 Fire Weather Outlook

1123 AM CDT Sat Jun 15 2024

Valid 151700Z - 161200Z

The forecast is largely on track. The Elevated risk area was
expanded into portions of southeast Utah to account for expected
drier and breezier conditions with somewhat receptive fuels in the
area. Otherwise, see the previous discussion for further details.

.PREV DISCUSSION... /ISSUED 0206 AM CDT Sat Jun 15 2024/

...Synopsis...
A mid-level trough and attendant belt of enhanced west to
southwesterly flow moving across the Cascades into the Northern
Rockies will bring potential for breezy/dry downslope flow in the
lee of the Cascades across western Washington/northern Oregon within
the Columbia Basin on Saturday. Afternoon relative humidity
reductions to 15-25 percent will overlap sustained winds 15-20 mph
amid drying fuels. Locally Critical fire weather concerns will be
possible, though Critical winds appear too localized to include any
areas at this time. Additionally, some Elevated fire weather
conditions are likely in the Snake River Plain in Idaho where
sustained winds around 30-35 mph will overlap 15-20% RH and modestly
receptive fuels.

Ahead of the western US trough, a surface trough across southern
Nevada into western Arizona will bring breezy/dry conditions across
southern Nevada into southwestern Utah and northwestern Arizona,
where relative humidity reductions into the teens to single digits
will overlap sustained southwesterly flow around 10-15 mph within
critically dry fuels. Given sub-critical winds, an Elevated
delineation covers this threat well.
