Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
1023 AM CDT Sat Aug 29 2026

Valid 291700Z - 301200Z

No changes were made to the Elevated wind/RH area in place over
portions of the Pacific Northwest and adjoining regions as well the
area over the southern Plains. The latest forecast guidance remains
on track with previous outlook issuances. Surface observations as of
late this morning indicate south-southwesterly winds of 15-20 mph in
place over the southern Plains as the surface trough tightens the
pressure gradient. A well-mixed boundary layer amid hot surface
temperatures will support afternoon RHs below 20-25% across the
highlighted area.

Sufficient instability (CAPE near 100-500 J/kg) will support wet and
dry thunderstorms over portions of north-central WA later this
afternoon amid increasing dynamic lift within the left exit region
of the jet streak ahead of the approaching trough. While moisture
content ahead of this trough remains low (precipitable water values
near 0.5-0.6"), much below normal temperatures today and
accumulating rainfall likely on Day 2/Sunday where convection is
most likely to occur this afternoon. Continued cooler than normal
conditions and higher RHs persist through much of the coming week
over this area as well. While a few new lightning ignitions are not
out of the question due to dry (but moistening) fuels, they will be
significantly moderated by the aforementioned environmental
conditions over the next several days.

.PREV DISCUSSION... /ISSUED 1215 AM CDT Sat Aug 29 2026/

...Synopsis...
...Southeast Oregon into northeast California and northwest
Nevada...
Surface winds are expected to increase ahead of a boundary on
Saturday. Winds of 15-20 mph will be possible during the afternoon.
Elevated fire weather is expected within a narrow zone of 15-20% RH
that will reside between the surface boundary and richer mid-level
moisture/clouds to the south east.

...Southern High Plains into south-central Kansas...
The presence of a surface trough from the central Plains into the
southern High Plains will allow 15-20 mph to develop by the
afternoon. Hot temperatures underneath the upper ridge will help
lower humidity to 20-25%. Drought-stressed fuels will support an
elevated fire weather threat despite recent rainfall.
