Day 1 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

1141 AM CDT Thu Jun 26 2025



Valid 261700Z - 271200Z



...NO CRITICAL AREAS...



A subtle mid-level short wave trough will exit the Great Basin into

the Northern Rockies this afternoon. Mid-level flow and surface

pressure gradients will relax across the Great Basin as the trough

ejects northeastward through the day although resulting in sustained

west-southwest surface winds around 10-15 mph during peak boundary

layer mixing. However, locally elevated fire weather conditions,

particularly leeward of mountain ranges within the Great Basin and

northwestern Arizona and southwest Utah, can be expected today.

Stronger winds of 15-25 mph are likely across the upper Snake River

Plain but fuels are not as receptive to wildfire spread as regions

farther south.

...Synopsis...

Fire weather concerns are expected to remain limited for today

across the country. Widespread rainfall over the eastern two-thirds

of the country will limit fuel status for most locations. West of

the Rockies, dry conditions will continue with afternoon RH minimums

in the teens expected. However, the strongest low/mid-level flow is

expected to remain across the Pacific Northwest (where RH reductions

won't be as pronounced) ahead of a low-amplitude mid-level trough.

Localized elevated conditions may materialize across portions of

southern ID and northern NV where the overlap of dry conditions,

receptive fuels, and modest surface winds (15-20 mph) is most

probable. Latest high-res ensemble guidance generally shows a weak

signal for widespread and/or persistent elevated conditions, which

limits confidence in the overall fire weather threat.
