Day 3-8 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0459 PM CDT Mon May 05 2025



Valid 071200Z - 131200Z



A building ridge setting up over the Western U.S. will bring warming

temperatures and a lighter wind regime to most of the region from

Day 3-5/Wednesday-Friday. A short wave riding along the northern

periphery of the ridge and subsequent dry, post-frontal winds could

present a fire weather concern across the High Plains of northern

Montana on Day 4/Thursday, but recent precipitation and expected

state of fuels should reduce wildfire spread potential so critical

probabilities were withheld. Model guidance consensus shows an

overall eastward accelerating wave pattern by the weekend ushering

in the next trough into the Western U.S. for Day 7-8/Sunday-Monday.

Supportive upper-level dynamics ahead of the trough interacting with

residual mid-level moisture will support faster moving thunderstorms

with limited rainfall across the Great Basin and portions of the

Intermountain West. However, current green-up phase of fuels should

limit ignition efficiency. In addition, increasing southwest flow

ahead of the trough supports a broad fire weather concern across the

Great Basin/Southwest Days 7-8/Sunday-Monday, but ensemble member

spread remains high enough, particularly with timing of trough, to

preclude critical probabilities at this time.
