Day 3-8 Fire Weather Outlook  

NWS Storm Prediction Center Norman OK

0428 PM CDT Mon Oct 20 2025



Valid 221200Z - 281200Z



...Days 3-4/Wednesday-Thursday...

Broad northwest flow south of a nearly stationary low over Quebec

will promote a dry downslope pattern in the lee of the Appalachians

midweek. Although dry fuels are present and low relative humidity is

expected, forecast guidance continues to show muted wind magnitudes,

limiting overall fire weather threat for the region. Reemergence of

southwest winds between the western periphery of a surface high

pressure over the southeastern U.S. and weak lee troughing in the

southern High Plains is expected across portions of Northwest

TX/western OK on Day 3/Wednesday. Generally weak surface pressure

gradients under an advancing upper-level ridge should limit wind

speeds. An approaching mid-level short wave and associated deepening

lee trough along with  an increase in boundary layer moisture and

cloud cover should limit fire weather concerns across the Southern

Plains Thursday.



...Days 5-7/Friday-Sunday...

Fire weather concerns will begin to decrease across much of the 

Southern Plains late this week, potentially even central TX where

very dry fuels exist. A mid-level short wave, associated surface low

and increasing boundary layer moisture will support showers and

thunderstorms across the Southern Plains and Mississippi Valley

through the weekend, reducing fire weather threats to the region. 



...Day 8/Monday...

A potential for offshore winds across Southern CA emerges early next

week as a deep trough enters the central U.S. with a cold surface

high pressure settling into the Intermountain West. Forecast

uncertainty in timing of offshore push and current and expected fuel

conditions precludes introduction of critical probabilities at this

time.
