Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0354 PM CST Tue Dec 30 2025 Valid 011200Z - 071200Z ...Synopsis... An embedded mid-level short wave moves into the Southwest Days 3-4/Thursday-Friday as a more zonal flow pattern emerges across the central U.S. while more pronounced troughing continues across the Northeast. The arrival of stronger westerly flow aloft subsequent strengthening lee cyclone across the southern Plains could bring stronger winds to portions of the southern High Plains and West TX on Days 3-4/Thursday-Friday. A broad upper-level ridge builds over the central U.S. over the weekend into early next week straddled by troughing across the West and Northeastern CONUS. ...Southeast U.S.... Although dry conditions across the Southeast will persist with minimal recent precipitation and moderately dry fuels in place, winds should be relatively light with a more diffuse surface pressure gradient in place. Increasing boundary layer moisture ahead of a surface cyclone on Day 4/Friday will further limit the fire weather threat across the Southeast and FL, with rainfall expected Day 5/Saturday as the surface low and frontal boundary translates eastward along the northern Gulf Coast. ...Southern/Central Plains... Lee surface troughing and increasing westerly flow aloft will promote enhanced surface winds across the Southern Plains on Day 3/Thursday before a cold front moves through the region Day 4/Friday. However, anomalously high mid/upper-level Pacific moisture and cloud cover being ushered into the Southwest could be a considerable mitigating factor in suppressing a greater fire weather concern in terms of RH reductions across the Southern Plains late this week, limiting predictability in a broader critical fire weather event. Ensemble guidance consensus continues to show an overall favorable mid/upper level westerly flow pattern for dry, downslope conditions across the central and southern High Plains early next week. However, timing and magnitude of surface cyclone development and return flow events is still nebulous, which precludes introduction of critical probabilities at this time. ..Williams.. 12/30/2025 ...Please see www.spc.noaa.gov/fire for graphic product...Read more
