515 FNUS28 KWNS 212050 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0248 PM CST Sat Feb 21 2026 Valid 231200Z - 011200Z An active fire weather pattern is expected across portions of the Florida Peninsula and the Southern/Central Plains through much of the extended forecast period. For Day 3/Monday, a mid/upper-level ridge is forecast over the Southwest with a mid/upper-level trough over the Southeast. Thereafter, the Southwest ridge is forecast to flatten while broad troughing (and enhanced mid-level flow) develops across much of the CONUS. At the surface, portions of Florida will remain in a very dry post-frontal regime Day 3/Monday while episodic lee surface trough strengthening occurs across the Central Plains Day 3/Monday through at least Day 8/Saturday. ...Day 3/Monday: Florida Peninsula and Southern Georgia... Elevated to near critical fire weather conditions are probable early Day 3/Monday morning across portions of the Florida Peninsula due to very poor overnight RH recoveries and lingering post-frontal breeziness. Although daytime temperatures will be relatively cool behind the front, critical conditions appear likely across portions of the Florida Peninsula (where 70% probabilities for Critical fire weather conditions have been introduced) due to the combination of low-to-extremely-low minimum RH values, strong northerly post-frontal winds, and receptive fuels owing to ongoing drought conditions. ...Day 3/Monday - Day 5/Wednesday: Southern/Central Plains... Relatively dry southerly/southwesterly return flow is forecast to increase across the southern Plains Day 3/Monday as lee troughing strengthens, which should promote Elevated fire weather conditions across portions of eastern New Mexico, the Texas/Oklahoma Panhandles, and far western Oklahoma. Fire weather conditions are forecast to become more widespread Day 4/Tuesday across the southern Plains as strong mid-level flow remains in place and the lee surface cyclone and associated pressure gradient strengthens further while developing southward. While critical fire weather conditions are most likely behind the dry line across portions of eastern New Mexico into the Texas Panhandle where strong downslope flow is expected, confidence is currently too low to introduce 70% probabilities for Critical fire weather conditions. Additionally, 40% probabilities for Critical fire weather conditions were expanded into portions of Oklahoma based on the latest ensemble guidance, where a dry return flow regime is forecast. Confidence is a bit lower Day 4/Tuesday across the Central Plains, with ensemble guidance offering differing solutions for the evolution of a developing surface cyclone in the lee of the Laramie Range. While critical probabilities were not introduced with this outlook, fire weather conditions are possible depending on the evolution/strength of the cyclone. Run-to-run model variability has increased somewhat for Day 5/Wednesday, with impactful differences in the strength and positioning of the surface low through the day over the Southern Plains. In turn, this decreases confidence in critical fire weather highlights across the area. Nevertheless, the 40% probability for Critical fire weather conditions was maintained as at least elevated fire weather conditions appear likely across much of the area. ...Day 6/Thursday - Day 8/Saturday: Southern/Central Plains... Ensemble model spread begins to increase Day 6/Thursday and into the next weekend, which precludes introduction of Critical probabilities beyond Day 5/Wednesday. Nonetheless, the mid/upper-level pattern continues to favor broad troughing across the CONUS, with enhanced mid-level flow and multiple short-wave impulses crossing the central United States. This flow pattern coupled with ongoing drought conditions (and little-to-no forecast rainfall) suggest fire weather conditions will likely linger across portions of the plains through at least Day 8/Saturday. ..Elliott.. 02/21/2026 ...Please see www.spc.noaa.gov/fire for graphic product... $$
