####018002483#### FNUS28 KWNS 172150 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0348 PM CST Wed Dec 17 2025 Valid 191200Z - 251200Z Fire weather concerns are expected to persist through the remainder of the work week and into the weekend across the southern Plains and central/southern High Plains. A largely zonal upper-level flow regime is expected to persist through early next week before broad scale ridging becomes established over the south-central CONUS. This synoptic regime will favor lee troughing followed by frontal passages across the Plains with rain/snow chances for most regions, except for the Southwest/southern Plains where dry conditions will persist for the next several days. Long-range ensembles do show the potential for widespread precipitation late in the forecast period (D6/Mon to D8/Wed) for parts of the Southwest, but steady fuel drying is anticipated for the southern Plains/High Plains through next week. ...D3/Friday - High Plains/southern Plains... Dry conditions will prevail across the southern Plains early D3/Friday in the wake of Thursday's frontal passage. A surface high shifting eastward into the lower MS Valley will promote southwesterly winds across much of TX, OK, and KS. Coincidentally, an upper-disturbance moving across the northern Rockies will promote lee troughing along the High Plains, which will induce another downslope flow regime along the central Rockies and augment the pressure gradient over the Plains. 15-25 mph winds are anticipated within the dry return flow regime with RH reductions into the 15-25% range probable from the Permian Basin into western OK. In the lee of the Rockies, confidence in RH reductions is limited, but a strong wind signal coupled with drying fine fuels should promote at least a wind-driven fire weather concern. ...D4/Saturday - southern High Plains... A cold front associated with a northern Plains/Great Lakes surface low will gradually push into the southern Plains through the day Saturday. While confidence in how far south this front will progress by peak heating remains uncertain, the general consensus among guidance is that 15-20 mph westerly pre-frontal winds will support adequate downslope warming/drying for areas of elevated to critical fire weather conditions. ..Moore.. 12/17/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$ ####018000271#### FNUS38 KWNS 172150 PFWF38 DAY 3-8 FIRE WEATHER OUTLOOK AREAL OUTLINE NWS STORM PREDICTION CENTER NORMAN OK 0348 PM CST WED DEC 17 2025 VALID TIME 191200Z - 251200Z FIRE WEATHER OUTLOOK POINTS DAY 3-8 ...
