317 FNUS28 KWNS 192205 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0503 PM CDT Sat Apr 19 2025 Valid 211200Z - 271200Z Across the eastern US, ridging will favor dry conditions but with only modest winds through much of the forecast period. Mid-level flow will trend more zonal and weaken slightly over the next several days, before a more amplified pattern emerges mid to late week next week. Lee troughing and westerly flow will increase from the Rockies to the Southwest. This will tend to support an increase in fire-weather concerns midweek and beyond. ...Southwest and Great Basin... As flow aloft becomes more amplified, a stronger upper trough will eject eastward over the Rockies and high Plains supporting strong southwesterly flow a loft. A cooler air mass behind a remnant backdoor front over the southern high Plains will gradually warm and dry through early next week. Dry downslope winds will increase midweek as the main upper trough moves east. Elevated to critical conditions are possible D5/Wed and beyond. Uncertainty on the upper-level evolution remains fairly large, but ensemble agreement increases fire-weather concerns through next weekend. ...Central High Plains... As flow aloft becomes more zonal, westerly downslope flow is likely early next week. Downslope winds may reach critical criteria at times, but substantial uncertainty remains on diurnal RH minimums given the cooler surface temperatures and precipitation over the preceding days. Localized fire-weather concerns will remain possible, but widespread concerns are not expected. ...Southeast... Dry and occasional breezy conditions are possible over much of the Southeast and FL through next week. High pressure over the eastern US will support above normal temperatures and almost no precipitation. This could support some localized fire-weather risk, given the ongoing state of dry fuels and additional drought development. However, confidence in the coverage and intensity of fire-weather conditions is low as winds are not expected to be very strong beneath high pressure. ..Lyons.. 04/19/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
