An active upper-wave pattern will persist across CONUS with another upper-level trough moving into the Western U.S. by Day 5/Sunday, gradually pushing into the Eastern U.S. through Day 8 where widespread rainfall is expected. Fire weather concerns should remain concentrated across portions of the Southwest where dry fuels and recent active fire activity amid drought conditions have occurred. A broad ridging pattern begins to build across the West by the middle of next week promoting generally light surface winds but above normal temperatures and dry conditions, which will aid in the curing/drying of fuels. ...Southwest... A multi-day fire weather threat will persist across parts of the southwest through early next week. Modest mid-level flow over a well-mixed boundary layer should allow for gusty southwest winds across southeastern Arizona and southern New Mexico on Day 4/Saturday. A mid-level jet max rounding the base of the incoming upper-level trough into the western U.S. should promote at least Elevated if not Critical fire weather conditions across southern New Mexico where dry fuels and drought persist on Day 5-6/Sunday-Monday. 40 percent Critical probabilities were added to reflect higher confidence of fire weather threat. ..Williams.. 05/14/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
