237 FNUS28 KWNS 152203 FWDD38 Day 3-8 Fire Weather Outlook NWS Storm Prediction Center Norman OK 0501 PM CDT Sun Jun 15 2025 Valid 171200Z - 231200Z ...Day 3-4/Tuesday-Wednesday... An eastward propagating upper-level short wave trough and associated increased mid-level flow will overspread the Southwest on Day 3/Tuesday. Critical probabilities were maintained as prolonged burn periods with poor to moderate RH recoveries and single digit daytime RH values combine with southwest winds of 15-25 mph across eastern Arizona and western New Mexico. A 40 percent probability area was added for the Columbia Basin for Day 4/Tuesday as another Pacific Northwest short wave trough moves into the region supporting downslope/leeward drying and breezy west winds across the area amid dry fuels. ...Day 5-8/Thursday-Sunday... A deepening upper-level trough begins to impact the western U.S. on Day 5/Thursday, promoting a multi-day fire weather threat across the Great Basin with fire weather concerns shifting east into the Southwest and Intermountain West into the weekend. Fuels will continue to dry across the region under an above normal temperature regime with dry, breezy southwest winds setting the stage for increased fire spread potential. Dry and breezy conditions could also impact ongoing active fires across the region. ..Williams.. 06/15/2025 ...Please see www.spc.noaa.gov/fire for graphic product... $$
