The Elevated risk area was expanded into portions of southeast Utah to account for expected drier and breezier conditions with somewhat receptive fuels in the area. Otherwise, see the previous discussion for further details. ..Supinie.. 06/15/2024 .PREV DISCUSSION... /ISSUED 0206 AM CDT Sat Jun 15 2024/ ...Synopsis... A mid-level trough and attendant belt of enhanced west to southwesterly flow moving across the Cascades into the Northern Rockies will bring potential for breezy/dry downslope flow in the lee of the Cascades across western Washington/northern Oregon within the Columbia Basin on Saturday. Afternoon relative humidity reductions to 15-25 percent will overlap sustained winds 15-20 mph amid drying fuels. Locally Critical fire weather concerns will be possible, though Critical winds appear too localized to include any areas at this time. Additionally, some Elevated fire weather conditions are likely in the Snake River Plain in Idaho where sustained winds around 30-35 mph will overlap 15-20% RH and modestly receptive fuels. Ahead of the western US trough, a surface trough across southern Nevada into western Arizona will bring breezy/dry conditions across southern Nevada into southwestern Utah and northwestern Arizona, where relative humidity reductions into the teens to single digits will overlap sustained southwesterly flow around 10-15 mph within critically dry fuels. Given sub-critical winds, an Elevated delineation covers this threat well. ...Please see www.spc.noaa.gov/fire for graphic product... $$
