It will be possible to trigger wind slabs in isolated areas immediately adjacent to the Cascade Crest, namely the Salmon La Sac. Although small, slabs could be actively growing deeper in the La Sac if new snow and wind clip the area. Throughout the rest of the zone, triggering small, older slabs is unlikely.
If the wind blows strongly enough, you can use blowing snow as a sign that slabs are being built in lee terrain. More reliable clues to look out for are fresh, soft cornice or drift formation, textured surfaces, and shooting cracks in new slabs. While unlikely to bury you, consider the consequences of being carried downslope with all of the hazards still exposed in terrain right now.
There are widespread buried weak layers within the snowpack that could be finally overloaded by slabs building on top. It's worth a minute of your time to dig small hand pits and check the bond between interfaces. A wind slab failing on one of these layers has the potential to propagate more widely than expected.

Cracking in small amounts of wind loaded snow was observed in the Salmon La Sac earlier this season. You might see similar conditions on Thursday.
