Yes, you can make the dough ahead of time and store it in the refrigerator for up to 24 hours. After the dough has risen and you have shaped it into baguettes, cover them with plastic wrap and place them in the refrigerator. When you're ready to bake the baguettes, remove them from the refrigerator and let them come to room temperature for about 30 minutes before baking. This will help the baguettes rise properly in the oven and achieve a crispy crust.
