1. Preheat oven to 375°.
2. To prepare the filling, combine cherries, 1/3 cup granulated sugar, cornstarch, juice, almond extract, and salt in a large bowl; toss gently. Spoon cherry mixture into an 11 x 7–inch baking dish coated with cooking spray.
3. To prepare topping, lightly spoon flour into a dry measuring cup; level with a knife. Combine flour, oats, brown sugar, and 1/8 teaspoon salt in a medium bowl, stirring with a whisk. Cut in chilled butter with a pastry blender or 2 knives until mixture resembles coarse meal. Stir in sliced almonds. Sprinkle oat mixture evenly over cherry mixture. Bake at 375° for 45 minutes or until filling is bubbly and topping is crisp. Let stand 5 minutes; serve warm.
