That is exactly what was done with commercial aircraft carrying passengers that were routed over the North Sea (where the ash 'wasn't') and kept away from the mainland areas (where the ash 'was').
If this is considered acceptable why not fly samplers in the areas where the ash 'isn't' to confirm the forecast?
