It might sound obvious, but making sure the Google app has permission to access your location can rule out a simple hitch.
To check, open Settings, then tap "Apps & notifications." Next, tap "See all X apps," find "Google," then select "Permissions." If the slider next to "Location" is not blue, tap it to enable the permission, then restart your phone to see if the weather shows up on your lock screen.
