显示当前事件，然后降低wordpress中的顺序

I have events on a WordPress site. Some events are in the future. currently when I display them they are in the correct order but I am needing the current event to display first then show the rest of the events in descending order.

I appreciate any assistance.

Here is my current code

$today = date('dmY');
$args = array (
    'post_type' => 'posts_events',
    'meta_query' => array(
        array(
            'key'       => 'start_date',
            'compare'   => '<=',
            'value'     => $today,
        ),
         array(
            'key'       => 'end_date',
            'compare'   => '>=',
            'value'     => $today,
        )
    ),
);
?>
