Get the post thumbnail URL and assign to variable

I'm having a very strange issue. All I want to do is get the thumbnail url and assign it to a variable. Here is my code.

<?php /* Template for displaying content of MH Posts Large widget */ ?>

<article class="post-<?php the_ID(); ?> mh-posts-large-item">
<figure class="mh-posts-large-thumb">

<?php

$form_image = 'blank';

if (has_post_thumbnail()) {
        $form_image = the_post_thumbnail_url('mh-magazine-lite-content');

?>

Basically, if the post has a thumbnail I want to store the actual URL of the thumbnail used in that variable for later use. However, instead of doing that it just prints the URL on screen and doesn't actually seem to put it in the variable.

I don't understand why and I would definitely appreciate any help! :)

Looking at the official documentation:

function the_post_thumbnail_url( $size = 'post-thumbnail' ) {
    $url = get_the_post_thumbnail_url( null, $size );
    if ( $url ) {
        echo esc_url( $url );
    }
}

So the_post_thumbnail_url only outputs the URL it gets from get_the_post_thumbnail_url and doesn't return anything. Thus the solution is to use get_the_post_thumbnail_url directly.
