Wordpress - get_permalink to return page_id instead of slug in %postname% permalink setting

So, I have wordpress site with http://ift.tt/1mXgIw6 in permalink setting.

I want to echo get_permalink(), which showing http://ift.tt/1DjBC2W result

but when I did echo get_permalink(), it's return http://ift.tt/1DjBEaQ. I know it's not an error because the permalink setting is %postname%.

I want to use it like this :

echo '<a href="'. get_permalink() .'&get_weather='. $weather .'"></a>';

to make link result like this :

<a href="http://ift.tt/1DjBEYq"></a>

instead of this result:

<a href="http://ift.tt/1DjBEYs"></a>

So, is it possible to get result of http://ift.tt/1DjBC2W while echo-ing get_permalink() with %postname% (or other permalink setting option) as the permalink setting? please explain how

Thanks.
