Post Preview Image/Text Alignment Issues

I am aware of how to manage the alignment of images and text within a post. However, my question is: How do I manipulate the alignment of the feature image and preview text that readers see before they even choose to click on a post?

Consider the very first (bottom) post preview on the page I’ve linked to.

Currently, my post preview has my (huge!) featured image sitting above the first few lines of text from my post. When you click to read the post, though, the image is aligned left whereas the text wraps around the image to the right. I want my preview image/text alignment to match my post image/text alignment.

Suggestions?
