This is such a vivid description of a brewing storm (real? metaphorical? Is anything ever completely one or the other?) The setting is blunt and brooding, the mood expectant. It feels like a storm that happens with no one to witness.

"hours churning like warm butter" <---- great.

A description of a scene that I find quite remarkable. I love the many descriptions in this piece as it makes it easy to visualize the piece and it makes the reader feel as if he/she has just witness this little storm. Also your wording in this piece is creative and unique.

Finding one part that stood out was impossible so I will tell you that I am thoroughly impressed by your poem. Great job and keep writing.
