<p>"The pool threatens that its water is colder than its frigid, morning air alternative"? But, um, rephrased to sound better maybe? Yeah... At least now you are comparing two things of the pool...</p>
<p>You probably didn't mean more suggestions from me, but...</p>
<p>First, I don't like my choice of "alternative." </p>
<p>Second, I have some random ideas:</p>
<p>"The pool threatens that, at daybreak, its water is colder than its frigid air counterpart"</p>
<p>"The pool threatens that, at daybreak, its water is more frigid than its air counterpart hovering before the dawn"</p>
<p>"The pool threatens that its morning water is more frigid than its air counterpart"</p>
<p>"The pool threatens that its dawn-kissed water is more frigid than its air counterpart"</p>
<p>"The pool threatens that its dawn-kissed water rips more shivers and goosebump-rubbing than its cloud-spattered counterpart" <-- went a little crazy on this one lol</p>
<p>Maybe not counterpart either... Check synonyms. You can obviously also mix and match with some of these.</p>
<p>@ EnglishTeacher88: How is it different from mine? </p>
<p>"The pool threatens that [the pool] water is colder than the cold morning air..."
vs.
"In the early morning, the pool water threatens to be colder than the air."</p>
<p>Does "is colder than" vs. "to be colder than" really make that much of a difference?</p>
