From Twitter https://twitter.com/: From a 33 morning low to a 74 afternoon high! How?! DRY AIR. The air across TX is dry as a bone. Dry air heats and cools much easier than air with a lot of moisture. Add in the sunshine & southwest breeze...it's no wonder we saw such a jump! #wfaaweather https://twitter.com/JesseWFAA/status/940008560611733504/photo/1 https://chirp.cooleysekula.net/attachment/45199
