the temperature that burns you twice — once cold, once again the next morning
means Covered with, made of, or feeling like ice — or, of a person's manner, coldly unfriendly.
from From Old English īsig, the adjective form of īs, 'ice,' a word shared across the Germanic languages (German Eis, Old Norse íss). The figurative sense of an 'icy' look or tone — frosty without a flake of actual frost — is a later metaphorical chill, the same instinct that lets us call a cold reception 'frosty' or a glare 'frozen.'
