National October record (lower 48) smashed again at Peter Sinks this morning. Been to -45.5F. (-43.1C) so far. Watch out Alaska, your record is in jeopardy too! 3 hours yet before sunrise. Headed to nearby Middle Sink to "chase" the cold air. #utwx #akwx @NWS @NWSSaltLakeCity pic.twitter.com/xM2yQA4xZf
