The cold front has arrived in Cheyenne and it is already a record-breaker! From 1:05 to 1:35, the temperature plunged from 43 to 3 degrees, a FOURTY-DEGREE drop in just 30 minutes! This shatters our previous 1-hour temp drop record of 37 degrees, and we are still dropping! #wywx pic.twitter.com/twQcNgy9qx
