Yes, it was a bit chilly on Wednesday, but not as cold as records show it could be. Lander reached a -13°F at 11:53 p.m. Wednesday night, but the record cold temperature for the day was -25°F set way back in 1909.  Riverton’s low on Wednesday was recorded at nearly the same time, 11:42 p.m. , with a -5°F reading. Riverton’s all time cold temperature was -8°F set in 2009.

For today, NWS  said “mainly very cold weather would stay around through the weekend. A couple of minor disturbances may bring some light snow or flurries to Wyoming on the weekend and on Monday, but cold temperatures would remain in place. A chance for some warmer weather may arrive for the state later next week.”
