A large trough of low pressure will be settled over the state of Wyoming for the rest of today, Wednesday, and New Year's Eve.  A series of faster-moving weather disturbances and cold fronts will also slide across the region during this time.  Expect partly to mostly cloudy skies, breezy to gusty winds, and only a small chance for flurries or light snow showers.  Generally small, if any, new snow accumulations are expected during this time, but there could be a few isolated slick spots on roadways.  Temperatures will also be bitterly cold, with highs in the teens.  Higher pressure will then start to build over the region on New Year's Day, Saturday, and Sunday.  This will bring quiet and more settled weather conditions to the state during this time.  Temperatures will remain colder than normal on New Year's Day.  Expect not as cold and closer to average temperatures by Saturday and Sunday.
