SYNOPSIS:  A Canadian winter storm system brought significant snow to the area over the weekend and bitter cold temperatures that will continue through today.  Snow began in the northwest Saturday and ended Monday, moving southeast.  Some locations saw significant snowfall such as Casper, WY, which saw up to 14.5", making it their 21st biggest snowstorm since 1937.  Only a few mountain Snotels also recorded that much snow this storm.

Low temperatures were mostly -15F to -25F across north and central Wyoming Tuesday morning and this morning, with wind chills as low as 40 below at times.  Temperatures are only expected to get to between -5F and -20F tonight into Thursday morning with highs getting into the teens to low 20's.
