Sunny and unseasonably warm weather will prevail today ahead of an approaching cold front. Windy and dry conditions will result in critical fire weather conditions across east central Wyoming where Red Flag Warnings are in effect. The cold front will blast south across the area tonight bringing areas of rain and snow along and east of the Continental Divide. Precipitation is expected to change to all snow for most areas Thursday morning. Much colder temperatures will follow the front on Thursday with most highs in the mid 30s to mid 40s.
