Fig. 1: Current weather watch, warning, and advisory areas across the U.S. Discussion: The West U.S. is hit-hard by a widespread area of precipitation and high wind for late week. Winter Storm Warnings for heavy snow affect much of southwest Oregon/northwest California plus the Snake River Basin in Idaho to the northern Rocky Mountains (Fig. 1). Ahead of the storm, high wind warnings are issued for eastern Colorado. The Great Basin can expect snowfall and a Winter Weather Advisory is posted. A Winter Storm Watch is issued for the Wasatch Range in Utah. In the Northeast, yesterday’s storm is departing although high wind remains over the northern half of New England and lake-effect snows continue in western New York. The latest gas population weight HDD forecast indicates a consensus of all models which is warmer for next week and slightly warmer than the 30-year normal while the Dec. 9-15 forecast trends colder (Fig. 2).
