Areas of low pressure were expected to develop along the front, continuing rain and high-elevation snow in the Rockies and the Southwest. Precipitation in the Southwest would also be enhanced by a Pacific storm moving in from California. Temperatures in these regions were forecast to drop as the system brings snow accumulation of about 3 to 5 inches in the higher elevations, with locally higher totals across the higher peaks. The lower elevations should remain mild and see mostly rain showers during the day.

On the eastern side of the cold front, another low was forecast to move into the southern Mid-Atlantic by Thursday evening. Bands of rain were expected from the central Gulf Coast to parts of the Southeast, while snow and bands of freezing rain were expected from parts of the southern Ohio Valley to Virginia and North Carolina.

To the north, most of the lake-effect snow in the Great Lakes would taper down through the rest of the week, while periods of heavy snow may persist to the southeast of Lake Ontario in New York through Thursday morning. Meanwhile, a wintry mix precipitation from eastern North Dakota through central Illinois was forecast to taper off through Thursday morning. Light snow accumulations and slick roads in these areas may slow the morning commute.

Temperatures in the Lower 48 states Wednesday ranged from a morning low of minus 24 degrees at Land O'Lakes, Wis., to a high of 84 degrees at San Angelo, Texas.
