Areas from the West Coast to the Midwest were bracing for snow Sunday.
A large low pressure system was on track to move through Southern California and into northern Mexico, and could produce high elevation snow in the Southwest and farther south.
A low pressure system also was set to move through the Great Lakes, leading cold air that will promote snow in the Upper Midwest. The cold air is expected to spill into the area from Canada, keeping temperatures cold overnight.
The low will allow a strong front to develop from the Southern Plains through the Ohio Valley. This front will likely pick up considerable moisture that will produce a line of moderate to heavy precipitation along the front.
Elsewhere, a Pacific front was forecast to move into the Northwest, providing rain and high elevation snow mainly in Washington.
Temperatures in the Northeast were predicted to rise into the 30s, 40s, and 50s, while the Southeast is expected to see temperatures in the 60s and 70s. The Upper Midwest will rise into the 30s and 40s, while the Rockies will see similar temperatures.
Temperatures in the Lower 48 states Saturday ranged from a low of 4 degrees at Stanley, Idaho to a high of 84 degrees at Laredo, Texas.
