Snowy conditions will head Sunday from the Rockies into the Southern Plains, while a cold front brings more active weather to the Southeast. Meanwhile, most of the nation will remain under quiet conditions while these two weather features start to merge over the South late Sunday.
A low pressure trough that moved into the central Rockies from the Pacific Northwest will continue moving southeastward. This system will bring snow showers to northern New Mexico. By evening, the leading edge of this system will reach into northern Texas. Expect snowfall accumulations of 2 to 4 inches across New Mexico's higher elevations and a messy mix of freezing rain and snow in northern Texas.
East of this system, a slow-moving frontal boundary will linger over the Southeast. Moisture from the Gulf of Mexico will continue fueling this system, allowing scattered showers and thunderstorms to pop up from eastern Texas, over the Lower Mississippi River and Tennessee Valley, and reaching into the Carolinas by evening. Some of these storms may turn severe with heavy rainfall and strong winds. Expect rainfall totals to range around 1 inch, up to 2 inches likely in areas of thunderstorm development.
Elsewhere, the Midwest and Ohio River Valley will remain quiet and dry as high pressure dominates. This will allow for plenty of sunshine and warm temperatures. Expect high temperatures to remain 15 to 25 degrees above seasonable across the region.
Temperatures in the lower 48 states ranged Saturday from a morning low of 1 degrees at Alamosa, Colo., to a high of 90 degrees at Alexandria Esle, La.
