A low-pressure system drifting from the southern Plains into the upper Midwest will produce rain and wet snow. Some of the most significant snowfall accumulations will occur from northwestern Iowa to the western end of Lake Superior.
Early next week, a wave of low pressure developing along the original storm’s trailing cold front will result in widespread rain showers across the South and East.
Meanwhile, rain and snow showers will spread from the Pacific Northwest to the northern Plains.
The 6- to 10-day outlook calls for near- to below-normal temperatures nationwide, except for warmer-than-normal conditions in northern New England and from California into the Rio Grande Valley. Meanwhile, above-normal precipitation across the North will contrast with drier-than-normal conditions across the southern one-third of the U.S.
