Across the Corn Belt, cool, dry weather prevails. Patches of snow remain across the Corn Belt, but any substantial snow cover is confined to the upper Midwest.
On the Plains, cold conditions persist, except for mild, breezy weather in Montana. Sub-zero temperatures were common Tuesday morning from eastern Colorado to the Dakotas. Snow cover is patchy and shallow on the central High Plains, where recent and ongoing cold weather is a concern for already drought-stressed winter wheat.
In the South, rain stretches from the central Gulf Coast into the southern Mid-Atlantic region. Meanwhile, warm, dry conditions persist in the southern Atlantic States. In stark contrast, frozen precipitation (mostly freezing rain and sleet) is causing significant travel disruptions from northeastern Texas into the Mid-South.
In the West, parts of California’s Central Valley and the Desert Southwest are experiencing another freeze, although temperatures are generally higher than at the height of the cold snap—which occurred during the weekend.
During the next 24 hours, a wave of low pressure propagating northeastward along a stalled front will help to focus an area of precipitation across the Southeastern and Mid-Atlantic States. Rainfall in the vicinity of the front could reach 1 to 2 inches, while frozen precipitation (snow, sleet, and freezing rain) will cause travel and possible electrical disruptions from northeastern Texas into the northern Mid-Atlantic region. Late in the week, another disturbance will emerge from the south-central U.S., resulting in additional rain and snow in the Southeast.
The remainder of the country will stay dry, except for some snow across the nation’s northern tier. In the next few days, temperatures will rebound to near- or above-normal levels in many parts of the U.S., but a new surge of very cold air will begin to overspread areas east of the Rockies during the weekend.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures from the Pacific Coast to the High Plains, while colder-than-normal conditions will prevail across the eastern half of the U.S. Meanwhile, drier-than-normal weather across the majority of the nation will contrast with near-normal precipitation in the Great Lakes region and Deep South Texas.
