A significant cold wave ahead...
During the next few days, a variety of weak disturbances will influence weather conditions across the U.S. Southeastern rainfall will end on Thursday, following by late-week snow showers from the Great Lakes region into the Northeast. Occasional precipitation will continue in the Northwest.
During the weekend, a developing storm over the nation’s mid-section may produce some light but much-needed precipitation on the southern Plains, while snow will return to parts of the northern Plains.
A significant cold wave outbreak will begin to affect much of the northern and central U.S. during the weekend.
Looking ahead, the 6- to 10-day outlook calls for near- to below-normal temperatures nationwide, except in Maine. The greatest likelihood of cold conditions will stretch from the northern Plains into the Southeast.
