An active pattern throughout the Heartland
A complex, wavy frontal boundary currently stretching from the northern Rockies into the Southeast will separate warmth on the central and southern Plains from unseasonably cold weather north of the front. As the front pushes slowly to the south, locally heavy rain will develop from the central Plains into the Mid- Atlantic, while notably cooler weather settles over the nation’s mid-section.
A strong area of cold high pressure behind the front will bring the threat of a weekend freeze to the Great Lakes region, possibly damaging fruit crops as well as other temperature-sensitive commodities.Meanwhile, rain and high-elevation snow will accompany the cooler weather into the Pacific Coast States.
Looking ahead, the 6- to 10-day outlook for calls for near- to above-normal temperatures nearly nationwide.
