An active pattern across the Heartland...
Across the Corn Belt, showers and locally severe thunderstorms precede and accompany the passage of a strong cold front. The heaviest rain is falling from Ohio into southeastern Missouri. Windy, colder conditions trail the cold front across the western Corn Belt.
On the Plains, cooler, breezy conditions have replaced record-setting weekend warmth. Light snow was falling Monday morning in parts of Texas’ northern panhandle, where Sunday’s high temperatures ranged from 90 to 100°. However, more precipitation is needed on the drought-affected central and southern Plains to significantly ease stress on pastures and winter grains.
In the South, locally severe thunderstorms in the vicinity of a cold front stretch from Arkansas into central Texas. Meanwhile, Southeastern fieldwork is proceeding in advance of the cold front.
In the West, warm, dry weather is promoting fieldwork in California and the Desert Southwest. In contrast, showery weather prevails from the Pacific Northwest to the northern Rockies.
During the next 24 hours, a low-pressure system over the Midwest will race into eastern Canada, dragging a strong cold front to the East Coast. Showers and locally severe thunderstorms will accompany the cold front, while windy, cooler weather will trail the front. However, warmth will quickly return to the central and southern Plains by Tuesday and expand across much of the eastern half of the U.S. by late in the week.
In contrast, cool air will overspread the West, accompanied by a return of unsettled, showery weather.
Looking ahead, the 6- to 10-day outlook calls for above-normal temperatures in most areas from the Plains to the East Coast, while cooler-than-normal weather in parts of the Pacific Coast States and the Southwest. Meanwhile, near- to below-normal precipitation across the majority of the U.S. will contrast with wetter-than-normal conditions in the Pacific Northwest and from the Ohio Valley and lower Great Lakes region into the Northeast.
