Monday, mid-day weather map

 A deep low pressure system and its associated, trailing cold front generates a wide-range of weather from the northern Plains to the Gulf coast.

Across the Corn Belt, rain is maintaining soggy conditions and keeping fieldwork at a standstill in most areas from the Mississippi Valley westward. Early Monday, heavy showers and thunderstorms are spreading into the lower Ohio Valley.

On the Plains, parts of eastern Oklahoma and northeastern Texas are in recovery mode, following Sunday night’s severe weather outbreak that included high winds, large hail, and isolated tornadoes. Currently, cool, dry, breezy weather is overspreading the southern Plains. Farther north, a chilly rain—mixed with some wet snow—is falling in parts of northern Nebraska and the Dakotas. In those states, the precipitation is maintaining exceedingly wet conditions, which has led to lowland flooding, significant fieldwork delays, and degradations in the quality of unharvested crops.

In the South, strong to locally severe thunderstorms stretch from the lower Ohio Valley to the western Gulf Coast region. Extremely heavy rain is occurring near the Texas coast, mainly just offshore. Meanwhile, dry weather has returned to the Southeast, following drought-easing weekend rainfall associated with the remnants of Tropical Storm Nestor.

In the West, scattered rain and snow showers stretch from the Pacific Northwest to the northern Rockies. Farther south, warm, dry, breezy weather prevails in California and the Desert Southwest. In portions of California, there is an elevated to critical risk of wildfires.

Yet another impressive storm system over the nation’s mid-section will drift northeastward, reaching the vicinity of Lake Superior by Tuesday. Showers and thunderstorms along the storm’s trailing cold front will sweep eastward, clearing much of the Atlantic Seaboard by mid-week. Subsequently, showers will return across parts of the East late in the week. Before the early-week storm moves into Canada, additional precipitation across the upper Midwest could reach 1 to 2 inches. Five-day totals could also reach 1 to 2 inches or more across the eastern one-third of the U.S., with some of the highest amounts expected in the central Gulf Coast region and the Northeast. In contrast, dry weather will prevail during the next 5 days from California to the southern half of the High Plains. Elsewhere, widespread showers from the Pacific Northwest to the northern Rockies will diminish by mid-week.

Looking ahead, the 6- to 10-day outlook calls for near- or below-normal temperatures nationwide, except for warmer-than-normal weather along California’s central coast and in the middle and southern Atlantic States. Meanwhile, near- or above-normal precipitation east of the Rockies should contrast with drier-than-normal conditions in much of the West.
