Across the Corn Belt, a steady rain is falling from the upper Mississippi Valley eastward into Michigan. Most Midwestern fieldwork remains on hold due to wet weather; cool, soggy soils; and lowland flooding.
On the Plains, cool, mostly dry weather prevails, except for lingering heat in southernmost areas (e.g. the southern half of Texas). Wildfires remain a threat on the drought-ravaged southern High Plains.
In the South, a band of showers and thunderstorms stretches from Kentucky southward to the central Gulf Coast. Rain is aggravating wet conditions in parts of Kentucky and Tennessee, but is providing limited drought relief in Louisiana and environs. Fieldwork is advancing in the Southeast.
In the West, unusually cool weather prevails. Isolated rain and snow showers stretch from the Pacific Northwest to the northern and central Rockies. Fieldwork is proceeding across California and the Southwest, although wildfires remain a concern in parts of Arizona and New Mexico.
An active weather pattern will continue through mid-week across the eastern half of the U.S., as a low-pressure system drifts from the central Corn Belt into the Great Lakes region. Locally severe thunderstorms will remain active along the storm’s trailing cold front, resulting in isolated tornadoes and as much as 4 to 6 inches of rain. Some of the heaviest rain will fall across the Mid-South and the lower Ohio Valley. Farther north, wet snow will accumulate in the upper Great Lakes region.
In the storm’s wake, mid- to late-week freezes may occur as far south as the central High Plains.
Farther west, cool, showery weather will linger across the Northwest, while dry conditions will persist from California to the southern High Plains.
Looking ahead, the 6- to 10-day outlook calls for near- to below-normal temperatures and near- to above normal precipitation across the majority of the U.S. However, warmer-than-normal weather will prevail in California, the Southeast, and the Desert Southwest, while drier-than-normal conditions will affect the Four-Corners States and the central and southern High Plains.
