In the West, a winter-like storm near the Pacific Coast is producing heavy rain and halting fieldwork in northern and central California. Rain is also overspreading the Pacific Northwest, while a few rain and snow showers linger in the Rockies.

On the Plains, cool weather continues to slow the emergence and development of recently planted winter wheat. Light rain is falling in some areas, limiting summer crop harvesting and other fieldwork. During the weekend, freezes ended the growing season as far south as western Oklahoma and northern Texas.

In the Corn Belt, the growing season has ended in the Dakotas, Nebraska, Minnesota, Iowa, Wisconsin, and Michigan. Freezes were also noted across the northern halves of Missouri and Illinois. The freezes, which occurred roughly on schedule, halted the accumulation of mass in grain corn that was not fully mature. Only a small percentage of freeze-affected soybeans were immature (not dropping leaves).

In the South, wet weather is returning to areas from the Delta westward. Rain is providing additional drought relief in southern Texas, but further threatening the quality of unharvested crops in the Delta.

Outlook: Cool weather will persist across the eastern half of the U.S. for the remainder of the week, but warmth will return to the West. Along and near the West Coast, an early-season storm will produce 3 to 6 inches of rain as far south as central California. Meanwhile, two disturbances crossing the Southeastern and Mid-Atlantic States could produce 1 to 3 inches of rain. Some light showers will affect the Midwest, although mostly dry weather will prevail in the Great Lakes region. The NWS 6- to 10-day outlook for October 18-22 calls for near- to above-normal temperatures and near- to below-normal precipitation across the majority of the U.S. Cool, wet conditions will be confined to the northern High Plains and the Northwest. Warm weather will be most likely from Texas to the Great Lakes region, while dry conditions will be most likely from the Ohio Valley into the Northeast.
