Cooler air settles into the Midwest

Cooler air settles into the Midwest

Across the Corn Belt, a cold front has exited southern and eastern portions of the region. In the front’s wake, cooler, drier air is overspreading the Midwest. Indianapolis, Indiana, which experienced a record-dry July, will probably see its record-setting, 23-day (July 17 – August 8) streak of 90-degree readings end Tuesday.

On the Plains, cooler air is inching into Oklahoma and northern Texas, but very hot weather persists across the remainder of the drought-devastated south-central U.S. Meanwhile, dry weather has returned to the central Plains, following beneficial rainfall. Cool weather prevails on the northern Plains, where summer crops continue to develop at a slower-than-normal pace.

In the South, hot weather continues to stress pastures and rain-fed summer crops in the Gulf Coast and southern Atlantic States. However, a cold front is entering the region from the northwest, providing beneficial showers and thunderstorms across the Mid-South.

In the West, mild, mostly dry weather continues to promote crop development and fieldwork, including Northwestern winter wheat harvesting. Showers are lurking near the U.S.-Mexico border, while cool conditions linger along the immediate Pacific Coast.

A stalling cold front will mark the boundary between hot weather across the Deep South and markedly cooler air from the northern and central Plains into the Northeast. The front will remain a focus for showers and thunderstorms through mid-week. During the mid- to late-week period, however, a new batch of rain will develop across the northern and central Plains and spread eastward. By week’s end, heat will begin to build across the western one-third of the U.S.

Looking ahead, the 6- to 10-day outlook calls for near- to above-normal temperatures across the majority of the U.S., while cooler-than-normal weather will be confined to areas along the Pacific Coast and from the upper Mississippi Valley into the Northeastern and Mid-Atlantic States. Meanwhile, near- to below-normal rainfall across much of the nation will contrast with wetter-than-normal conditions in the Northeast and the Pacific Northwest.
