Title: Cool and Wet May Weather Continues for Many

The rain keeps coming for many areas of the plains, Rockies, Great Basin and western Corn Belt. The jet stream pattern remains stuck in gear and will continue to be stagnant for at least another two weeks. The end result will be what is called a “wave train”. A wave train is when a series of storm systems are lined up over the Pacific Ocean one after the other, similar to freight cars on a train. The wave train will continue to bring one low pressure system after another through the west coast, Great Basin and Rockies and into the central and Southern Plains.

The rainfall amounts across many areas of the United States have been very impressive since May 1. As you can see in the graphic below, precipitation has been most abundant in the central and southern plains and the Rockies.


Even some areas that really needed rain, such as the Dakotas, Nebraska and Minnesota have done very well. Even portions of southern California picked up 1 to 2 inches of rain in the last two weeks.
The most recent drought monitor shown below shows the persistent drought area in the Southern Plains is shrinking and that shrinkage will continue through the rest of May and into June as more wet weather is headed to Kansas, Oklahoma, Texas, New Mexico and Colorado. In fact, many areas of the United States will have excellent chances for more May precipitation. The driest areas of the country will be in the southeastern states, however, some rain is on the way in those areas as well.
Beef producers in Utah, Idaho, Oregon and Nevada can expect some more rain as well.
