Title: North American Monsoon Kicks Into Gear

The expression, “better late than never” can apply to this summer’s North American Monsoon season. The cool spring and the cool start to the summer season in the far western states caused a delay in the onset of the thunderstorms that form in the Desert Southwest and Rockies in July and early August.

In addition to the Desert Southwest and Rockies, the thunderstorms are also prevalent in Mexico south into Central America. So far, rainfall in the above-mentioned areas has been below normal as the North American Monsoon was slow to start.

However, over the next few weeks, the moisture flow will increase, and the thunderstorm activity is going to pick up over the western USA and perhaps in some central areas of the USA as well.

The graphic below shows expected rainfall over the next two weeks. Note the heavier rains in portions of the Rockies and Desert Southwest. Also, note the increase in rain over Nebraska, Iowa, South Dakota and portions of Kansas and Missouri. In those areas, expect better rain chances over the next two to three weeks.
