CEDAR RAPIDS, Iowa (KCRG-TV9) - While June is one of our wettest months on average, July and August are the wettest of the year for the Desert Southwest. These months are important for that part of the country because over half the year’s rainfall routinely comes from those two months. It can also help to bring relief to intense heat and sun. On the flip side, flash flooding can also occur during times of torrential rainfall.
By the way, a “monsoon” is not a torrential rain event as many believe it to be. It’s a seasonal wind shift that allows for a wetter pattern to become favorable.
The monsoon does have an impact on the Midwest. Occasionally, some waves of low pressure move into Iowa from there. More times than not, though, our weather starts to dry out somewhat as high pressure remains pretty common.
As you can see from the graphic, the next nine days will be pretty dry around here. That’s welcome news for our area rivers. The Southwest will start to experience more stormy weather and given the severe drought in that part of the country, flash flooding may occur because very dry ground doesn’t absorb very heavy rain well.
