While some folks got more rain than was needed this weekend, others didn’t get much.
A storm dumped one to 2.5 inches in about 45 minutes in Sioux Falls. And that was one of the lighter downpours. Hayti saw nearly seven inches. A few other areas also got two to four inches of rain over the weekend.
But the atmosphere likes to keep all things in balance, so while there were downpours, other areas didn’t get much. Those areas can blame the drought that is already in place.
The ground conditions influence whether rain falls. If the ground is wet, rain and downpours are more likely. If the ground is dry, it’s usually is harder for rain to fall. And this effect can be seen clearly from this weekend’s rain.
The areas in the northeast that didn’t get rain just happen to be the same areas that have been highlighted as areas that are under a drought.
Eventually some light showers went over those areas. But the heavier rain had a hard time growing over the areas that had little moisture in the ground. Instead, they popped up in other areas just a few miles away.
