sioux falls, sd
We are entering the last month of meteorological summer. And the way we ended July will be the way we start August, with below average temperatures.
Numerous long-range models are putting much of the upper plains below average for the first two weeks of August. Keep in mind that this is the month when we start the see the average highs go down.
Sioux Falls is a slower decline when compared to the six-degree dip for Aberdeen, Pierre and Rapid City. By the end of the month, average highs are in the upper 70s to middle 80s.
The cooler air should give us better chances for rain as the atmosphere will have a hard time getting capped. A capped atmosphere means the heat keeps building on top of itself into the higher layers of the atmosphere and it's hard for storm clouds to form.
Average rain amounts vary from around three inches in southeast South Dakota to under two inches in western and central South Dakota. With cooler than average temps this month, it should help many locations get close to or above average rain.
Hopefully it will be enough to top off the crops before we go into harvest season.
