Taking A Look At August Weather Outlook


We just started the last month of meteorological summer.  Even though we’re slightly cooler than average, that will soon change.  But it may not last for the whole month.

Temperatures cooled during the last week of July and while that cool air is hanging around for the beginning of August, just wait for the first weekend of the month.  That’s when we’re return to summertime heat and humidity.  Along with that will come a chance for strong to severe weather.

While the heat will last into next week, the challenge will be for it to last beyond that.

August is the month when our average highs start going down.  As you can see, many areas start in the middle 80s to 90 degrees, but we’ll fall four to six degrees by the end of the month which puts average highs in the 70s for some in KELOLAND.  I think this month will follow that trend with warmer than average air most likely during the first half of the month, but the second half will see much cooler air.

As far as rain is concerned, the average amount of rain goes from nearly inches inches in Sioux Falls to around an inch and a half in Rapid City.  I think the best chance for above average rainfall will be southern KELOLAND.  And it may happen as early as this weekend as we get strong storms to develop.   

Some of those storms may also be severe.  As I reported earlier this week, KELOLAND still averages around 300 severe storm reports in the month of August.
