September Outlook

Temperatures will feel more like fall later this week

And while we started the month off hot, we'll experience more and more hits of cooler air throughout the month. The first will arrive Wednesday with another cool down on Friday. 

Many locations in KELOLAND experience average highs decreasing by 12 degrees from the first of September to the last.  Average lows also fall by ten to 14 degrees, eventually falling to near 40 degrees by the September 30.

Overnight lows will have to be watched as the month goes on. Because we've had such a dry summer, it will be a lot easier to cool off at night and KELOLAND might even get an early frost.

On average, a frost occurs in KELOLAND during the last week of September or first week of October.  

As far as rain goes, when the hits of cooler air move in, we'll have chances for rain.

What we need is low pressure to move in from the southwest at the same time a cold front moves in from the north. This would give us our best chance for much needed widespread rain. 

But, most locations will stay below average for rain this month. KELOLAND averages as little as just over an inch in Rapid City to as much as two and three quarter inches in Sioux Falls.

Any rain will be beneficial, but we'll need well above average rain this month to make a dent in the current drought.
