At the tail end of one of the hottest summers on record, we experienced record lows.
All considering, this should come as no surprise due to the very dry ground we have during the hot summer. Not only is dry air easy to warm during the day, but it's also easy to cool at night. For that reason, one of the first hits of Canadian air this year has allowed areas to experience record lows.
Here's a sample of some of the records. Aberdeen hit 39 degrees, and it was 40 degrees in Sioux Falls and Huron. It fell to 41 degrees in Pierre and 42 degrees in Sisseton.
We've seen this before. For example, July 2002 was a hot month with the average high temperature in Sioux Falls close to 90 degrees. The following August produced a record low of 44 degrees on August 18. Aberdeen also set a record at 38 degrees that morning; along with Pierre, Watertown, Huron, and Mitchell all setting record lows that morning.
It is interesting to know, before our record cold Friday morning, we set a record high this month too. On the first of the month, Sioux Falls hit 102 degrees. But record highs and lows have happened in August before.
It happened in 1934 when Sioux Falls set a record high of 107 on August 4 to a record low of 39 degrees on August 24.
This also happened in 1896 and 1970. The interesting thing about 1970 is we went from a record high of 99 degrees on August 14 to a record low two days later of 48 degrees, and then back to a record high of 99 degrees on August 29.
We'll see if we have such a ride later this month.
