UPDATE June 25: All-time June 24-hour Precipitation Record Broken in Savannah, Minneapolis, Sioux City, and Omaha this June

An intense cluster of thunderstorms dropped 6.65” of rainfall in about a four-hour period on Monday afternoon and evening at Savannah’s International Airport. This is a new calendar day record for the month of June in Savannah. Radar estimated rainfall reached 10.45” in some areas of the Savannah metro region.

The previous June monthly record was 6.60” on June 29, 1999 and the daily record of 3.29”, set in 1884, was smashed. Official precipitation records for Savannah began in 1871, although monthly measurements exist for the years of 1840-1859 as well (before resuming for good in 1871). Savannah’s average June monthly precipitation is 5.95”.

The rain continued to accumulate in portions of Iowa, South Dakota, and Minnesota this past week. Sioux Falls, South Dakota improved upon its moniker of ‘wettest month on record’ with a June total of 13.44” as of June 23rd (+10.40” above normal for the month to date). This has obliterated their previous wettest month of 9.42” set back in May 1898 (by an extraordinary 43%!). The figure of 13.44” is also close to what Sioux Falls would normally receive for the entire year-to-date as of June 23rd. It is also considerably more than what fell during the city’s driest year on record: 10.44” in all of 1894.

Sioux City, Iowa has also surpassed its former all-time wettest month (any month) on record with 13.25” as of June 23rd (+10.23” above normal for the month to date). The previous monthly record for the city was 11.78” in May 1903. On June 14th, Sioux City picked up 5.05” of rainfall, its 2nd heaviest calendar day rainfall on record and just short of its all-time 24-hour record (for any month) of 5.50” set on July 17, 1972. The 5.05” was also a new June monthly calendar day record. Over the three-day period of June 14-16, 8.27” of rain fell.

Precipitation records date back to 1889 in Sioux City and 1893 in Sioux Falls.
