Bloomington climate trends could mean wetter summers, higher lake levels

Three decades from now, Indiana is forecast to see between 6 and 8 percent more rainfall than it averaged in the past, depending on the amount of greenhouse gas emissions during the lead-up to mid-century.

That’s according to a 2018 report from the Purdue Climate Change Research Center.

According to the report, in southern Indiana, the increased precipitation is predicted to come more in the winter and spring months.

But based on records of precipitation and the water levels at Lake Monroe in the past two and a half decades, southern Indiana looks like it could be seeing more rain in the first half of summer.

Earlier this week, the Indianapolis office of the National Weather Service tweeted out a link to a report on the anomaly of this summer’s first half: It has been way wetter than normal.

The abnormal amount of region-wide rainfall has caused high water on Lake Monroe. Last week Indiana’s Department of Natural Resources closed the swim beaches at the lake’s Fairfax SRA and Paynetown SRA and they’ve stayed closed.

Rainfall and lake levels are related, of course. And over the last quarter century, both seem to be showing an upward trend for this time of year. Continue reading “Bloomington climate trends could mean wetter summers, higher lake levels”

Bloomington three-day rain total: 5.26 inches (17th rainiest three-day span on record)

The heavy rain that fell on Bloomington and the surrounding area on Thursday, Feb. 7 totaled 3.3 inches, based on data reported by the National Weather Service station on Indiana University’s campus.

That one-day total made yesterday the 28th rainiest day in Bloomington, since Nov. 16, 1895, when the station started keeping records. Yesterday’s 3.3 inches was only about half as much as the 6.56 inches that fell on Oct. 6, 1910, which remains the rainiest Bloomington day on record.
