When the rain came, it came in buckets. And the temperature? It was all over the place.

“That’s how spring often is in this part of the country,” said Morenci climate observer George Isobar.

Isobar records temperature and precipitation data as a cooperative observer for the National Weather Service.

Isobar said there was a 60° difference between the high and low temperatures last month. April started with record-setting high temperatures, but soon plunged to the low for the month with 24° on the 10th.

For Toledo’s long-term records, an 83° reading April 6 tied the record set in 1929. On the first day of the month, 80° set a new record, topping the 1986 mark of 79°.

“It was a rather remarkable month for temperature data,” Isobar said. “There were five April days in the 80s and the average for the month came in 6.1° higher. That’s a lot.”

Isobar said a typical month might come in between one degree above average to one degree below. Six degrees above shows it was really unusual.

The high temperature for the month came April 15 at 84°.

“We had two morning temperatures in the first week of the month that started off in the 60s,” Isobar said. “It was feeling like summer for a few days.”

But back to that statement about temperatures being all over the place. It wasn’t warm all the time. There were also nine days that produced below average totals. There were 12 morning readings that started off at or below freezing.

Rainfall came in about seven-tenths of an inch above the average at 4.63 inches, but there’s something a little odd about that, too.

“That’s a lot of rain, even for April, but it nearly all came in two storms,” he said. “Other than that we had about a quarter of an inch.”

On April 7, 1.42 inches fell. On April 24 and 25, 2.94 inches fell.

There were three storms with thunder and, fess up, Isobar, there was a little snow that fell.

“Yes, I remember my foolish prediction that it wouldn’t snow in April,” Isobar said. “I was affected by the heat.”

Overnight on April 9, sleet fell and traces were still on rooftops in the morning. A few chilly days later on April 13, Isobar said he noticed a few flakes falling. Just a few.

MAY—“I don’t expect any snow this month,” he said.

Safe bet. There’s only been one May snowstorm recorded in this area in many decades.

“About half of the recent Mays we’ve had a high temperature in the 90s,” Isobar said. “Rarer is a low morning temperature in the 20s, but it happens now and then.”

The interesting thing to watch, Isobar said, is if the more extreme storms keep coming.

“When it rains, it really rains,” he said, “sort of like our two storms last month.”
