Isobar looks at April weather 2012.05.09

If it weren’t for the rain on the final day of the month, there wouldn’t have been much in the way of April Showers at all.

“Rainfall was below average last month,” said Morenci climate observer George Isobar, “but if we hadn’t gotten .62 inches on April 30, it would have been way, way below.”

Precipitation for the month finished off at 1.98 inches, far below the average of 3.6 inches.

“We never really had a big rain all month,” Isobar said. “We only had a quarter inch through the first half of the month and never even crossed the inch mark until April 25.”

There was a little snow that fell, just like rural Morenci resident George Hollstein predicted. It never fails, he said. There are always a few flakes after he returns to Michigan from Florida, he said, and this year was no exception.

This year it didn’t seem so likely after the extra warm March, but the spring weather disappeared and the temperature never made it out of the 60s until April 15 with the month’s high of 81°.

Even that didn’t last long. It was back in the 60s the next day and soon down into the 50s. If that wasn’t unspring-like enough, the high temperature on April 28 was only 45°.

“One day in the 80s, two days in the 70s—everything else colder,” Isobar said. 

The coolest temperature came late in the month when the mercury sank to 27° on the 27th.

“What really surprised me was that the chilly April wasn’t really that unusual at all,” Isobar said. “I guess it was the warm March that threw me off, but the National Weather Service office at Toledo Express Airport  shows the departure from normal at one-tenth of a degree above normal. I was expecting to see a number below average.”

A trace of snow fell April 10 and only one thunderstorm was recorded, on the final day of the month.

MAY—“It looks like we were spoiled with that 89° day last week,” Isobar said. “Who knows—that might turn out to be the high temperature for the month.”

There’s nothing in the forecast for temperatures in the 80s for the next weeks, and by then the month will be half over already.

The big question is how the rainfall will turn out. About 1.2 inches has fallen in the last week. Is that a sign of what’s to come or will we go back to dodging storms like we did in April?
