A month of pleasant weather ended on the chilly side last week as October gave way to November. Despite one last blast of warm weather, the month ended below average in temperature and also below average in rainfall.

“The National Weather Service office in Toledo listed the monthly temperature at 0.7° below average,” said Morenci climate observer George Isobar. There were some warm extremes and some chilly extremes, but overall it was just a pretty nice month.”

The high of 79° was recorded Oct. 24 during a four-day stretch with temperatures in the 70s. 

“It stayed mild overnight, also, and gave daily averages of 15, 19 and 17 degrees above normal,” Isobar said. “It was nearly 60° two mornings in a row when I went out to collect data. That’s really unusual for Oct. 23 and 24.”

The coldest weather came much earlier in the month. The mercury dropped to 28° on the morning of Oct. 8 during a string of nine days that were all below average.

“There were a dozen morning lows in the 20s and 30s,” Isobar said. “On the other hand, there was a total of seven days in the 70s.”

Precipitation finished about a third of an inch below normal and was spread out among a lot of smaller storms.

“The biggest rain was only 64 hundredths of an inch,” Isobar said, “and that fell during one of the three thunderstorms last month.”

Isobar didn’t report any snowfall, but there was some sleet on the final day of the month.

NOVEMBER—”We’re still waiting for the first snowfall,” Isobar said. “Well, some people aren’t waiting, they’re dreading it.

“We’ve averaged a couple inches of snow in November over the last three decades, with a high of 6.6 inches.”

But on the other hand, he said, it ground often stays green.
