ALPENA – Hot and humid.
That’s how Andy Sillivan, a meteorologist with the National Weather Service-Gaylord, described the weather in northeastern Michigan last month.
The month started a bit cool, but temperatures rebounded and a series of 11 consecutive days from August 6 to August 16 recorded temperatures of 80 degrees or more.
The highest temperature recorded in Alpena for the month was 91 degrees on 10 August.
For the month, the average temperature was 67.8 degrees, 2.4 degrees above the long-term average. The average high temperature was 78.9 degrees and the average low temperature was 56.8 degrees.
The coldest temperature recorded in Alpena last month came on Monday, when mercury dropped to 47 degrees overnight.
Both high and low average temperatures were above the historical average.
Sullivan said August pretty much followed suit of the other summer months, as it was very sunny and hot. He said the jet stream was maintained further north than normal, allowing warm southern air to move into the area and remain.
“It wasn’t as hot as July, but he kept thinking we’d have a hot summer overall,” Sullivan said. “We’re having the kind of summer they have in the Ohio Valley because of how far north the jet stream is.”
With the heat came high humidity, Sullivan said. There were also some pop-up thunderstorms, some of them violent, which produced strong winds and hail.
Sullivan said there was more rain than normal in August, as the area saw 3.51 inches of rain, eclipsing the historical average of 3.23 inches.
“We rained a lot, but that helped keep the grass nice and green, which is nice,” He said.
Now that the calendar has moved into September, cooler air is expected to enter more frequently.
Sullivan said Labor Day weekend will be cold Friday but will rise in the mid-70s from Saturday to Monday. He said there is also a small chance of rain showers on Sunday.
Beyond the holidays, Sullivan said the weather will vary for the rest of the month, with temperature changes as autumn approaches. He said the Climate Prediction Center has predicted September will drop below average, from a temperature standpoint.
It will be more volatile,“He said.”Temperatures will go from cool to warm and will rise and fall a lot. We should do some warming up, though, before autumn starts. “
