The Wilmette buoy returned to Lake Michigan earlier this week. But a few days before it departed, several of its biggest admirers stopped by to meet it at Lloyd Park in Winnetka, Illinois.
Wil, as some of the IISG scientists call it, lay prone in the parking lot withstanding the blustery winds and cold temperatures. The ugly weather didn’t stop the 10 or so Chicago-area sailors from coming to the open house, leaning in close and examining the body of the machine they’ve come to rely on after only one season.
One remarked at how much smaller it was than he thought. Others stood and posed with it for pictures.
It’s hard not to anthropomorphize the buoy. Once in the water, the weather and lake condition data and images it provides are like sage advice coming from a reliable friend.
“I’m with the Glencoe Boat Club and we were excited when it was put in,” Eric Brislawn of Buffalo Grove, Illinois said. “We’ve been watching data on it all summer and using it. We—the boaters, the sailors up here—had nothing like this anywhere nearby…so this really filled a nice gap for weather information.”
The buoy might not have made it in the water without the help of Laurie Morse of Glencoe, Illinois, who along with Purdue University, helped secure a grant to fund it.
“We have already noticed since it’s been in the water since 2015 that it’s made a difference in the quality of our marine forecast and it’s really important to all us recreational boaters,” said Morse, who was with her husband at the open house.
“Well, we look for it in the water,” Morse remarked. “I’ve never been successful in finding it on the lake, but this is the first time I’ve seen the buoy. So this is very exciting.”
Jay Beugly, IISG aquatic ecology specialist, and scientists Ed Verhamme and John Bratton from LimnoTech, organized the open house and were on hand to talk about all the nearshore environmental-sensing this bright yellow, 610-pound buoy is capable of.
“We were happy that people came with lots of questions. Some didn’t know much about it. Others followed it closely last year,” said Beugly. “This is the first full season that this buoy will be deployed, and we want people to know that it’s out there. We were excited to be able to stand next to the buoy while it’s out of the water and talk to folks and see how we might improve their experience.”
With that nip in the air and the occasional snow flurries, it’s hard to deny that winter is almost here. Will this year be as cold as last? Molly Woloszyn tackles this complicated question.
After a mild start to fall, November abruptly turned cold in the Midwest, giving us an early dose of winter. One of the coldest days was November 17th, when maximum daily temperatures of less than 30°F were widespread across the region—parts of southern Minnesota and northern Iowa only reached the single digits. With a preliminary average temperature of 31.4°F, November 2014 is now the Midwest’s sixth coldest November since records began in 1895.
But things are shaping up to be a little different for December. In fact, NOAA’s Climate Prediction Center (CPC) is now predicting a pattern change for at least the next two weeks. This means there’s a good chance that a majority of the United States will experience much milder conditions, with above-normal temperatures expected through the middle of the month. This isn’t necessarily surprising. We have a couple of examples in the past where record cold Novembers gave way to normal or warmer winters.
So, the question on all of our minds is “What does the rest of the 2014-2015 winter have in store for us Midwesterners?”
I wish I had a formula to tell you exactly what to expect. Accurate seasonal outlooks are always difficult to provide. But predictions are especially difficult this year because there is no strong signal or driver in the atmosphere.
What do I mean by “signal” or “driver”? I am talking about phenomenon like El Niño, which is the existence of unusually warm sea surface temperatures in the equatorial Pacific Ocean. Believe it or not, this can have major implications across the country. In the Midwest, winters tend to be warmer than normal—and drier in some places—when there is a strong El Niño. There is a 65 percent chance El Niño could develop this winter. However, if it emerges, it is likely to be weak, making it an undependable driver when it comes to this winter’s outlook.
A few seasonal outlook approaches are pointing to the possibility for a colder-than-normal winter in the Midwest. For instance, some research suggests that there is a strong correlation between rapid snow advancement and its overall extent across Siberia and Eurasia during October and colder-than-normal winter temperatures and more snowfall in the eastern United States. In October 2014, snow cover advance and extent across Eurasia was the 2nd highest in the satellite era, suggesting it could be a cold and snowy winter here in the Midwest.
This prediction is supported by another phenomenon we are seeing in the central and northern Pacific Ocean. A positive Pacific Decadal Oscillation (PDO), which represents a warmer-than-normal pattern of sea surface temperatures, tends to encourage colder conditions in the eastern US. The PDO has been predominantly negative since the late 1990s, but it shifted to positive in 2014.
Even if a colder winter is in our future, it may not necessarily be a white one. NOAA’s CPC is predicting greater chances of below-normal precipitation in portions of the eastern Midwest, which is also related to the possibility for weak El Niño development. There is no clear signal for the rest of the region.
Of course, we will have more information on winter weather predictions as they come in. In the meantime, enjoy the more mild temperatures most likely in store for the next few weeks.
