EPIC SNOW to a HURRICANE: How did this happen in days?
Thursday, July 12, 2018, 9:30 AM - As Newfoundland braces for impact from Post Tropical Storm Chris, it's hard to believe (or maybe not) that just 16 days ago parts of the island were digging out of summer SNOW. Driving alerts and frost advisories were also in place at the end of June. So what happened?
"If you live in Newfoundland, you know the weather can drastically change in not just weeks, but days and hours," says Weather Network meteorologist Erin Wenckstern. "Even after the impressive summer snow in late June, the island was basking in temperatures into the 20s a couple of days later."
And it was THIS transition from snow to extreme heat in just a matter of days that set up the perfect breeding grounds for a hurricane. Forecasters were calling it a heat dome -- a term for a large, expansive ridge in the upper atmosphere that would leave stagnant hot weather for a long period of time.
"See the trick with tropical development is that the storms enjoy feasting on warm ocean waters, but despise chaotic winds," Wenckstern explains. "The heat dome catered to these demands and over this past weekend, our third named storm Chris was born in the warm waters off the Carolinas."
Shortly after reaching Category 2 hurricane strength, Chris hopped north of the Gulf Stream, encountered painfully cooler waters and is now in the process of transitioning into a post-tropical cyclone as it heads for St. Mary's Bay, Newfoundland.
"Again, just 16 days after our EPIC summer snowfall," Wenckstern says.
