waether patterns

I started running down that line of thought, but only a moment later the wind picked up into a stiff, whistling breeze that roared through the air and swept down through the city. I frowned at the sudden shift in the weather and looked around.
I didn't find anything obvious, but when I glanced up, I saw the lights going out. A vast cloud bank was racing north, fast enough that I could see it eating the stars. A second wall of clouds was sailing south, toward the first bank. They met in only moments, and as they did, light flashed from cloud to cloud, brighter than daylight, and thunder shook the balcony beneath my feet. Not long after that, a drop of freezing-cold water landed on my head, quickly followed by a mounting torrent of chilly rain. The still-rising wind whipped it into a miserable downpour.
I turned and pulled open the door into the apartment with a frown. The Alphas were peering out windows, speaking quietly with one another. Across the room, Billy finished messing around with a television, and a rather rumpled-looking weatherman appeared, the image flickering with interference lines and bursts of snow.
"Guys, guys," Billy said. "Hush, let me listen." He turned up the volume.
"... a truly unprecedented event, an enormous Arctic blast that came charging like a freight train through Canada and across Lake Michigan to Chicagoland. And if that wasn't enough, a tropical front, settled quietly in the Gulf of Mexico, has responded in kind, rushing up the Mississippi River in a sudden heat wave. They've met right over Lake Michigan, and we have received several reports of rain and bursts of hail. Thunderstorm warnings have been issued all through the Lake Michigan area, and a tornado watch is in progress for the next hour in Cook Country. National Weather Service has also issued a flash flood warning and a travel advisory for the eastern half of Illinois. This is some beautiful but very violent weather, ladies and gentlemen, and we urge you to remain in shelter until this storm has time to ..."
Billy turned the volume down. I looked around the room and found nearly a dozen sets of eyes focused on me, patient and trusting. Bah.
"Harry," Billy said at last, "that isn't a natural storm, is it?"
I shook my head, got another Coke out of the cooler, and headed tiredly for the door. "Side effect. Like the toads."
"What does it mean?"
I opened the door and said, without looking back, "It means we're running out of time."
