Transcript for Winter in Sight? Cold Snap Shatters Record
And now to the weather whiplash around the country. In a 24-hour period more than half the country has traded flip-flops for snow boots. Or t-shirts for sweaters. Temperatures plummeting so fast records are shattering from coast to coast. So what is the consequence of this and what does it mean for the winter ahead? Abc's weather editor sam champion tells us. Reporter: After suffering through the third hottest summer on record, a quick turnaround. A preseason blast of cold air bringing snow in early october from the rockies to new england. In vermont last week, tourists were enjoying fall foliage. Today, the red and gold is blanketed with white. Ushering in the snow are record lows.

Now, we believe there will be subtle change but more cold air waiting to come down. It was quick and does it necessarily mean anything for the winter ahead? First push is not an indicator for the rest of the season and you know I'm not a big fan of long-range forecasters but we are getting better at figuring out what the world trends will be predicting a long drought and we think a return to snow and winter weather on the east coast this winter.
