DENVER, DEC. 28 -- This is a tough town for weather forecasters.

In summer, they say virtually the same thing day after day: "Tomorrow we can expect more of the same. Sunny skies with the possibility of brief afternoon thunderstorms."

But winter can be a humbling experience. Take Larry Green, weatherman for KCNC-TV.

Sunday night, he stood before the camera and admitted to viewers that he was just as surprised as they were that the storm had clobbered the city.

Appearing a bit sheepish on the 10 o'clock news -- a program dominated by reports of the snow and the havoc it was creating -- the normally sunny Green said his radar had missed a low pressure system that was lurking in the higher reaches of the atmosphere.

"Even the National Weather Service missed it," Green told his viewers.

"We underestimated the storm," weather service spokesman Jim Kaplan said. "A part of last week's storm moved to the east; the other part moved to southern California and then moved back this way. We thought it would get weaker, but it got stronger for reasons we still can't explain.

"Up until this storm, we've been batting 100 percent," Kaplan said. "But we get fooled from time to time."

This morning, people dug out cars under nearly two feet of snow. By afternoon, the sun and snowplows improved conditions, but more snow was expected Wednesday night and Thursday.

"We're predicting some snow, but nothing unusual," Kaplan said. "How much? Based on the last week's experience, I'd say it's pointless to speculate at this point."
